购物车中已移除商品的观察者 [英] Observer for removed items in the cart

问题描述

当产品从购物车中移除时，是否有可用于观察事件的观察器?我没有找到.

Is there an observer which can be used to observe events when a product is removed from the cart? I haven't found any.

我发现的是 checkout_cart_update_items_after 可以在通过更改产品数量删除产品时使用它，但在用户使用删除按钮时则不能使用.我目前看到的唯一替代方法是 checkout_cart_save_after，它在购物车发生变化时使用.当然，这需要自定义逻辑来检查删除了哪个产品.不完美.

What I have found is checkout_cart_update_items_after which can be used if a product is removed by altering the product count, but not when the user uses the remove button. The only alternative I see in the moment is checkout_cart_save_after which is used whenever the cart changes. Of course this needs custom logic which check which product was removed. Not perfect.

那么有没有更好的方法来注意移除事件?

So is there a better way to watch out for remove events?

推荐答案

您可以使用 sales_quote_remove_item 事件，在 Mage_Sales_Model_Quote::removeItem() 中调度.
删除的项目作为参数传递给观察者.

You can use the sales_quote_remove_item event, dispatched in Mage_Sales_Model_Quote::removeItem().
The removed item is passed to the observer as an argument.

Mage::dispatchEvent('sales_quote_remove_item', array('quote_item' => $item));

要在事件观察器中获取关联的产品模型，请使用 $observer->getQuoteItem()->getProduct().

To get the associated product model in an event observer, use $observer->getQuoteItem()->getProduct().
