    You have installed your own Mediawiki engine and you are hosting (have imported) more than one (former) Wikis on/into it, becoming a so called Wikihive or Wikifarm. So you have pages sorted like Somewiki/Fnord, Somewiki/Foobar and now the users of Somewiki are asking for their own Recent Changes page that only includes the pages of their (sub)-wiki, so a subset of your complete RC page that only shows pages beggining with the string "Somewiki" in this case. (Another approach would have been sorting out by categories,but this would have meant having to look inside page content instead of doing it inside a SELECT statement).

    So i read Write your own MediaWiki extension and came up with this code:

    <customrc> Tag[edit]

    Users can just insert a tag like <customrc>Whatever</customrc> into any wiki page and will include a Recent changes table of all pages beginning with "Whatever". Normally they would insert this into index.php/Subwiki/RecentChanges then.


    Compare S23Wiki:Debian/RecentChanges with its source.

    Custom Recent Changes Extension[edit]

     # Custom RC-page WikiMedia extension
     # display custom recent changes pages for a subset of pages inside any wiki page
     # insert <customrc>Fnord<customrc> into a wikipage and it will be replaced
     # by a table containing stripped RecentChanges for all pages begging with "Fnord".
     # This is made for making RC pages for "subwikis" on a "wikihive" where all pages
     # below a /Subwiki page should be taken into account. like yourwiki/subwiki/RecentChanges.
