This is a hacked version of Extension:DynamicPageList that produces forum-style output. Uses <forum> instead of <DynamicPageList>, so both extensions can coexist on a single wiki.
Added features:
- addlastedit=true (Displays the time each page was last edited. If mode=table, this will be placed in its own cell.)
- addlasteditor=true (Displays the last editor of the page. If mode=table, this will be placed in its own cell.)
- cache=false (Disables the page cache for dynamic results.)
- historylink=show (Appends a history link to the last edit.)
-
- historylink=embed (Links the last edit to the page history.)
- mode=table (Each link is in its own row. <table> tags are NOT produced by the <forum> element, so multiple instances can be in the same table; the forum elements have to be put inside a HTML table element)
- newdays={number} (Marks all pages edited less than {number} days ago with class="forum_new".)
- ordermethod=pageid (Orders by the page id, so the most recently created topics are on top.)
- start={number} (Starts at the {n+1}th topic of the forum, so large forums can occupy multiple pages.)
- timestamp=true (Adds a timestamp to the end of each URL, so newly edited versions won't show up in the browser history.)
- title={string} (Sets the page link as the given title, and sets count=1. Used for linking to subforums.)
This extension has been tested on MediaWiki 1.5.6 and above. Most of the original DynamicPageList functionality has been preserved, although many defaults must be overridden to use the original format.
