Template:When

This template is not actually used, the #when parser-function is used to add time information to articles. Just add a single parameter which can be arbitrarily formatted time information, for example:

{{#when:2009/4/24}} - best to do dates backwards like this otherwise it tries to use some weird American format

{{#when:24 apr 2009}}

{{#when:24 apr, 4:30pm}} - current year is used here since not specified

The function expands to a set of category links to categorise the article into year, month, day-of-month, full-weekday-name and time (24 hour HH:MM:SS format). Articles exhibiting time can then be matched with a DPL query, for example:

{{#dpl:category=2006|category=April}}

The parser function which adds this is very simple consisting of the following code in the LocalSettings.php file. <php> $wgExtensionFunctions[] = 'wfSetupWhen'; $wgHooks['LanguageGetMagic'][] = 'wfWhenLanguageGetMagic';

function wfSetupWhen() {

       global $wgParser;
       $wgParser->setFunctionHook('when','wfExpandWhen');
       return true;
       }

function wfExpandWhen(&$parser,$when) {

       $time = strtotime($when);
       $cats = ;
       foreach(array('T','A','d','B','Y') as $f) $cats .= ;
       return $cats;
       }

function wfWhenLanguageGetMagic(&$magicWords,$langCode = 0) {

       $magicWords['when'] = array(0,'when');
       return true;
       }

</php>
