Question

如何重写一个Magento控制器方法

Answer 1

1.创建模块文件

app/code/local/Wangdz/Checkout/etc/config.xml

app/code/local/Wangdz/Checkout/controllers/CartController.php

app/etc/modules/Wangdz_All.xml

2. 编辑 /etc/config.xml文件

创建 app/code/local/Wangdz/Checkout/etc/config.xml文件并添加以下内容：

<?xml version="1.0"?>
<config>
<modules>
<Wangdz_Checkout>
<version>0.1.0</version>
</Wangdz_Checkout>
</modules>
<frontend>
<routers>
<wangdz_checkout>
<use>standard</use>
<args>
<module>Wangdz_Checkout</module>
<frontName>wangdz_checkout</frontName>
</args>
</wangdz_checkout>
</routers>
</frontend>
<global>
<blocks>
<wangdz_checkout>
<class>Wangdz_Checkout_Block</class>
</wangdz_checkout>
</blocks>
<rewrite>
<wangdz_checkout_cart>
<from><![CDATA[#^/checkout/cart/#]]></from>
<to>wangdz_checkout/cart/</to>
</wangdz_checkout_cart>
</rewrite>
</global>
</config>

3. 编辑 ”controllers/CartController.php”文件

app/code/local/Wangdz/Checkout/controllers/CartController.php 添加以下内容:

<?php
require_once 'Mage/Checkout/controllers/CartController.php';
class Wangdz_Checkout_CartController extends Mage_Checkout_CartController {
public function indexAction() {
echo "hello world!";
}
}
?>

4. 编辑”app/etc/modules/Wangdz_All.xml”文件

<Wangdz_Checkout>
<active>true</active>
<codePool>local</codePool>
</Wangdz_Checkout>

5. 将浏览器指向 /checkout/cart/

你会看到页面打印出:”hello world!”
