Magento ermöglicht es, benutzerdefinierte Aufgaben (cronjobs) mittels der config.xml in den einzelnen Modulen zu planen. Das geschieht in ähnlicher Weise wie in der UNIX-Welt.

Um diese cronjobs besser verwalten zu können, ist es dabei recht Sinnvoll diese an einer zentralen Stelle vorzufinden. Wir haben dazu z.B. alle cronjobs unter /app/code/community/DigitalVertraut/base/config.xml zusammengefasst.

Alle im System vorhanden cronjobs erhalten sie mit den folgenden paar Zeilen. So können Sie auch leicht testen, ob Ihre Änderungen erfolgreich vom System übernommen wurden.

include 'app/Mage.php';

Mage::app();

$crontab = Mage::getConfig()->getNode('crontab/jobs');

print_r($crontab);
