11	+ == Description ==
12	+
13	+ <h3>Wunderground is the best weather site.</h3>
14	+
15	+ __All your weather are belong to us!__ Wunderground.com has the most accurate and in-depth weather information. They're also not evil corporate giants, and are weather geeks, which is nice.
16	+
17	+ This plugin uses the Wunderground API to gather its accurate forcasts.
18	+
19	+
20	+ <h3>If you want a great-looking weather forecast, use this plugin.</h3>
21	+ __This is the best-looking weather forecast plugin for WordPress.__ It looks great on many different templates out of the box, including the default WP theme, TwentyTen.
22	+
23	+ The WP Wunderground plugin uses 10 great-looking icon sets from Wunderground.com, including:
24	+
25	+ * <a href="http://icons-ecast.wxug.com/i/c/a/clear.gif" target="_blank" rel="nofollow">Default</a>
26	+ * <a href="http://icons-ecast.wxug.com/i/c/b/clear.gif" target="_blank" rel="nofollow">Smiley</a>
27	+ * <a href="http://icons-ecast.wxug.com/i/c/c/clear.gif" target="_blank" rel="nofollow">Generic</a>

37	+
38	+ <h3>Using the WP Wunderground Weather Plugin</h3>
39	+ The plugin can be configured in two ways:
40	+
41	+ 1. Configure the plugin in the admin's WP Wunderground settings page, then add `[forecast]` to your content where you want the forecast to appear.
42	+ 2. Go crazy with the `[forecast]` shortcode.
43	+
44	+ <h4>Using the `[forecast]` Shortcode</h4>
45	+ If you're a maniac for shortcodes, and you want all control all the time, this is a good way to use it.
46	+
47	+ `[forecast location="Tokyo, Japan" caption="Weather for Tokyo" measurement='F' todaylabel="Today" datelabel="date('m/d/Y')" highlow='%%high%%°/%%low%%°' numdays="3" iconset="Cartoon" class="css_table_class"]`
48	+
49	+ <strong>The shortcode supports the following settings:</strong>
50	+
51	+ * `location="Tokyo, Japan"` - Use any city/state combo or US/Canada ZIP code
52	+ * `caption="Weather for Tokyo"` - Add a caption to your table (it's like a title)
53	+ * `measurement='F'` - Choose Fahrenheit or Celsius by using "F" or "C"
54	+ * `datelabel="date('m/d/Y')"` - Format the way the days display ("9/30/2012" in this example)
55	+ * `todaylabel="Today"` - Format how today's date appears ("Today" in this example)
56	+ * `highlow='%%high%%°/%%low%%°'` - Format how the highs & low temps display ("85°/35°" in this example)
57	+ * `numdays=3` - Change the number of days displayed in the forecast. Up to 6 day forecast.
58	+ * `iconset="Cartoon"` - Choose your iconset from one of 10 great options
59	+ * `class="css_table_class"` - Change the CSS class of the generated forecast table
60	+

83	+
84	+ = I want to modify the forecast output. How do I do that? =
85	+
86	+ <pre>
87	+ function replace_weather($content) {
88	+ $content = str_replace('Rain', 'RAYNNNNN!', $content);
89	+ $content = str_replace('Snow', 'SNNNOOOO!', $content);
90	+ return $content;
91	+ }
92	+ add_filter('wp_wunderground_forecast', 'replace_weather');
93	+ </pre>
94	+
95	+ = What is the plugin license? =
96	+
97	+ * This plugin is released under a GPL license.
98	+
99	+ = Do I need a Wunderground account? =
100	+ Nope, no account needed.
101	+
102	+ = This plugin slows down my site. =
103	+ It is recommended to use a caching plugin (such as WP Super Cache) with this plugin; that way the forecast isn't re-loaded every page load.
104	+
105	+ = Why would I want this plugin? =
106	+ This plugin is a perfect compliment for regional websites (about a city or town), personal websites where you want to share what the weather is like where you're blogging from, travel sites (show the weather at each stop!), <a href="http://www.denversnowremovalservice.com">snow removal</a> websites, yard services websites, and more.

255	+ <h4>Adding the Forecast to your Content</h4>
256	+ <p class="howto updated" style="padding:1em;">If you configure the settings to the left, all you will need to do is add <code>[forecast]</code> to your post or page content or text widget to add the forecast table.</p>
257	+ <h4>Date Formatting</h4>
258	+ <p>You can use the following tags: <code>%%weekday%%</code>, <code>%%day%%</code>, <code>%%month%%</code>, <code>%%year%%</code>, as well as using <a href="http://www.php.net/manual/en/function.date.php" target="_blank">PHP date formatting</a>.</p>
259	+ <h4>Example date options:</h4>
260	+ <ul>
261	+ <li><code>Today's Weather (%%weekday%%)</code> <em>outputs as: </em> <strong>Today's Weather ($weekday)</strong></li>
262	+ <li><code>%%day%%<strong>/</strong>%%month%%<strong>/</strong>%%year%% Weather</code> <em>outputs as: </em> <strong>$date Weather</strong></li>
263	+ <li><code>Weather on date("m/d/Y")</code> <em>outputs as: </em> <strong>Weather on $date</strong></li>
264	+ <li><code>date("\W\e\a\\t\h\e\\r\ \\f\o\\r\ m-d-y")</code> <em>outputs as: </em> <strong>Weather for $date2</strong></li>
265	+ </ul>
266	+ <hr style="padding-top:1em; outline:none; border:none; border-bottom:1px solid #ccc;"/>
267	+ <h4>Highs & Lows Formatting</h4>
268	+ <p>Use the following tags to modify how low and high temps display: <code>%%high%%</code> and <code>%%low%%</code>.</p>
269	+ <ul>
270	+ <li><strong>HTML is fully supported. This allows you to color-code:</strong><br /><code><span style="color:red;">%%high%%</span>/<span style="color:blue;">%%low%%</span></code> <em>outputs as: </em> <span style="color:red;">85</span>/<span style="color:blue;">55</span></li>
271	+ <li><strong>Choose to only show high or low:</strong><br /><code>High of %%high%%.</code> <em>outputs as: </em> High of 85.</li>
272	+ <li><strong>Use CSS classes too:</strong><br /><code><div class="temp">High of <span class="temphigh">%%high%%</span><br />Low of <span class="templow">%%low%%</span></div></code> <em>outputs as: </em> <div class="temp">High of <span class="temphigh">85</span><br />Low of <span class="templow">55</span></div></li>
273	+ </ul>
274	+ <hr style="padding-top:1em; outline:none; border:none; border-bottom:1px solid #ccc;"/>
275	+
276	+ <h4>Using the <code>[forecast]</code> Shortcode</h4>
277	+
278	+ <p>If you're a maniac for shortcodes, and you want all control all the time, this is a good way to use it.</p>
279	+
280	+ <p><code>[forecast location="Tokyo, Japan" caption="Weather for Tokyo" measurement='F' todaylabel="Today" datelabel="date('m/d/Y')" highlow='%%high%%°/%%low%%°' numdays="3" iconset="Cartoon" class="css_table_class"]</code></p>
281	+
282	+ <p><strong>The shortcode supports the following settings:</strong></p>
283	+ <ul>
284	+ <li><code>location="Tokyo, Japan"</code> - Use any city/state combo or US/Canada ZIP code
285	+ </li><li><code>caption="Weather for Tokyo"</code> - Add a caption to your table (it's like a title)
286	+ </li><li><code>measurement='F'</code> - Choose Fahrenheit or Celsius by using "F" or "C"
287	+ </li><li><code>datelabel="date('m/d/Y')"</code> - Format the way the days display ("9/30/2012" in this example)
288	+ </li><li><code>todaylabel="Today"</code> - Format how today's date appears ("Today" in this example)
289	+ </li><li><code>highlow='%%high%%°/%%low%%°'</code> - Format how the highs & low temps display ("85°/35°" in this example)
290	+ </li><li><code>numdays=3</code> - Change the number of days displayed in the forecast. Up to 6 day forecast.
291	+ </li><li><code>iconset="Cartoon"</code> - Choose your iconset from one of 10 great options
292	+ </li><li><code>class="css_table_class"</code> - Change the CSS class of the generated forecast table
