Notes

The following contents are based on index.php from MediaWiki (I'm not sure which version, but probably later than 1.7.1). Some code may be redundant, but I was trying to make the fewest possible changes in order to avoid breaking anything. It's currently in use as the front page for Outside Life, a webcomic.

  • /
  1. Initialise common code

require_once( './includes/WebStart.php' );

  1. Initialize MediaWiki base class

require_once( "includes/Wiki.php" ); $mediaWiki = new MediaWiki();

wfProfileIn( 'main-misc-setup' ); OutputPage::setEncodings(); # Not really used yet

$maxLag = $wgRequest->getVal( 'maxlag' ); if ( !is_null( $maxLag ) ) { if ( !$mediaWiki->checkMaxLag( $maxLag ) ) { exit; } }

  1. Query string fields

//$action = $wgRequest->getVal( 'action', 'view' ); //$title = $wgRequest->getVal( 'title' );

//$wgTitle = $mediaWiki->checkInitialQueries( $title,$action,$wgOut, $wgRequest, $wgContLang ); $wgTitle = Title::newFromURL( $title ); if ($wgTitle == NULL) { unset( $wgTitle ); }

  2. Send Ajax requests to the Ajax dispatcher.

/* if ( $wgUseAjax && $action == 'ajax' ) { require_once( $IP . '/includes/AjaxDispatcher.php' );

$dispatcher = new AjaxDispatcher(); $dispatcher->performAction(); $mediaWiki->restInPeace( $wgLoadBalancer ); exit; }

  • /

wfProfileOut( 'main-misc-setup' );

  1. Setting global variables in mediaWiki

$mediaWiki->setVal( 'Server', $wgServer ); $mediaWiki->setVal( 'DisableInternalSearch', $wgDisableInternalSearch ); $mediaWiki->setVal( 'action', $action ); $mediaWiki->setVal( 'SquidMaxage', $wgSquidMaxage ); $mediaWiki->setVal( 'EnableDublinCoreRdf', $wgEnableDublinCoreRdf ); $mediaWiki->setVal( 'EnableCreativeCommonsRdf', $wgEnableCreativeCommonsRdf ); $mediaWiki->setVal( 'CommandLineMode', $wgCommandLineMode ); $mediaWiki->setVal( 'UseExternalEditor', $wgUseExternalEditor ); $mediaWiki->setVal( 'DisabledActions', $wgDisabledActions );

$wgArticle = $mediaWiki->initialize ( $wgTitle, $wgOut, $wgUser, $wgRequest ); $mediaWiki->finalCleanup ( $wgDeferredUpdateList, $wgLoadBalancer, $wgOut );

  1. Not sure when $wgPostCommitUpdateList gets set, so I keep this separate from finalCleanup

$mediaWiki->doUpdates( $wgPostCommitUpdateList );

$mediaWiki->restInPeace( $wgLoadBalancer ); </php>
