+ === PHP Code Widget ===
2
+ Contributors: Otto

+ Donate link: https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=otto%40ottodestruct%2ecom
4
+ Tags: php, widget, execphp
5
+ Requires at least: 2.5
6
+ Tested up to: 2.8
7
+ Stable tag: 1.2
8
+
9
+ Like the Text widget, but also allows working PHP code to be inserted.
10
+
11
+ == Description ==
12
+
13
+ The normal Text widget allows you to insert arbitrary Text and/or HTML code.
14
+ This allows that too, but also parses any inserted PHP code and executes it.
15
+ This makes it easier to migrate to a widget-based theme.
16
+
17
+ All PHP code must be enclosed in the standard <?php and ?> tags for it to be
18
+ recognized.
19
+
20
+ == Installation ==
21
+
22
+ 1. Upload `execphp.php` to the `/wp-content/plugins/` directory
23
+ 1. Activate the plugin through the 'Plugins' menu in WordPress
24
+ 1. Use the widget like any other widget.
25
+
26
+ == Frequently Asked Questions ==
27
+
28
+ = There's some kind of error on line 37! =
29
+
30
+ That error means that your PHP code is incorrect or otherwise broken.
31
+
32
+ = No, my code is fine! =
33
+
34
+ No, it's not.
35
+
36
+ Really.
37
+
38
+ This widget has no bugs, it's about the simplest widget one can possibly
39
+ make. Any errors coming out of the "execphp,php" file are errors in code you
40
+ put into one of the widgets. The reason that it shows the error being in the
41
+ execphp.php file is because that is where your code is actually being run
42
+ from.
43
+
44
+ So, if it says that you have an error on line 27, I assure you, the problem
45
+ is yours. Please don't email me about that error.
46
+
47
+ == Screenshots ==
48
+
49
+ 1. The widgets screen showing two PHP code widgets in use.
