Question

我必须尝试在magento中覆盖购物车控制器。但它似乎没有在magento 1.8中覆盖。我做了以下事情

添加了

等文件

Magento/app/code/local/MyNameSpace/MyCheckout/etc/config.xml
Magento/app/code/local/MyNameSpace/MyCheckout/controllers/CartController.php
Magento/app/etc/modules/MyNameSpace_MyCheckout.xml

，内容为

config.xml中

MyNameSpace_MyCheckout.xml

<?xml version="1.0"?>
<config>
    <modules>
    <MyNameSpace_Mycheckout>
            <active>true</active>
            <codePool>local</codePool>
    </MyNameSpace_Mycheckout>
    </modules>
</config>

我发现"cartController.php"中没有文件Mage/Checkout/controllers/。在magento 1.8中，我只能在该目录中找到一个名为Action.php的文件，该文件只有一个抽象类。任何人都可以解释如何在magento 1.8中覆盖购物车控制器吗？

在config.xml文件中试用此代码

修改

<frontend>
    <routers>
        <mycheckout>
            <use>standard</use>
            <args>
               <module>MyNameSpace_Mycheckout</module>
               <frontName>mycheckout</frontName>
            </args>
        </mycheckout>
    </routers>
</frontend>
<global>
    <rewrite>
        <mycheckout> <!--unique tag-->
            <from><![CDATA[#^/checkout/cart/add#]]></from>
            <to>/mycheckout/cart/add</to>
        </mycheckout>
    </rewrite>
</global>

替换为此代码。

<frontend>
    <routers>
        <MyNameSpace_Mycheckout>
            <use>standard</use>
            <args>
                <module>MyNameSpace_Mycheckout</module>
                <frontName>mycheckout</frontName>
            </args>
        </MyNameSpace_Mycheckout>
    </routers>
</frontend>
<global>
    <routers>
        <checkout>
            <rewrite>
                <cart>
                    <to>mycheckout/cart</to>
                    <override_actions>true</override_actions>
                    <actions>
                        <add>
                            <to>mycheckout/cart/add</to>
                        </add>
                    </actions>
                </cart>
            </rewrite>
        </checkout>
    </routers>
</global>

购物车控制器覆盖在magento 1.8中不起作用
