First attempt at providing Wowhead item links. Please post any bugs or weirdness. This requires BBPress 1.0 RC 3+ and PHP 5+ . It has no cache, so may not be suited to ultra-high volume forums.

/*

Plugin Name: Simple Wowhead Item Links

Plugin Description: Adds item sudo-html to create links to Wowhead.

Author: Tim Howgego

Author URI: http://timhowgego.com/

Version: 0.1.rc

*/



/*

Requirements:



* PHP 5 or above.

* BBPress 1.0 RC3 or above.



Install:



* Copy the file to the "my-plugins" directory.

* Active the plugin within the Admin interface.



Customising:



* Default language is English. For other languages, edit $lang (in bb_wowhead_item_search) below.

* Default will color items which are uncommon or rarer. To change this edit $commonest_color (in bb_wowhead_item_search) below.



Using:



* Users must enter the following "sudo-HTML" code within their posts: <item>Name</item> - where name is the correct name of the item to be linked to.

* Wowhead is queried each time a new link is posted. Once the link is created, it is stored as a complete link within the post. A cache should not be required given the amount of traffic on most forums.

* If Wowhead is unavailable (often due to maintenance), or some other error occurs, the link created will simply point to a Wowhead search for the item.



Thanks Drexle for some ideas.
