Изменить способ сортировки товаров в категории (исходя из сортировки Производителей в админке)


 Share

Recommended Posts

Добрый день! Никогда с подобным не сталкивался, но есть такая вот задача: в Производителях установлен порядок сортировки, можно ли исходя из этого порядка сортировки выводить товары в категориях?

Спасибо заранее за ответ :)

Можно, подключить в getProducts таблицу manufacturer и немножко поменять p.sort_order на m.sort_order

 

 

 

получится примерно так

 

Скрытый текст
	public function getProducts($data = array()) {
		$sql = "SELECT p.product_id, (SELECT AVG(rating) AS total FROM " . DB_PREFIX . "review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating, (SELECT price FROM " . DB_PREFIX . "product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '" . (int)$this->config->get('config_customer_group_id') . "' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, (SELECT price FROM " . DB_PREFIX . "product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '" . (int)$this->config->get('config_customer_group_id') . "' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special";

Если товаров много, подключением дополнительной таблицы можно существенно замедлить запрос выборки товара. Мне кажется тут нужно уже сохранять порядок сортировки товара в админке, добавляя к нему в качестве префикса порядок сортировки производителя
