1. Extension:WikiaInfo

These are the MediaWiki extensions we're using and/or developing. Please refer to the information on the mediawiki.org wiki for installation and usage details. Extensions here which have no corresponding mediawiki article are either not ready for use or have been superseded. You can also browse our extension code in our local Subversion repository or our GitHub mirror.

1. Define a new class based on the SpecialPage class

# Override SpecialPage::execute() function execute() { global $wgOut; $this->setHeaders(); $wgOut->addWikiText("=== Currently Installed Wikia ===\n");

# Get list of domain symlinks by inode $domains = array(); $dir = $GLOBALS['domains']; $handle = opendir($dir); while (false !== ($link = readdir($handle))) { if (!ereg('^\\.',$link)) { $stat = stat("$dir/$link"); $inode = $stat[1]; if (is_array($domains[$inode])) $domains[$inode][] = $link; else $domains[$inode] = array($link); } } closedir($handle);

# Render the list (don't show naked domains if a www also exists)

$table = "

openlevels=1\n";

foreach ($wikia as $file => $domains) { if (is_array($domains)) { $stat = stat("$dir/$file/wiki"); $ver = $codebases[$stat[1]]; $table .= "*$file ($ver)\n"; $table .= "**LocalSettings.php\n"; sort($domains); foreach ($domains as $domain) if (!in_array("www.$domain",$domains)) { $wiki = "http://$domain/wiki/index.php?title"; $table .= "**$domain\n"; $table .= "***[$wiki=Special:Recentchanges Recent changes]\n"; $table .= "***[$wiki=Special:Version Version]\n"; $table .= "***[$wiki=Special:Statistics Statistics]\n"; } } } $table .= "

$wgOut->addWikiText($table);

}

1. Called from $wgExtensionFunctions array when initialising extensions

function wfSetupWikiaInfo() { global $wgLanguageCode,$wgMessageCache; $wgMessageCache->addMessages(array('wikiainfo' => 'Current Wikia Information')); SpecialPage::addPage(new SpecialWikiaInfo()); } ?>
