Magento: использование OR в addAttributeToFilter
Magento позволяет применять фильтры для своих коллекций. Для этого используется метод addAttributeToFilter (из класса Mage_Eav_Model_Entity_Collection_Abstract).
Базовое использование этого метода следующее:

<span style='color:#7f0055; background:#ffffe8; '><?php</span><span style='color:#000000; background:#ffffe8; '></span> <span style='color:#000000; background:#ffffe8; '>addAttributeToFilter</span><span style='color:#000000; background:#ffffe8; '>(</span><span style='color:#000000; background:#ffffe8; '>имя_атрибута</span><span style='color:#000000; background:#ffffe8; '>,</span><span style='color:#000000; background:#ffffe8; '> значение</span><span style='color:#000000; background:#ffffe8; '>)</span><span style='color:#000000; background:#ffffe8; '></span> <span style='color:#7f0055; background:#ffffe8; '>?></span> |
Но иногда возникает необходимость отфильтровать Magento коллекцию по нескольким атрибутам, используя логическое “ИЛИ”.
Следующий пример показывает как получить коллекцию пользователей по заданному имени или email:
