Question

我有一个magento商店，所有这些认为运作良好，第一次添加到购物车运作良好，成功结帐和付款完成。我想在我的购物车中添加另一个产品时，我无法在购物车中添加任何产品，退出后再次登录其运行良好，但付款完成后我无法在购物车中添加产品。我搜索了很多但是无法获得成功。请帮我简短一下这个问题。我使用的是magento 1.8.0.0

Answer 1

我遇到了同样的问题：

付款后，将产品插入购物车导致上述SQL错误
在空车中插入产品导致“空车”，即使添加其他产品会导致购物车同时设置两个项目。

我把它缩小到sales_quote_item_set_product上的观察者。在这个观察者中，我修改了QuoteItem（设置价格和添加选项），然后我保存了它。我认为储蓄导致了这个问题。

我将逻辑移到sales_quote_save_after事件，两个错误都消失了。希望它有所帮助。

Answer 2

使用sales_quote_add_item事件观察器时遇到此问题。我试图以编程方式编辑产品价格，同时将产品添加到购物车中。

我在 Observer 类中保存了引用项。

$quoteItem->save();

后来，我发现我们不需要保存引用项目对象，因为它会在以后通过引用传递时自动保存。

因此，解决方案是删除/评论该行：

// $quoteItem->save();

首次付款后，我无法在购物车中添加产品
