Question

1C-Bitrix

I'm trying to return the quantity of an item after adding it to the cart using ajax. I do so

CSaleBasket::GetList(false, ["FUSER_ID" => CSaleBasket::GetBasketUserID(), "LID" => SITE_ID, "ORDER_ID" => "NULL"], [], false, ['ID']);

Returned 3. It should be noted that the type of goods - kits.
