Hm, zajrzyj do klasy Address.php w folderze /classes/
tam masz:
protected $fieldsRequired = array('id_country', 'alias', 'lastname', 'firstname', 'address1', 'postcode', 'city');
protected $fieldsSize = array('alias' => 32, 'company' => 32, 'lastname' => 32, 'firstname' => 32,
'address1' => 128, 'address2' => 128, 'postcode' => 12, 'city' => 64,
'other' => 300, 'phone' => 16, 'phone_mobile' => 16);
protected $fieldsValidate = array('id_customer' => 'isNullOrUnsignedId', 'id_manufacturer' => 'isNullOrUnsignedId',
'id_supplier' => 'isNullOrUnsignedId', 'id_country' => 'isUnsignedId', 'id_state' => 'isNullOrUnsignedId',
'alias' => 'isGenericName', 'company' => 'isGenericName', 'lastname' => 'isName',
'firstname' => 'isName', 'address1' => 'isAddress', 'address2' => 'isAddress',
'postcode' => 'isPostCode', 'city' => 'isCityName', 'other' => 'isMessage',
'phone' => 'isPhoneNumber', 'phone_mobile' => 'isPhoneNumber', 'deleted' => 'isBool');
Te tablice przechowują które pola są wymagane, jak validowane etc.
