>>Tested with: WikkaWiki version **1.1.6.4**
Example: [[DescentiaPedia:DescentiaPedia | DescentiaPedia]]>>=====Comments Clip in the Footer=====
CommentsClipFooter is the name of an action I included in the footer of [[www.prepare4descent.net/DescentiaPedia | DescentiaPedia]]. I made some changes from the original code (recentcomments.php... or was it recentlycommented.php???) in order to work this into the footer, and to style this to match ""DescentiaPedia"". I have not tested this to see if it can be still used in a page. Nor have I tested this in any version of wikka other than 1.1.6.4. Here is the code:
%%(php;1;commentsclipft.php)
<?php
/**
* Display a list of recent comments.
*
* @package Actions
* @name CommentsClipFooter
*
* @author {@link http://wikkawiki.org/DarTar Dario Taraborelli} (preliminary code cleanup)
* @author {@link http://wikkawiki.org/NickDamoulakis Nick Damoulakis} (ACL check)
* @author {@link http://wikkawiki.org/WillyP WillyP} (minor hack to match 'changesclipft' style, and to be able to use this in a footer. Added COMMENT_QTY, more link)
* @since
*
* @input none
* Tested with 1.1.6.4, in the footer only.
