Magento覆盖控制器 [英] Magento override controller
问题描述
我想做上述。
Ive overridden many files in the past ... block，model，helper .... but this one eludes me。
任何人都可以看到错误在这里：
（ive编辑此代码...以包括一些推荐现在...）
剩下我的文件夹结构a test）：
/Idigital/Idgeneral/etc/config.xml
/ Idigital / Idgeneral / controllers / Checkout /CartController.php
/Idigital/Idgeneral/controllers/CartController.php
.xml：
<？xml version =1.0？>
< config>
< modules>
< idigital_idgeneral>
< version> 0.1.0< / version>
< / idigital_idgeneral>
< / modules>
< global>
< blocks>
< idgeneral>< class> Idigital_Idgeneral_Block< / class>< / idgeneral>
< / blocks>
< / global>
< frontend>
< routers>
< checkout>
< use> standard< / use>
< args>
< modules>
< Idigital_Idgeneral before =Mage_Checkout> Idigital_Idgeneral_Checkout< / Idigital_Idgeneral>
< / modules>
< / args>
< / checkout>
< / routers>
< layout>
< updates>
< idgeneral>
< file> idigital.xml< / file>
< / idgeneral>
< / updates>
< / layout>
< / frontend>
< / config>
我把控制器文件放在2个位置进行测试。
和我的FIRST控制器文件的顶部
require_once'Mage / Checkout / controllers / CartController.php' ;
class Idigital_Idgeneral_Checkout_CartController extends Mage_Checkout_CartController
{
public function testAction（）
{
var_dump（'inside checkout / cart / test' ;出口;
}
/ **
*将产品添加到购物车action
* /
public function addAction（）
{
blah ...
}
回答我的第二个控制器：
require_once'Mage / Checkout / controllers / CartController.php';
class Idigital_Idgeneral_CartController extends Mage_Checkout_CartController
{
public function testAction（）
{
var_dump（'inside cart / test'）; exit ;
}
/ **
*将产品添加到购物车action
* /
public function addAction（）
{
blah ...
}
当我访问：/ checkout / cart / add
Im指向法师控制器...不是我的本地。
当我访问/ checkout / cart /测试 - 我得到一个404 $ b $（我有var_dump stmts在每个...我可以看到哪个是） b当我访问/购物车/添加或购物车/测试 - 我得到一个404
当我访问idgeneral / cart /测试或idgeneral /购物车/添加 - 我得到一个404
code> app / code / local / MyNameSpace / MyModule / etc / config.xml
app / code / local / MyNameSpace / MyModule / controllers / Checkout / CartController.php
app / etc / modules /MyNameSpace_All.xml
编辑/etc/config.xml并建立应用程式/ /MyNameSpace/MyModule/etc/config.xml包含以下内容：
<？xml version =1.0？ ;
< config>
< modules>
< MyNameSpace_MyModule>
< version> 0.1.0< / version>
< / MyNameSpace_MyModule>
< / modules>
< global>
<！ - 可以将此重写规则添加到数据库 - >
< rewrite>
<！ - 这是您的重写的标识符，应该是唯一的 - >
<！ - 这是您自己的控制器中的类别名称>
< mynamespace_mymodule_checkout_cart>
< from><！[CDATA [＃^ / checkout / cart /＃]]>< / from>
<！ -
- mymodule匹配路由器名称下面
- checkout_cart匹配控制器的路径
考虑到下面的路由器，/ mymodule / checkout_cart /将
translated更改为/MyNameSpace/MyModule/controllers/Checkout/CartController.php（？）
- >
< to> / mymodule / checkout_cart /< / to>
< / mynamespace_mymodule_checkout_cart>
< / rewrite>
< / global>
<！ -
如果你想重载一个管理控制器，这个标签应该是< admin>而是
或< adminhtml>如果你超载这样的东西（？）
- >
< frontend>
< routers>
< use> standard< / use>
< args>
< module> MyNameSpace_MyModule< / module>
<！ - 当捕获上面的重写 - >
< frontName> mymodule< / frontName>
< / args>
< / mynamespace_mymodule>
< / routers>
< / frontend>
注意：当我覆盖目录/产品控制器时，为我工作。我必须使用：
< from><！[CDATA [＃^ catalog / product /＃]]& < / from>
< to> mymodule / mycontroller< / to>
（注意缺少的前导斜杠）
自从Magento 1.3，你可以简单地添加你的模块到前端路由器。重写不再是必要的：
<？xml version =1.0encoding =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），并返回Magento的
如果控制器位于另一个文件夹中，则必须修改代码：
app / code / local / MyNameSpace / MyModule / controllers / Checkout / CartController.php。
替换
< MyNameSpace_MyModule before = Mage_Checkout> MyNameSpace_MyModule< / MyNameSpace_MyModule>
with
< MyNameSpace_MyModule before =Mage_Checkout> MyNameSpace_MyModule_Checkout< / MyNameSpace_MyModule>
编辑
/CartController.php'
创建
app / code / local / MyNameSpace / MyModule / controllers / Checkout / CartController。具有以下内容的php（对indexAction（）的唯一更改是添加一个error_log（）调用）：<？php
＃控制器不是自动加载的，所以我们必须手动执行：
require_once'Mage / Checkout / controllers / CartController.php';
类MyNameSpace_MyModule_Checkout_CartController extends
Mage_Checkout_CartController
{
＃重载的indexAction
public function indexAction（）{
＃只是为了确保
error_log我做到了！'）;
parent :: indexAction（）;
}
}
'app / etc / modules / MyNameSpace_All.xml'
（这是为了激活您的模块）
true
local
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：< mynamespace_mymodule_checkout_cart_index>
< update handle =checkout_cart_index/>
< / mynamespace_mymodule_checkout_cart_index>
（请注意，这些标签看起来是区分大小写的。对于你）
[通过Hendy：当我使用本Wiki或这里描述的方法覆盖目录/产品/视图时，我没有做上述。但是，当使用'cms方式'，我不得不手动更新手柄。]
上面的项目没有为我工作M Carvalho）
我发现要更改的文件是app / design / frontend / [myinterface] / [mytheme] /layout/mymodule.xml
添加以下行：
- 将您的浏览器指向/ checkout / cart /
在您的PHP错误日志中，您会发现是的，我做到了！。
您需要使用重写正则表达式更加精确，因为错误很难找到。
I would like to do the above. Ive overridden many files in the past...block, model, helper....but this one eludes me.
Can anyone see what im doing wrong here: (ive edited this code...to include some of the recomendations now...)
Heres my folder structure (2 controller locations as a test):
/Idigital/Idgeneral/etc/config.xml /Idigital/Idgeneral/controllers/Checkout/CartController.php /Idigital/Idgeneral/controllers/CartController.phpHeres my config.xml:
<?xml version="1.0"?> <config> <modules> <idigital_idgeneral> <version>0.1.0</version> </idigital_idgeneral> </modules> <global> <blocks> <idgeneral><class>Idigital_Idgeneral_Block</class></idgeneral> </blocks> </global> <frontend> <routers> <checkout> <use>standard</use> <args> <modules> <Idigital_Idgeneral before="Mage_Checkout">Idigital_Idgeneral_Checkout</Idigital_Idgeneral> </modules> </args> </checkout> </routers> <layout> <updates> <idgeneral> <file>idigital.xml</file> </idgeneral> </updates> </layout> </frontend> </config>Ihave placed my controller file in 2 locations to test. And heres the top of my FIRST controller file:
require_once 'Mage/Checkout/controllers/CartController.php'; class Idigital_Idgeneral_Checkout_CartController extends Mage_Checkout_CartController { public function testAction() { var_dump('inside checkout/cart/test');exit; } /** * Add product to shopping cart action */ public function addAction() { blah... }Ans my second controller:
require_once 'Mage/Checkout/controllers/CartController.php'; class Idigital_Idgeneral_CartController extends Mage_Checkout_CartController { public function testAction() { var_dump('inside cart/test');exit; } /** * Add product to shopping cart action */ public function addAction() { blah... }When i visit: /checkout/cart/add Im directed to the mage controller...not my local. (i have var_dump stmts in each..so i can see which is ran).
When i visit /checkout/cart/test - i get a 404 When i visit /cart/add or cart/test - i get a 404 when i visit idgeneral/cart/test or idgeneral/cart/add - i get a 404
解决方案
Create your module folders and files
app/code/local/MyNameSpace/MyModule/etc/config.xml app/code/local/MyNameSpace/MyModule/controllers/Checkout/CartController.php app/etc/modules/MyNameSpace_All.xmlEdit /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>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>(notice the missing leading slash)
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>Please note that
before="Mage_Checkout"will load your controller first if available and fall back to Magento’s if not.If the controller is in another folder, you’ll have to modify the code:
app/code/local/MyNameSpace/MyModule/controllers/Checkout/CartController.php.Replace
<MyNameSpace_MyModule before="Mage_Checkout">MyNameSpace_MyModule</MyNameSpace_MyModule>with
<MyNameSpace_MyModule before="Mage_Checkout">MyNameSpace_MyModule_Checkout</MyNameSpace_MyModule>
Edit
'controllers/Checkout/CartController.php'Create
app/code/local/MyNameSpace/MyModule/controllers/Checkout/CartController.phpwith 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(); } }
Edit
'app/etc/modules/MyNameSpace_All.xml'(This is to activate your module)true local
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>(Note that these tags seem to be case sensitive. Try using all lowercase if this isn’t working for you)
[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.]
The above item did not work for me (2009-02-19 by Jonathan M Carvalho)
I discovered that the file to change is app/design/frontend/[myinterface]/[mytheme]/layout/mymodule.xml
Add the following lines:
- Point your browser to /checkout/cart/ In your PHP error log, you should find ‘Yes, I did it!’.
You need to be extra precise with the rewrite regular expression because errors are very hard to find.
