+ ### Because WordPress is awesome, but the_loop isn't
8
+ Timber helps you create fully-customized WordPress themes faster with more sustainable code. With Timber, you write your HTML using the [Twig Template Engine](http://twig.sensiolabs.org/) separate from your PHP files.
9
+
10
+ This cleans-up your theme code so, for example, your php file can focus on being the data, while your twig/html file can focus 100% on the HTML and display.
11
+
12
+ Once Timber is installed and activated in your plugin directory, it gives any WordPress theme the ability to take advantage of the power of Twig and other Timber features.
13
+
14
+ ### Looking for docs?
15
+ * [Timber Documentation](https://github.com/jarednova/timber/wiki/)
16
+ * [Twig Reference](http://twig.sensiolabs.org/documentation)
17
+ * **[Video Tutorials](https://github.com/jarednova/timber/wiki/Video-Tutorials)**
18
+ * [Overview / Getting Started Guide](https://github.com/jarednova/timber/wiki/getting-started)
19
+
20
+ #### What does it look like?
21
+ Nothing. Timber is meant for you to build a theme on. Like the [Starkers](https://github.com/viewportindustries/starkers) or [Boilerplate theme](https://github.com/zencoder/html5-boilerplate-for-wordpress) it comes style-free, because you're the style expert. Instead, Timber handles the logic you need to make a kick-ass looking site.
22
+
23
+ #### Who is it good for?
24
+ Timber is great for any WordPress developer who cares about writing good, maintainable code. It helps teams of designers and developers working together. At [Upstatement](http://upstatement.com) we made Timber because not everyone knows the ins-and-outs of the_loop(), WordPress codex and PHP (nor should they). With Timber your best WordPress dev can focus on building the .php files with requests from WordPress and pass the data into .twig files. Once there, designers can easily mark-up data and build out a site's look-and-feel.
25
+
26
+ #### Should I use it?
27
+ Well, it's **free**! And it's GPL-licensed, so use in personal or commerical work. Just don't re-sell it.
28
+
29
+ #### Upgrade Notes
30
+ Twig is no longer a submodule, just a part of the repo. If you have trouble pulling, just delete the `Twig` folder. Then you should be good.
31
+ In May 2013 there was a major rewrite of Timber. Trust me, it's worth it. But if you're looking for the old [Parent Theme Timber](https://github.com/jarednova/timber/tree/theme) you can still find it on this [branch](https://github.com/jarednova/timber/tree/theme).

+ * 0.9.10 (2010-12-16)
356
+
357
+ Backward incompatibilities:
358
+
359
+ * The Escaper extension is enabled by default, which means that all displayed
360
+ variables are now automatically escaped. You can revert to the previous
361
+ behavior by removing the extension via $env->removeExtension('escaper')
362
+ or just set the 'autoescape' option to 'false'.
363
+ * removed the "without loop" attribute for the "for" tag (not needed anymore
364
+ as the Optimizer take care of that for most cases)
365
+ * arrays and hashes have now a different syntax
366
+ * arrays keep the same syntax with square brackets: [1, 2]
367
+ * hashes now use curly braces (["a": "b"] should now be written as {"a": "b"})
368
+ * support for "arrays with keys" and "hashes without keys" is not supported anymore ([1, "foo": "bar"] or {"foo": "bar", 1})
369
+ * the i18n extension is now part of the Twig Extensions repository
370
+
371
+ Changes:
372
+
373
+ * added the merge filter
374
+ * removed 'is_escaper' option for filters (a left over from the previous version) -- you must use 'is_safe' now instead
375
+ * fixed usage of operators as method names (like is, in, and not)
376
+ * changed the order of execution for node visitors
377
+ * fixed default() filter behavior when used with strict_variables set to on
378
+ * fixed filesystem loader compatibility with PHAR files
379
+ * enhanced error messages when an unexpected token is parsed in an expression
380
+ * fixed filename not being added to syntax error messages
381
+ * added the autoescape option to enable/disable autoescaping
382
+ * removed the newline after a comment (mimicks PHP behavior)
383
+ * added a syntax error exception when parent block is used on a template that does not extend another one
384
+ * made the Escaper extension enabled by default
385
+ * fixed sandbox extension when used with auto output escaping
386
+ * fixed escaper when wrapping a Twig_Node_Print (the original class must be preserved)
387
+ * added an Optimizer extension (enabled by default; optimizes "for" loops and "raw" filters)
388
+ * added priority to node visitors
389
+
390
+ * 0.9.9 (2010-11-28)
391
+
392
+ Backward incompatibilities:
393
+ * the self special variable has been renamed to _self
394
+ * the odd and even filters are now tests:
395
+ {{ foo|odd }} must now be written {{ foo is odd }}
396
+ * the "safe" filter has been renamed to "raw"
397
+ * in Node classes,
398
+ sub-nodes are now accessed via getNode() (instead of property access)
399
+ attributes via getAttribute() (instead of array access)
400
+ * the urlencode filter had been renamed to url_encode
401
+ * the include tag now merges the passed variables with the current context by default
402
+ (the old behavior is still possible by adding the "only" keyword)
403
+ * moved Exceptions to Twig_Error_* (Twig_SyntaxError/Twig_RuntimeError are now Twig_Error_Syntax/Twig_Error_Runtime)
404
+ * removed support for {{ 1 < i < 3 }} (use {{ i > 1 and i < 3 }} instead)
405
+ * the "in" filter has been removed ({{ a|in(b) }} should now be written {{ a in b }})
406
+
407
+ Changes:
408
+ * added file and line to Twig_Error_Runtime exceptions thrown from Twig_Template
409
+ * changed trans tag to accept any variable for the plural count
410
+ * fixed sandbox mode (__toString() method check was not enforced if called implicitly from complex statements)
411
+ * added the ** (power) operator
412
+ * changed the algorithm used for parsing expressions
413
+ * added the spaceless tag
414
+ * removed trim_blocks option
415
+ * added support for is*() methods for attributes (foo.bar now looks for foo->getBar() or foo->isBar())
416
+ * changed all exceptions to extend Twig_Error
417
+ * fixed unary expressions ({{ not(1 or 0) }})
418
+ * fixed child templates (with an extend tag) that uses one or more imports
419
+ * added support for {{ 1 not in [2, 3] }} (more readable than the current {{ not (1 in [2, 3]) }})
420
+ * escaping has been rewritten
421
+ * the implementation of template inheritance has been rewritten
422
+ (blocks can now be called individually and still work with inheritance)
423
+ * fixed error handling for if tag when a syntax error occurs within a subparse process
424
+ * added a way to implement custom logic for resolving token parsers given a tag name
425
+ * fixed js escaper to be stricter (now uses a whilelist-based js escaper)
426
+ * added the following filers: "constant", "trans", "replace", "json_encode"
427
+ * added a "constant" test
428
+ * fixed objects with __toString() not being autoescaped
429
+ * fixed subscript expressions when calling __call() (methods now keep the case)
430
+ * added "test" feature (accessible via the "is" operator)
431
+ * removed the debug tag (should be done in an extension)
432
+ * fixed trans tag when no vars are used in plural form
433
+ * fixed race condition when writing template cache

437
+ * fixed Twig_Template::getAttribute() for protected properties
438
+
439
+ * 0.9.8 (2010-06-28)
440
+
441
+ Backward incompatibilities:
442
+ * the trans tag plural count is now attached to the plural tag:
443
+ old: `{% trans count %}...{% plural %}...{% endtrans %}`
444
+ new: `{% trans %}...{% plural count %}...{% endtrans %}`
445
+
446
+ * added a way to translate strings coming from a variable ({% trans var %})
447
+ * fixed trans tag when used with the Escaper extension
448
+ * fixed default cache umask
449
+ * removed Twig_Template instances from the debug tag output
450
+ * fixed objects with __isset() defined
451
+ * fixed set tag when used with a capture
452
+ * fixed type hinting for Twig_Environment::addFilter() method
453
+
454
+ * 0.9.7 (2010-06-12)
455
+
456
+ Backward incompatibilities:
457
+ * changed 'as' to '=' for the set tag ({% set title as "Title" %} must now be {% set title = "Title" %})
458
+ * removed the sandboxed attribute of the include tag (use the new sandbox tag instead)
459
+ * refactored the Node system (if you have custom nodes, you will have to update them to use the new API)
460
+
461
+ * added self as a special variable that refers to the current template (useful for importing macros from the current template)
462
+ * added Twig_Template instance support to the include tag
463
+ * added support for dynamic and conditional inheritance ({% extends some_var %} and {% extends standalone ? "minimum" : "base" %})
464
+ * added a grammar sub-framework to ease the creation of custom tags
465
+ * fixed the for tag for large arrays (some loop variables are now only available for arrays and objects that implement the Countable interface)
466
+ * removed the Twig_Resource::resolveMissingFilter() method
467
+ * fixed the filter tag which did not apply filtering to included files
468

470
+ * added a sandbox tag in the sandbox extension
471
+ * changed the date filter to support any date format supported by DateTime

473
+ * added the lexer, parser, and compiler as arguments to the Twig_Environment constructor
474
+ * changed the cache option to only accepts an explicit path to a cache directory or false
475
+ * added a way to add token parsers, filters, and visitors without creating an extension
476
+ * added three interfaces: Twig_NodeInterface, Twig_TokenParserInterface, and Twig_FilterInterface
477
+ * changed the generated code to match the new coding standards
478
+ * fixed sandbox mode (__toString() method check was not enforced if called implicitly from a simple statement like {{ article }})
479
+ * added an exception when a child template has a non-empty body (as it is always ignored when rendering)
480
+
481
+ * 0.9.6 (2010-05-12)
482
+
483
+ * fixed variables defined outside a loop and for which the value changes in a for loop
484
+ * fixed the test suite for PHP 5.2 and older versions of PHPUnit

495
+ * added support for escaping strategy in the autoescape tag
496
+ * fixed lexer when a template has a big chunk of text between/in a block
497
+
498
+ * 0.9.5 (2010-01-20)
499
+
500
+ As for any new release, don't forget to remove all cached templates after
501
+ upgrading.
502
+
503
+ If you have defined custom filters, you MUST upgrade them for this release. To
504
+ upgrade, replace "array" with "new Twig_Filter_Function", and replace the
505
+ environment constant by the "needs_environment" option:
506
+
507
+ // before
508
+ 'even' => array('twig_is_even_filter', false),
509
+ 'escape' => array('twig_escape_filter', true),
510
+
511
+ // after
512
+ 'even' => new Twig_Filter_Function('twig_is_even_filter'),
513
+ 'escape' => new Twig_Filter_Function('twig_escape_filter', array('needs_environment' => true)),
514
+
515
+ If you have created NodeTransformer classes, you will need to upgrade them to
516
+ the new interface (please note that the interface is not yet considered
517
+ stable).
518
+
519
+ * fixed list nodes that did not extend the Twig_NodeListInterface
520
+ * added the "without loop" option to the for tag (it disables the generation of the loop variable)
521
+ * refactored node transformers to node visitors
522
+ * fixed automatic-escaping for blocks
523
+ * added a way to specify variables to pass to an included template
524
+ * changed the automatic-escaping rules to be more sensible and more configurable in custom filters (the documentation lists all the rules)
525
+ * improved the filter system to allow object methods to be used as filters
526
+ * changed the Array and String loaders to actually make use of the cache mechanism
527
+ * included the default filter function definitions in the extension class files directly (Core, Escaper)
528
+ * added the // operator (like the floor() PHP function)
529
+ * added the .. operator (as a syntactic sugar for the range filter when the step is 1)
530
+ * added the in operator (as a syntactic sugar for the in filter)
531
+ * added the following filters in the Core extension: in, range
532
+ * added support for arrays (same behavior as in PHP, a mix between lists and dictionaries, arrays and hashes)
533
+ * enhanced some error messages to provide better feedback in case of parsing errors
534
+
535
+ * 0.9.4 (2009-12-02)
536
+
537
+ If you have custom loaders, you MUST upgrade them for this release: The
538
+ Twig_Loader base class has been removed, and the Twig_LoaderInterface has also
539
+ been changed (see the source code for more information or the documentation).
540
+
541
+ * added support for DateTime instances for the date filter
542
+ * fixed loop.last when the array only has one item
543
+ * made it possible to insert newlines in tag and variable blocks
544
+ * fixed a bug when a literal '\n' were present in a template text
545
+ * fixed bug when the filename of a template contains */
546
+ * refactored loaders
547
+
548
+ * 0.9.3 (2009-11-11)
549
+
550
+ This release is NOT backward compatible with the previous releases.
551
+
552
+ The loaders do not take the cache and autoReload arguments anymore. Instead,
553
+ the Twig_Environment class has two new options: cache and auto_reload.
554
+ Upgrading your code means changing this kind of code:
555
+
556
+ $loader = new Twig_Loader_Filesystem('/path/to/templates', '/path/to/compilation_cache', true);
557
+ $twig = new Twig_Environment($loader);
558
+
559
+ to something like this:
560
+
561
+ $loader = new Twig_Loader_Filesystem('/path/to/templates');
562
+ $twig = new Twig_Environment($loader, array(
563
+ 'cache' => '/path/to/compilation_cache',
564
+ 'auto_reload' => true,
565
+ ));
566
+
567
+ * deprecated the "items" filter as it is not needed anymore
568
+ * made cache and auto_reload options of Twig_Environment instead of arguments of Twig_Loader
569
+ * optimized template loading speed
570
+ * removed output when an error occurs in a template and render() is used
571
+ * made major speed improvements for loops (up to 300% on even the smallest loops)
572
+ * added properties as part of the sandbox mode
573
+ * added public properties support (obj.item can now be the item property on the obj object)
574
+ * extended set tag to support expression as value ({% set foo as 'foo' ~ 'bar' %} )
575
+ * fixed bug when \ was used in HTML
576
+
577
+ * 0.9.2 (2009-10-29)
578
+
579
+ * made some speed optimizations
580
+ * changed the cache extension to .php
581
+ * added a js escaping strategy
582
+ * added support for short block tag
583
+ * changed the filter tag to allow chained filters
584
+ * made lexer more flexible as you can now change the default delimiters
585
+ * added set tag
586
+ * changed default directory permission when cache dir does not exist (more secure)
587
+ * added macro support
588
+ * changed filters first optional argument to be a Twig_Environment instance instead of a Twig_Template instance
589
+ * made Twig_Autoloader::autoload() a static method
590
+ * avoid writing template file if an error occurs
591
+ * added $ escaping when outputting raw strings
592
+ * enhanced some error messages to ease debugging
593
+ * fixed empty cache files when the template contains an error

+
597

598
+ * fixed numbers with one than one decimal
599
+ * added support for method calls with arguments ({{ foo.bar('a', 43) }})
600
+ * made small speed optimizations
601
+ * made minor tweaks to allow better extensibility and flexibility
602
+
603
+ * 0.9.0 (2009-10-12)
604
+

1
+ Extending Twig
2
+ ==============
3
+
4
+ .. caution::
5
+
6
+ This section describes how to extend Twig as of **Twig 1.12**. If you are
7
+ using an older version, read the :doc:`legacy<advanced_legacy>` chapter
8
+ instead.
9
+
10
+ Twig can be extended in many ways; you can add extra tags, filters, tests,
11
+ operators, global variables, and functions. You can even extend the parser
12
+ itself with node visitors.
13
+
14
+ .. note::
15
+
16
+ The first section of this chapter describes how to extend Twig easily. If
17
+ you want to reuse your changes in different projects or if you want to
18
+ share them with others, you should then create an extension as described
19
+ in the following section.
20
+
21
+ .. caution::
22
+
23
+ When extending Twig without creating an extension, Twig won't be able to
24
+ recompile your templates when the PHP code is updated. To see your changes
25
+ in real-time, either disable template caching or package your code into an
26
+ extension (see the next section of this chapter).
27
+
28
+ Before extending Twig, you must understand the differences between all the
29
+ different possible extension points and when to use them.
30
+
31
+ First, remember that Twig has two main language constructs:
32
+
33
+ * ``{{ }}``: used to print the result of an expression evaluation;
34
+
35
+ * ``{% %}``: used to execute statements.
36
+
37
+ To understand why Twig exposes so many extension points, let's see how to
38
+ implement a *Lorem ipsum* generator (it needs to know the number of words to
39
+ generate).
40
+
41
+ You can use a ``lipsum`` *tag*:
42
+
43
+ .. code-block:: jinja
44
+
45
+ {% lipsum 40 %}
46
+
47
+ That works, but using a tag for ``lipsum`` is not a good idea for at least
48
+ three main reasons:
49
+
50
+ * ``lipsum`` is not a language construct;
51
+ * The tag outputs something;
52
+ * The tag is not flexible as you cannot use it in an expression:
53
+
54
+ .. code-block:: jinja
55
+
56
+ {{ 'some text' ~ {% lipsum 40 %} ~ 'some more text' }}
57
+
58
+ In fact, you rarely need to create tags; and that's good news because tags are
59
+ the most complex extension point of Twig.
60
+
61
+ Now, let's use a ``lipsum`` *filter*:
62
+
63
+ .. code-block:: jinja
64
+
65
+ {{ 40|lipsum }}
66
+
67
+ Again, it works, but it looks weird. A filter transforms the passed value to
68
+ something else but here we use the value to indicate the number of words to
69
+ generate (so, ``40`` is an argument of the filter, not the value we want to
70
+ transform).
71
+
72
+ Next, let's use a ``lipsum`` *function*:
73
+
74
+ .. code-block:: jinja
75
+
76
+ {{ lipsum(40) }}
77
+
78
+ Here we go. For this specific example, the creation of a function is the
79
+ extension point to use. And you can use it anywhere an expression is accepted:
80
+
81
+ .. code-block:: jinja
82
+
83
+ {{ 'some text' ~ lipsum(40) ~ 'some more text' }}
84
+
85
+ {% set lipsum = lipsum(40) %}
86
+
87
+ Last but not the least, you can also use a *global* object with a method able
88
+ to generate lorem ipsum text:
89
+
90
+ .. code-block:: jinja
91
+
92
+ {{ text.lipsum(40) }}
93
+
94
+ As a rule of thumb, use functions for frequently used features and global
95
+ objects for everything else.
96
+
97
+ Keep in mind the following when you want to extend Twig:
98
+
99
+ ========== ========================== ========== =========================
100
+ What? Implementation difficulty? How often? When?
101
+ ========== ========================== ========== =========================
102
+ *macro* trivial frequent Content generation
103
+ *global* trivial frequent Helper object
104
+ *function* trivial frequent Content generation
105
+ *filter* trivial frequent Value transformation
106
+ *tag* complex rare DSL language construct
107
+ *test* trivial rare Boolean decision
108
+ *operator* trivial rare Values transformation
109
+ ========== ========================== ========== =========================
110
+
111
+ Globals
112
+ -------
113
+
114
+ A global variable is like any other template variable, except that it's
115
+ available in all templates and macros::
116
+
117
+ $twig = new Twig_Environment($loader);
118
+ $twig->addGlobal('text', new Text());
119
+
120
+ You can then use the ``text`` variable anywhere in a template:
121
+
122
+ .. code-block:: jinja
123
+
124
+ {{ text.lipsum(40) }}
125
+
126
+ Filters
127
+ -------
128
+
129
+ Creating a filter is as simple as associating a name with a PHP callable::
130
+
131
+ // an anonymous function
132
+ $filter = new Twig_SimpleFilter('rot13', function ($string) {
133
+ return str_rot13($string);
134
+ });
135
+
136
+ // or a simple PHP function
137
+ $filter = new Twig_SimpleFilter('rot13', 'str_rot13');
138
+
139
+ // or a class method
140
+ $filter = new Twig_SimpleFilter('rot13', array('SomeClass', 'rot13Filter'));
141
+
142
+ The first argument passed to the ``Twig_SimpleFilter`` constructor is the name
143
+ of the filter you will use in templates and the second one is the PHP callable
144
+ to associate with it.
145
+
146
+ Then, add the filter to your Twig environment::
147
+
148
+ $twig = new Twig_Environment($loader);
149
+ $twig->addFilter($filter);
150
+
151
+ And here is how to use it in a template:
152
+
153
+ .. code-block:: jinja
154
+
155
+ {{ 'Twig'|rot13 }}
156
+
157
+ {# will output Gjvt #}
158
+
159
+ When called by Twig, the PHP callable receives the left side of the filter
160
+ (before the pipe ``|``) as the first argument and the extra arguments passed
161
+ to the filter (within parentheses ``()``) as extra arguments.
162
+
163
+ For instance, the following code:
164
+
165
+ .. code-block:: jinja
166
+
167
+ {{ 'TWIG'|lower }}
168
+ {{ now|date('d/m/Y') }}
169
+
170
+ is compiled to something like the following::
171
+
172
+ <?php echo strtolower('TWIG') ?>
173
+ <?php echo twig_date_format_filter($now, 'd/m/Y') ?>
174
+
175
+ The ``Twig_SimpleFilter`` class takes an array of options as its last
176
+ argument::
177
+
178
+ $filter = new Twig_SimpleFilter('rot13', 'str_rot13', $options);
179
+
180
+ Environment aware Filters
181
+ ~~~~~~~~~~~~~~~~~~~~~~~~~
182
+
183
+ If you want to access the current environment instance in your filter, set the
184
+ ``needs_environment`` option to ``true``; Twig will pass the current
185
+ environment as the first argument to the filter call::
186
+
187
+ $filter = new Twig_SimpleFilter('rot13', function (Twig_Environment $env, $string) {
188
+ // get the current charset for instance
189
+ $charset = $env->getCharset();
190
+
191
+ return str_rot13($string);
192
+ }, array('needs_environment' => true));
193
+
194
+ Context aware Filters
195
+ ~~~~~~~~~~~~~~~~~~~~~
196
+
197
+ If you want to access the current context in your filter, set the
198
+ ``needs_context`` option to ``true``; Twig will pass the current context as
199
+ the first argument to the filter call (or the second one if
200
+ ``needs_environment`` is also set to ``true``)::
201
+
202
+ $filter = new Twig_SimpleFilter('rot13', function ($context, $string) {
203
+ // ...
204
+ }, array('needs_context' => true));
205
+
206
+ $filter = new Twig_SimpleFilter('rot13', function (Twig_Environment $env, $context, $string) {
207
+ // ...
208
+ }, array('needs_context' => true, 'needs_environment' => true));
209
+
210
+ Automatic Escaping
211
+ ~~~~~~~~~~~~~~~~~~
212
+
213
+ If automatic escaping is enabled, the output of the filter may be escaped
214
+ before printing. If your filter acts as an escaper (or explicitly outputs html
215
+ or JavaScript code), you will want the raw output to be printed. In such a
216
+ case, set the ``is_safe`` option::
217
+
218
+ $filter = new Twig_SimpleFilter('nl2br', 'nl2br', array('is_safe' => array('html')));
219
+
220
+ Some filters may need to work on input that is already escaped or safe, for
221
+ example when adding (safe) html tags to originally unsafe output. In such a
222
+ case, set the ``pre_escape`` option to escape the input data before it is run
223
+ through your filter::
224
+
225
+ $filter = new Twig_SimpleFilter('somefilter', 'somefilter', array('pre_escape' => 'html', 'is_safe' => array('html')));
226
+
227
+ Dynamic Filters
228
+ ~~~~~~~~~~~~~~~
229
+
230
+ A filter name containing the special ``*`` character is a dynamic filter as
231
+ the ``*`` can be any string::
232
+
233
+ $filter = new Twig_SimpleFilter('*_path', function ($name, $arguments) {
234
+ // ...
235
+ });
236
+
237
+ The following filters will be matched by the above defined dynamic filter:
238
+
239
+ * ``product_path``
240
+ * ``category_path``
241
+
242
+ A dynamic filter can define more than one dynamic parts::
243
+
244
+ $filter = new Twig_SimpleFilter('*_path', function ($name, $suffix, $arguments) {
245
+ // ...
246
+ });
247
+
248
+ The filter will receive all dynamic part values before the normal filters
249
+ arguments, but after the environment and the context. For instance, a call to
250
+ ``'foo'|a_path_b()`` will result in the following arguments to be passed to
251
+ the filter: ``('a', 'b', 'foo')``.
252
+
253
+ Functions
254
+ ---------
255
+
256
+ Functions are defined in the exact same way as filters, but you need to create
257
+ an instance of ``Twig_SimpleFunction``::
258
+
259
+ $twig = new Twig_Environment($loader);
260
+ $function = new Twig_SimpleFunction('function_name', function () {
261
+ // ...
262
+ });
263
+ $twig->addFunction($function);
264
+
265
+ Functions support the same features as filters, except for the ``pre_escape``
266
+ and ``preserves_safety`` options.
267
+
268
+ Tests
269
+ -----
270
+
271
+ Tests are defined in the exact same way as filters and functions, but you need
272
+ to create an instance of ``Twig_SimpleTest``::
273
+
274
+ $twig = new Twig_Environment($loader);
275
+ $test = new Twig_SimpleTest('test_name', function () {
276
+ // ...
277
+ });
278
+ $twig->addTest($test);
279
+
280
+ Tests do not support any options.
281
+
282
+ Tags
283
+ ----
284
+
285
+ One of the most exciting feature of a template engine like Twig is the
286
+ possibility to define new language constructs. This is also the most complex
287
+ feature as you need to understand how Twig's internals work.
288
+
289
+ Let's create a simple ``set`` tag that allows the definition of simple
290
+ variables from within a template. The tag can be used like follows:
291
+
292
+ .. code-block:: jinja
293
+
294
+ {% set name = "value" %}
295
+
296
+ {{ name }}
297
+
298
+ {# should output value #}
299
+
300
+ .. note::
301
+
302
+ The ``set`` tag is part of the Core extension and as such is always
303
+ available. The built-in version is slightly more powerful and supports
304
+ multiple assignments by default (cf. the template designers chapter for
305
+ more information).
306
+
307
+ Three steps are needed to define a new tag:
308
+
309
+ * Defining a Token Parser class (responsible for parsing the template code);
310
+
311
+ * Defining a Node class (responsible for converting the parsed code to PHP);
312
+
313
+ * Registering the tag.
314
+
315
+ Registering a new tag
316
+ ~~~~~~~~~~~~~~~~~~~~~
317
+
318
+ Adding a tag is as simple as calling the ``addTokenParser`` method on the
319
+ ``Twig_Environment`` instance::
320
+
321
+ $twig = new Twig_Environment($loader);
322
+ $twig->addTokenParser(new Project_Set_TokenParser());
323
+
324
+ Defining a Token Parser
325
+ ~~~~~~~~~~~~~~~~~~~~~~~
326
+
327
+ Now, let's see the actual code of this class::
328
+
329
+ class Project_Set_TokenParser extends Twig_TokenParser
330
+ {
331
+ public function parse(Twig_Token $token)
332
+ {
333
+ $lineno = $token->getLine();
334
+ $name = $this->parser->getStream()->expect(Twig_Token::NAME_TYPE)->getValue();
335
+ $this->parser->getStream()->expect(Twig_Token::OPERATOR_TYPE, '=');
336
+ $value = $this->parser->getExpressionParser()->parseExpression();
337
+
338
+ $this->parser->getStream()->expect(Twig_Token::BLOCK_END_TYPE);
339
+
340
+ return new Project_Set_Node($name, $value, $lineno, $this->getTag());
341
+ }
342
+
343
+ public function getTag()
344
+ {
345
+ return 'set';
346
+ }
347
+ }
348
+
349
+ The ``getTag()`` method must return the tag we want to parse, here ``set``.
350
+
351
+ The ``parse()`` method is invoked whenever the parser encounters a ``set``
352
+ tag. It should return a ``Twig_Node`` instance that represents the node (the
353
+ ``Project_Set_Node`` calls creating is explained in the next section).
354
+
355
+ The parsing process is simplified thanks to a bunch of methods you can call
356
+ from the token stream (``$this->parser->getStream()``):
357
+
358
+ * ``getCurrent()``: Gets the current token in the stream.
359
+
360
+ * ``next()``: Moves to the next token in the stream, *but returns the old one*.
361
+
362
+ * ``test($type)``, ``test($value)`` or ``test($type, $value)``: Determines whether
363
+ the current token is of a particular type or value (or both). The value may be an
364
+ array of several possible values.
365
+
366
+ * ``expect($type[, $value[, $message]])``: If the current token isn't of the given
367
+ type/value a syntax error is thrown. Otherwise, if the type and value are correct,
368
+ the token is returned and the stream moves to the next token.
369
+
370
+ * ``look()``: Looks a the next token without consuming it.
371
+
372
+ Parsing expressions is done by calling the ``parseExpression()`` like we did for
373
+ the ``set`` tag.
374
+
375
+ .. tip::
376
+
377
+ Reading the existing ``TokenParser`` classes is the best way to learn all
378
+ the nitty-gritty details of the parsing process.
379
+
380
+ Defining a Node
381
+ ~~~~~~~~~~~~~~~
382
+
383
+ The ``Project_Set_Node`` class itself is rather simple::
384
+
385
+ class Project_Set_Node extends Twig_Node
386
+ {
387
+ public function __construct($name, Twig_Node_Expression $value, $lineno, $tag = null)
388
+ {
389
+ parent::__construct(array('value' => $value), array('name' => $name), $lineno, $tag);
390
+ }
391
+
392
+ public function compile(Twig_Compiler $compiler)
393
+ {
394
+ $compiler
395
+ ->addDebugInfo($this)
396
+ ->write('$context[\''.$this->getAttribute('name').'\'] = ')
397
+ ->subcompile($this->getNode('value'))
398
+ ->raw(";\n")
399
+ ;
400
+ }
401
+ }
402
+
403
+ The compiler implements a fluid interface and provides methods that helps the
404
+ developer generate beautiful and readable PHP code:
405
+
406
+ * ``subcompile()``: Compiles a node.
407
+
408
+ * ``raw()``: Writes the given string as is.
409
+
410
+ * ``write()``: Writes the given string by adding indentation at the beginning
411
+ of each line.
412
+
413
+ * ``string()``: Writes a quoted string.
414
+
415
+ * ``repr()``: Writes a PHP representation of a given value (see
416
+ ``Twig_Node_For`` for a usage example).
417
+
418
+ * ``addDebugInfo()``: Adds the line of the original template file related to
419
+ the current node as a comment.
420
+
421
+ * ``indent()``: Indents the generated code (see ``Twig_Node_Block`` for a
422
+ usage example).
423
+
424
+ * ``outdent()``: Outdents the generated code (see ``Twig_Node_Block`` for a
425
+ usage example).

429
+ Creating an Extension
430
+ ---------------------
431
+
432
+ The main motivation for writing an extension is to move often used code into a
433
+ reusable class like adding support for internationalization. An extension can
434
+ define tags, filters, tests, operators, global variables, functions, and node
435
+ visitors.
436
+
437
+ Creating an extension also makes for a better separation of code that is
438
+ executed at compilation time and code needed at runtime. As such, it makes
439
+ your code faster.
440
+
441
+ Most of the time, it is useful to create a single extension for your project,
442
+ to host all the specific tags and filters you want to add to Twig.
443
+
444
+ .. tip::
445
+
446
+ When packaging your code into an extension, Twig is smart enough to
447
+ recompile your templates whenever you make a change to it (when
448
+ ``auto_reload`` is enabled).
449
+
450
+ .. note::
451
+
452
+ Before writing your own extensions, have a look at the Twig official
453
+ extension repository: http://github.com/fabpot/Twig-extensions.
454
+
455
+ An extension is a class that implements the following interface::
456
+
457
+ interface Twig_ExtensionInterface
458
+ {
459
+ /**
460
+ * Initializes the runtime environment.
461
+ *
462
+ * This is where you can load some file that contains filter functions for instance.
463
+ *
464
+ * @param Twig_Environment $environment The current Twig_Environment instance
465
+ */
466
+ function initRuntime(Twig_Environment $environment);
467
+
468
+ /**
469
+ * Returns the token parser instances to add to the existing list.
470
+ *
471
+ * @return array An array of Twig_TokenParserInterface or Twig_TokenParserBrokerInterface instances
472
+ */
473
+ function getTokenParsers();
474
+
475
+ /**
476
+ * Returns the node visitor instances to add to the existing list.
477
+ *
478
+ * @return array An array of Twig_NodeVisitorInterface instances
479
+ */
480
+ function getNodeVisitors();
481
+
482
+ /**
483
+ * Returns a list of filters to add to the existing list.
484
+ *
485
+ * @return array An array of filters
486
+ */
487
+ function getFilters();
488
+
489
+ /**
490
+ * Returns a list of tests to add to the existing list.
491
+ *
492
+ * @return array An array of tests
493
+ */
494
+ function getTests();
495
+
496
+ /**
497
+ * Returns a list of functions to add to the existing list.
498
+ *
499
+ * @return array An array of functions
500
+ */
501
+ function getFunctions();
502
+
503
+ /**
504
+ * Returns a list of operators to add to the existing list.
505
+ *
506
+ * @return array An array of operators
507
+ */
508
+ function getOperators();
509
+
510
+ /**
511
+ * Returns a list of global variables to add to the existing list.
512
+ *
513
+ * @return array An array of global variables
514
+ */
515
+ function getGlobals();
516
+
517
+ /**
518
+ * Returns the name of the extension.
519
+ *
520
+ * @return string The extension name
521
+ */
522
+ function getName();
523
+ }
524
+
525
+ To keep your extension class clean and lean, it can inherit from the built-in
526
+ ``Twig_Extension`` class instead of implementing the whole interface. That
527
+ way, you just need to implement the ``getName()`` method as the
528
+ ``Twig_Extension`` provides empty implementations for all other methods.
529
+
530
+ The ``getName()`` method must return a unique identifier for your extension.
531
+
532
+ Now, with this information in mind, let's create the most basic extension
533
+ possible::
534
+
535
+ class Project_Twig_Extension extends Twig_Extension
536
+ {
537
+ public function getName()
538
+ {
539
+ return 'project';
540
+ }
541
+ }
542
+
543
+ .. note::
544
+
545
+ Of course, this extension does nothing for now. We will customize it in
546
+ the next sections.
547
+
548
+ Twig does not care where you save your extension on the filesystem, as all
549
+ extensions must be registered explicitly to be available in your templates.
550
+
551
+ You can register an extension by using the ``addExtension()`` method on your
552
+ main ``Environment`` object::
553
+
554
+ $twig = new Twig_Environment($loader);
555
+ $twig->addExtension(new Project_Twig_Extension());
556
+
557
+ Of course, you need to first load the extension file by either using
558
+ ``require_once()`` or by using an autoloader (see `spl_autoload_register()`_).
559
+
560
+ .. tip::
561
+
562
+ The bundled extensions are great examples of how extensions work.
563
+
564
+ Globals
565
+ ~~~~~~~
566
+
567
+ Global variables can be registered in an extension via the ``getGlobals()``
568
+ method::
569
+
570
+ class Project_Twig_Extension extends Twig_Extension
571
+ {
572
+ public function getGlobals()
573
+ {
574
+ return array(
575
+ 'text' => new Text(),
576
+ );
577
+ }
578
+
579
+ // ...
580
+ }
581
+
582
+ Functions
583
+ ~~~~~~~~~
584
+
585
+ Functions can be registered in an extension via the ``getFunctions()``
586
+ method::
587
+
588
+ class Project_Twig_Extension extends Twig_Extension
589
+ {
590
+ public function getFunctions()
591
+ {
592
+ return array(
593
+ new Twig_SimpleFunction('lipsum', 'generate_lipsum'),
594
+ );
595
+ }
596
+
597
+ // ...
598
+ }
599
+
600
+ Filters
601
+ ~~~~~~~
602
+
603
+ To add a filter to an extension, you need to override the ``getFilters()``
604
+ method. This method must return an array of filters to add to the Twig
605
+ environment::
606
+
607
+ class Project_Twig_Extension extends Twig_Extension
608
+ {
609
+ public function getFilters()
610
+ {
611
+ return array(
612
+ new Twig_SimpleFilter('rot13', 'str_rot13'),
613
+ );
614
+ }
615
+
616
+ // ...
617
+ }
618
+
619
+ Tags
620
+ ~~~~
621
+
622
+ Adding a tag in an extension can be done by overriding the
623
+ ``getTokenParsers()`` method. This method must return an array of tags to add
624
+ to the Twig environment::
625
+
626
+ class Project_Twig_Extension extends Twig_Extension
627
+ {
628
+ public function getTokenParsers()
629
+ {
630
+ return array(new Project_Set_TokenParser());
631
+ }
632
+
633
+ // ...
634
+ }
635
+
636
+ In the above code, we have added a single new tag, defined by the
637
+ ``Project_Set_TokenParser`` class. The ``Project_Set_TokenParser`` class is
638
+ responsible for parsing the tag and compiling it to PHP.
639
+
640
+ Operators
641
+ ~~~~~~~~~
642
+
643
+ The ``getOperators()`` methods allows to add new operators. Here is how to add
644
+ ``!``, ``||``, and ``&&`` operators::
645
+
646
+ class Project_Twig_Extension extends Twig_Extension
647
+ {
648
+ public function getOperators()
649
+ {
650
+ return array(
651
+ array(
652
+ '!' => array('precedence' => 50, 'class' => 'Twig_Node_Expression_Unary_Not'),
653
+ ),
654
+ array(
655
+ '||' => array('precedence' => 10, 'class' => 'Twig_Node_Expression_Binary_Or', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
656
+ '&&' => array('precedence' => 15, 'class' => 'Twig_Node_Expression_Binary_And', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
657
+ ),
658
+ );
659
+ }
660
+
661
+ // ...
662
+ }
663
+
664
+ Tests
665
+ ~~~~~
666
+
667
+ The ``getTests()`` methods allows to add new test functions::
668
+
669
+ class Project_Twig_Extension extends Twig_Extension
670
+ {
671
+ public function getTests()
672
+ {
673
+ return array(
674
+ new Twig_SimpleTest('even', 'twig_test_even'),
675
+ );
676
+ }
677
+
678
+ // ...
679
+ }
680
+
681
+ Overloading
682
+ -----------
683
+
684
+ To overload an already defined filter, test, operator, global variable, or
685
+ function, define it again **as late as possible**::
686
+
687
+ $twig = new Twig_Environment($loader);
688
+ $twig->addFilter(new Twig_SimpleFilter('date', function ($timestamp, $format = 'F j, Y H:i') {
689
+ // do something different from the built-in date filter
690
+ }));
691
+
692
+ Here, we have overloaded the built-in ``date`` filter with a custom one.
693
+
694
+ That also works with an extension::
695
+
696
+ class MyCoreExtension extends Twig_Extension
697
+ {
698
+ public function getFilters()
699
+ {
700
+ return array(
701
+ new Twig_SimpleFilter('date', array($this, 'dateFilter')),
702
+ );
703
+ }
704
+
705
+ public function dateFilter($timestamp, $format = 'F j, Y H:i')
706
+ {
707
+ // do something different from the built-in date filter
708
+ }
709
+
710
+ public function getName()
711
+ {
712
+ return 'project';
713
+ }
714
+ }
715
+
716
+ $twig = new Twig_Environment($loader);
717
+ $twig->addExtension(new MyCoreExtension());
718
+
719
+ .. caution::
720
+
721
+ Note that overloading the built-in Twig elements is not recommended as it
722
+ might be confusing.
723
+
724
+ Testing an Extension
725
+ --------------------
726
+
727
+ Functional Tests
728
+ ~~~~~~~~~~~~~~~~
729
+
730
+ You can create functional tests for extensions simply by creating the
731
+ following file structure in your test directory::
732
+
733
+ Fixtures/
734
+ filters/
735
+ foo.test
736
+ bar.test
737
+ functions/
738
+ foo.test
739
+ bar.test
740
+ tags/
741
+ foo.test
742
+ bar.test
743
+ IntegrationTest.php
744
+
745
+ The ``IntegrationTest.php`` file should look like this::
746
+
747
+ class Project_Tests_IntegrationTest extends Twig_Test_IntegrationTestCase
748
+ {
749
+ public function getExtensions()
750
+ {
751
+ return array(
752
+ new Project_Twig_Extension1(),
753
+ new Project_Twig_Extension2(),
754
+ );
755
+ }
756
+
757
+ public function getFixturesDir()
758
+ {
759
+ return dirname(__FILE__).'/Fixtures/';
760
+ }
761
+ }
762
+
763
+ Fixtures examples can be found within the Twig repository
764
+ `tests/Twig/Fixtures`_ directory.
765
+
766
+ Node Tests
767
+ ~~~~~~~~~~
768
+
769
+ Testing the node visitors can be complex, so extend your test cases from
770
+ ``Twig_Test_NodeTestCase``. Examples can be found in the Twig repository
771
+ `tests/Twig/Node`_ directory.

1
+ Extending Twig
2
+ ==============
3
+
4
+ .. caution::
5
+
6
+ This section describes how to extends Twig for versions **older than
7
+ 1.12**. If you are using a newer version, read the :doc:`newer<advanced>`
8
+ chapter instead.
9
+
10
+ Twig can be extended in many ways; you can add extra tags, filters, tests,
11
+ operators, global variables, and functions. You can even extend the parser
12
+ itself with node visitors.
13
+
14
+ .. note::
15
+
16
+ The first section of this chapter describes how to extend Twig easily. If
17
+ you want to reuse your changes in different projects or if you want to
18
+ share them with others, you should then create an extension as described
19
+ in the following section.
20
+
21
+ .. caution::
22
+
23
+ When extending Twig by calling methods on the Twig environment instance,
24
+ Twig won't be able to recompile your templates when the PHP code is
25
+ updated. To see your changes in real-time, either disable template caching
26
+ or package your code into an extension (see the next section of this
27
+ chapter).
28
+
29
+ Before extending Twig, you must understand the differences between all the
30
+ different possible extension points and when to use them.
31
+
32
+ First, remember that Twig has two main language constructs:
33
+
34
+ * ``{{ }}``: used to print the result of an expression evaluation;
35
+
36
+ * ``{% %}``: used to execute statements.
37
+
38
+ To understand why Twig exposes so many extension points, let's see how to
39
+ implement a *Lorem ipsum* generator (it needs to know the number of words to
40
+ generate).
41
+
42
+ You can use a ``lipsum`` *tag*:
43
+
44
+ .. code-block:: jinja
45
+
46
+ {% lipsum 40 %}
47
+
48
+ That works, but using a tag for ``lipsum`` is not a good idea for at least
49
+ three main reasons:
50
+
51
+ * ``lipsum`` is not a language construct;
52
+ * The tag outputs something;
53
+ * The tag is not flexible as you cannot use it in an expression:
54
+
55
+ .. code-block:: jinja
56
+
57
+ {{ 'some text' ~ {% lipsum 40 %} ~ 'some more text' }}
58
+
59
+ In fact, you rarely need to create tags; and that's good news because tags are
60
+ the most complex extension point of Twig.
61
+
62
+ Now, let's use a ``lipsum`` *filter*:
63
+
64
+ .. code-block:: jinja
65
+
66
+ {{ 40|lipsum }}
67
+
68
+ Again, it works, but it looks weird. A filter transforms the passed value to
69
+ something else but here we use the value to indicate the number of words to
70
+ generate (so, ``40`` is an argument of the filter, not the value we want to
71
+ transform).
72
+
73
+ Next, let's use a ``lipsum`` *function*:
74
+
75
+ .. code-block:: jinja
76
+
77
+ {{ lipsum(40) }}
78
+
79
+ Here we go. For this specific example, the creation of a function is the
80
+ extension point to use. And you can use it anywhere an expression is accepted:
81
+
82
+ .. code-block:: jinja
83
+
84
+ {{ 'some text' ~ ipsum(40) ~ 'some more text' }}
85
+
86
+ {% set ipsum = ipsum(40) %}
87
+
88
+ Last but not the least, you can also use a *global* object with a method able
89
+ to generate lorem ipsum text:
90
+
91
+ .. code-block:: jinja
92
+
93
+ {{ text.lipsum(40) }}
94
+
95
+ As a rule of thumb, use functions for frequently used features and global
96
+ objects for everything else.
97
+
98
+ Keep in mind the following when you want to extend Twig:

+
100

101
+ What? Implementation difficulty? How often? When?
102
+ ========== ========================== ========== =========================
103

108
+ *test* trivial rare Boolean decision
109
+ *operator* trivial rare Values transformation
110
+ ========== ========================== ========== =========================
111
+
112
+ Globals
113
+ -------
114
+
115
+ A global variable is like any other template variable, except that it's
116
+ available in all templates and macros::
117
+
118
+ $twig = new Twig_Environment($loader);
119
+ $twig->addGlobal('text', new Text());
120
+
121
+ You can then use the ``text`` variable anywhere in a template:
122
+
123
+ .. code-block:: jinja
124
+
125
+ {{ text.lipsum(40) }}
126
+
127
+ Filters
128
+ -------
129
+
130
+ A filter is a regular PHP function or an object method that takes the left
131
+ side of the filter (before the pipe ``|``) as first argument and the extra
132
+ arguments passed to the filter (within parentheses ``()``) as extra arguments.
133
+
134
+ Defining a filter is as easy as associating the filter name with a PHP
135
+ callable. For instance, let's say you have the following code in a template:
136
+
137
+ .. code-block:: jinja
138
+
139
+ {{ 'TWIG'|lower }}
140
+
141
+ When compiling this template to PHP, Twig looks for the PHP callable
142
+ associated with the ``lower`` filter. The ``lower`` filter is a built-in Twig
143
+ filter, and it is simply mapped to the PHP ``strtolower()`` function. After
144
+ compilation, the generated PHP code is roughly equivalent to:
145
+
146
+ .. code-block:: html+php
147
+
148
+ <?php echo strtolower('TWIG') ?>
149
+
150
+ As you can see, the ``'TWIG'`` string is passed as a first argument to the PHP
151
+ function.
152
+
153
+ A filter can also take extra arguments like in the following example:
154
+
155
+ .. code-block:: jinja
156
+
157
+ {{ now|date('d/m/Y') }}
158
+
159
+ In this case, the extra arguments are passed to the function after the main
160
+ argument, and the compiled code is equivalent to:
161
+
162
+ .. code-block:: html+php
163
+
164
+ <?php echo twig_date_format_filter($now, 'd/m/Y') ?>
165
+
166
+ Let's see how to create a new filter.
167
+
168
+ In this section, we will create a ``rot13`` filter, which should return the
169
+ `rot13`_ transformation of a string. Here is an example of its usage and the
170
+ expected output:
171
+
172
+ .. code-block:: jinja
173
+
174
+ {{ "Twig"|rot13 }}
175
+
176
+ {# should displays Gjvt #}
177
+
178
+ Adding a filter is as simple as calling the ``addFilter()`` method on the
179
+ ``Twig_Environment`` instance::
180
+
181
+ $twig = new Twig_Environment($loader);
182
+ $twig->addFilter('rot13', new Twig_Filter_Function('str_rot13'));
183
+
184
+ The second argument of ``addFilter()`` is an instance of ``Twig_Filter``.
185
+ Here, we use ``Twig_Filter_Function`` as the filter is a PHP function. The
186
+ first argument passed to the ``Twig_Filter_Function`` constructor is the name
187
+ of the PHP function to call, here ``str_rot13``, a native PHP function.
188
+
189
+ Let's say I now want to be able to add a prefix before the converted string:
190
+
191
+ .. code-block:: jinja
192
+
193
+ {{ "Twig"|rot13('prefix_') }}
194
+
195
+ {# should displays prefix_Gjvt #}
196
+
197
+ As the PHP ``str_rot13()`` function does not support this requirement, let's
198
+ create a new PHP function::
199
+
200
+ function project_compute_rot13($string, $prefix = '')
201
+ {
202
+ return $prefix.str_rot13($string);
203
+ }
204
+
205
+ As you can see, the ``prefix`` argument of the filter is passed as an extra
206
+ argument to the ``project_compute_rot13()`` function.
207
+
208
+ Adding this filter is as easy as before::
209
+
210
+ $twig->addFilter('rot13', new Twig_Filter_Function('project_compute_rot13'));
211
+
212
+ For better encapsulation, a filter can also be defined as a static method of a
213
+ class. The ``Twig_Filter_Function`` class can also be used to register such
214
+ static methods as filters::
215
+
216
+ $twig->addFilter('rot13', new Twig_Filter_Function('SomeClass::rot13Filter'));
217
+
218
+ .. tip::
219
+
220
+ In an extension, you can also define a filter as a static method of the
221
+ extension class.
222
+
223
+ Environment aware Filters
224
+ ~~~~~~~~~~~~~~~~~~~~~~~~~
225
+
226
+ The ``Twig_Filter`` classes take options as their last argument. For instance,
227
+ if you want access to the current environment instance in your filter, set the
228
+ ``needs_environment`` option to ``true``::
229
+
230
+ $filter = new Twig_Filter_Function('str_rot13', array('needs_environment' => true));
231
+
232
+ Twig will then pass the current environment as the first argument to the
233
+ filter call::
234
+
235
+ function twig_compute_rot13(Twig_Environment $env, $string)
236
+ {
237
+ // get the current charset for instance
238
+ $charset = $env->getCharset();
239
+
240
+ return str_rot13($string);
241
+ }
242
+
243
+ Automatic Escaping
244
+ ~~~~~~~~~~~~~~~~~~
245
+
246
+ If automatic escaping is enabled, the output of the filter may be escaped
247
+ before printing. If your filter acts as an escaper (or explicitly outputs html
248
+ or javascript code), you will want the raw output to be printed. In such a
249
+ case, set the ``is_safe`` option::
250
+
251
+ $filter = new Twig_Filter_Function('nl2br', array('is_safe' => array('html')));
252
+
253
+ Some filters may need to work on input that is already escaped or safe, for
254
+ example when adding (safe) html tags to originally unsafe output. In such a
255
+ case, set the ``pre_escape`` option to escape the input data before it is run
256
+ through your filter::
257
+
258
+ $filter = new Twig_Filter_Function('somefilter', array('pre_escape' => 'html', 'is_safe' => array('html')));
259
+
260
+ Dynamic Filters
261
+ ~~~~~~~~~~~~~~~
262
+
263
+ .. versionadded:: 1.5
264
+ Dynamic filters support was added in Twig 1.5.
265
+
266
+ A filter name containing the special ``*`` character is a dynamic filter as
267
+ the ``*`` can be any string::
268
+
269
+ $twig->addFilter('*_path', new Twig_Filter_Function('twig_path'));
270
+
271
+ function twig_path($name, $arguments)
272
+ {
273
+ // ...
274
+ }
275
+
276
+ The following filters will be matched by the above defined dynamic filter:
277
+
278
+ * ``product_path``
279
+ * ``category_path``
280
+
281
+ A dynamic filter can define more than one dynamic parts::
282
+
283
+ $twig->addFilter('*_path_*', new Twig_Filter_Function('twig_path'));
284
+
285
+ function twig_path($name, $suffix, $arguments)
286
+ {
287
+ // ...
288
+ }
289
+
290
+ The filter will receive all dynamic part values before the normal filters
291
+ arguments. For instance, a call to ``'foo'|a_path_b()`` will result in the
292
+ following PHP call: ``twig_path('a', 'b', 'foo')``.
293
+
294
+ Functions
295
+ ---------
296
+
297
+ A function is a regular PHP function or an object method that can be called from
298
+ templates.
299
+
300
+ .. code-block:: jinja
301
+
302
+ {{ constant("DATE_W3C") }}
303
+
304
+ When compiling this template to PHP, Twig looks for the PHP callable
305
+ associated with the ``constant`` function. The ``constant`` function is a built-in Twig
306
+ function, and it is simply mapped to the PHP ``constant()`` function. After
307
+ compilation, the generated PHP code is roughly equivalent to:
308
+
309
+ .. code-block:: html+php
310
+
311
+ <?php echo constant('DATE_W3C') ?>
312
+
313
+ Adding a function is similar to adding a filter. This can be done by calling the
314
+ ``addFunction()`` method on the ``Twig_Environment`` instance::
315
+
316
+ $twig = new Twig_Environment($loader);
317
+ $twig->addFunction('functionName', new Twig_Function_Function('someFunction'));
318
+
319
+ You can also expose extension methods as functions in your templates::
320
+
321
+ // $this is an object that implements Twig_ExtensionInterface.
322
+ $twig = new Twig_Environment($loader);
323
+ $twig->addFunction('otherFunction', new Twig_Function_Method($this, 'someMethod'));
324
+
325
+ Functions also support ``needs_environment`` and ``is_safe`` parameters.
326
+
327
+ Dynamic Functions
328
+ ~~~~~~~~~~~~~~~~~
329
+
330
+ .. versionadded:: 1.5
331
+ Dynamic functions support was added in Twig 1.5.
332
+
333
+ A function name containing the special ``*`` character is a dynamic function
334
+ as the ``*`` can be any string::
335
+
336
+ $twig->addFunction('*_path', new Twig_Function_Function('twig_path'));
337
+
338
+ function twig_path($name, $arguments)
339
+ {
340
+ // ...
341
+ }
342
+
343
+ The following functions will be matched by the above defined dynamic function:
344
+
345
+ * ``product_path``
346
+ * ``category_path``
347
+
348
+ A dynamic function can define more than one dynamic parts::
349
+
350
+ $twig->addFilter('*_path_*', new Twig_Filter_Function('twig_path'));
351
+
352
+ function twig_path($name, $suffix, $arguments)
353
+ {
354
+ // ...
355
+ }
356
+
357
+ The function will receive all dynamic part values before the normal functions
358
+ arguments. For instance, a call to ``a_path_b('foo')`` will result in the
359
+ following PHP call: ``twig_path('a', 'b', 'foo')``.
360
+
361
+ Tags
362
+ ----
363
+
364
+ One of the most exciting feature of a template engine like Twig is the
365
+ possibility to define new language constructs. This is also the most complex
366
+ feature as you need to understand how Twig's internals work.
367
+
368
+ Let's create a simple ``set`` tag that allows the definition of simple
369
+ variables from within a template. The tag can be used like follows:
370
+
371
+ .. code-block:: jinja
372
+
373
+ {% set name = "value" %}
374
+
375
+ {{ name }}
376
+
377
+ {# should output value #}
378
+
379
+ .. note::
380
+
381
+ The ``set`` tag is part of the Core extension and as such is always
382
+ available. The built-in version is slightly more powerful and supports
383
+ multiple assignments by default (cf. the template designers chapter for
384
+ more information).
385
+
386
+ Three steps are needed to define a new tag:
387
+
388
+ * Defining a Token Parser class (responsible for parsing the template code);
389
+
390
+ * Defining a Node class (responsible for converting the parsed code to PHP);
391
+
392
+ * Registering the tag.
393
+
394
+ Registering a new tag
395
+ ~~~~~~~~~~~~~~~~~~~~~
396
+
397
+ Adding a tag is as simple as calling the ``addTokenParser`` method on the
398
+ ``Twig_Environment`` instance::
399
+
400
+ $twig = new Twig_Environment($loader);
401
+ $twig->addTokenParser(new Project_Set_TokenParser());
402
+
403
+ Defining a Token Parser
404
+ ~~~~~~~~~~~~~~~~~~~~~~~
405
+
406
+ Now, let's see the actual code of this class::
407
+
408
+ class Project_Set_TokenParser extends Twig_TokenParser
409
+ {
410
+ public function parse(Twig_Token $token)
411
+ {
412
+ $lineno = $token->getLine();
413
+ $name = $this->parser->getStream()->expect(Twig_Token::NAME_TYPE)->getValue();
414
+ $this->parser->getStream()->expect(Twig_Token::OPERATOR_TYPE, '=');
415
+ $value = $this->parser->getExpressionParser()->parseExpression();
416
+
417
+ $this->parser->getStream()->expect(Twig_Token::BLOCK_END_TYPE);
418
+
419
+ return new Project_Set_Node($name, $value, $lineno, $this->getTag());
420
+ }
421
+
422
+ public function getTag()
423
+ {
424
+ return 'set';
425
+ }
426
+ }
427
+
428
+ The ``getTag()`` method must return the tag we want to parse, here ``set``.
429
+
430
+ The ``parse()`` method is invoked whenever the parser encounters a ``set``
431
+ tag. It should return a ``Twig_Node`` instance that represents the node (the
432
+ ``Project_Set_Node`` calls creating is explained in the next section).
433
+
434
+ The parsing process is simplified thanks to a bunch of methods you can call
435
+ from the token stream (``$this->parser->getStream()``):
436
+
437
+ * ``getCurrent()``: Gets the current token in the stream.
438
+
439
+ * ``next()``: Moves to the next token in the stream, *but returns the old one*.
440
+
441
+ * ``test($type)``, ``test($value)`` or ``test($type, $value)``: Determines whether
442
+ the current token is of a particular type or value (or both). The value may be an
443
+ array of several possible values.
444
+
445
+ * ``expect($type[, $value[, $message]])``: If the current token isn't of the given
446
+ type/value a syntax error is thrown. Otherwise, if the type and value are correct,
447
+ the token is returned and the stream moves to the next token.
448
+
449
+ * ``look()``: Looks a the next token without consuming it.
450
+
451
+ Parsing expressions is done by calling the ``parseExpression()`` like we did for
452
+ the ``set`` tag.
453
+
454
+ .. tip::
455
+
456
+ Reading the existing ``TokenParser`` classes is the best way to learn all
457
+ the nitty-gritty details of the parsing process.
458
+
459
+ Defining a Node
460
+ ~~~~~~~~~~~~~~~
461
+
462
+ The ``Project_Set_Node`` class itself is rather simple::
463
+
464
+ class Project_Set_Node extends Twig_Node
465
+ {
466
+ public function __construct($name, Twig_Node_Expression $value, $lineno, $tag = null)
467
+ {
468
+ parent::__construct(array('value' => $value), array('name' => $name), $lineno, $tag);
469
+ }
470
+
471
+ public function compile(Twig_Compiler $compiler)
472
+ {
473
+ $compiler
474
+ ->addDebugInfo($this)
475
+ ->write('$context[\''.$this->getAttribute('name').'\'] = ')
476
+ ->subcompile($this->getNode('value'))
477
+ ->raw(";\n")
478
+ ;
479
+ }
480
+ }
481
+
482
+ The compiler implements a fluid interface and provides methods that helps the
483
+ developer generate beautiful and readable PHP code:
484
+
485
+ * ``subcompile()``: Compiles a node.
486
+
487
+ * ``raw()``: Writes the given string as is.
488
+
489
+ * ``write()``: Writes the given string by adding indentation at the beginning
490
+ of each line.
491
+
492
+ * ``string()``: Writes a quoted string.
493
+
494
+ * ``repr()``: Writes a PHP representation of a given value (see
495
+ ``Twig_Node_For`` for a usage example).
496
+
497
+ * ``addDebugInfo()``: Adds the line of the original template file related to
498
+ the current node as a comment.
499
+
500
+ * ``indent()``: Indents the generated code (see ``Twig_Node_Block`` for a
501
+ usage example).
502
+
503
+ * ``outdent()``: Outdents the generated code (see ``Twig_Node_Block`` for a
504
+ usage example).

+
508
+ Creating an Extension
509
+ ---------------------
510
+
511
+ The main motivation for writing an extension is to move often used code into a
512
+ reusable class like adding support for internationalization. An extension can
513
+ define tags, filters, tests, operators, global variables, functions, and node
514
+ visitors.
515
+
516
+ Creating an extension also makes for a better separation of code that is
517
+ executed at compilation time and code needed at runtime. As such, it makes
518
+ your code faster.
519
+
520
+ Most of the time, it is useful to create a single extension for your project,
521
+ to host all the specific tags and filters you want to add to Twig.
522
+
523
+ .. tip::
524
+
525
+ When packaging your code into an extension, Twig is smart enough to
526
+ recompile your templates whenever you make a change to it (when the
527
+ ``auto_reload`` is enabled).
528
+
529
+ .. note::
530
+
531
+ Before writing your own extensions, have a look at the Twig official
532
+ extension repository: http://github.com/fabpot/Twig-extensions.
533
+
534
+ An extension is a class that implements the following interface::
535
+
536
+ interface Twig_ExtensionInterface
537
+ {
538
+ /**
539
+ * Initializes the runtime environment.
540
+ *
541
+ * This is where you can load some file that contains filter functions for instance.
542
+ *
543
+ * @param Twig_Environment $environment The current Twig_Environment instance
544
+ */
545
+ function initRuntime(Twig_Environment $environment);
546
+
547
+ /**

+ * Returns the token parser instances to add to the existing list.
549

551

552

604
+ To keep your extension class clean and lean, it can inherit from the built-in
605
+ ``Twig_Extension`` class instead of implementing the whole interface. That
606
+ way, you just need to implement the ``getName()`` method as the
607
+ ``Twig_Extension`` provides empty implementations for all other methods.
608
+
609
+ The ``getName()`` method must return a unique identifier for your extension.
610
+
611
+ Now, with this information in mind, let's create the most basic extension
612
+ possible::
613
+
614
+ class Project_Twig_Extension extends Twig_Extension
615
+ {
616
+ public function getName()
617
+ {
618
+ return 'project';
619
+ }
620
+ }
621
+
622
+ .. note::
623
+
624
+ Of course, this extension does nothing for now. We will customize it in
625
+ the next sections.
626
+
627
+ Twig does not care where you save your extension on the filesystem, as all
628
+ extensions must be registered explicitly to be available in your templates.
629
+
630
+ You can register an extension by using the ``addExtension()`` method on your
631
+ main ``Environment`` object::
632
+
633
+ $twig = new Twig_Environment($loader);
634
+ $twig->addExtension(new Project_Twig_Extension());
635
+
636
+ Of course, you need to first load the extension file by either using
637
+ ``require_once()`` or by using an autoloader (see `spl_autoload_register()`_).
638
+
639
+ .. tip::
640
+
641
+ The bundled extensions are great examples of how extensions work.
642
+
643
+ Globals
644
+ ~~~~~~~
645
+
646
+ Global variables can be registered in an extension via the ``getGlobals()``
647
+ method::
648
+
649
+ class Project_Twig_Extension extends Twig_Extension
650
+ {
651
+ public function getGlobals()
652
+ {
653
+ return array(
654
+ 'text' => new Text(),
655
+ );
656
+ }
657
+
658
+ // ...
659
+ }
660
+
661
+ Functions
662
+ ~~~~~~~~~
663
+
664
+ Functions can be registered in an extension via the ``getFunctions()``
665
+ method::
666
+
667
+ class Project_Twig_Extension extends Twig_Extension
668
+ {
669
+ public function getFunctions()
670
+ {
671
+ return array(
672
+ 'lipsum' => new Twig_Function_Function('generate_lipsum'),
673
+ );
674
+ }
675
+
676
+ // ...
677
+ }
678
+
679
+ Filters
680
+ ~~~~~~~
681
+
682
+ To add a filter to an extension, you need to override the ``getFilters()``
683
+ method. This method must return an array of filters to add to the Twig
684
+ environment::
685
+
686
+ class Project_Twig_Extension extends Twig_Extension
687
+ {
688
+ public function getFilters()
689
+ {
690
+ return array(
691
+ 'rot13' => new Twig_Filter_Function('str_rot13'),
692
+ );
693
+ }
694
+
695
+ // ...
696
+ }
697
+
698
+ As you can see in the above code, the ``getFilters()`` method returns an array
699
+ where keys are the name of the filters (``rot13``) and the values the
700
+ definition of the filter (``new Twig_Filter_Function('str_rot13')``).
701
+
702
+ As seen in the previous chapter, you can also define filters as static methods
703
+ on the extension class::
704
+
705
+ $twig->addFilter('rot13', new Twig_Filter_Function('Project_Twig_Extension::rot13Filter'));
706
+
707
+ You can also use ``Twig_Filter_Method`` instead of ``Twig_Filter_Function``
708
+ when defining a filter to use a method::
709
+
710
+ class Project_Twig_Extension extends Twig_Extension
711
+ {
712
+ public function getFilters()
713
+ {
714
+ return array(
715
+ 'rot13' => new Twig_Filter_Method($this, 'rot13Filter'),
716
+ );
717
+ }
718
+
719
+ public function rot13Filter($string)
720
+ {
721
+ return str_rot13($string);
722
+ }
723
+
724
+ // ...
725
+ }
726
+
727
+ The first argument of the ``Twig_Filter_Method`` constructor is always
728
+ ``$this``, the current extension object. The second one is the name of the
729
+ method to call.
730
+
731
+ Using methods for filters is a great way to package your filter without
732
+ polluting the global namespace. This also gives the developer more flexibility
733
+ at the cost of a small overhead.
734
+
735
+ Overriding default Filters
736
+ ..........................
737
+
738
+ If some default core filters do not suit your needs, you can easily override
739
+ them by creating your own extension. Just use the same names as the one you
740
+ want to override::
741
+
742
+ class MyCoreExtension extends Twig_Extension
743
+ {
744
+ public function getFilters()
745
+ {
746
+ return array(
747
+ 'date' => new Twig_Filter_Method($this, 'dateFilter'),
748
+ // ...
749
+ );
750
+ }
751
+
752
+ public function dateFilter($timestamp, $format = 'F j, Y H:i')
753
+ {
754
+ return '...'.twig_date_format_filter($timestamp, $format);
755
+ }
756
+
757
+ public function getName()
758
+ {
759
+ return 'project';
760
+ }
761
+ }
762
+
763
+ Here, we override the ``date`` filter with a custom one. Using this extension
764
+ is as simple as registering the ``MyCoreExtension`` extension by calling the
765
+ ``addExtension()`` method on the environment instance::
766
+
767
+ $twig = new Twig_Environment($loader);
768
+ $twig->addExtension(new MyCoreExtension());
769
+
770
+ Tags
771
+ ~~~~
772
+
773
+ Adding a tag in an extension can be done by overriding the
774
+ ``getTokenParsers()`` method. This method must return an array of tags to add
775
+ to the Twig environment::
776
+
777
+ class Project_Twig_Extension extends Twig_Extension
778
+ {
779
+ public function getTokenParsers()
780
+ {
781
+ return array(new Project_Set_TokenParser());
782
+ }
783
+
784
+ // ...
785
+ }
786
+
787
+ In the above code, we have added a single new tag, defined by the
788
+ ``Project_Set_TokenParser`` class. The ``Project_Set_TokenParser`` class is
789
+ responsible for parsing the tag and compiling it to PHP.
790
+
791
+ Operators
792
+ ~~~~~~~~~
793
+
794
+ The ``getOperators()`` methods allows to add new operators. Here is how to add
795
+ ``!``, ``||``, and ``&&`` operators::
796
+
797
+ class Project_Twig_Extension extends Twig_Extension
798
+ {
799
+ public function getOperators()
800
+ {
801
+ return array(
802
+ array(
803
+ '!' => array('precedence' => 50, 'class' => 'Twig_Node_Expression_Unary_Not'),
804
+ ),
805
+ array(
806
+ '||' => array('precedence' => 10, 'class' => 'Twig_Node_Expression_Binary_Or', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
807
+ '&&' => array('precedence' => 15, 'class' => 'Twig_Node_Expression_Binary_And', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
808
+ ),
809
+ );
810
+ }
811
+
812
+ // ...
813
+ }
814
+
815
+ Tests
816
+ ~~~~~
817
+
818
+ The ``getTests()`` methods allows to add new test functions::
819
+
820
+ class Project_Twig_Extension extends Twig_Extension
821
+ {
822
+ public function getTests()
823
+ {
824
+ return array(
825
+ 'even' => new Twig_Test_Function('twig_test_even'),
826
+ );
827
+ }
828
+
829
+ // ...
830
+ }
831
+
832
+ Testing an Extension
833
+ --------------------
834
+
835
+ .. versionadded:: 1.10
836
+ Support for functional tests was added in Twig 1.10.
837
+
838
+ Functional Tests
839
+ ~~~~~~~~~~~~~~~~
840
+
841
+ You can create functional tests for extensions simply by creating the
842
+ following file structure in your test directory::
843
+
844
+ Fixtures/
845
+ filters/
846
+ foo.test
847
+ bar.test
848
+ functions/
849
+ foo.test
850
+ bar.test
851
+ tags/
852
+ foo.test
853
+ bar.test
854
+ IntegrationTest.php
855
+
856
+ The ``IntegrationTest.php`` file should look like this::
857
+
858
+ class Project_Tests_IntegrationTest extends Twig_Test_IntegrationTestCase
859
+ {
860
+ public function getExtensions()
861
+ {
862
+ return array(
863
+ new Project_Twig_Extension1(),
864
+ new Project_Twig_Extension2(),
865
+ );
866
+ }
867
+
868
+ public function getFixturesDir()
869
+ {
870
+ return dirname(__FILE__).'/Fixtures/';
871
+ }
872
+ }
873
+
874
+ Fixtures examples can be found within the Twig repository
875
+ `tests/Twig/Fixtures`_ directory.
876
+
877
+ Node Tests
878
+ ~~~~~~~~~~
879
+
880
+ Testing the node visitors can be complex, so extend your test cases from
881
+ ``Twig_Test_NodeTestCase``. Examples can be found in the Twig repository
882
+ `tests/Twig/Node`_ directory.

1
+ Twig for Developers
2
+ ===================
3
+
4
+ This chapter describes the API to Twig and not the template language. It will
5
+ be most useful as reference to those implementing the template interface to
6
+ the application and not those who are creating Twig templates.
7
+
8
+ Basics
9
+ ------
10
+
11
+ Twig uses a central object called the **environment** (of class
12
+ ``Twig_Environment``). Instances of this class are used to store the
13
+ configuration and extensions, and are used to load templates from the file
14
+ system or other locations.
15
+
16
+ Most applications will create one ``Twig_Environment`` object on application
17
+ initialization and use that to load templates. In some cases it's however
18
+ useful to have multiple environments side by side, if different configurations
19
+ are in use.
20
+
21
+ The simplest way to configure Twig to load templates for your application
22
+ looks roughly like this::
23
+
24
+ require_once '/path/to/lib/Twig/Autoloader.php';
25
+ Twig_Autoloader::register();
26
+
27
+ $loader = new Twig_Loader_Filesystem('/path/to/templates');
28
+ $twig = new Twig_Environment($loader, array(
29
+ 'cache' => '/path/to/compilation_cache',
30
+ ));
31
+
32
+ This will create a template environment with the default settings and a loader
33
+ that looks up the templates in the ``/path/to/templates/`` folder. Different
34
+ loaders are available and you can also write your own if you want to load
35
+ templates from a database or other resources.
36
+
37
+ .. note::
38
+
39
+ Notice that the second argument of the environment is an array of options.
40
+ The ``cache`` option is a compilation cache directory, where Twig caches
41
+ the compiled templates to avoid the parsing phase for sub-sequent
42
+ requests. It is very different from the cache you might want to add for
43
+ the evaluated templates. For such a need, you can use any available PHP
44
+ cache library.
45
+
46
+ To load a template from this environment you just have to call the
47
+ ``loadTemplate()`` method which then returns a ``Twig_Template`` instance::
48
+
49
+ $template = $twig->loadTemplate('index.html');
50
+
51
+ To render the template with some variables, call the ``render()`` method::
52
+
53
+ echo $template->render(array('the' => 'variables', 'go' => 'here'));
54
+
55
+ .. note::
56
+
57
+ The ``display()`` method is a shortcut to output the template directly.
58
+
59
+ You can also load and render the template in one fell swoop::
60
+
61
+ echo $twig->render('index.html', array('the' => 'variables', 'go' => 'here'));
62
+
63
+ .. _environment_options:
64
+
65
+ Environment Options
66
+ -------------------
67
+
68
+ When creating a new ``Twig_Environment`` instance, you can pass an array of
69
+ options as the constructor second argument::
70
+
71
+ $twig = new Twig_Environment($loader, array('debug' => true));
72
+
73
+ The following options are available:
74
+
75
+ * ``debug``: When set to ``true``, the generated templates have a
76
+ ``__toString()`` method that you can use to display the generated nodes
77
+ (default to ``false``).
78
+
79
+ * ``charset``: The charset used by the templates (default to ``utf-8``).
80
+
81
+ * ``base_template_class``: The base template class to use for generated
82
+ templates (default to ``Twig_Template``).
83
+
84
+ * ``cache``: An absolute path where to store the compiled templates, or
85
+ ``false`` to disable caching (which is the default).
86
+
87
+ * ``auto_reload``: When developing with Twig, it's useful to recompile the
88
+ template whenever the source code changes. If you don't provide a value for
89
+ the ``auto_reload`` option, it will be determined automatically based on the
90
+ ``debug`` value.
91
+
92
+ * ``strict_variables``: If set to ``false``, Twig will silently ignore invalid
93
+ variables (variables and or attributes/methods that do not exist) and
94
+ replace them with a ``null`` value. When set to ``true``, Twig throws an
95
+ exception instead (default to ``false``).
96
+
97
+ * ``autoescape``: If set to ``true``, auto-escaping will be enabled by default
98
+ for all templates (default to ``true``). As of Twig 1.8, you can set the
99
+ escaping strategy to use (``html``, ``js``, ``false`` to disable).
100
+ As of Twig 1.9, you can set the escaping strategy to use (``css``, ``url``,
101
+ ``html_attr``, or a PHP callback that takes the template "filename" and must
102
+ return the escaping strategy to use -- the callback cannot be a function name
103
+ to avoid collision with built-in escaping strategies).
104
+
105
+ * ``optimizations``: A flag that indicates which optimizations to apply
106
+ (default to ``-1`` -- all optimizations are enabled; set it to ``0`` to
107
+ disable).
108
+
109
+ Loaders
110
+ -------
111
+
112
+ Loaders are responsible for loading templates from a resource such as the file
113
+ system.
114
+
115
+ Compilation Cache
116
+ ~~~~~~~~~~~~~~~~~
117
+
118
+ All template loaders can cache the compiled templates on the filesystem for
119
+ future reuse. It speeds up Twig a lot as templates are only compiled once; and
120
+ the performance boost is even larger if you use a PHP accelerator such as APC.
121
+ See the ``cache`` and ``auto_reload`` options of ``Twig_Environment`` above
122
+ for more information.
123
+
124
+ Built-in Loaders
125
+ ~~~~~~~~~~~~~~~~
126
+
127
+ Here is a list of the built-in loaders Twig provides:
128
+
129
+ ``Twig_Loader_Filesystem``
130
+ ..........................
131
+
132
+ .. versionadded:: 1.10
133
+ The ``prependPath()`` and support for namespaces were added in Twig 1.10.
134
+
135
+ ``Twig_Loader_Filesystem`` loads templates from the file system. This loader
136
+ can find templates in folders on the file system and is the preferred way to
137
+ load them::
138
+
139
+ $loader = new Twig_Loader_Filesystem($templateDir);
140
+
141
+ It can also look for templates in an array of directories::
142
+
143
+ $loader = new Twig_Loader_Filesystem(array($templateDir1, $templateDir2));
144
+
145
+ With such a configuration, Twig will first look for templates in
146
+ ``$templateDir1`` and if they do not exist, it will fallback to look for them
147
+ in the ``$templateDir2``.
148
+
149
+ You can add or prepend paths via the ``addPath()`` and ``prependPath()``
150
+ methods::
151
+
152
+ $loader->addPath($templateDir3);
153
+ $loader->prependPath($templateDir4);
154
+
155
+ The filesystem loader also supports namespaced templates. This allows to group
156
+ your templates under different namespaces which have their own template paths.
157
+
158
+ When using the ``setPaths()``, ``addPath()``, and ``prependPath()`` methods,
159
+ specify the namespace as the second argument (when not specified, these
160
+ methods act on the "main" namespace)::
161
+
162
+ $loader->addPath($templateDir, 'admin');
163
+
164
+ Namespaced templates can be accessed via the special
165
+ ``@namespace_name/template_path`` notation::
166
+
167
+ $twig->render('@admin/index.html', array());
168
+
169
+ ``Twig_Loader_String``
170
+ ......................
171
+
172
+ ``Twig_Loader_String`` loads templates from strings. It's a dummy loader as
173
+ the template reference is the template source code::
174
+
175
+ $loader = new Twig_Loader_String();
176
+ $twig = new Twig_Environment($loader);
177
+
178
+ echo $twig->render('Hello {{ name }}!', array('name' => 'Fabien'));
179
+
180
+ This loader should only be used for unit testing as it has severe limitations:
181
+ several tags, like ``extends`` or ``include`` do not make sense to use as the
182
+ reference to the template is the template source code itself.
183
+
184
+ ``Twig_Loader_Array``
185
+ .....................
186
+
187
+ ``Twig_Loader_Array`` loads a template from a PHP array. It's passed an array
188
+ of strings bound to template names::
189
+
190
+ $loader = new Twig_Loader_Array(array(
191
+ 'index.html' => 'Hello {{ name }}!',
192
+ ));
193
+ $twig = new Twig_Environment($loader);
194
+
195
+ echo $twig->render('index.html', array('name' => 'Fabien'));
196
+
197
+ This loader is very useful for unit testing. It can also be used for small
198
+ projects where storing all templates in a single PHP file might make sense.
199
+
200
+ .. tip::
201
+
202
+ When using the ``Array`` or ``String`` loaders with a cache mechanism, you
203
+ should know that a new cache key is generated each time a template content
204
+ "changes" (the cache key being the source code of the template). If you
205
+ don't want to see your cache grows out of control, you need to take care
206
+ of clearing the old cache file by yourself.
207
+
208
+ ``Twig_Loader_Chain``
209
+ .....................
210
+
211
+ ``Twig_Loader_Chain`` delegates the loading of templates to other loaders::
212
+
213
+ $loader1 = new Twig_Loader_Array(array(
214
+ 'base.html' => '{% block content %}{% endblock %}',
215
+ ));
216
+ $loader2 = new Twig_Loader_Array(array(
217
+ 'index.html' => '{% extends "base.twig" %}{% block content %}Hello {{ name }}{% endblock %}',
218
+ 'base.html' => 'Will never be loaded',
219
+ ));
220
+
221
+ $loader = new Twig_Loader_Chain(array($loader1, $loader2));
222
+
223
+ $twig = new Twig_Environment($loader);
224
+
225
+ When looking for a template, Twig will try each loader in turn and it will
226
+ return as soon as the template is found. When rendering the ``index.html``
227
+ template from the above example, Twig will load it with ``$loader2`` but the
228
+ ``base.html`` template will be loaded from ``$loader1``.
229
+
230
+ ``Twig_Loader_Chain`` accepts any loader that implements
231
+ ``Twig_LoaderInterface``.
232
+
233
+ .. note::
234
+
235
+ You can also add loaders via the ``addLoader()`` method.
236
+
237
+ Create your own Loader
238
+ ~~~~~~~~~~~~~~~~~~~~~~
239
+
240
+ All loaders implement the ``Twig_LoaderInterface``::
241
+
242
+ interface Twig_LoaderInterface
243
+ {
244
+ /**
245
+ * Gets the source code of a template, given its name.
246
+ *
247
+ * @param string $name string The name of the template to load
248
+ *
249
+ * @return string The template source code
250
+ */
251
+ function getSource($name);
252
+
253
+ /**
254
+ * Gets the cache key to use for the cache for a given template name.
255
+ *
256
+ * @param string $name string The name of the template to load
257
+ *
258
+ * @return string The cache key
259
+ */
260
+ function getCacheKey($name);
261
+
262
+ /**
263
+ * Returns true if the template is still fresh.
264
+ *
265
+ * @param string $name The template name
266
+ * @param timestamp $time The last modification time of the cached template
267
+ */
268
+ function isFresh($name, $time);
269
+ }
270
+
271
+ As an example, here is how the built-in ``Twig_Loader_String`` reads::
272
+
273
+ class Twig_Loader_String implements Twig_LoaderInterface
274
+ {
275
+ public function getSource($name)
276
+ {
277
+ return $name;
278
+ }
279
+
280
+ public function getCacheKey($name)
281
+ {
282
+ return $name;
283
+ }
284
+
285
+ public function isFresh($name, $time)
286
+ {
287
+ return false;
288
+ }
289
+ }
290
+
291
+ The ``isFresh()`` method must return ``true`` if the current cached template
292
+ is still fresh, given the last modification time, or ``false`` otherwise.
293
+
294
+ .. tip::
295
+
296
+ As of Twig 1.11.0, you can also implement ``Twig_ExistsLoaderInterface``
297
+ to make your loader faster when used with the chain loader.
298
+
299
+ Using Extensions
300
+ ----------------
301
+
302
+ Twig extensions are packages that add new features to Twig. Using an
303
+ extension is as simple as using the ``addExtension()`` method::
304
+
305
+ $twig->addExtension(new Twig_Extension_Sandbox());
306
+
307
+ Twig comes bundled with the following extensions:
308
+
309
+ * *Twig_Extension_Core*: Defines all the core features of Twig.
310
+
311
+ * *Twig_Extension_Escaper*: Adds automatic output-escaping and the possibility
312
+ to escape/unescape blocks of code.
313
+
314
+ * *Twig_Extension_Sandbox*: Adds a sandbox mode to the default Twig
315
+ environment, making it safe to evaluated untrusted code.
316
+
317
+ * *Twig_Extension_Optimizer*: Optimizers the node tree before compilation.
318
+
319
+ The core, escaper, and optimizer extensions do not need to be added to the
320
+ Twig environment, as they are registered by default.
321
+
322
+ Built-in Extensions
323
+ -------------------
324
+
325
+ This section describes the features added by the built-in extensions.
326
+
327
+ .. tip::
328
+
329
+ Read the chapter about extending Twig to learn how to create your own
330
+ extensions.
331
+
332
+ Core Extension
333

411
+
412
+ Escaper Extension
413
+ ~~~~~~~~~~~~~~~~~
414
+
415
+ The ``escaper`` extension adds automatic output escaping to Twig. It defines a
416
+ tag, ``autoescape``, and a filter, ``raw``.
417
+
418
+ When creating the escaper extension, you can switch on or off the global
419
+ output escaping strategy::
420
+
421
+ $escaper = new Twig_Extension_Escaper(true);
422
+ $twig->addExtension($escaper);
423
+
424
+ If set to ``true``, all variables in templates are escaped (using the ``html``
425
+ escaping strategy), except those using the ``raw`` filter:
426
+
427
+ .. code-block:: jinja
428
+
429
+ {{ article.to_html|raw }}
430
+
431
+ You can also change the escaping mode locally by using the ``autoescape`` tag
432
+ (see the :doc:`autoescape<tags/autoescape>` doc for the syntax used before
433
+ Twig 1.8):
434
+
435
+ .. code-block:: jinja
436
+
437
+ {% autoescape 'html' %}
438
+ {{ var }}
439
+ {{ var|raw }} {# var won't be escaped #}
440
+ {{ var|escape }} {# var won't be double-escaped #}
441
+ {% endautoescape %}
442
+
443
+ .. warning::
444
+
445
+ The ``autoescape`` tag has no effect on included files.
446
+
447
+ The escaping rules are implemented as follows:
448
+
449
+ * Literals (integers, booleans, arrays, ...) used in the template directly as
450
+ variables or filter arguments are never automatically escaped:
451
+
452
+ .. code-block:: jinja
453
+
454
+ {{ "Twig<br />" }} {# won't be escaped #}
455
+
456
+ {% set text = "Twig<br />" %}
457
+ {{ text }} {# will be escaped #}
458
+
459
+ * Expressions which the result is always a literal or a variable marked safe
460
+ are never automatically escaped:
461
+
462
+ .. code-block:: jinja
463
+
464
+ {{ foo ? "Twig<br />" : "<br />Twig" }} {# won't be escaped #}
465
+
466
+ {% set text = "Twig<br />" %}
467
+ {{ foo ? text : "<br />Twig" }} {# will be escaped #}
468
+
469
+ {% set text = "Twig<br />" %}
470
+ {{ foo ? text|raw : "<br />Twig" }} {# won't be escaped #}
471
+
472
+ {% set text = "Twig<br />" %}
473
+ {{ foo ? text|escape : "<br />Twig" }} {# the result of the expression won't be escaped #}
474
+
475
+ * Escaping is applied before printing, after any other filter is applied:
476
+
477
+ .. code-block:: jinja
478
+
479
+ {{ var|upper }} {# is equivalent to {{ var|upper|escape }} #}
480
+
481
+ * The `raw` filter should only be used at the end of the filter chain:
482
+
483
+ .. code-block:: jinja
484
+
485
+ {{ var|raw|upper }} {# will be escaped #}
486
+
487
+ {{ var|upper|raw }} {# won't be escaped #}
488
+
489
+ * Automatic escaping is not applied if the last filter in the chain is marked
490
+ safe for the current context (e.g. ``html`` or ``js``). ``escaper`` and
491
+ ``escaper('html')`` are marked safe for html, ``escaper('js')`` is marked
492
+ safe for javascript, ``raw`` is marked safe for everything.
493
+
494
+ .. code-block:: jinja
495
+
496
+ {% autoescape 'js' %}
497
+ {{ var|escape('html') }} {# will be escaped for html and javascript #}
498
+ {{ var }} {# will be escaped for javascript #}
499
+ {{ var|escape('js') }} {# won't be double-escaped #}
500
+ {% endautoescape %}
501
+
502
+ .. note::
503
+
504
+ Note that autoescaping has some limitations as escaping is applied on
505
+ expressions after evaluation. For instance, when working with
506
+ concatenation, ``{{ foo|raw ~ bar }}`` won't give the expected result as
507
+ escaping is applied on the result of the concatenation, not on the
508
+ individual variables (so, the ``raw`` filter won't have any effect here).
509
+
510
+ Sandbox Extension
511
+ ~~~~~~~~~~~~~~~~~
512
+
513
+ The ``sandbox`` extension can be used to evaluate untrusted code. Access to
514
+ unsafe attributes and methods is prohibited. The sandbox security is managed
515
+ by a policy instance. By default, Twig comes with one policy class:
516
+ ``Twig_Sandbox_SecurityPolicy``. This class allows you to white-list some
517
+ tags, filters, properties, and methods::
518
+
519
+ $tags = array('if');
520
+ $filters = array('upper');
521
+ $methods = array(
522
+ 'Article' => array('getTitle', 'getBody'),
523
+ );
524
+ $properties = array(
525
+ 'Article' => array('title', 'body'),
526
+ );
527
+ $functions = array('range');
528
+ $policy = new Twig_Sandbox_SecurityPolicy($tags, $filters, $methods, $properties, $functions);
529
+
530
+ With the previous configuration, the security policy will only allow usage of
531
+ the ``if`` tag, and the ``upper`` filter. Moreover, the templates will only be
532
+ able to call the ``getTitle()`` and ``getBody()`` methods on ``Article``
533
+ objects, and the ``title`` and ``body`` public properties. Everything else
534
+ won't be allowed and will generate a ``Twig_Sandbox_SecurityError`` exception.
535
+
536
+ The policy object is the first argument of the sandbox constructor::
537
+
538
+ $sandbox = new Twig_Extension_Sandbox($policy);
539
+ $twig->addExtension($sandbox);
540
+
541
+ By default, the sandbox mode is disabled and should be enabled when including
542
+ untrusted template code by using the ``sandbox`` tag:
543
+
544
+ .. code-block:: jinja
545
+
546
+ {% sandbox %}
547
+ {% include 'user.html' %}
548
+ {% endsandbox %}
549
+
550
+ You can sandbox all templates by passing ``true`` as the second argument of
551
+ the extension constructor::
552
+
553
+ $sandbox = new Twig_Extension_Sandbox($policy, true);
554
+
555
+ Optimizer Extension
556
+ ~~~~~~~~~~~~~~~~~~~
557
+
558
+ The ``optimizer`` extension optimizes the node tree before compilation::
559
+
560
+ $twig->addExtension(new Twig_Extension_Optimizer());
561
+
562
+ By default, all optimizations are turned on. You can select the ones you want
563
+ to enable by passing them to the constructor::
564
+
565
+ $optimizer = new Twig_Extension_Optimizer(Twig_NodeVisitor_Optimizer::OPTIMIZE_FOR);
566
+
567
+ $twig->addExtension($optimizer);
568
+
569
+ Exceptions
570
+ ----------
571
+
572
+ Twig can throw exceptions:
573
+
574
+ * ``Twig_Error``: The base exception for all errors.
575
+
576
+ * ``Twig_Error_Syntax``: Thrown to tell the user that there is a problem with
577
+ the template syntax.
578
+
579
+ * ``Twig_Error_Runtime``: Thrown when an error occurs at runtime (when a filter
580
+ does not exist for instance).
581
+
582
+ * ``Twig_Error_Loader``: Thrown when an error occurs during template loading.
583
+
584
+ * ``Twig_Sandbox_SecurityError``: Thrown when an unallowed tag, filter, or
585
+ method is called in a sandboxed template.

1
+ Coding Standards
2
+ ================
3
+
4
+ When writing Twig templates, we recommend you to follow these official coding
5
+ standards:
6
+
7
+ * Put one (and only one) space after the start of a delimiter (``{{``, ``{%``,
8
+ and ``{#``) and before the end of a delimiter (``}}``, ``%}``, and ``#}``):
9
+
10
+ .. code-block:: jinja
11
+
12
+ {{ foo }}
13
+ {# comment #}
14
+ {% if foo %}{% endif %}
15
+
16
+ When using the whitespace control character, do not put any spaces between
17
+ it and the delimiter:
18
+
19
+ .. code-block:: jinja
20
+
21
+ {{- foo -}}
22
+ {#- comment -#}
23
+ {%- if foo -%}{%- endif -%}
24
+
25
+ * Put one (and only one) space before and after the following operators:
26
+ comparison operators (``==``, ``!=``, ``<``, ``>``, ``>=``, ``<=``), math
27
+ operators (``+``, ``-``, ``/``, ``*``, ``%``, ``//``, ``**``), logic
28
+ operators (``not``, ``and``, ``or``), ``~``, ``is``, ``in``, and the ternary
29
+ operator (``?:``):
30
+
31
+ .. code-block:: jinja
32
+
33
+ {{ 1 + 2 }}
34
+ {{ foo ~ bar }}
35
+ {{ true ? true : false }}
36
+
37
+ * Put one (and only one) space after the ``:`` sign in hashes and ``,`` in
38
+ arrays and hashes:
39
+
40
+ .. code-block:: jinja
41
+
42
+ {{ [1, 2, 3] }}
43
+ {{ {'foo': 'bar'} }}
44
+
45
+ * Do not put any spaces after an opening parenthesis and before a closing
46
+ parenthesis in expressions:
47
+
48
+ .. code-block:: jinja
49
+
50
+ {{ 1 + (2 * 3) }}
51
+
52
+ * Do not put any spaces before and after string delimiters:
53
+
54
+ .. code-block:: jinja
55
+
56
+ {{ 'foo' }}
57
+ {{ "foo" }}
58
+
59
+ * Do not put any spaces before and after the following operators: ``|``,
60
+ ``.``, ``..``, ``[]``:
61
+
62
+ .. code-block:: jinja
63
+
64
+ {{ foo|upper|lower }}
65
+ {{ user.name }}
66
+ {{ user[name] }}
67
+ {% for i in 1..12 %}{% endfor %}
68
+
69
+ * Do not put any spaces before and after the parenthesis used for filter and
70
+ function calls:
71
+
72
+ .. code-block:: jinja
73
+
74
+ {{ foo|default('foo') }}
75
+ {{ range(1..10) }}
76
+
77
+ * Do not put any spaces before and after the opening and the closing of arrays
78
+ and hashes:
79
+
80
+ .. code-block:: jinja
81
+
82
+ {{ [1, 2, 3] }}
83
+ {{ {'foo': 'bar'} }}
84
+
85
+ * Use lower cased and underscored variable names:
86
+
87
+ .. code-block:: jinja
88
+
89
+ {% set foo = 'foo' %}
90
+ {% set foo_bar = 'foo' %}
91
+
92
+ * Indent your code inside tags (use the same indentation as the one used for
93
+ the main language of the file):
94
+
95
+ .. code-block:: jinja
96
+
97
+ {% block foo %}
98
+ {% if true %}
99
+ true
100
+ {% endif %}
101

1
+ Deprecated Features
2
+ ===================
3
+
4
+ This document lists all deprecated features in Twig. Deprecated features are
5
+ kept for backward compatibility and removed in the next major release (a
6
+ feature that was deprecated in Twig 1.x is removed in Twig 2.0).
7
+
8
+ Token Parsers
9
+ -------------
10
+
11
+ * As of Twig 1.x, the token parser broker sub-system is deprecated. The
12
+ following class and interface will be removed in 2.0:
13
+
14
+ * ``Twig_TokenParserBrokerInterface``
15
+ * ``Twig_TokenParserBroker``
16
+
17
+ Extensions
18
+ ----------
19
+
20
+ * As of Twig 1.x, the ability to remove an extension is deprecated and the
21
+ ``Twig_Environment::removeExtension()`` method will be removed in 2.0.
22
+
23
+ PEAR
24
+ ----
25
+
26
+ PEAR support will be discontinued in Twig 2.0, and no PEAR packages will be
27
+ provided. Use Composer instead.
28
+
29
+ Filters
30
+ -------
31
+
32
+ * As of Twig 1.x, use ``Twig_SimpleFilter`` to add a filter. The following
33

36
+ * ``Twig_FilterCallableInterface``
37
+ * ``Twig_Filter``
38
+ * ``Twig_Filter_Function``
39
+ * ``Twig_Filter_Method``
40
+ * ``Twig_Filter_Node``
41
+
42
+ * As of Twig 2.x, the ``Twig_SimpleFilter`` class is deprecated and will be
43
+ removed in Twig 3.x (use ``Twig_Filter`` instead). In Twig 2.x,
44
+ ``Twig_SimpleFilter`` is just an alias for ``Twig_Filter``.
45
+
46
+ Functions
47
+ ---------
48
+
49

58
+
59
+ * As of Twig 2.x, the ``Twig_SimpleFunction`` class is deprecated and will be
60
+ removed in Twig 3.x (use ``Twig_Function`` instead). In Twig 2.x,
61
+ ``Twig_SimpleFunction`` is just an alias for ``Twig_Function``.
62
+
63
+ Tests
64
+ -----
65
+
66
+ * As of Twig 1.x, use ``Twig_SimpleTest`` to add a test. The following classes
67

73
+ * ``Twig_Test_Method``
74
+ * ``Twig_Test_Node``
75
+
76
+ * As of Twig 2.x, the ``Twig_SimpleTest`` class is deprecated and will be
77
+ removed in Twig 3.x (use ``Twig_Test`` instead). In Twig 2.x,
78
+ ``Twig_SimpleTest`` is just an alias for ``Twig_Test``.
79
+
80
+ Interfaces
81
+ ----------
82
+
83
+ * As of Twig 2.x, the following interfaces are deprecated and empty (they will
84
+ be removed in Twig 3.0):
85
+
86
+ * ``Twig_CompilerInterface`` (use ``Twig_Compiler`` instead)
87

90
+ * ``Twig_ExistsLoaderInterface`` (merged with ``Twig_LoaderInterface``)
91
+ * ``Twig_TemplateInterface`` (use ``Twig_Template`` instead)
92
+
93
+ Globals
94
+ -------
95
+
96
+ * As of Twig 2.x, the ability to register a global variable after the runtime
97
+ or the extensions have been initialized is not possible anymore (but
98
+ changing the value of an already registered global is possible).

+ ``convert_encoding``
2
+ ====================
3
+
4
+ .. versionadded:: 1.4
5
+ The ``convert_encoding`` filter was added in Twig 1.4.
6
+
7
+ The ``convert_encoding`` filter converts a string from one encoding to
8
+ another. The first argument is the expected output charset and the second one
9
+ is the input charset:
10
+
11
+ .. code-block:: jinja
12
+
13
+ {{ data|convert_encoding('UTF-8', 'iso-2022-jp') }}
14
+
15
+ .. note::
16
+
17
+ This filter relies on the `iconv`_ or `mbstring`_ extension, so one of
18
+ them must be installed. In case both are installed, `mbstring`_ is used by
19
+ default (Twig before 1.8.1 uses `iconv`_ by default).

1
+ ``date``
2
+ ========
3
+
4
+ .. versionadded:: 1.1
5
+ The timezone support has been added in Twig 1.1.
6
+
7
+ .. versionadded:: 1.5
8
+ The default date format support has been added in Twig 1.5.
9
+
10
+ .. versionadded:: 1.6.1
11
+ The default timezone support has been added in Twig 1.6.1.
12
+
13
+ .. versionadded:: 1.11.0
14
+ The introduction of the false value for the timezone was introduced in Twig 1.11.0
15
+
16
+ The ``date`` filter formats a date to a given format:
17
+
18
+ .. code-block:: jinja
19
+
20
+ {{ post.published_at|date("m/d/Y") }}
21
+
22
+ The ``date`` filter accepts strings (it must be in a format supported by the
23
+ `strtotime`_ function), `DateTime`_ instances, or `DateInterval`_ instances. For
24
+ instance, to display the current date, filter the word "now":
25
+
26
+ .. code-block:: jinja
27
+
28
+ {{ "now"|date("m/d/Y") }}
29
+
30
+ To escape words and characters in the date format use ``\\`` in front of each
31
+ character:
32
+
33
+ .. code-block:: jinja
34
+
35
+ {{ post.published_at|date("F jS \\a\\t g:ia") }}
36
+
37
+ If the value passed to the ``date`` filter is ``null``, it will return the
38
+ current date by default. If an empty string is desired instead of the current
39
+ date, use a ternary operator:
40
+
41
+ .. code-block:: jinja
42
+
43
+ {{ post.published_at is empty ? "" : post.published_at|date("m/d/Y") }}
44
+
45
+ If no format is provided, Twig will use the default one: ``F j, Y H:i``. This
46
+ default can be easily changed by calling the ``setDateFormat()`` method on the
47
+ ``core`` extension instance. The first argument is the default format for
48
+ dates and the second one is the default format for date intervals:
49
+
50
+ .. code-block:: php
51
+
52
+ $twig = new Twig_Environment($loader);
53
+ $twig->getExtension('core')->setDateFormat('d/m/Y', '%d days');
54
+
55
+ Timezone
56
+ --------
57
+
58
+ By default, the date is displayed by applying the default timezone (the one
59
+ specified in php.ini or declared in Twig -- see below), but you can override
60
+ it by explicitly specifying a timezone:
61
+
62
+ .. code-block:: jinja
63
+
64
+ {{ post.published_at|date("m/d/Y", "Europe/Paris") }}
65
+
66
+ If the date is already a DateTime object, and if you want to keep its current
67
+ timezone, pass ``false`` as the timezone value:
68
+
69
+ .. code-block:: jinja
70
+
71
+ {{ post.published_at|date("m/d/Y", false) }}
72
+
73
+ The default timezone can also be set globally by calling ``setTimezone()``:
74
+
75
+ .. code-block:: php
76
+
77
+ $twig = new Twig_Environment($loader);
78
+ $twig->getExtension('core')->setTimezone('Europe/Paris');
79

+ ``escape``
2
+ ==========
3
+
4
+ .. versionadded:: 1.9.0
5
+ The ``css``, ``url``, and ``html_attr`` strategies were added in Twig
6
+ 1.9.0.
7
+
8
+ The ``escape`` filter escapes a string for safe insertion into the final
9
+ output. It supports different escaping strategies depending on the template
10
+ context.
11
+
12
+ By default, it uses the HTML escaping strategy:
13
+
14
+ .. code-block:: jinja
15
+
16
+ {{ user.username|escape }}
17
+
18
+ For convenience, the ``e`` filter is defined as an alias:
19
+
20
+ .. code-block:: jinja
21
+
22
+ {{ user.username|e }}
23
+
24
+ The ``escape`` filter can also be used in other contexts than HTML thanks to
25
+ an optional argument which defines the escaping strategy to use:
26
+
27
+ .. code-block:: jinja
28
+
29
+ {{ user.username|e }}
30
+ {# is equivalent to #}
31
+ {{ user.username|e('html') }}
32
+
33
+ And here is how to escape variables included in JavaScript code:
34
+
35
+ .. code-block:: jinja
36
+
37
+ {{ user.username|escape('js') }}
38
+ {{ user.username|e('js') }}
39
+
40
+ The ``escape`` filter supports the following escaping strategies:
41
+
42
+ * ``html``: escapes a string for the **HTML body** context.
43
+
44
+ * ``js``: escapes a string for the **JavaScript context**.
45
+
46
+ * ``css``: escapes a string for the **CSS context**. CSS escaping can be
47
+ applied to any string being inserted into CSS and escapes everything except
48
+ alphanumerics.
49
+
50
+ * ``url``: escapes a string for the **URI or parameter contexts**. This should
51
+ not be used to escape an entire URI; only a subcomponent being inserted.
52
+
53
+ * ``html_attr``: escapes a string for the **HTML attribute** context.
54
+
55
+ .. note::
56
+
57
+ Internally, ``escape`` uses the PHP native `htmlspecialchars`_ function
58
+ for the HTML escaping strategy.
59
+
60
+ .. caution::
61
+
62
+ When using automatic escaping, Twig tries to not double-escape a variable
63
+ when the automatic escaping strategy is the same as the one applied by the
64
+ escape filter; but that does not work when using a variable as the
65
+ escaping strategy:
66
+
67
+ .. code-block:: jinja
68
+
69
+ {% set strategy = 'html' %}
70
+
71
+ {% autoescape 'html' %}
72
+ {{ var|escape('html') }} {# won't be double-escaped #}
73
+ {{ var|escape(strategy) }} {# will be double-escaped #}
74
+ {% endautoescape %}
75
+
76
+ When using a variable as the escaping strategy, you should disable
77
+ automatic escaping:
78
+
79
+ .. code-block:: jinja
80
+
81
+ {% set strategy = 'html' %}
82
+
83
+ {% autoescape 'html' %}
84

3

4

5
+ The number_format filter was added in Twig 1.5
6
+
7
+ The ``number_format`` filter formats numbers. It is a wrapper around PHP's
8
+ `number_format`_ function:
9
+
10
+ .. code-block:: jinja
11
+
12
+ {{ 200.35|number_format }}
13
+
14
+ You can control the number of decimal places, decimal point, and thousands
15
+ separator using the additional arguments:
16
+
17
+ .. code-block:: jinja
18
+
19
+ {{ 9800.333|number_format(2, '.', ',') }}
20
+
21
+ If no formatting options are provided then Twig will use the default formatting
22
+ options of:
23
+
24
+ - 0 decimal places.
25
+ - ``.`` as the decimal point.
26
+ - ``,`` as the thousands separator.
27
+
28
+ These defaults can be easily changed through the core extension:
29
+
30
+ .. code-block:: php
31
+
32
+ $twig = new Twig_Environment($loader);
33
+ $twig->getExtension('core')->setNumberFormat(3, '.', ',');
34
+
35
+ The defaults set for ``number_format`` can be over-ridden upon each call using the
36
+ additional parameters.
37
+
38
+ Arguments
39
+ ---------
40
+
41
+ * ``decimal``: The number of decimal points to display
42

2
+ ===========
3
+
4
+ .. versionadded:: 1.6
5
+ The slice filter was added in Twig 1.6.
6
+
7
+ The ``slice`` filter extracts a slice of a sequence, a mapping, or a string:
8
+
9
+ .. code-block:: jinja
10
+
11
+ {% for i in [1, 2, 3, 4]|slice(1, 2) %}
12
+ {# will iterate over 2 and 3 #}
13
+ {% endfor %}
14
+
15
+ {{ '1234'|slice(1, 2) }}
16
+
17
+ {# outputs 23 #}
18
+
19
+ You can use any valid expression for both the start and the length:
20
+
21
+ .. code-block:: jinja
22
+
23
+ {% for i in [1, 2, 3, 4]|slice(start, length) %}
24
+ {# ... #}
25
+ {% endfor %}
26
+
27
+ As syntactic sugar, you can also use the ``[]`` notation:
28
+
29
+ .. code-block:: jinja
30
+
31
+ {% for i in [1, 2, 3, 4][start:length] %}
32
+ {# ... #}
33
+ {% endfor %}
34
+
35
+ {{ '1234'[1:2] }}
36
+
37
+ {# you can omit the first argument -- which is the same as 0 #}
38
+ {{ '1234'[:2] }} {# will display "12" #}
39
+
40
+ {# you can omit the last argument -- which will select everything till the end #}
41
+ {{ '1234'[2:] }} {# will display "34 #}
42
+
43
+ The ``slice`` filter works as the `array_slice`_ PHP function for arrays and
44
+ `substr`_ for strings.
45
+
46
+ If the start is non-negative, the sequence will start at that start in the
47
+ variable. If start is negative, the sequence will start that far from the end
48
+ of the variable.
49
+
50
+ If length is given and is positive, then the sequence will have up to that
51
+ many elements in it. If the variable is shorter than the length, then only the
52
+ available variable elements will be present. If length is given and is
53
+ negative then the sequence will stop that many elements from the end of the
54
+ variable. If it is omitted, then the sequence will have everything from offset
55
+ up until the end of the variable.
56
+
57
+ .. note::
58
+
59
+ It also works with objects implementing the `Traversable`_ interface.

17
+
18
+ The argument must be in a format supported by the `date`_ function.
19
+
20
+ You can pass a timezone as the second argument:

28
+ If no argument is passed, the function returns the current date:
29
+
30
+ .. code-block:: jinja
31
+
32
+ {% if date(user.created_at) < date() %}
33
+ {# always! #}
34
+ {% endif %}
35
+
36
+ .. note::
37
+
38
+ You can set the default timezone globally by calling ``setTimezone()`` on
39

+ ``dump``
2
+ ========
3
+
4
+ .. versionadded:: 1.5
5
+ The dump function was added in Twig 1.5.
6
+
7
+ The ``dump`` function dumps information about a template variable. This is
8
+ mostly useful to debug a template that does not behave as expected by
9
+ introspecting its variables:
10
+
11
+ .. code-block:: jinja
12
+
13
+ {{ dump(user) }}
14
+
15
+ .. note::
16
+
17
+ The ``dump`` function is not available by default. You must add the
18
+ ``Twig_Extension_Debug`` extension explicitly when creating your Twig
19
+ environment::
20
+
21
+ $twig = new Twig_Environment($loader, array(
22
+ 'debug' => true,
23
+ // ...
24
+ ));
25
+ $twig->addExtension(new Twig_Extension_Debug());
26
+
27
+ Even when enabled, the ``dump`` function won't display anything if the
28
+ ``debug`` option on the environment is not enabled (to avoid leaking debug
29
+ information on a production server).
30
+
31
+ In an HTML context, wrap the output with a ``pre`` tag to make it easier to
32
+ read:
33
+
34
+ .. code-block:: jinja
35
+
36
+ <pre>
37
+ {{ dump(user) }}
38
+ </pre>
39
+
40
+ .. tip::
41
+
42
+ Using a ``pre`` tag is not needed when `XDebug`_ is enabled and
43
+ ``html_errors`` is ``on``; as a bonus, the output is also nicer with
44
+ XDebug enabled.
45
+
46
+ You can debug several variables by passing them as additional arguments:
47
+
48
+ .. code-block:: jinja
49
+
50
+ {{ dump(user, categories) }}
51
+
52
+ If you don't pass any value, all variables from the current context are
53
+ dumped:
54
+
55
+ .. code-block:: jinja
56
+
57
+ {{ dump() }}
58
+
59
+ .. note::
60
+
61
+ Internally, Twig uses the PHP `var_dump`_ function.
62
+
63
+ Arguments
64
+ ---------
65
+
66
+ * ``context``: The context to dump
67

+ ``include``
2
+ ===========
3
+
4
+ .. versionadded:: 1.12
5
+ The include function was added in Twig 1.12.
6
+
7
+ The ``include`` function returns the rendered content of a template:
8
+
9
+ .. code-block:: jinja
10
+
11
+ {{ include('template.html') }}
12
+ {{ include(some_var) }}
13
+
14
+ Included templates have access to the variables of the active context.
15
+
16
+ If you are using the filesystem loader, the templates are looked for in the
17
+ paths defined by it.
18
+
19
+ The context is passed by default to the template but you can also pass
20
+ additional variables:
21
+
22
+ .. code-block:: jinja
23
+
24
+ {# template.html will have access to the variables from the current context and the additional ones provided #}
25
+ {{ include('template.html', {foo: 'bar'}) }}
26
+
27
+ You can disable access to the context by setting ``with_context`` to
28
+ ``false``:
29
+
30
+ .. code-block:: jinja
31
+
32
+ {# only the foo variable will be accessible #}
33
+ {{ include('template.html', {foo: 'bar'}, with_context = false) }}
34
+
35
+ .. code-block:: jinja
36
+
37
+ {# no variables will be accessible #}
38
+ {{ include('template.html', with_context = false) }}
39
+
40
+ And if the expression evaluates to a ``Twig_Template`` object, Twig will use it
41
+ directly::
42
+
43
+ // {{ include(template) }}
44
+
45
+ $template = $twig->loadTemplate('some_template.twig');
46
+
47
+ $twig->loadTemplate('template.twig')->display(array('template' => $template));
48
+
49
+ When you set the ``ignore_missing`` flag, Twig will return an empty string if
50
+ the template does not exist:
51
+
52
+ .. code-block:: jinja
53
+
54
+ {{ include('sidebar.html', ignore_missing = true) }}
55
+
56
+ You can also provide a list of templates that are checked for existence before
57
+ inclusion. The first template that exists will be rendered:
58
+
59
+ .. code-block:: jinja
60
+
61
+ {{ include(['page_detailed.html', 'page.html']) }}
62
+
63
+ If ``ignore_missing`` is set, it will fall back to rendering nothing if none
64
+ of the templates exist, otherwise it will throw an exception.
65
+
66
+ When including a template created by an end user, you should consider
67
+ sandboxing it:
68
+
69
+ .. code-block:: jinja
70
+
71
+ {{ include('page.html', sandboxed = true) }}
72
+
73
+ Arguments
74
+ ---------
75
+
76
+ * ``template``: The template to render
77
+ * ``variables``: The variables to pass to the template
78
+ * ``with_context``: Whether to pass the current context variables or not
79

+ Twig Internals
2
+ ==============
3
+
4
+ Twig is very extensible and you can easily hack it. Keep in mind that you
5
+ should probably try to create an extension before hacking the core, as most
6
+ features and enhancements can be done with extensions. This chapter is also
7
+ useful for people who want to understand how Twig works under the hood.
8
+
9
+ How Twig works?
10
+ ---------------
11
+
12
+ The rendering of a Twig template can be summarized into four key steps:
13
+
14
+ * **Load** the template: If the template is already compiled, load it and go
15
+ to the *evaluation* step, otherwise:
16
+
17
+ * First, the **lexer** tokenizes the template source code into small pieces
18
+ for easier processing;
19
+ * Then, the **parser** converts the token stream into a meaningful tree
20
+ of nodes (the Abstract Syntax Tree);
21
+ * Eventually, the *compiler* transforms the AST into PHP code;
22
+
23
+ * **Evaluate** the template: It basically means calling the ``display()``
24
+ method of the compiled template and passing it the context.
25
+
26
+ The Lexer
27
+ ---------
28
+
29
+ The lexer tokenizes a template source code into a token stream (each token is
30
+ an instance of ``Twig_Token``, and the stream is an instance of
31
+ ``Twig_TokenStream``). The default lexer recognizes 13 different token types:
32
+
33
+ * ``Twig_Token::BLOCK_START_TYPE``, ``Twig_Token::BLOCK_END_TYPE``: Delimiters for blocks (``{% %}``)
34
+ * ``Twig_Token::VAR_START_TYPE``, ``Twig_Token::VAR_END_TYPE``: Delimiters for variables (``{{ }}``)
35
+ * ``Twig_Token::TEXT_TYPE``: A text outside an expression;
36
+ * ``Twig_Token::NAME_TYPE``: A name in an expression;
37
+ * ``Twig_Token::NUMBER_TYPE``: A number in an expression;
38
+ * ``Twig_Token::STRING_TYPE``: A string in an expression;
39
+ * ``Twig_Token::OPERATOR_TYPE``: An operator;
40
+ * ``Twig_Token::PUNCTUATION_TYPE``: A punctuation sign;
41
+ * ``Twig_Token::INTERPOLATION_START_TYPE``, ``Twig_Token::INTERPOLATION_END_TYPE`` (as of Twig 1.5): Delimiters for string interpolation;
42
+ * ``Twig_Token::EOF_TYPE``: Ends of template.
43
+
44
+ You can manually convert a source code into a token stream by calling the
45
+ ``tokenize()`` of an environment::
46
+
47
+ $stream = $twig->tokenize($source, $identifier);
48
+
49
+ As the stream has a ``__toString()`` method, you can have a textual
50
+ representation of it by echoing the object::
51
+
52
+ echo $stream."\n";
53
+
54
+ Here is the output for the ``Hello {{ name }}`` template:
55
+
56
+ .. code-block:: text
57
+
58
+ TEXT_TYPE(Hello )
59
+ VAR_START_TYPE()
60
+ NAME_TYPE(name)
61
+ VAR_END_TYPE()
62
+ EOF_TYPE()
63
+
64
+ .. note::
65
+
66
+ You can change the default lexer use by Twig (``Twig_Lexer``) by calling
67
+ the ``setLexer()`` method::
68
+
69
+ $twig->setLexer($lexer);
70
+
71
+ The Parser
72
+ ----------
73
+
74
+ The parser converts the token stream into an AST (Abstract Syntax Tree), or a
75
+ node tree (an instance of ``Twig_Node_Module``). The core extension defines
76
+ the basic nodes like: ``for``, ``if``, ... and the expression nodes.
77
+
78
+ You can manually convert a token stream into a node tree by calling the
79
+ ``parse()`` method of an environment::
80
+
81
+ $nodes = $twig->parse($stream);
82
+
83
+ Echoing the node object gives you a nice representation of the tree::
84
+
85
+ echo $nodes."\n";
86
+
87
+ Here is the output for the ``Hello {{ name }}`` template:
88
+
89
+ .. code-block:: text
90
+
91
+ Twig_Node_Module(
92
+ Twig_Node_Text(Hello )
93
+ Twig_Node_Print(
94
+ Twig_Node_Expression_Name(name)
95
+ )
96
+ )
97
+
98
+ .. note::
99
+
100
+ The default parser (``Twig_TokenParser``) can be also changed by calling the
101
+ ``setParser()`` method::
102
+
103
+ $twig->setParser($parser);
104
+
105
+ The Compiler
106
+ ------------
107
+
108
+ The last step is done by the compiler. It takes a node tree as an input and
109
+ generates PHP code usable for runtime execution of the template.
110
+
111
+ You can call the compiler by hand with the ``compile()`` method of an
112
+ environment::
113
+
114
+ $php = $twig->compile($nodes);
115
+
116
+ The ``compile()`` method returns the PHP source code representing the node.
117
+
118
+ The generated template for a ``Hello {{ name }}`` template reads as follows
119
+ (the actual output can differ depending on the version of Twig you are
120
+ using)::
121
+
122
+ /* Hello {{ name }} */
123
+ class __TwigTemplate_1121b6f109fe93ebe8c6e22e3712bceb extends Twig_Template
124
+ {
125
+ protected function doDisplay(array $context, array $blocks = array())
126
+ {
127
+ // line 1
128
+ echo "Hello ";
129
+ echo twig_escape_filter($this->env, $this->getContext($context, "name"), "ndex", null, true);
130
+ }
131
+
132
+ // some more code
133
+ }
134
+
135
+ .. note::
136
+
137
+ As for the lexer and the parser, the default compiler (``Twig_Compiler``) can
138
+ be changed by calling the ``setCompiler()`` method::
139
+
140

1
+ Introduction
2
+ ============
3
+
4
+ This is the documentation for Twig, the flexible, fast, and secure template
5
+ engine for PHP.
6
+
7
+ If you have any exposure to other text-based template languages, such as
8
+ Smarty, Django, or Jinja, you should feel right at home with Twig. It's both
9
+ designer and developer friendly by sticking to PHP's principles and adding
10
+ functionality useful for templating environments.
11
+
12
+ The key-features are...
13
+
14
+ * *Fast*: Twig compiles templates down to plain optimized PHP code. The
15
+ overhead compared to regular PHP code was reduced to the very minimum.
16
+
17
+ * *Secure*: Twig has a sandbox mode to evaluate untrusted template code. This
18
+ allows Twig to be used as a template language for applications where users
19
+ may modify the template design.
20
+
21
+ * *Flexible*: Twig is powered by a flexible lexer and parser. This allows the
22
+ developer to define its own custom tags and filters, and create its own DSL.
23
+
24
+ Prerequisites
25
+ -------------
26
+
27
+ Twig needs at least **PHP 5.2.4** to run.
28
+
29
+ Installation
30
+ ------------
31
+
32
+ You have multiple ways to install Twig.
33
+
34
+ Installing via Composer (recommended)
35
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
36
+
37
+ 1. Install composer in your project:
38
+
39
+ .. code-block:: bash
40
+
41
+ curl -s http://getcomposer.org/installer | php
42
+
43
+ 2. Create a ``composer.json`` file in your project root:
44
+
45
+ .. code-block:: javascript
46
+
47
+ {
48
+ "require": {
49
+ "twig/twig": "1.*"
50
+ }
51
+ }
52
+
53
+ 3. Install via composer
54
+
55
+ .. code-block:: bash
56
+
57
+ php composer.phar install
58
+
59
+ .. note::
60
+ If you want to learn more about Composer, the ``composer.json`` file syntax
61
+ and its usage, you can read the `online documentation`_.
62
+
63
+ Installing from the tarball release
64
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
65
+
66
+ 1. Download the most recent tarball from the `download page`_
67
+ 2. Unpack the tarball
68
+ 3. Move the files somewhere in your project
69
+
70
+ Installing the development version
71
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
72
+
73
+ 1. Install Git
74
+ 2. ``git clone git://github.com/fabpot/Twig.git``
75
+
76
+ Installing the PEAR package
77
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~
78
+
79
+ 1. Install PEAR
80
+ 2. ``pear channel-discover pear.twig-project.org``
81
+ 3. ``pear install twig/Twig`` (or ``pear install twig/Twig-beta``)
82
+
83
+
84
+ Installing the C extension
85
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~
86
+
87
+ .. versionadded:: 1.4
88
+ The C extension was added in Twig 1.4.
89
+
90
+ Twig comes with a C extension that enhances the performance of the Twig
91
+ runtime engine. You can install it like any other PHP extension:
92
+
93
+ .. code-block:: bash
94
+
95
+ $ cd ext/twig
96
+ $ phpize
97
+ $ ./configure
98
+ $ make
99
+ $ make install
100
+
101
+ Finally, enable the extension in your ``php.ini`` configuration file:
102
+
103
+ .. code-block:: ini
104
+
105
+ extension=twig.so
106
+
107
+ And from now on, Twig will automatically compile your templates to take
108
+ advantage of the C extension. Note that this extension does not replace the
109
+ PHP code but only provides an optimized version of the
110
+ ``Twig_Template::getAttribute()`` method.
111
+
112
+ .. tip::
113
+
114
+ On Windows, you can also simply download and install a `pre-build DLL`_.
115
+
116
+ Basic API Usage
117
+ ---------------
118
+
119
+ This section gives you a brief introduction to the PHP API for Twig.
120
+
121
+ The first step to use Twig is to register its autoloader::
122
+
123
+ require_once '/path/to/lib/Twig/Autoloader.php';
124
+ Twig_Autoloader::register();
125
+
126
+ Replace the ``/path/to/lib/`` path with the path you used for Twig
127
+ installation.
128
+
129
+ If you have installed Twig via Composer you can take advantage of Composer's
130
+ autoload mechanism by replacing the previous snippet for::
131
+
132
+ require_once '/path/to/vendor/autoload.php'
133
+
134
+ .. note::
135
+
136
+ Twig follows the PEAR convention names for its classes, which means you
137
+ can easily integrate Twig classes loading in your own autoloader.
138
+
139
+ .. code-block:: php
140
+
141
+ $loader = new Twig_Loader_String();
142
+ $twig = new Twig_Environment($loader);
143
+
144
+ echo $twig->render('Hello {{ name }}!', array('name' => 'Fabien'));
145
+
146
+ Twig uses a loader (``Twig_Loader_String``) to locate templates, and an
147
+ environment (``Twig_Environment``) to store the configuration.
148
+
149
+ The ``render()`` method loads the template passed as a first argument and
150
+ renders it with the variables passed as a second argument.
151
+
152
+ As templates are generally stored on the filesystem, Twig also comes with a
153
+ filesystem loader::
154
+
155
+ $loader = new Twig_Loader_Filesystem('/path/to/templates');
156
+ $twig = new Twig_Environment($loader, array(
157
+ 'cache' => '/path/to/compilation_cache',
158
+ ));
159
+
160
+ echo $twig->render('index.html', array('name' => 'Fabien'));

+ Recipes
2
+ =======
3
+
4
+ Making a Layout conditional
5
+ ---------------------------
6
+
7
+ Working with Ajax means that the same content is sometimes displayed as is,
8
+ and sometimes decorated with a layout. As Twig layout template names can be
9
+ any valid expression, you can pass a variable that evaluates to ``true`` when
10
+ the request is made via Ajax and choose the layout accordingly:
11
+
12
+ .. code-block:: jinja
13
+
14
+ {% extends request.ajax ? "base_ajax.html" : "base.html" %}
15
+
16
+ {% block content %}
17
+ This is the content to be displayed.
18
+ {% endblock %}
19
+
20
+ Making an Include dynamic
21
+ -------------------------
22
+
23
+ When including a template, its name does not need to be a string. For
24
+ instance, the name can depend on the value of a variable:
25
+
26
+ .. code-block:: jinja
27
+
28
+ {% include var ~ '_foo.html' %}
29
+
30
+ If ``var`` evaluates to ``index``, the ``index_foo.html`` template will be
31
+ rendered.
32
+
33
+ As a matter of fact, the template name can be any valid expression, such as
34
+ the following:
35
+
36
+ .. code-block:: jinja
37
+
38
+ {% include var|default('index') ~ '_foo.html' %}
39
+
40
+ Overriding a Template that also extends itself
41
+ ----------------------------------------------
42
+
43
+ A template can be customized in two different ways:
44
+
45
+ * *Inheritance*: A template *extends* a parent template and overrides some
46
+ blocks;
47
+
48
+ * *Replacement*: If you use the filesystem loader, Twig loads the first
49
+ template it finds in a list of configured directories; a template found in a
50
+ directory *replaces* another one from a directory further in the list.
51
+
52
+ But how do you combine both: *replace* a template that also extends itself
53
+ (aka a template in a directory further in the list)?
54
+
55
+ Let's say that your templates are loaded from both ``.../templates/mysite``
56
+ and ``.../templates/default`` in this order. The ``page.twig`` template,
57
+ stored in ``.../templates/default`` reads as follows:
58
+
59
+ .. code-block:: jinja
60
+
61
+ {# page.twig #}
62
+ {% extends "layout.twig" %}
63
+
64
+ {% block content %}
65
+ {% endblock %}
66
+
67
+ You can replace this template by putting a file with the same name in
68
+ ``.../templates/mysite``. And if you want to extend the original template, you
69
+ might be tempted to write the following:
70
+
71
+ .. code-block:: jinja
72
+
73
+ {# page.twig in .../templates/mysite #}
74
+ {% extends "page.twig" %} {# from .../templates/default #}
75
+
76
+ Of course, this will not work as Twig will always load the template from
77
+ ``.../templates/mysite``.
78
+
79
+ It turns out it is possible to get this to work, by adding a directory right
80
+ at the end of your template directories, which is the parent of all of the
81
+ other directories: ``.../templates`` in our case. This has the effect of
82
+ making every template file within our system uniquely addressable. Most of the
83
+ time you will use the "normal" paths, but in the special case of wanting to
84
+ extend a template with an overriding version of itself we can reference its
85
+ parent's full, unambiguous template path in the extends tag:
86
+
87
+ .. code-block:: jinja
88
+
89
+ {# page.twig in .../templates/mysite #}
90
+ {% extends "default/page.twig" %} {# from .../templates #}
91
+
92
+ .. note::
93
+
94
+ This recipe was inspired by the following Django wiki page:
95
+ http://code.djangoproject.com/wiki/ExtendingTemplates
96
+
97
+ Customizing the Syntax
98
+ ----------------------
99
+
100
+ Twig allows some syntax customization for the block delimiters. It's not
101
+ recommended to use this feature as templates will be tied with your custom
102
+ syntax. But for specific projects, it can make sense to change the defaults.
103
+
104
+ To change the block delimiters, you need to create your own lexer object::
105
+
106
+ $twig = new Twig_Environment();
107
+
108
+ $lexer = new Twig_Lexer($twig, array(
109
+ 'tag_comment' => array('{#', '#}'),
110
+ 'tag_block' => array('{%', '%}'),
111
+ 'tag_variable' => array('{{', '}}'),
112
+ ));
113
+ $twig->setLexer($lexer);
114
+
115
+ Here are some configuration example that simulates some other template engines
116
+ syntax::
117
+
118
+ // Ruby erb syntax
119
+ $lexer = new Twig_Lexer($twig, array(
120
+ 'tag_comment' => array('<%#', '%>'),
121
+ 'tag_block' => array('<%', '%>'),
122
+ 'tag_variable' => array('<%=', '%>'),
123
+ ));
124
+
125
+ // SGML Comment Syntax
126
+ $lexer = new Twig_Lexer($twig, array(
127
+ 'tag_comment' => array('<!--#', '-->'),
128
+ 'tag_block' => array('<!--', '-->'),
129
+ 'tag_variable' => array('${', '}'),
130
+ ));
131
+
132
+ // Smarty like
133
+ $lexer = new Twig_Lexer($twig, array(
134
+ 'tag_comment' => array('{*', '*}'),
135
+ 'tag_block' => array('{', '}'),
136
+ 'tag_variable' => array('{$', '}'),
137
+ ));
138
+
139
+ Using dynamic Object Properties
140
+ -------------------------------
141
+
142
+ When Twig encounters a variable like ``article.title``, it tries to find a
143
+ ``title`` public property in the ``article`` object.
144
+
145
+ It also works if the property does not exist but is rather defined dynamically
146
+ thanks to the magic ``__get()`` method; you just need to also implement the
147
+ ``__isset()`` magic method like shown in the following snippet of code::
148
+
149
+ class Article
150
+ {
151
+ public function __get($name)
152
+ {
153
+ if ('title' == $name) {
154
+ return 'The title';
155
+ }
156
+
157
+ // throw some kind of error
158
+ }
159
+
160
+ public function __isset($name)
161
+ {
162
+ if ('title' == $name) {
163
+ return true;
164
+ }
165
+
166
+ return false;
167
+ }
168
+ }
169
+
170
+ Accessing the parent Context in Nested Loops
171
+ --------------------------------------------
172
+
173
+ Sometimes, when using nested loops, you need to access the parent context. The
174
+ parent context is always accessible via the ``loop.parent`` variable. For
175
+ instance, if you have the following template data::
176
+
177
+ $data = array(
178
+ 'topics' => array(
179
+ 'topic1' => array('Message 1 of topic 1', 'Message 2 of topic 1'),
180
+ 'topic2' => array('Message 1 of topic 2', 'Message 2 of topic 2'),
181
+ ),
182
+ );
183
+
184
+ And the following template to display all messages in all topics:
185
+
186
+ .. code-block:: jinja
187
+
188
+ {% for topic, messages in topics %}
189
+ * {{ loop.index }}: {{ topic }}
190
+ {% for message in messages %}
191
+ - {{ loop.parent.loop.index }}.{{ loop.index }}: {{ message }}
192
+ {% endfor %}
193
+ {% endfor %}
194
+
195
+ The output will be similar to:
196
+
197
+ .. code-block:: text
198
+
199
+ * 1: topic1
200
+ - 1.1: The message 1 of topic 1
201
+ - 1.2: The message 2 of topic 1
202
+ * 2: topic2
203
+ - 2.1: The message 1 of topic 2
204
+ - 2.2: The message 2 of topic 2
205
+
206
+ In the inner loop, the ``loop.parent`` variable is used to access the outer
207
+ context. So, the index of the current ``topic`` defined in the outer for loop
208
+ is accessible via the ``loop.parent.loop.index`` variable.
209
+
210
+ Defining undefined Functions and Filters on the Fly
211
+ ---------------------------------------------------
212
+
213
+ When a function (or a filter) is not defined, Twig defaults to throw a
214
+ ``Twig_Error_Syntax`` exception. However, it can also call a `callback`_ (any
215
+ valid PHP callable) which should return a function (or a filter).
216
+
217
+ For filters, register callbacks with ``registerUndefinedFilterCallback()``.
218
+ For functions, use ``registerUndefinedFunctionCallback()``::
219
+
220
+ // auto-register all native PHP functions as Twig functions
221
+ // don't try this at home as it's not secure at all!
222
+ $twig->registerUndefinedFunctionCallback(function ($name) {
223
+ if (function_exists($name)) {
224
+ return new Twig_Function_Function($name);
225
+ }
226
+
227
+ return false;
228
+ });
229
+
230
+ If the callable is not able to return a valid function (or filter), it must
231
+ return ``false``.
232
+
233
+ If you register more than one callback, Twig will call them in turn until one
234
+ does not return ``false``.
235
+
236
+ .. tip::
237
+
238
+ As the resolution of functions and filters is done during compilation,
239
+ there is no overhead when registering these callbacks.
240
+
241
+ Validating the Template Syntax
242
+ ------------------------------
243
+
244
+ When template code is providing by a third-party (through a web interface for
245
+ instance), it might be interesting to validate the template syntax before
246
+ saving it. If the template code is stored in a `$template` variable, here is
247
+ how you can do it::
248
+
249
+ try {
250
+ $twig->parse($twig->tokenize($template));
251
+
252
+ // the $template is valid
253
+ } catch (Twig_Error_Syntax $e) {
254
+ // $template contains one or more syntax errors
255
+ }
256
+
257
+ If you iterate over a set of files, you can pass the filename to the
258
+ ``tokenize()`` method to get the filename in the exception message::
259
+
260
+ foreach ($files as $file) {
261
+ try {
262
+ $twig->parse($twig->tokenize($template, $file));
263
+
264
+ // the $template is valid
265
+ } catch (Twig_Error_Syntax $e) {
266
+ // $template contains one or more syntax errors
267
+ }
268
+ }
269
+
270
+ .. note::
271
+
272
+ This method won't catch any sandbox policy violations because the policy
273
+ is enforced during template rendering (as Twig needs the context for some
274
+ checks like allowed methods on objects).
275
+
276
+ Refreshing modified Templates when APC is enabled and apc.stat = 0
277
+ ------------------------------------------------------------------
278
+
279
+ When using APC with ``apc.stat`` set to ``0`` and Twig cache enabled, clearing
280
+ the template cache won't update the APC cache. To get around this, one can
281
+ extend ``Twig_Environment`` and force the update of the APC cache when Twig
282
+ rewrites the cache::
283
+
284
+ class Twig_Environment_APC extends Twig_Environment
285
+ {
286
+ protected function writeCacheFile($file, $content)
287
+ {
288
+ parent::writeCacheFile($file, $content);
289
+
290
+ // Compile cached file into bytecode cache
291
+ apc_compile_file($file);
292
+ }
293
+ }
294
+
295
+ Reusing a stateful Node Visitor
296
+ -------------------------------
297
+
298
+ When attaching a visitor to a ``Twig_Environment`` instance, Twig uses it to
299
+ visit *all* templates it compiles. If you need to keep some state information
300
+ around, you probably want to reset it when visiting a new template.
301
+
302
+ This can be easily achieved with the following code::
303
+
304
+ protected $someTemplateState = array();
305
+
306
+ public function enterNode(Twig_NodeInterface $node, Twig_Environment $env)
307
+ {
308
+ if ($node instanceof Twig_Node_Module) {
309
+ // reset the state as we are entering a new template
310
+ $this->someTemplateState = array();
311
+ }
312
+
313
+ // ...
314
+
315
+ return $node;
316
+ }
317
+
318
+ Using the Template name to set the default Escaping Strategy
319
+ ------------------------------------------------------------
320
+
321
+ .. versionadded:: 1.8
322
+ This recipe requires Twig 1.8 or later.
323
+
324
+ The ``autoescape`` option determines the default escaping strategy to use when
325
+ no escaping is applied on a variable. When Twig is used to mostly generate
326
+ HTML files, you can set it to ``html`` and explicitly change it to ``js`` when
327
+ you have some dynamic JavaScript files thanks to the ``autoescape`` tag:
328
+
329
+ .. code-block:: jinja
330
+
331
+ {% autoescape 'js' %}
332
+ ... some JS ...
333
+ {% endautoescape %}
334
+
335
+ But if you have many HTML and JS files, and if your template names follow some
336
+ conventions, you can instead determine the default escaping strategy to use
337
+ based on the template name. Let's say that your template names always ends
338
+ with ``.html`` for HTML files, ``.js`` for JavaScript ones, and ``.css`` for
339
+ stylesheets, here is how you can configure Twig::
340
+
341
+ class TwigEscapingGuesser
342
+ {
343
+ function guess($filename)
344
+ {
345
+ // get the format
346
+ $format = substr($filename, strrpos($filename, '.') + 1);
347
+
348
+ switch ($format) {
349
+ case 'js':
350
+ return 'js';
351
+ case 'css':
352
+ return 'css';
353
+ case 'html':
354
+ default:
355
+ return 'html';
356
+ }
357
+ }
358
+ }
359
+
360
+ $loader = new Twig_Loader_Filesystem('/path/to/templates');
361
+ $twig = new Twig_Environment($loader, array(
362
+ 'autoescape' => array(new TwigEscapingGuesser(), 'guess'),
363
+ ));
364
+
365
+ This dynamic strategy does not incur any overhead at runtime as auto-escaping
366
+ is done at compilation time.
367
+
368
+ Using a Database to store Templates
369
+ -----------------------------------
370
+
371
+ If you are developing a CMS, templates are usually stored in a database. This
372
+ recipe gives you a simple PDO template loader you can use as a starting point
373
+ for your own.
374
+
375
+ First, let's create a temporary in-memory SQLite3 database to work with::
376
+
377
+ $dbh = new PDO('sqlite::memory:');
378
+ $dbh->exec('CREATE TABLE templates (name STRING, source STRING, last_modified INTEGER)');
379
+ $base = '{% block content %}{% endblock %}';
380
+ $index = '
381
+ {% extends "base.twig" %}
382
+ {% block content %}Hello {{ name }}{% endblock %}
383
+ ';
384
+ $now = time();
385
+ $dbh->exec("INSERT INTO templates (name, source, last_modified) VALUES ('base.twig', '$base', $now)");
386
+ $dbh->exec("INSERT INTO templates (name, source, last_modified) VALUES ('index.twig', '$index', $now)");
387
+
388
+ We have created a simple ``templates`` table that hosts two templates:
389
+ ``base.twig`` and ``index.twig``.
390
+
391
+ Now, let's define a loader able to use this database::
392
+
393
+ class DatabaseTwigLoader implements Twig_LoaderInterface, Twig_ExistsLoaderInterface
394
+ {
395
+ protected $dbh;
396
+
397
+ public function __construct(PDO $dbh)
398
+ {
399
+ $this->dbh = $dbh;
400
+ }
401
+
402
+ public function getSource($name)
403
+ {
404
+ if (false === $source = $this->getValue('source', $name)) {
405
+ throw new Twig_Error_Loader(sprintf('Template "%s" does not exist.', $name));
406
+ }
407
+
408
+ return $source;
409
+ }
410
+
411
+ // Twig_ExistsLoaderInterface as of Twig 1.11
412
+ public function exists($name)
413
+ {
414
+ return $name === $this->getValue('name', $name);
415
+ }
416
+
417
+ public function getCacheKey($name)
418
+ {
419
+ return $name;
420
+ }
421
+
422
+ public function isFresh($name, $time)
423
+ {
424
+ if (false === $lastModified = $this->getValue('last_modified', $name)) {
425
+ return false;
426
+ }
427
+
428
+ return $lastModified <= $time;
429
+ }
430
+
431
+ protected function getValue($column, $name)
432
+ {
433
+ $sth = $this->dbh->prepare('SELECT '.$column.' FROM templates WHERE name = :name');
434
+ $sth->execute(array(':name' => (string) $name));
435
+
436
+ return $sth->fetchColumn();
437
+ }
438
+ }
439
+
440
+ Finally, here is an example on how you can use it::
441
+
442
+ $loader = new DatabaseTwigLoader($dbh);
443
+ $twig = new Twig_Environment($loader);
444
+
445
+ echo $twig->render('index.twig', array('name' => 'Fabien'));
446
+
447
+ Using different Template Sources
448
+ --------------------------------
449
+
450
+ This recipe is the continuation of the previous one. Even if you store the
451
+ contributed templates in a database, you might want to keep the original/base
452
+ templates on the filesystem. When templates can be loaded from different
453
+ sources, you need to use the ``Twig_Loader_Chain`` loader.
454
+
455
+ As you can see in the previous recipe, we reference the template in the exact
456
+ same way as we would have done it with a regular filesystem loader. This is
457
+ the key to be able to mix and match templates coming from the database, the
458
+ filesystem, or any other loader for that matter: the template name should be a
459
+ logical name, and not the path from the filesystem::
460
+
461
+ $loader1 = new DatabaseTwigLoader($dbh);
462
+ $loader2 = new Twig_Loader_Array(array(
463
+ 'base.twig' => '{% block content %}{% endblock %}',
464
+ ));
465
+ $loader = new Twig_Loader_Chain(array($loader1, $loader2));
466
+
467
+ $twig = new Twig_Environment($loader);
468
+
469
+ echo $twig->render('index.twig', array('name' => 'Fabien'));
470
+
471
+ Now that the ``base.twig`` templates is defined in an array loader, you can
472
+ remove it from the database, and everything else will still work as before.
473
+

+ ``autoescape``
2
+ ==============
3
+
4
+ Whether automatic escaping is enabled or not, you can mark a section of a
5
+ template to be escaped or not by using the ``autoescape`` tag:
6
+
7
+ .. code-block:: jinja
8
+
9
+ {# The following syntax works as of Twig 1.8 -- see the note below for previous versions #}
10
+
11
+ {% autoescape %}
12
+ Everything will be automatically escaped in this block
13
+ using the HTML strategy
14
+ {% endautoescape %}
15
+
16
+ {% autoescape 'html' %}
17
+ Everything will be automatically escaped in this block
18
+ using the HTML strategy
19
+ {% endautoescape %}
20
+
21
+ {% autoescape 'js' %}
22
+ Everything will be automatically escaped in this block
23
+ using the js escaping strategy
24
+ {% endautoescape %}
25
+
26
+ {% autoescape false %}
27
+ Everything will be outputted as is in this block
28
+ {% endautoescape %}
29
+
30
+ .. note::
31
+
32
+ Before Twig 1.8, the syntax was different:
33
+
34
+ .. code-block:: jinja
35
+
36
+ {% autoescape true %}
37
+ Everything will be automatically escaped in this block
38
+ using the HTML strategy
39
+ {% endautoescape %}
40
+
41
+ {% autoescape false %}
42
+ Everything will be outputted as is in this block
43
+ {% endautoescape %}
44
+
45
+ {% autoescape true js %}
46
+ Everything will be automatically escaped in this block
47
+ using the js escaping strategy
48
+ {% endautoescape %}
49
+
50
+ When automatic escaping is enabled everything is escaped by default except for
51
+ values explicitly marked as safe. Those can be marked in the template by using
52
+ the :doc:`raw<../filters/raw>` filter:
53
+
54
+ .. code-block:: jinja
55
+
56
+ {% autoescape %}
57
+ {{ safe_value|raw }}
58
+ {% endautoescape %}
59
+
60
+ Functions returning template data (like :doc:`macros<macro>` and
61
+ :doc:`parent<../functions/parent>`) always return safe markup.
62
+
63
+ .. note::
64
+
65
+ Twig is smart enough to not escape an already escaped value by the
66
+ :doc:`escape<../filters/escape>` filter.
67
+
68
+ .. note::
69
+
70
+ The chapter :doc:`Twig for Developers<../api>` gives more information
71
+ about when and how automatic escaping is applied.

+ ``embed``
2
+ =========
3
+
4
+ .. versionadded:: 1.8
5
+ The ``embed`` tag was added in Twig 1.8.
6
+
7
+ The ``embed`` tag combines the behaviour of :doc:`include<include>` and
8
+ :doc:`extends<extends>`.
9
+ It allows you to include another template's contents, just like ``include``
10
+ does. But it also allows you to override any block defined inside the
11
+ included template, like when extending a template.
12
+
13
+ Think of an embedded template as a "micro layout skeleton".
14
+
15
+ .. code-block:: jinja
16
+
17
+ {% embed "teasers_skeleton.twig" %}
18
+ {# These blocks are defined in "teasers_skeleton.twig" #}
19
+ {# and we override them right here: #}
20
+ {% block left_teaser %}
21
+ Some content for the left teaser box
22
+ {% endblock %}
23
+ {% block right_teaser %}
24
+ Some content for the right teaser box
25
+ {% endblock %}
26
+ {% endembed %}
27
+
28
+ The ``embed`` tag takes the idea of template inheritance to the level of
29
+ content fragments. While template inheritance allows for "document skeletons",
30
+ which are filled with life by child templates, the ``embed`` tag allows you to
31
+ create "skeletons" for smaller units of content and re-use and fill them
32
+ anywhere you like.
33
+
34
+ Since the use case may not be obvious, let's look at a simplified example.
35
+ Imagine a base template shared by multiple HTML pages, defining a single block
36
+ named "content":
37
+
38
+ .. code-block:: text
39
+
40
+ ┌─── page layout ─────────────────────┐
41
+ │ │
42
+ │ ┌── block "content" ──┐ │
43
+ │ │ │ │
44
+ │ │ │ │
45
+ │ │ (child template to │ │
46
+ │ │ put content here) │ │
47
+ │ │ │ │
48
+ │ │ │ │
49
+ │ └─────────────────────┘ │
50
+ │ │
51
+ └─────────────────────────────────────┘
52
+
53
+ Some pages ("foo" and "bar") share the same content structure -
54
+ two vertically stacked boxes:
55
+
56
+ .. code-block:: text
57
+
58
+ ┌─── page layout ─────────────────────┐
59
+ │ │
60
+ │ ┌── block "content" ──┐ │
61
+ │ │ ┌─ block "top" ───┐ │ │
62
+ │ │ │ │ │ │
63
+ │ │ └─────────────────┘ │ │
64
+ │ │ ┌─ block "bottom" ┐ │ │
65
+ │ │ │ │ │ │
66
+ │ │ └─────────────────┘ │ │
67
+ │ └─────────────────────┘ │
68
+ │ │
69
+ └─────────────────────────────────────┘
70
+
71
+ While other pages ("boom" and "baz") share a different content structure -
72
+ two boxes side by side:
73
+
74
+ .. code-block:: text
75
+
76
+ ┌─── page layout ─────────────────────┐
77
+ │ │
78
+ │ ┌── block "content" ──┐ │
79
+ │ │ │ │
80
+ │ │ ┌ block ┐ ┌ block ┐ │ │
81
+ │ │ │"left" │ │"right"│ │ │
82
+ │ │ │ │ │ │ │ │
83
+ │ │ │ │ │ │ │ │
84
+ │ │ └───────┘ └───────┘ │ │
85
+ │ └─────────────────────┘ │
86
+ │ │
87
+ └─────────────────────────────────────┘
88
+
89
+ Without the ``embed`` tag, you have two ways to design your templates:
90
+
91
+ * Create two "intermediate" base templates that extend the master layout
92
+ template: one with vertically stacked boxes to be used by the "foo" and
93
+ "bar" pages and another one with side-by-side boxes for the "boom" and
94
+ "baz" pages.
95
+
96
+ * Embed the markup for the top/bottom and left/right boxes into each page
97
+ template directly.
98
+
99
+ These two solutions do not scale well because they each have a major drawback:
100
+
101
+ * The first solution may indeed work for this simplified example. But imagine
102
+ we add a sidebar, which may again contain different, recurring structures
103
+ of content. Now we would need to create intermediate base templates for
104
+ all occurring combinations of content structure and sidebar structure...
105
+ and so on.
106
+
107
+ * The second solution involves duplication of common code with all its negative
108
+ consequences: any change involves finding and editing all affected copies
109
+ of the structure, correctness has to be verified for each copy, copies may
110
+ go out of sync by careless modifications etc.
111
+
112
+ In such a situation, the ``embed`` tag comes in handy. The common layout
113
+ code can live in a single base template, and the two different content structures,
114
+ let's call them "micro layouts" go into separate templates which are embedded
115
+ as necessary:
116
+
117
+ Page template ``foo.twig``:
118
+
119
+ .. code-block:: jinja
120
+
121
+ {% extends "layout_skeleton.twig" %}
122
+
123
+ {% block content %}
124
+ {% embed "vertical_boxes_skeleton.twig" %}
125
+ {% block top %}
126
+ Some content for the top box
127
+ {% endblock %}
128
+
129
+ {% block bottom %}
130
+ Some content for the bottom box
131
+ {% endblock %}
132
+ {% endembed %}
133
+ {% endblock %}
134
+
135
+ And here is the code for ``vertical_boxes_skeleton.twig``:
136
+
137
+ .. code-block:: html+jinja
138
+
139
+ <div class="top_box">
140
+ {% block top %}
141
+ Top box default content
142
+ {% endblock %}
143
+ </div>
144
+
145
+ <div class="bottom_box">
146
+ {% block bottom %}
147
+ Bottom box default content
148
+ {% endblock %}
149
+ </div>
150
+
151
+ The goal of the ``vertical_boxes_skeleton.twig`` template being to factor
152
+ out the HTML markup for the boxes.
153
+
154
+ The ``embed`` tag takes the exact same arguments as the ``include`` tag:
155
+
156
+ .. code-block:: jinja
157
+
158
+ {% embed "base" with {'foo': 'bar'} %}
159
+ ...
160
+ {% endembed %}
161
+
162
+ {% embed "base" with {'foo': 'bar'} only %}
163
+ ...
164
+ {% endembed %}
165
+
166
+ {% embed "base" ignore missing %}
167
+ ...
168
+ {% endembed %}
169
+
170
+ .. warning::
171
+
172
+ As embedded templates do not have "names", auto-escaping strategies based
173
+ on the template "filename" won't work as expected if you change the
174
+ context (for instance, if you embed a CSS/JavaScript template into an HTML
175
+ one). In that case, explicitly set the default auto-escaping strategy with
176
+ the ``autoescape`` tag.

+

+ ``extends``
2
+ ===========
3
+
4
+ The ``extends`` tag can be used to extend a template from another one.
5
+
6
+ .. note::
7
+
8
+ Like PHP, Twig does not support multiple inheritance. So you can only have
9
+ one extends tag called per rendering. However, Twig supports horizontal
10
+ :doc:`reuse<use>`.
11
+
12
+ Let's define a base template, ``base.html``, which defines a simple HTML
13
+ skeleton document:
14
+
15
+ .. code-block:: html+jinja
16
+
17
+ <!DOCTYPE html>
18
+ <html>
19
+ <head>
20
+ {% block head %}
21
+ <link rel="stylesheet" href="style.css" />
22
+ <title>{% block title %}{% endblock %} - My Webpage</title>
23
+ {% endblock %}
24
+ </head>
25
+ <body>
26
+ <div id="content">{% block content %}{% endblock %}</div>
27
+ <div id="footer">
28
+ {% block footer %}
29
+ &copy; Copyright 2011 by <a href="http://domain.invalid/">you</a>.
30
+ {% endblock %}
31
+ </div>
32
+ </body>
33
+ </html>
34
+
35
+ In this example, the :doc:`block<block>` tags define four blocks that child
36
+ templates can fill in.
37
+
38
+ All the ``block`` tag does is to tell the template engine that a child
39
+ template may override those portions of the template.
40
+
41
+ Child Template
42
+ --------------
43
+
44
+ A child template might look like this:
45
+
46
+ .. code-block:: jinja
47
+
48
+ {% extends "base.html" %}
49
+
50
+ {% block title %}Index{% endblock %}
51
+ {% block head %}
52
+ {{ parent() }}
53
+ <style type="text/css">
54
+ .important { color: #336699; }
55
+ </style>
56
+ {% endblock %}
57
+ {% block content %}
58
+ <h1>Index</h1>
59
+ <p class="important">
60
+ Welcome on my awesome homepage.
61
+ </p>
62
+ {% endblock %}
63
+
64
+ The ``extends`` tag is the key here. It tells the template engine that this
65
+ template "extends" another template. When the template system evaluates this
66
+ template, first it locates the parent. The extends tag should be the first tag
67
+ in the template.
68
+
69
+ Note that since the child template doesn't define the ``footer`` block, the
70
+ value from the parent template is used instead.
71
+
72
+ You can't define multiple ``block`` tags with the same name in the same
73
+ template. This limitation exists because a block tag works in "both"
74
+ directions. That is, a block tag doesn't just provide a hole to fill - it also
75
+ defines the content that fills the hole in the *parent*. If there were two
76
+ similarly-named ``block`` tags in a template, that template's parent wouldn't
77
+ know which one of the blocks' content to use.
78
+
79
+ If you want to print a block multiple times you can however use the
80
+ ``block`` function:
81
+
82
+ .. code-block:: jinja
83
+
84
+ <title>{% block title %}{% endblock %}</title>
85
+ <h1>{{ block('title') }}</h1>
86
+ {% block body %}{% endblock %}
87
+
88
+ Parent Blocks
89
+ -------------
90
+
91
+ It's possible to render the contents of the parent block by using the
92
+ :doc:`parent<../functions/parent>` function. This gives back the results of
93
+ the parent block:
94
+
95
+ .. code-block:: jinja
96
+
97
+ {% block sidebar %}
98
+ <h3>Table Of Contents</h3>
99
+ ...
100
+ {{ parent() }}
101
+ {% endblock %}
102
+
103
+ Named Block End-Tags
104
+ --------------------
105
+
106
+ Twig allows you to put the name of the block after the end tag for better
107
+ readability:
108
+
109
+ .. code-block:: jinja
110
+
111
+ {% block sidebar %}
112
+ {% block inner_sidebar %}
113
+ ...
114
+ {% endblock inner_sidebar %}
115
+ {% endblock sidebar %}
116
+
117
+ Of course, the name after the ``endblock`` word must match the block name.
118
+
119
+ Block Nesting and Scope
120
+ -----------------------
121
+
122
+ Blocks can be nested for more complex layouts. Per default, blocks have access
123
+ to variables from outer scopes:
124
+
125
+ .. code-block:: jinja
126
+
127
+ {% for item in seq %}
128
+ <li>{% block loop_item %}{{ item }}{% endblock %}</li>
129
+ {% endfor %}
130
+
131
+ Block Shortcuts
132
+ ---------------
133
+
134
+ For blocks with few content, it's possible to use a shortcut syntax. The
135
+ following constructs do the same:
136
+
137
+ .. code-block:: jinja
138
+
139
+ {% block title %}
140
+ {{ page_title|title }}
141
+ {% endblock %}
142
+
143
+ .. code-block:: jinja
144
+
145
+ {% block title page_title|title %}
146
+
147
+ Dynamic Inheritance
148
+ -------------------
149
+
150
+ Twig supports dynamic inheritance by using a variable as the base template:
151
+
152
+ .. code-block:: jinja
153
+
154
+ {% extends some_var %}
155
+
156
+ If the variable evaluates to a ``Twig_Template`` object, Twig will use it as
157
+ the parent template::
158
+
159
+ // {% extends layout %}
160
+
161
+ $layout = $twig->loadTemplate('some_layout_template.twig');
162
+
163
+ $twig->display('template.twig', array('layout' => $layout));
164
+
165
+ .. versionadded:: 1.2
166
+ The possibility to pass an array of templates has been added in Twig 1.2.
167
+
168
+ You can also provide a list of templates that are checked for existence. The
169
+ first template that exists will be used as a parent:
170
+
171
+ .. code-block:: jinja
172
+
173
+ {% extends ['layout.html', 'base_layout.html'] %}
174
+
175
+ Conditional Inheritance
176
+ -----------------------
177
+
178
+ As the template name for the parent can be any valid Twig expression, it's
179
+ possible to make the inheritance mechanism conditional:
180
+
181
+ .. code-block:: jinja
182
+
183
+ {% extends standalone ? "minimum.html" : "base.html" %}
184
+
185
+ In this example, the template will extend the "minimum.html" layout template
186
+ if the ``standalone`` variable evaluates to ``true``, and "base.html"
187
+ otherwise.
188
+
189
+ How blocks work?
190
+ ----------------
191
+
192
+ A block provides a way to change how a certain part of a template is rendered
193
+ but it does not interfere in any way with the logic around it.
194
+
195
+ Let's take the following example to illustrate how a block work and more
196
+ importantly, how it does not work:
197
+
198
+ .. code-block:: jinja
199
+
200
+ {# base.twig #}
201
+
202
+ {% for post in posts %}
203
+ {% block post %}
204
+ <h1>{{ post.title }}</h1>
205
+ <p>{{ post.body }}</p>
206
+ {% endblock %}
207
+ {% endfor %}
208
+
209
+ If you render this template, the result would be exactly the same with or
210
+ without the ``block`` tag. The ``block`` inside the ``for`` loop is just a way
211
+ to make it overridable by a child template:
212
+
213
+ .. code-block:: jinja
214
+
215
+ {# child.twig #}
216
+
217
+ {% extends "base.twig" %}
218
+
219
+ {% block post %}
220
+ <article>
221
+ <header>{{ post.title }}</header>
222
+ <section>{{ post.text }}</section>
223
+ </article>
224
+ {% endblock %}
225
+
226
+ Now, when rendering the child template, the loop is going to use the block
227
+ defined in the child template instead of the one defined in the base one; the
228
+ executed template is then equivalent to the following one:
229
+
230
+ .. code-block:: jinja
231
+
232
+ {% for post in posts %}
233
+ <article>
234
+ <header>{{ post.title }}</header>
235
+ <section>{{ post.text }}</section>
236
+ </article>
237
+ {% endfor %}
238
+
239
+ Let's take another example: a block included within an ``if`` statement:
240
+
241
+ .. code-block:: jinja
242
+
243
+ {% if posts is empty %}
244
+ {% block head %}
245
+ {{ parent() }}
246
+
247
+ <meta name="robots" content="noindex, follow">
248
+ {% endblock head %}
249
+ {% endif %}
250
+
251
+ Contrary to what you might think, this template does not define a block
252
+ conditionally; it just makes overridable by a child template the output of
253
+ what will be rendered when the condition is ``true``.
254
+
255
+ If you want the output to be displayed conditionally, use the following
256
+ instead:
257
+
258
+ .. code-block:: jinja
259
+
260
+ {% block head %}
261
+ {{ parent() }}
262
+
263
+ {% if posts is empty %}
264
+ <meta name="robots" content="noindex, follow">
265
+ {% endif %}
266
+ {% endblock head %}

+ ``for``
2
+ =======
3
+
4
+ Loop over each item in a sequence. For example, to display a list of users
5
+ provided in a variable called ``users``:
6
+
7
+ .. code-block:: jinja
8
+
9
+ <h1>Members</h1>
10
+ <ul>
11
+ {% for user in users %}
12
+ <li>{{ user.username|e }}</li>
13
+ {% endfor %}
14
+ </ul>
15
+
16
+ .. note::
17
+
18
+ A sequence can be either an array or an object implementing the
19
+ ``Traversable`` interface.
20
+
21
+ If you do need to iterate over a sequence of numbers, you can use the ``..``
22
+ operator:
23
+
24
+ .. code-block:: jinja
25
+
26
+ {% for i in 0..10 %}
27
+ * {{ i }}
28
+ {% endfor %}
29
+
30
+ The above snippet of code would print all numbers from 0 to 10.
31
+
32
+ It can be also useful with letters:
33
+
34
+ .. code-block:: jinja
35
+
36
+ {% for letter in 'a'..'z' %}
37
+ * {{ letter }}
38
+ {% endfor %}
39
+
40
+ The ``..`` operator can take any expression at both sides:
41
+
42
+ .. code-block:: jinja
43
+
44
+ {% for letter in 'a'|upper..'z'|upper %}
45
+ * {{ letter }}
46
+ {% endfor %}
47
+
48
+ .. tip:
49
+
50
+ If you need a step different from 1, you can use the ``range`` function
51
+ instead.
52
+
53
+ The `loop` variable
54
+ -------------------
55
+
56
+ Inside of a ``for`` loop block you can access some special variables:
57
+
58
+ ===================== =============================================================
59
+ Variable Description
60
+ ===================== =============================================================
61
+ ``loop.index`` The current iteration of the loop. (1 indexed)
62
+ ``loop.index0`` The current iteration of the loop. (0 indexed)
63
+ ``loop.revindex`` The number of iterations from the end of the loop (1 indexed)
64
+ ``loop.revindex0`` The number of iterations from the end of the loop (0 indexed)
65
+ ``loop.first`` True if first iteration
66
+ ``loop.last`` True if last iteration
67
+ ``loop.length`` The number of items in the sequence
68
+ ``loop.parent`` The parent context
69
+ ===================== =============================================================
70
+
71
+ .. code-block:: jinja
72
+
73
+ {% for user in users %}
74
+ {{ loop.index }} - {{ user.username }}
75
+ {% endfor %}
76
+
77
+ .. note::
78
+
79
+ The ``loop.length``, ``loop.revindex``, ``loop.revindex0``, and
80
+ ``loop.last`` variables are only available for PHP arrays, or objects that
81
+ implement the ``Countable`` interface. They are also not available when
82
+ looping with a condition.
83
+
84
+ .. versionadded:: 1.2
85
+ The ``if`` modifier support has been added in Twig 1.2.
86
+
87
+ Adding a condition
88
+ ------------------
89
+
90
+ Unlike in PHP, it's not possible to ``break`` or ``continue`` in a loop. You
91
+ can however filter the sequence during iteration which allows you to skip
92
+ items. The following example skips all the users which are not active:
93
+
94
+ .. code-block:: jinja
95
+
96
+ <ul>
97
+ {% for user in users if user.active %}
98
+ <li>{{ user.username|e }}</li>
99
+ {% endfor %}
100
+ </ul>
101
+
102
+ The advantage is that the special loop variable will count correctly thus not
103
+ counting the users not iterated over. Keep in mind that properties like
104
+ ``loop.last`` will not be defined when using loop conditions.
105
+
106
+ .. note::
107
+
108
+ Using the ``loop`` variable within the condition is not recommended as it
109
+ will probably not be doing what you expect it to. For instance, adding a
110
+ condition like ``loop.index > 4`` won't work as the index is only
111
+ incremented when the condition is true (so the condition will never
112
+ match).
113
+
114
+ The `else` Clause
115
+ -----------------
116
+
117
+ If no iteration took place because the sequence was empty, you can render a
118
+ replacement block by using ``else``:
119
+
120
+ .. code-block:: jinja
121
+
122
+ <ul>
123
+ {% for user in users %}
124
+ <li>{{ user.username|e }}</li>
125
+ {% else %}
126
+ <li><em>no user found</em></li>
127
+ {% endfor %}
128
+ </ul>
129
+
130
+ Iterating over Keys
131
+ -------------------
132
+
133
+ By default, a loop iterates over the values of the sequence. You can iterate
134
+ on keys by using the ``keys`` filter:
135
+
136
+ .. code-block:: jinja
137
+
138
+ <h1>Members</h1>
139
+ <ul>
140
+ {% for key in users|keys %}
141
+ <li>{{ key }}</li>
142
+ {% endfor %}
143
+ </ul>
144
+
145
+ Iterating over Keys and Values
146
+ ------------------------------
147
+
148
+ You can also access both keys and values:
149
+
150
+ .. code-block:: jinja
151
+
152
+ <h1>Members</h1>
153
+ <ul>
154
+ {% for key, user in users %}
155
+ <li>{{ key }}: {{ user.username|e }}</li>
156

29

+ ``import``
2
+ ==========
3
+
4
+ Twig supports putting often used code into :doc:`macros<../tags/macro>`. These
5
+ macros can go into different templates and get imported from there.
6
+
7
+ There are two ways to import templates. You can import the complete template
8
+ into a variable or request specific macros from it.
9
+
10
+ Imagine we have a helper module that renders forms (called ``forms.html``):
11
+
12
+ .. code-block:: jinja
13
+
14
+ {% macro input(name, value, type, size) %}
15
+ <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
16
+ {% endmacro %}
17
+
18
+ {% macro textarea(name, value, rows) %}
19
+ <textarea name="{{ name }}" rows="{{ rows|default(10) }}" cols="{{ cols|default(40) }}">{{ value|e }}</textarea>
20
+ {% endmacro %}
21
+
22
+ The easiest and most flexible is importing the whole module into a variable.
23
+ That way you can access the attributes:
24
+
25
+ .. code-block:: jinja
26
+
27
+ {% import 'forms.html' as forms %}
28
+
29
+ <dl>
30
+ <dt>Username</dt>
31
+ <dd>{{ forms.input('username') }}</dd>
32
+ <dt>Password</dt>
33
+ <dd>{{ forms.input('password', null, 'password') }}</dd>
34
+ </dl>
35
+ <p>{{ forms.textarea('comment') }}</p>
36
+
37
+ Alternatively you can import names from the template into the current
38
+ namespace:
39
+
40
+ .. code-block:: jinja
41
+
42
+ {% from 'forms.html' import input as input_field, textarea %}
43
+
44
+ <dl>
45
+ <dt>Username</dt>
46
+ <dd>{{ input_field('username') }}</dd>
47
+ <dt>Password</dt>
48
+ <dd>{{ input_field('password', '', 'password') }}</dd>
49
+ </dl>
50
+ <p>{{ textarea('comment') }}</p>
51
+
52
+ .. tip::
53
+
54
+ To import macros from the current file, use the special ``_self`` variable
55
+ for the source.

+ ``include``
2
+ ===========
3
+
4
+ The ``include`` statement includes a template and return the rendered content
5
+ of that file into the current namespace:
6
+
7
+ .. code-block:: jinja
8
+
9
+ {% include 'header.html' %}
10
+ Body
11
+ {% include 'footer.html' %}
12
+
13
+ Included templates have access to the variables of the active context.
14
+
15
+ If you are using the filesystem loader, the templates are looked for in the
16
+ paths defined by it.
17
+
18
+ You can add additional variables by passing them after the ``with`` keyword:
19
+
20
+ .. code-block:: jinja
21
+
22
+ {# template.html will have access to the variables from the current context and the additional ones provided #}
23
+ {% include 'template.html' with {'foo': 'bar'} %}
24
+
25
+ {% set vars = {'foo': 'bar'} %}
26
+ {% include 'template.html' with vars %}
27
+
28
+ You can disable access to the context by appending the ``only`` keyword:
29
+
30
+ .. code-block:: jinja
31
+
32
+ {# only the foo variable will be accessible #}
33
+ {% include 'template.html' with {'foo': 'bar'} only %}
34
+
35
+ .. code-block:: jinja
36
+
37
+ {# no variables will be accessible #}
38
+ {% include 'template.html' only %}
39
+
40
+ .. tip::
41
+
42
+ When including a template created by an end user, you should consider
43
+ sandboxing it. More information in the :doc:`Twig for Developers<../api>`
44
+ chapter and in the :doc:`sandbox<../tags/sandbox>` tag documentation.
45
+
46
+ The template name can be any valid Twig expression:
47
+
48
+ .. code-block:: jinja
49
+
50
+ {% include some_var %}
51
+ {% include ajax ? 'ajax.html' : 'not_ajax.html' %}
52
+
53
+ And if the expression evaluates to a ``Twig_Template`` object, Twig will use it
54
+ directly::
55
+
56
+ // {% include template %}
57
+
58
+ $template = $twig->loadTemplate('some_template.twig');
59
+
60
+ $twig->loadTemplate('template.twig')->display(array('template' => $template));
61
+
62
+ .. versionadded:: 1.2
63
+ The ``ignore missing`` feature has been added in Twig 1.2.
64
+
65
+ You can mark an include with ``ignore missing`` in which case Twig will ignore
66
+ the statement if the template to be ignored does not exist. It has to be
67
+ placed just after the template name. Here some valid examples:
68
+
69
+ .. code-block:: jinja
70
+
71
+ {% include 'sidebar.html' ignore missing %}
72
+ {% include 'sidebar.html' ignore missing with {'foo': 'bar'} %}
73
+ {% include 'sidebar.html' ignore missing only %}
74
+
75
+ .. versionadded:: 1.2
76
+ The possibility to pass an array of templates has been added in Twig 1.2.
77
+
78
+ You can also provide a list of templates that are checked for existence before
79
+ inclusion. The first template that exists will be included:
80
+
81
+ .. code-block:: jinja
82
+
83
+ {% include ['page_detailed.html', 'page.html'] %}
84
+
85
+ If ``ignore missing`` is given, it will fall back to rendering nothing if none
86
+ of the templates exist, otherwise it will throw an exception.

+ ``macro``
2
+ =========
3
+
4
+ Macros are comparable with functions in regular programming languages. They
5
+ are useful to put often used HTML idioms into reusable elements to not repeat
6
+ yourself.
7
+
8
+ Here is a small example of a macro that renders a form element:
9
+
10
+ .. code-block:: jinja
11
+
12
+ {% macro input(name, value, type, size) %}
13
+ <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
14
+ {% endmacro %}
15
+
16
+ Macros differs from native PHP functions in a few ways:
17
+
18
+ * Default argument values are defined by using the ``default`` filter in the
19
+ macro body;
20
+
21
+ * Arguments of a macro are always optional.
22
+
23
+ But as PHP functions, macros don't have access to the current template
24
+ variables.
25
+
26
+ .. tip::
27
+
28
+ You can pass the whole context as an argument by using the special
29
+ ``_context`` variable.
30
+
31
+ Macros can be defined in any template, and need to be "imported" before being
32
+ used (see the documentation for the :doc:`import<../tags/import>` tag for more
33
+ information):
34
+
35
+ .. code-block:: jinja
36
+
37
+ {% import "forms.html" as forms %}
38
+
39
+ The above ``import`` call imports the "forms.html" file (which can contain only
40
+ macros, or a template and some macros), and import the functions as items of
41
+ the ``forms`` variable.
42
+
43
+ The macro can then be called at will:
44
+
45
+ .. code-block:: jinja
46
+
47
+ <p>{{ forms.input('username') }}</p>
48
+ <p>{{ forms.input('password', null, 'password') }}</p>
49
+
50
+ If macros are defined and used in the same template, you can use the
51
+ special ``_self`` variable to import them:
52
+
53
+ .. code-block:: jinja
54
+
55
+ {% import _self as forms %}
56
+
57
+ <p>{{ forms.input('username') }}</p>
58
+
59
+ .. warning::
60
+
61
+ When you define a macro in the template where you are going to use it, you
62
+ might be tempted to call the macro directly via ``_self.input()`` instead
63
+ of importing it; even if seems to work, this is just a side-effect of the
64
+ current implementation and it won't work anymore in Twig 2.x.
65
+
66
+ When you want to use a macro in another macro from the same file, you need to
67
+ import it locally:
68
+
69
+ .. code-block:: jinja
70
+
71
+ {% macro input(name, value, type, size) %}
72
+ <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
73
+ {% endmacro %}
74
+
75
+ {% macro wrapped_input(name, value, type, size) %}
76
+ {% import _self as forms %}
77
+
78
+ <div class="field">
79
+ {{ forms.input(name, value, type, size) }}
80
+ </div>

+ ``sandbox``
2
+ ===========
3
+
4
+ The ``sandbox`` tag can be used to enable the sandboxing mode for an included
5
+ template, when sandboxing is not enabled globally for the Twig environment:
6
+
7
+ .. code-block:: jinja
8
+
9
+ {% sandbox %}
10
+ {% include 'user.html' %}
11
+ {% endsandbox %}
12
+
13
+ .. warning::
14
+
15

17

18

28

+ ``spaceless``
2
+ =============
3

4
+ Use the ``spaceless`` tag to remove whitespace *between HTML tags*, not

9
+ {% spaceless %}

+ <strong>foo</strong>
12

13
+ {% endspaceless %}
14
+
15
+ {# output will be <div><strong>foo</strong></div> #}
16
+
17
+ This tag is not meant to "optimize" the size of the generated HTML content but
18
+ merely to avoid extra whitespace between HTML tags to avoid browser rendering
19
+ quirks under some circumstances.
20
+
21
+ .. tip::
22
+
23
+ If you want to optimize the size of the generated HTML content, gzip
24
+ compress the output instead.
25
+
26
+ .. tip::
27
+
28
+ If you want to create a tag that actually removes all extra whitespace in
29
+ an HTML string, be warned that this is not as easy as it seems to be
30
+ (think of ``textarea`` or ``pre`` tags for instance). Using a third-party
31
+ library like Tidy is probably a better idea.
32
+
33
+ .. tip::
34
+
35
+ For more information on whitespace control, read the
36
+ :doc:`dedicated<../templates>` section of the documentation and learn how
37
+ you can also use the whitespace control modifier on your tags.

+ ``use``
2
+ =======
3
+
4
+ .. versionadded:: 1.1
5
+ Horizontal reuse was added in Twig 1.1.
6
+
7
+ .. note::
8
+
9
+ Horizontal reuse is an advanced Twig feature that is hardly ever needed in
10
+ regular templates. It is mainly used by projects that need to make
11
+ template blocks reusable without using inheritance.
12
+
13
+ Template inheritance is one of the most powerful Twig's feature but it is
14
+ limited to single inheritance; a template can only extend one other template.
15
+ This limitation makes template inheritance simple to understand and easy to
16
+ debug:
17
+
18
+ .. code-block:: jinja
19
+
20
+ {% extends "base.html" %}
21
+
22
+ {% block title %}{% endblock %}
23
+ {% block content %}{% endblock %}
24
+
25
+ Horizontal reuse is a way to achieve the same goal as multiple inheritance,
26
+ but without the associated complexity:
27
+
28
+ .. code-block:: jinja
29
+
30
+ {% extends "base.html" %}
31
+
32
+ {% use "blocks.html" %}
33
+
34
+ {% block title %}{% endblock %}
35
+ {% block content %}{% endblock %}
36
+
37
+ The ``use`` statement tells Twig to import the blocks defined in
38
+ ```blocks.html`` into the current template (it's like macros, but for blocks):
39
+
40
+ .. code-block:: jinja
41
+
42
+ # blocks.html
43
+ {% block sidebar %}{% endblock %}
44
+
45
+ In this example, the ``use`` statement imports the ``sidebar`` block into the
46
+ main template. The code is mostly equivalent to the following one (the
47
+ imported blocks are not outputted automatically):
48
+
49
+ .. code-block:: jinja
50
+
51
+ {% extends "base.html" %}
52
+
53
+ {% block sidebar %}{% endblock %}
54
+ {% block title %}{% endblock %}
55
+ {% block content %}{% endblock %}
56
+
57
+ .. note::
58
+
59
+ The ``use`` tag only imports a template if it does not extend another
60
+ template, if it does not define macros, and if the body is empty. But it
61
+ can *use* other templates.
62
+
63
+ .. note::
64
+
65
+ Because ``use`` statements are resolved independently of the context
66
+ passed to the template, the template reference cannot be an expression.
67
+
68
+ The main template can also override any imported block. If the template
69
+ already defines the ``sidebar`` block, then the one defined in ``blocks.html``
70
+ is ignored. To avoid name conflicts, you can rename imported blocks:
71
+
72
+ .. code-block:: jinja
73
+
74
+ {% extends "base.html" %}
75
+
76
+ {% use "blocks.html" with sidebar as base_sidebar %}
77
+
78
+ {% block sidebar %}{% endblock %}
79
+ {% block title %}{% endblock %}
80
+ {% block content %}{% endblock %}
81
+
82
+ .. versionadded:: 1.3
83
+ The ``parent()`` support was added in Twig 1.3.
84
+
85
+ The ``parent()`` function automatically determines the correct inheritance
86
+ tree, so it can be used when overriding a block defined in an imported
87
+ template:
88
+
89
+ .. code-block:: jinja
90
+
91
+ {% extends "base.html" %}
92
+
93
+ {% use "blocks.html" %}
94
+
95
+ {% block sidebar %}
96
+ {{ parent() }}
97
+ {% endblock %}
98
+
99
+ {% block title %}{% endblock %}
100
+ {% block content %}{% endblock %}
101
+
102
+ In this example, ``parent()`` will correctly call the ``sidebar`` block from
103
+ the ``blocks.html`` template.
104
+
105
+ .. tip::
106
+
107
+ In Twig 1.2, renaming allows you to simulate inheritance by calling the
108
+ "parent" block:
109
+
110
+ .. code-block:: jinja
111
+
112
+ {% extends "base.html" %}
113
+
114
+ {% use "blocks.html" with sidebar as parent_sidebar %}
115
+
116
+ {% block sidebar %}
117
+ {{ block('parent_sidebar') }}
118
+ {% endblock %}
119
+
120
+ .. note::
121
+
122
+ You can use as many ``use`` statements as you want in any given template.
123
+ If two imported templates define the same block, the latest one wins.

+ The ``verbatim`` tag was added in Twig 1.12 (it was named ``raw`` before).
6
+
7
+ The ``verbatim`` tag marks sections as being raw text that should not be
8
+ parsed. For example to put Twig syntax as example into a template you can use
9
+ this snippet:
10
+
11
+ .. code-block:: jinja
12
+
13
+ {% verbatim %}
14
+ <ul>
15
+ {% for item in seq %}
16
+ <li>{{ item }}</li>
17
+ {% endfor %}
18
+ </ul>
19
+ {% endverbatim %}
20
+
21
+ .. note::
22
+
23
+ The ``verbatim`` tag works in the exact same way as the old ``raw`` tag,
24
+ but was renamed to avoid confusion with the ``raw`` filter.

1
+ Twig for Template Designers
2
+ ===========================
3
+
4
+ This document describes the syntax and semantics of the template engine and
5
+ will be most useful as reference to those creating Twig templates.
6
+
7
+ Synopsis
8
+ --------
9
+
10
+ A template is simply a text file. It can generate any text-based format (HTML,
11
+ XML, CSV, LaTeX, etc.). It doesn't have a specific extension, ``.html`` or
12
+ ``.xml`` are just fine.
13
+
14
+ A template contains **variables** or **expressions**, which get replaced with
15
+ values when the template is evaluated, and **tags**, which control the logic
16
+ of the template.
17
+
18
+ Below is a minimal template that illustrates a few basics. We will cover the
19
+ details later on:
20
+
21
+ .. code-block:: html+jinja
22
+
23
+ <!DOCTYPE html>
24
+ <html>
25
+ <head>
26
+ <title>My Webpage</title>
27
+ </head>
28
+ <body>
29
+ <ul id="navigation">
30
+ {% for item in navigation %}
31
+ <li><a href="{{ item.href }}">{{ item.caption }}</a></li>
32
+ {% endfor %}
33
+ </ul>
34
+
35
+ <h1>My Webpage</h1>
36
+ {{ a_variable }}
37
+ </body>
38
+ </html>
39
+
40
+ There are two kinds of delimiters: ``{% ... %}`` and ``{{ ... }}``. The first
41
+ one is used to execute statements such as for-loops, the latter prints the
42
+ result of an expression to the template.
43
+
44
+ IDEs Integration
45
+ ----------------
46
+
47
+ Many IDEs support syntax highlighting and auto-completion for Twig:
48
+
49
+ * *Textmate* via the `Twig bundle`_
50
+ * *Vim* via the `Jinja syntax plugin`_
51
+ * *Netbeans* via the `Twig syntax plugin`_ (until 7.1, native as of 7.2)
52
+ * *PhpStorm* (native as of 2.1)
53
+ * *Eclipse* via the `Twig plugin`_
54
+ * *Sublime Text* via the `Twig bundle`_
55
+ * *GtkSourceView* via the `Twig language definition`_ (used by gedit and other projects)
56
+ * *Coda* and *SubEthaEdit* via the `Twig syntax mode`_
57
+ * *Coda 2* via the `other Twig syntax mode`_
58
+ * *Komodo* and *Komodo Edit* via the Twig highlight/syntax check mode
59
+ * *Notepad++* via the `Notepad++ Twig Highlighter`_
60
+ * *Emacs* via `web-mode.el`_
61
+
62
+ Variables
63
+ ---------
64
+
65
+ The application passes variables to the templates you can mess around in the
66
+ template. Variables may have attributes or elements on them you can access
67
+ too. How a variable looks like heavily depends on the application providing
68
+ those.
69
+
70
+ You can use a dot (``.``) to access attributes of a variable (methods or
71
+ properties of a PHP object, or items of a PHP array), or the so-called
72
+ "subscript" syntax (``[]``):
73
+
74
+ .. code-block:: jinja
75
+
76
+ {{ foo.bar }}
77
+ {{ foo['bar'] }}
78
+
79
+ When the attribute contains special characters (like ``-`` that would be
80
+ interpreted as the minus operator), use the ``attribute`` function instead to
81
+ access the variable attribute:
82
+
83
+ .. code-block:: jinja
84
+
85
+ {# equivalent to the non-working foo.data-foo #}
86
+ {{ attribute(foo, 'data-foo') }}
87
+
88
+ .. note::
89
+
90
+ It's important to know that the curly braces are *not* part of the
91
+ variable but the print statement. If you access variables inside tags
92
+ don't put the braces around.
93
+
94
+ If a variable or attribute does not exist, you will get back a ``null`` value
95
+ when the ``strict_variables`` option is set to ``false``, otherwise Twig will
96
+ throw an error (see :ref:`environment options<environment_options>`).
97
+
98
+ .. sidebar:: Implementation
99
+
100
+ For convenience sake ``foo.bar`` does the following things on the PHP
101
+ layer:
102
+
103
+ * check if ``foo`` is an array and ``bar`` a valid element;
104
+ * if not, and if ``foo`` is an object, check that ``bar`` is a valid property;
105
+ * if not, and if ``foo`` is an object, check that ``bar`` is a valid method
106
+ (even if ``bar`` is the constructor - use ``__construct()`` instead);
107
+ * if not, and if ``foo`` is an object, check that ``getBar`` is a valid method;
108
+ * if not, and if ``foo`` is an object, check that ``isBar`` is a valid method;
109
+ * if not, return a ``null`` value.
110
+
111
+ ``foo['bar']`` on the other hand only works with PHP arrays:
112
+
113
+ * check if ``foo`` is an array and ``bar`` a valid element;
114
+ * if not, return a ``null`` value.
115
+
116
+ .. note::
117
+
118
+ If you want to get a dynamic attribute on a variable, use the
119
+ :doc:`attribute<functions/attribute>` function instead.
120
+
121
+ Global Variables
122
+ ~~~~~~~~~~~~~~~~
123
+
124
+ The following variables are always available in templates:
125
+
126
+ * ``_self``: references the current template;
127
+ * ``_context``: references the current context;
128
+ * ``_charset``: references the current charset.
129
+
130
+ Setting Variables
131
+ ~~~~~~~~~~~~~~~~~
132
+
133
+ You can assign values to variables inside code blocks. Assignments use the
134
+ :doc:`set<tags/set>` tag:
135
+
136
+ .. code-block:: jinja
137
+
138
+ {% set foo = 'foo' %}
139
+ {% set foo = [1, 2] %}
140
+ {% set foo = {'foo': 'bar'} %}
141
+
142
+ Filters
143
+ -------
144
+
145
+ Variables can be modified by **filters**. Filters are separated from the
146
+ variable by a pipe symbol (``|``) and may have optional arguments in
147
+ parentheses. Multiple filters can be chained. The output of one filter is
148
+ applied to the next.
149
+
150
+ The following example removes all HTML tags from the ``name`` and title-cases
151
+ it:
152
+
153
+ .. code-block:: jinja
154
+
155
+ {{ name|striptags|title }}
156
+
157
+ Filters that accept arguments have parentheses around the arguments. This
158
+ example will join a list by commas:
159
+
160
+ .. code-block:: jinja
161
+
162
+ {{ list|join(', ') }}
163
+
164
+ To apply a filter on a section of code, wrap it with the
165
+ :doc:`filter<tags/filter>` tag:
166
+
167
+ .. code-block:: jinja
168
+
169
+ {% filter upper %}
170
+ This text becomes uppercase
171
+ {% endfilter %}
172
+
173
+ Go to the :doc:`filters<filters/index>` page to learn more about the built-in
174
+ filters.
175
+
176
+ Functions
177
+ ---------
178
+
179
+ Functions can be called to generate content. Functions are called by their
180
+ name followed by parentheses (``()``) and may have arguments.
181
+
182
+ For instance, the ``range`` function returns a list containing an arithmetic
183
+ progression of integers:
184
+
185
+ .. code-block:: jinja
186
+
187
+ {% for i in range(0, 3) %}
188
+ {{ i }},
189
+ {% endfor %}
190
+
191
+ Go to the :doc:`functions<functions/index>` page to learn more about the
192
+ built-in functions.
193
+
194
+ Named Arguments
195
+ ---------------
196
+
197
+ .. versionadded:: 1.12
198
+ Support for named arguments was added in Twig 1.12.
199
+
200
+ Arguments for filters and functions can also be passed as *named arguments*:
201
+
202
+ .. code-block:: jinja
203
+
204
+ {% for i in range(low=1, high=10, step=2) %}
205
+ {{ i }},
206
+ {% endfor %}
207
+
208
+ Using named arguments makes your templates more explicit about the meaning of
209
+ the values you pass as arguments:
210
+
211
+ .. code-block:: jinja
212
+
213
+ {{ data|convert_encoding('UTF-8', 'iso-2022-jp') }}
214
+
215
+ {# versus #}
216
+
217
+ {{ data|convert_encoding(from='iso-2022-jp', to='UTF-8') }}
218
+
219
+ Named arguments also allow you to skip some arguments for which you don't want
220
+ to change the default value:
221
+
222
+ .. code-block:: jinja
223
+
224
+ {# the first argument is the date format, which defaults to the global date format if null is passed #}
225
+ {{ "now"|date(null, "Europe/Paris") }}
226
+
227
+ {# or skip the format value by using a named argument for the timezone #}
228
+ {{ "now"|date(timezone="Europe/Paris") }}
229
+
230
+ You can also use both positional and named arguments in one call, which is not
231
+ recommended as it can be confusing:
232
+
233
+ .. code-block:: jinja
234
+
235
+ {# both work #}
236
+ {{ "now"|date('d/m/Y H:i', timezone="Europe/Paris") }}
237
+ {{ "now"|date(timezone="Europe/Paris", 'd/m/Y H:i') }}
238
+
239
+ .. tip::
240
+
241
+ Each function and filter documentation page has a section where the names
242
+ of all arguments are listed when supported.
243
+
244
+ Control Structure
245
+ -----------------
246
+
247
+ A control structure refers to all those things that control the flow of a
248
+ program - conditionals (i.e. ``if``/``elseif``/``else``), ``for``-loops, as
249
+ well as things like blocks. Control structures appear inside ``{% ... %}``
250
+ blocks.
251
+
252
+ For example, to display a list of users provided in a variable called
253
+ ``users``, use the :doc:`for<tags/for>` tag:
254
+
255
+ .. code-block:: jinja
256
+
257
+ <h1>Members</h1>
258
+ <ul>
259
+ {% for user in users %}
260
+ <li>{{ user.username|e }}</li>
261
+ {% endfor %}
262
+ </ul>
263
+
264
+ The :doc:`if<tags/if>` tag can be used to test an expression:
265
+
266
+ .. code-block:: jinja
267
+
268
+ {% if users|length > 0 %}
269
+ <ul>
270
+ {% for user in users %}
271
+ <li>{{ user.username|e }}</li>
272
+ {% endfor %}
273
+ </ul>
274
+ {% endif %}
275
+
276
+ Go to the :doc:`tags<tags/index>` page to learn more about the built-in tags.
277
+
278
+ Comments
279
+ --------
280
+
281
+ To comment-out part of a line in a template, use the comment syntax ``{# ...
282
+ #}``. This is useful for debugging or to add information for other template
283
+ designers or yourself:
284
+
285
+ .. code-block:: jinja
286
+
287
+ {# note: disabled template because we no longer use this
288
+ {% for user in users %}
289
+ ...
290
+ {% endfor %}
291
+ #}
292
+
293
+ Including other Templates
294
+ -------------------------
295
+
296
+ The :doc:`include<tags/include>` tag is useful to include a template and
297
+ return the rendered content of that template into the current one:
298
+
299
+ .. code-block:: jinja
300
+
301
+ {% include 'sidebar.html' %}
302
+
303
+ Per default included templates are passed the current context.
304
+
305
+ The context that is passed to the included template includes variables defined
306
+ in the template:
307
+
308
+ .. code-block:: jinja
309
+
310
+ {% for box in boxes %}
311
+ {% include "render_box.html" %}
312
+ {% endfor %}
313
+
314
+ The included template ``render_box.html`` is able to access ``box``.
315
+
316
+ The filename of the template depends on the template loader. For instance, the
317
+ ``Twig_Loader_Filesystem`` allows you to access other templates by giving the
318
+ filename. You can access templates in subdirectories with a slash:
319
+
320
+ .. code-block:: jinja
321
+
322
+ {% include "sections/articles/sidebar.html" %}
323
+
324
+ This behavior depends on the application embedding Twig.
325
+
326
+ Template Inheritance
327
+ --------------------
328
+
329
+ The most powerful part of Twig is template inheritance. Template inheritance
330
+ allows you to build a base "skeleton" template that contains all the common
331
+ elements of your site and defines **blocks** that child templates can
332
+ override.
333
+
334
+ Sounds complicated but is very basic. It's easier to understand it by
335
+ starting with an example.
336
+
337
+ Let's define a base template, ``base.html``, which defines a simple HTML
338
+ skeleton document that you might use for a simple two-column page:
339
+
340
+ .. code-block:: html+jinja
341
+
342
+ <!DOCTYPE html>
343
+ <html>
344
+ <head>
345
+ {% block head %}
346
+ <link rel="stylesheet" href="style.css" />
347
+ <title>{% block title %}{% endblock %} - My Webpage</title>
348
+ {% endblock %}
349
+ </head>
350
+ <body>
351
+ <div id="content">{% block content %}{% endblock %}</div>
352
+ <div id="footer">
353
+ {% block footer %}
354
+ &copy; Copyright 2011 by <a href="http://domain.invalid/">you</a>.
355
+ {% endblock %}
356
+ </div>
357
+ </body>
358
+ </html>
359
+
360
+ In this example, the :doc:`block<tags/block>` tags define four blocks that
361
+ child templates can fill in. All the ``block`` tag does is to tell the
362
+ template engine that a child template may override those portions of the
363
+ template.
364
+
365
+ A child template might look like this:
366
+
367
+ .. code-block:: jinja
368
+
369
+ {% extends "base.html" %}
370
+
371
+ {% block title %}Index{% endblock %}
372
+ {% block head %}
373
+ {{ parent() }}
374
+ <style type="text/css">
375
+ .important { color: #336699; }
376
+ </style>
377
+ {% endblock %}
378
+ {% block content %}
379
+ <h1>Index</h1>
380
+ <p class="important">
381
+ Welcome to my awesome homepage.
382
+ </p>
383
+ {% endblock %}
384
+
385
+ The :doc:`extends<tags/extends>` tag is the key here. It tells the template
386
+ engine that this template "extends" another template. When the template system
387
+ evaluates this template, first it locates the parent. The extends tag should
388
+ be the first tag in the template.
389
+
390
+ Note that since the child template doesn't define the ``footer`` block, the
391
+ value from the parent template is used instead.
392
+
393
+ It's possible to render the contents of the parent block by using the
394
+ :doc:`parent<functions/parent>` function. This gives back the results of the
395
+ parent block:
396
+
397
+ .. code-block:: jinja
398
+
399
+ {% block sidebar %}

406
+
407
+ The documentation page for the :doc:`extends<tags/extends>` tag describes
408
+ more advanced features like block nesting, scope, dynamic inheritance, and
409
+ conditional inheritance.
410
+
411
+ .. note::
412
+
413
+ Twig also supports multiple inheritance with the so called horizontal reuse
414
+ with the help of the :doc:`use<tags/use>` tag. This is an advanced feature
415
+ hardly ever needed in regular templates.
416
+
417
+ HTML Escaping
418
+ -------------
419
+
420
+ When generating HTML from templates, there's always a risk that a variable
421
+ will include characters that affect the resulting HTML. There are two
422
+ approaches: manually escaping each variable or automatically escaping
423
+ everything by default.
424
+
425
+ Twig supports both, automatic escaping is enabled by default.
426
+
427
+ .. note::
428
+
429
+ Automatic escaping is only supported if the *escaper* extension has been
430
+ enabled (which is the default).
431
+
432
+ Working with Manual Escaping
433
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
434
+
435
+ If manual escaping is enabled, it is **your** responsibility to escape
436
+ variables if needed. What to escape? Any variable you don't trust.
437
+
438
+ Escaping works by piping the variable through the
439
+ :doc:`escape<filters/escape>` or ``e`` filter:
440
+
441
+ .. code-block:: jinja
442
+
443
+ {{ user.username|e }}
444
+
445
+ By default, the ``escape`` filter uses the ``html`` strategy, but depending on
446
+ the escaping context, you might want to explicitly use any other available
447
+ strategies:
448
+
449
+ {{ user.username|e('js') }}
450
+ {{ user.username|e('css') }}
451
+ {{ user.username|e('url') }}
452
+ {{ user.username|e('html_attr') }}
453
+
454
+ Working with Automatic Escaping
455
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
456
+
457
+ Whether automatic escaping is enabled or not, you can mark a section of a
458
+ template to be escaped or not by using the :doc:`autoescape<tags/autoescape>`
459
+ tag:
460
+
461
+ .. code-block:: jinja
462
+
463
+ {% autoescape %}
464
+ Everything will be automatically escaped in this block (using the HTML strategy)
465
+ {% endautoescape %}
466
+
467
+ By default, auto-escaping uses the ``html`` escaping strategy. If you output
468
+ variables in other contexts, you need to explicitly escape them with the
469
+ appropriate escaping strategy:
470
+
471
+ .. code-block:: jinja
472
+
473
+ {% autoescape 'js' %}
474
+ Everything will be automatically escaped in this block (using the JS strategy)
475
+ {% endautoescape %}
476
+
477
+ Escaping
478
+ --------
479
+
480
+ It is sometimes desirable or even necessary to have Twig ignore parts it would
481
+ otherwise handle as variables or blocks. For example if the default syntax is
482
+ used and you want to use ``{{`` as raw string in the template and not start a
483
+ variable you have to use a trick.
484
+
485
+ The easiest way is to output the variable delimiter (``{{``) by using a variable
486
+ expression:
487
+
488
+ .. code-block:: jinja
489
+
490
+ {{ '{{' }}
491
+
492
+ For bigger sections it makes sense to mark a block
493
+ :doc:`verbatim<tags/verbatim>`.
494
+
495
+ Macros
496
+ ------
497
+
498
+ .. versionadded:: 1.12
499
+ Support for default argument values was added in Twig 1.12.
500
+
501
+ Macros are comparable with functions in regular programming languages. They
502
+ are useful to reuse often used HTML fragments to not repeat yourself.
503
+
504
+ A macro is defined via the :doc:`macro<tags/macro>` tag. Here is a small example
505
+ (subsequently called ``forms.html``) of a macro that renders a form element:
506
+
507
+ .. code-block:: jinja
508
+
509
+ {% macro input(name, value, type, size) %}
510
+ <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
511
+ {% endmacro %}
512
+
513
+ Macros can be defined in any template, and need to be "imported" via the
514
+ :doc:`import<tags/import>` tag before being used:
515
+
516
+ .. code-block:: jinja
517
+
518
+ {% import "forms.html" as forms %}
519
+
520
+ <p>{{ forms.input('username') }}</p>
521
+
522
+ Alternatively, you can import individual macro names from a template into the
523
+ current namespace via the :doc:`from<tags/from>` tag and optionally alias them:
524
+
525
+ .. code-block:: jinja
526
+
527
+ {% from 'forms.html' import input as input_field %}
528
+
529
+ <dl>
530
+ <dt>Username</dt>
531
+ <dd>{{ input_field('username') }}</dd>
532
+ <dt>Password</dt>
533
+ <dd>{{ input_field('password', '', 'password') }}</dd>
534
+ </dl>
535
+
536
+ A default value can also be defined for macro arguments when not provided in a
537
+ macro call:
538
+
539
+ .. code-block:: jinja
540
+
541
+ {% macro input(name, value = "", type = "text", size = 20) %}
542
+ <input type="{{ type }}" name="{{ name }}" value="{{ value|e }}" size="{{ size }}" />
543
+ {% endmacro %}
544
+
545
+ Expressions
546
+ -----------
547
+
548
+ Twig allows expressions everywhere. These work very similar to regular PHP and
549
+ even if you're not working with PHP you should feel comfortable with it.
550
+
551
+ .. note::
552
+
553
+ The operator precedence is as follows, with the lowest-precedence
554
+ operators listed first: ``b-and``, ``b-xor``, ``b-or``, ``or``, ``and``,
555
+ ``==``, ``!=``, ``<``, ``>``, ``>=``, ``<=``, ``in``, ``..``, ``+``,
556
+ ``-``, ``~``, ``*``, ``/``, ``//``, ``%``, ``is``, and ``**``.
557
+
558
+ Literals
559
+ ~~~~~~~~
560
+
561
+ .. versionadded:: 1.5
562
+ Support for hash keys as names and expressions was added in Twig 1.5.
563
+
564
+ The simplest form of expressions are literals. Literals are representations
565
+ for PHP types such as strings, numbers, and arrays. The following literals
566
+ exist:
567
+
568
+ * ``"Hello World"``: Everything between two double or single quotes is a
569
+ string. They are useful whenever you need a string in the template (for
570
+ example as arguments to function calls, filters or just to extend or
571
+ include a template).
572
+
573
+ * ``42`` / ``42.23``: Integers and floating point numbers are created by just
574
+ writing the number down. If a dot is present the number is a float,
575
+ otherwise an integer.
576
+
577
+ * ``["foo", "bar"]``: Arrays are defined by a sequence of expressions
578
+ separated by a comma (``,``) and wrapped with squared brackets (``[]``).
579
+
580
+ * ``{"foo": "bar"}``: Hashes are defined by a list of keys and values
581
+ separated by a comma (``,``) and wrapped with curly braces (``{}``):
582
+
583
+ .. code-block:: jinja
584
+
585
+ {# keys as string #}
586
+ { 'foo': 'foo', 'bar': 'bar' }
587
+
588
+ {# keys as names (equivalent to the previous hash) -- as of Twig 1.5 #}
589
+ { foo: 'foo', bar: 'bar' }
590
+
591
+ {# keys as integer #}
592
+ { 2: 'foo', 4: 'bar' }
593
+
594
+ {# keys as expressions (the expression must be enclosed into parentheses) -- as of Twig 1.5 #}
595
+ { (1 + 1): 'foo', (a ~ 'b'): 'bar' }
596
+
597
+ * ``true`` / ``false``: ``true`` represents the true value, ``false``
598
+ represents the false value.
599
+
600
+ * ``null``: ``null`` represents no specific value. This is the value returned
601
+ when a variable does not exist. ``none`` is an alias for ``null``.
602
+
603
+ Arrays and hashes can be nested:
604
+
605
+ .. code-block:: jinja
606
+
607
+ {% set foo = [1, {"foo": "bar"}] %}
608
+
609
+ .. tip::
610
+
611
+ Using double-quoted or single-quoted strings has no impact on performance
612
+ but string interpolation is only supported in double-quoted strings.
613
+
614
+ Math
615
+ ~~~~
616
+
617
+ Twig allows you to calculate with values. This is rarely useful in templates
618
+ but exists for completeness' sake. The following operators are supported:
619
+
620
+ * ``+``: Adds two objects together (the operands are casted to numbers). ``{{
621
+ 1 + 1 }}`` is ``2``.
622
+
623
+ * ``-``: Subtracts the second number from the first one. ``{{ 3 - 2 }}`` is
624
+ ``1``.
625
+
626
+ * ``/``: Divides two numbers. The returned value will be a floating point
627
+ number. ``{{ 1 / 2 }}`` is ``{{ 0.5 }}``.
628
+
629
+ * ``%``: Calculates the remainder of an integer division. ``{{ 11 % 7 }}`` is
630
+ ``4``.
631
+
632
+ * ``//``: Divides two numbers and returns the truncated integer result. ``{{
633
+ 20 // 7 }}`` is ``2``.
634
+
635
+ * ``*``: Multiplies the left operand with the right one. ``{{ 2 * 2 }}`` would
636
+ return ``4``.
637
+
638
+ * ``**``: Raises the left operand to the power of the right operand. ``{{ 2 **
639
+ 3 }}`` would return ``8``.
640
+
641
+ Logic
642
+ ~~~~~
643
+
644
+ You can combine multiple expressions with the following operators:
645
+
646
+ * ``and``: Returns true if the left and the right operands are both true.
647
+
648
+ * ``or``: Returns true if the left or the right operand is true.
649
+
650
+ * ``not``: Negates a statement.
651
+
652
+ * ``(expr)``: Groups an expression.
653
+
654
+ .. note::
655
+
656
+ Twig also support bitwise operators (``b-and``, ``b-xor``, and ``b-or``).
657
+
658
+ Comparisons
659
+ ~~~~~~~~~~~
660
+
661
+ The following comparison operators are supported in any expression: ``==``,
662
+ ``!=``, ``<``, ``>``, ``>=``, and ``<=``.
663
+
664
+ Containment Operator
665
+ ~~~~~~~~~~~~~~~~~~~~
666
+
667
+ The ``in`` operator performs containment test.
668
+
669
+ It returns ``true`` if the left operand is contained in the right:
670
+
671
+ .. code-block:: jinja
672
+
673
+ {# returns true #}
674
+
675
+ {{ 1 in [1, 2, 3] }}
676
+
677
+ {{ 'cd' in 'abcde' }}
678
+
679
+ .. tip::
680
+
681
+ You can use this filter to perform a containment test on strings, arrays,
682
+ or objects implementing the ``Traversable`` interface.
683
+
684
+ To perform a negative test, use the ``not in`` operator:
685
+
686
+ .. code-block:: jinja
687
+
688
+ {% if 1 not in [1, 2, 3] %}
689
+
690
+ {# is equivalent to #}
691
+ {% if not (1 in [1, 2, 3]) %}
692
+
693
+ Test Operator
694
+ ~~~~~~~~~~~~~
695
+
696
+ The ``is`` operator performs tests. Tests can be used to test a variable against
697
+ a common expression. The right operand is name of the test:
698
+
699
+ .. code-block:: jinja
700
+
701
+ {# find out if a variable is odd #}
702
+
703
+ {{ name is odd }}
704
+
705
+ Tests can accept arguments too:
706
+
707
+ .. code-block:: jinja
708
+
709
+ {% if loop.index is divisibleby(3) %}
710
+
711
+ Tests can be negated by using the ``is not`` operator:
712
+
713
+ .. code-block:: jinja
714
+
715
+ {% if loop.index is not divisibleby(3) %}
716
+
717
+ {# is equivalent to #}
718
+ {% if not (loop.index is divisibleby(3)) %}
719
+
720
+ Go to the :doc:`tests<tests/index>` page to learn more about the built-in
721
+ tests.
722
+
723
+ Other Operators
724
+ ~~~~~~~~~~~~~~~
725
+
726
+ .. versionadded:: 1.12.0
727
+ Support for the extended ternary operator was added in Twig 1.12.0.
728
+
729
+ The following operators are very useful but don't fit into any of the other
730
+ categories:
731
+
732
+ * ``..``: Creates a sequence based on the operand before and after the
733
+ operator (this is just syntactic sugar for the :doc:`range<functions/range>`
734
+ function).
735
+
736
+ * ``|``: Applies a filter.
737
+
738
+ * ``~``: Converts all operands into strings and concatenates them. ``{{ "Hello
739
+ " ~ name ~ "!" }}`` would return (assuming ``name`` is ``'John'``) ``Hello
740
+ John!``.
741
+
742
+ * ``.``, ``[]``: Gets an attribute of an object.
743
+
744
+ * ``?:``: The ternary operator:
745
+
746
+ .. code-block:: jinja
747
+
748
+ {{ foo ? 'yes' : 'no' }}
749
+
750
+ {# as of Twig 1.12.0 #}
751
+ {{ foo ?: 'no' }} == {{ foo ? foo : 'no' }}
752
+ {{ foo ? 'yes' }} == {{ foo ? 'yes' : '' }}
753
+
754
+ String Interpolation
755
+ ~~~~~~~~~~~~~~~~~~~~
756
+
757
+ .. versionadded:: 1.5
758
+ String interpolation was added in Twig 1.5.
759
+
760
+ String interpolation (`#{expression}`) allows any valid expression to appear
761
+ within a *double-quoted string*. The result of evaluating that expression is
762
+ inserted into the string:
763
+
764
+ .. code-block:: jinja
765
+
766
+ {{ "foo #{bar} baz" }}
767
+ {{ "foo #{1 + 2} baz" }}
768
+
769
+ Whitespace Control
770
+ ------------------
771
+
772
+ .. versionadded:: 1.1
773
+ Tag level whitespace control was added in Twig 1.1.
774
+
775
+ The first newline after a template tag is removed automatically (like in PHP.)
776
+ Whitespace is not further modified by the template engine, so each whitespace
777
+ (spaces, tabs, newlines etc.) is returned unchanged.
778
+
779
+ Use the ``spaceless`` tag to remove whitespace *between HTML tags*:
780
+
781
+ .. code-block:: jinja
782
+
783
+ {% spaceless %}
784
+ <div>
785
+ <strong>foo</strong>
786
+ </div>
787
+ {% endspaceless %}
788
+
789
+ {# output will be <div><strong>foo</strong></div> #}
790
+
791
+ In addition to the spaceless tag you can also control whitespace on a per tag
792
+ level. By using the whitespace control modifier on your tags, you can trim
793
+ leading and or trailing whitespace:
794
+
795
+ .. code-block:: jinja
796
+
797
+ {% set value = 'no spaces' %}
798
+ {#- No leading/trailing whitespace -#}
799
+ {%- if true -%}
800
+ {{- value -}}
801
+ {%- endif -%}
802
+
803
+ {# output 'no spaces' #}
804
+
805
+ The above sample shows the default whitespace control modifier, and how you can
806
+ use it to remove whitespace around tags. Trimming space will consume all whitespace
807
+ for that side of the tag. It is possible to use whitespace trimming on one side
808
+ of a tag:
809
+
810
+ .. code-block:: jinja
811
+
812
+ {% set value = 'no spaces' %}
813
+ <li> {{- value }} </li>
814
+
815
+ {# outputs '<li>no spaces </li>' #}
816
+
817
+ Extensions
818
+ ----------
819
+
820
+ Twig can be easily extended.
821
+
822
+ If you are looking for new tags, filters, or functions, have a look at the Twig official
823
+ `extension repository`_.
824
+
825
+ If you want to create your own, read the :ref:`Creating an
826

13

15
+ * This exception class and its children must only be used when
16
+ * an error occurs during the loading of a template, when a syntax error
17
+ * is detected in a template, or when rendering a template. Other
18
+ * errors must use regular PHP exception classes (like when the template
19

20

21
+ * To help debugging template issues, this class tracks the original template
22
+ * name and line where the error occurred.
23
+ *
24
+ * Whenever possible, you must set these information (original template name
25
+ * and line number) yourself by passing them to the constructor. If some or all
26
+ * these information are not available from where you throw the exception, then
27
+ * this class will guess them automatically (when the line number is set to -1
28
+ * and/or the filename is set to null). As this is a costly operation, this
29

30
