Подскажите ребята, нужно добавить товар с разным артикулом по цвету и по размеру как отдельную позицию, и сгруппировать их по коду:
Например: есть товар с кодом V-0257, и у него 3 цвета и 2 размера и артикул с кодом по цвету и по размеру выглядит следующим образом V-0257-01-02.
Есть отдельное поле в таблице для кода товара V-0257. То есть мне нужно каждый цвет и размер добавлять как отдельную позицию, пример:
V-0257-01-01
V-0257-02-01
V-0257-03-01
V-0257-01-02
V-0257-02-02
V-0257-03-02
Скажите пожалуйста как мне изменить следующий код opencart 2.2
public function getProducts ($data = array()) {
$sql =
