Using a cron to set catalog price rules

Sometimes you might want to update your catalog price rules at different times of the day, to make sure they’re applied. So, lets look at a script we can schedule and run through a cron task.

require_once '../Mage.php';
Mage::setIsDeveloperMode(true);
umask(0);
Mage::app('default');
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

try {
    Mage::getModel('catalogrule/rule')->applyAll();
    Mage::app()->removeCache('catalog_rules_dirty');
    echo Mage::helper('catalogrule')->__('The rules have been applied.');
} catch (Exception $exception) {
    echo Mage::helper('catalogrule')->__('Unable to apply rules.');
    echo $exception->getMessage();
}
