php - WooCommerce Cart REST Api 无法将购物车与特定用户相关联
问题描述
我正在使用 PHP laravel 开发 WooCommerce Cart REST Api。以下是此类 api 的代码片段。当我调用add_to_cart函数时,它确实将产品添加到购物车中,我可以看到wp_woocommerce_sessions表中存储了一条具有任意会话键值的记录。但我不知道如何将该记录与特定用户相关联,因此每个用户都有自己的购物车记录,当我使用特定用户 ID调用get_cart函数或其他两个函数(即remove_item或clear_cart )时,它会获取相关记录只给那个用户而不是任意记录。现在发生了什么,例如,如果我调用add_to_cart具有给定用户 id 的函数,例如 id 为 2,则存储一条记录,然后如果我用另一个用户 id 调用get_cart函数,例如 id 为 1,我仍然得到以前存储的记录用户 2. 我希望我能很好地解释我的问题......
我尝试在代码的顶部添加私有函数set_current_user,因为我认为它可能有助于解决问题,但是,它所做的只是将wp_woocommerce_sessions的会话密钥值更改为与用户 ID 不是任意值。另外,我尝试检查 woocommerce rest api 文档。和 wc_cart 类文档。最后尝试谷歌寻求解决方案。

我希望根据用户 ID 有一个特定于给定用户的购物车,并且当我添加/检索/删除/清除购物车时,这些操作适用于该特定用户的购物车,但是,实际结果不是这样的
解决方案
我发现我应该使用当前用户 id 从用户元表中读取元数据购物车条目并将其加载到当前会话中,在内存购物车对象中完成后,我应该更新用户元条目。 .
