编辑/etc/config.xml 并使用以下内容创建 app/code/local/MyNameSpace/MyModule/etc/config.xml:

Edit /etc/config.xml and Create app/code/local/MyNameSpace/MyModule/etc/config.xml with the following content:

<?xml version="1.0"?>
 <config>
<modules>
    <MyNameSpace_MyModule>
        <version>0.1.0</version>
    </MyNameSpace_MyModule>
</modules>
<global>
    <!-- This rewrite rule could be added to the database instead -->
    <rewrite>
        <!-- This is an identifier for your rewrite that should be unique -->
        <!-- THIS IS THE CLASSNAME IN YOUR OWN CONTROLLER -->
        <mynamespace_mymodule_checkout_cart>
            <from><![CDATA[#^/checkout/cart/#]]></from>
            <!--
                - mymodule matches the router frontname below
                - checkout_cart matches the path to your controller

                Considering the router below, "/mymodule/checkout_cart/" will be
                "translated" to "/MyNameSpace/MyModule/controllers/Checkout/CartController.php" (?)
            -->
            <to>/mymodule/checkout_cart/</to>
        </mynamespace_mymodule_checkout_cart>
    </rewrite>
</global>
<!--
If you want to overload an admin controller this tag should be <admin> instead,
or <adminhtml> if youre overloading such stuff (?)
-->
<frontend>
    <routers>
        <mynamespace_mymodule>
            <!-- should be set to "admin" when overloading admin stuff (?) -->
            <use>standard</use>
            <args>
                <module>MyNameSpace_MyModule</module>
                <!-- This is used when "catching" the rewrite above -->
                <frontName>mymodule</frontName>
            </args>
        </mynamespace_mymodule>
    </routers>
</frontend>

注意:当我覆盖目录/产品控制器时，以上对我不起作用.我不得不使用:

Note: The above didn’t work for me when I override catalog/product controller. I had to use:

            <from><![CDATA[#^catalog/product/#]]></from>
            <to>mymodule/mycontroller</to>

(注意缺少的前导斜线)

(notice the missing leading slash)

自 Magento 1.3 起，您只需将模块添加到前端路由器即可.不再需要重写:

Since Magento 1.3 you can simply add your module to the frontend router. Rewrites are not neccessary any more:

  <?xml version="1.0" encoding="UTF-8"?>
 <config>
<modules>
    <MyNameSpace_MyModule>
        <version>0.1.0</version>
    </MyNameSpace_MyModule>
</modules>

<frontend>
    <routers>
        <checkout>
            <args>
                <modules>
                    <MyNameSpace_MyModule before="Mage_Checkout">MyNameSpace_MyModule</MyNameSpace_MyModule>
                </modules>
            </args>
        </checkout>
    </routers>
</frontend>

请注意，before="Mage_Checkout" 将首先加载您的控制器(如果可用)，如果没有，则回退到 Magento.

Please note that before="Mage_Checkout" will load your controller first if available and fall back to Magento’s if not.

如果控制器在另一个文件夹中，则必须修改代码:
app/code/local/MyNameSpace/MyModule/controllers/Checkout/CartController.php.

If the controller is in another folder, you’ll have to modify the code:
app/code/local/MyNameSpace/MyModule/controllers/Checkout/CartController.php.

替换

<MyNameSpace_MyModule before="Mage_Checkout">MyNameSpace_MyModule</MyNameSpace_MyModule>

与

    <MyNameSpace_MyModule before="Mage_Checkout">MyNameSpace_MyModule_Checkout</MyNameSpace_MyModule>

1. 编辑'controllers/Checkout/CartController.php'

使用以下内容创建 app/code/local/MyNameSpace/MyModule/controllers/Checkout/CartController.php:(对 indexAction() 的唯一更改是添加一个 error_log() 调用):

Create app/code/local/MyNameSpace/MyModule/controllers/Checkout/CartController.php with the following content: (the only change to indexAction() is adding an error_log() call):

    <?php
       # Controllers are not autoloaded so we will have to do it manually:
       require_once 'Mage/Checkout/controllers/CartController.php';
       class MyNameSpace_MyModule_Checkout_CartController extends
                       Mage_Checkout_CartController
    {
    # Overloaded indexAction
     public function indexAction() {
    # Just to make sure
    error_log('Yes, I did it!');
    parent::indexAction();
    }
     }

1. 编辑'app/etc/modules/MyNameSpace_All.xml'(这是为了激活你的模块)

1. Edit 'app/etc/modules/MyNameSpace_All.xml' (This is to activate your module)

真的当地的

编辑 'app/design/frontend/[myinterface]/[mytheme]/layout/checkout.xml' 并添加以下内容以使用与之前相同的更新句柄:>

Edit 'app/design/frontend/[myinterface]/[mytheme]/layout/checkout.xml' and add the following to use the same update handle as before:

 <mynamespace_mymodule_checkout_cart_index>
    <update handle="checkout_cart_index"/>
  </mynamespace_mymodule_checkout_cart_index>

(请注意，这些标签似乎区分大小写.如果这不适合您，请尝试全部使用小写)

(Note that these tags seem to be case sensitive. Try using all lowercase if this isn’t working for you)

[by Hendy:当我使用本 Wiki 或此处描述的方法覆盖目录/产品/视图时，我不必执行上述操作.然而，当使用'cms方式'时，我不得不手动更新句柄.]

[by Hendy: When I override catalog/product/view using the method described in this Wiki or here, I didn’t have to do the above. However, when using the 'cms way', I had to update the handle manually.]

以上项目对我不起作用(2009-02-19 by Jonathan M Carvalho)

The above item did not work for me (2009-02-19 by Jonathan M Carvalho)

我发现要更改的文件是 app/design/frontend/[myinterface]/[mytheme]/layout/mymodule.xml

I discovered that the file to change is app/design/frontend/[myinterface]/[mytheme]/layout/mymodule.xml

添加以下几行:

1. 将浏览器指向/checkout/cart/在您的 PHP 错误日志中，您应该看到是的，我做到了！".

您需要特别精确地重写正则表达式，因为错误很难发现.

You need to be extra precise with the rewrite regular expression because errors are very hard to find.
