[Помощь] Вывод в корзине артикула родительского товара

[vicsk]

На моем сайте есть доработка: Существуют родительские товары и в них созданы дочерние товары.
Суть запроса в том, чтобы вывести в корзине, у дочерних товаров артикул родительского товара. ID родительского товара известен и передан в корзину путем добавления строки:

"parent" => $cart_item["parent"],
