Legacy.svg Legacy: This article describes a concept that has been superseded in the course of ongoing development on the Organic Design wiki. Please do not develop this any further or base work on this concept, this is only useful for a historic record of work done. You may find a link to the currently used concept or function in this article, if not you can contact the author to find out what has taken the place of this legacy item.

  1. Keep track of JavaScript added to page to avoid doubleups

class DisplayFilter {

# Constructor function DisplayFilter() { global $wgParser,$wgDisplayFilterMagic; $wgParser->setFunctionHook($wgDisplayFilterMagic,array($this,'filter')); }

# Expand the filter-magic function filter(&$parser) { $this->addJS(); $argv = array(); foreach (func_get_args() as $arg) if (!is_object($arg)) { $arg = ereg_replace('[\\\\\'"]',,$arg); if (preg_match('/^(.+?)\\s*=\\s*(.+)$/',$arg,$match)) $argv[$match[1]] = $match[2]; else $argv[] = $arg; } $anchor = array_shift($argv); $atts = array(); $atts['href'] = "javascript:filter(['".join("','",$argv)."'])"; $link = '<a'; foreach ($atts as $k => $v) $link .= " $k=\"$v\""; $link .= ">$anchor</a>"; return array($link,'noparse' => true, 'isHTML' => true); }

# Needed in some versions to prevent Special:Version from breaking function __toString() { return 'Display Filter'; }

  1. Called from $wgExtensionFunctions array when initialising extensions

function wfSetupDisplayFilter() { global $wgDisplayFilter; $wgDisplayFilter = new DisplayFilter(); $wgDisplayFilter->addJS(); # addScript doesn't seem to work from within parser }

  1. Needed in MediaWiki >1.8.0 for magic word hooks to work properly

function wfDisplayFilterLanguageGetMagic(&$magicWords,$langCode = 0) { global $wgDisplayFilterMagic; $magicWords[$wgDisplayFilterMagic] = array(0,$wgDisplayFilterMagic); return true; } ?> </php>
