Tested with: WikkaWiki version 1.1.6.4
Example: DescentiaPedia
CommentsClipFooter is the name of an action I included in the footer of 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:
commentsclipft.php (line 1)
  1. <?php
  2. /**
  3.  * Display a list of recent comments.
  4.  *
  5.  * @package     Actions
  6.  * @name            CommentsClipFooter
  7.  *
  8.  * @author      {@link http://wikkawiki.org/DarTar Dario Taraborelli} (preliminary code cleanup)
  9.  * @author      {@link http://wikkawiki.org/NickDamoulakis Nick Damoulakis} (ACL check)
  10.  * @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)
  11.  * @since      
  12.  *
  13.  * @input       none
  14.  * Tested with 1.1.6.4, in the footer only.
