Returning content to the client

Raw wikitext content

This function returns the raw content specified in $text, it can be callled any time from extension-setup or after. If the $save parameter is supplied it will bring up a download dialog with teh default name set to $save, otherwise it will download and open unprompted. If $expand is set to true, then any templates, parser-functions or variables in the content will be expanded.

Domain-based default redirect

If no page title is specified, redirect to a default depending on the domain name in the requested URL. In this example requests to abc.org or any of it's subdomains with no title specified will redirect to the Welcome to ABC article, and any requests to the exact domain of www.xyz.org without a title end up at the XYZ Home article. Titleless requests to any other domain which resolves to this example wiki will be unaffected and left to the rest of the configuration to deal with. This code should be executed early in the LocalSettings before any extensions are included, but after $wgServer is defined.

examineBraces

This function returns an array of the brace structure found in the passed wikitext parameter.

') {

$brace =& $braces[$depths[$depth-1]]; $brace[LENGTH] = $match[0][1]-$brace[OFFSET]+2; $brace[DEPTH] = $depth--; } else { $depths[$depth++] = count($braces); $braces[] = array( NAME => $match[1][0], OFFSET => $match[0][1] ); } } return $braces; } </php>}}

The following input,

foo{{#bar:baz|biz{{foo|shmoo}}}}{{moo}}baz

Gives the following array:

Array( [0] => Array( [NAME] => #bar [OFFSET] => 3 [LENGTH] => 29 [DEPTH] => 1 ) [1] => Array( [NAME] => foo [OFFSET] => 17 [LENGTH] => 13 [DEPTH] => 2 ) [2] => Array( [NAME] => moo [OFFSET] => 32 [LENGTH] => 7 [DEPTH] => 1 ) )

Wikitext in Sidebar

<php> global $wgUser,$wgTitle,$wgParser; $side = new Article(Title::newFromText('MediaWiki:Sidebar')); if (is_object($wgParser)) { $psr = $wgParser; $opt = $wgParser->mOptions; } else { $psr = new Parser; $opt = NULL; } if (!is_object($opt)) $opt = ParserOptions::newFromUser($wgUser); $html = $psr->parse($side->fetchContent(),$wgTitle,$opt,true,true)->getText();

echo preg_replace("/

\\s*<\\/li>/",,$html); </php>
