Question

我有一个闪存模块，用于计算产品的测量值，一旦计算出来，就可以将按钮添加到购物车中看到此错误：

[PrestaShopDatabaseException]

为'PRIMARY'重复输入'739-6261-21011-0'

UPDATE `ps_cart_product`
        SET `id_address_delivery` = (
            SELECT `id_address_delivery` FROM `ps_cart`
            WHERE `id_cart` = 739 AND `id_shop` = 1
        )
        WHERE `id_cart` = 739

如果支付分为5个步骤prestashop，如果它有效，但One Page Checkout模块不起作用，则会出现此错误。

Answer 1

我看到你在Prestashop官方论坛上接受了回复，我将在此发布

key n ps_cart_product表包含4个元素：    - id_cart    - id_product    - id_address_delivery    - id_product_attribute
     在您的查询中
更新关键元素（id_address_delivery）   从你的SQL更新我看到id_address_delivery等于：21011   这个id购物车和产品的条目已经存在！

但是你可以解释一下这对你有什么帮助吗？
