Question

我希望在退出用户后清除或删除购物车中的所有商品。我找到了这个，但我不知道我要把它放在哪里

foreach( Mage::getSingleton('checkout/session')->getQuote()->getItemsCollection() as $item ){
 Mage::getSingleton('checkout/cart')->removeItem( $item->getId() )->save();
}

Answer 1

您需要为“customer_logout”事件创建一个观察者。

Answer here describe how to create observer

您只需使用“customer_logout”而不是“catalog_product_save_before”。

以下代码对我来说很好：

在/app/etc/modules/Mycompany_Cleancart.xml

中

<?xml version="1.0"?>
<config>
  <modules>
    <Mycompany_Cleancart>
      <active>true</active>
      <codePool>local</codePool>
      <depends>
            <Mage_Catalog />
      </depends>
      <version>0.1.0</version>
    </Mycompany_Cleancart>
  </modules>
</config>

在/app/code/local/Mycompany/Cleancart/etc/config.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Mycompany_Cleancart>
            <version>0.1.0</version>
        </Mycompany_Cleancart>
    </modules>
    <global>
        <models>
            <mycompany_cleancart>
                <class>Mycompany_Cleancart_Model</class>
            </mycompany_cleancart>
        </models>
    </global>
    <frontend>
        <events>
            <customer_logout><!-- event observer -->
                <observers>
                    <Mycompany_Cleancart>
                        <class>mycompany_cleancart/observer</class>
                        <method>cleancart</method>
                    </Mycompany_Cleancart>
                </observers>
            </customer_logout>
        </events>
    </frontend>
</config>

在/app/code/local/Mycompany/Cleancart/Model/Observer.php

<?php

class Mycompany_Cleancart_Model_Observer {

    public function cleancart(Varien_Event_Observer $observer){
        foreach( Mage::getSingleton('checkout/session')->getQuote()->getItemsCollection() as $item ){
            Mage::getSingleton('checkout/cart')->removeItem( $item->getId() )->save();

        }
    }
}
