The #when parser-function is used to add time information categories to articles. Just add a single parameter which can be arbitrarily formatted time information, for example:
- {{#when:2009/4/24}}
- {{#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 = ''; $formats = array('A','d','B','Y'); if (ereg(':|[ap]m',$when)) array_unshift($formats,'T'); foreach($formats as $f) $cats .= '[[Category:'.strftime("%$f",$time).']]'; return $cats; } function wfWhenLanguageGetMagic(&$magicWords,$langCode = 0) { $magicWords['when'] = array(0,'when'); return true; } ?>
