Override Adminhtml Core Controller not working (EE 1.14)

Question

I would like to override the core Controller.

Path: app\code\core\Mage\Adminhtml\controllers\Sales\OrderController.php

And then, I create the custom extension for overriding this controller.

Here is my file structure:

config: app\code\local\Mypackage\MyModule\etc\config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Mypackage_MyModule>
            <version>0.1.0</version>
        </Mypackage_MyModule>
    </modules>
    <admin>
        <routers>
            <adminhtml>
                <args>
                    <modules>
                        <Mypackage_MyModule before="Mage_Adminhtml">Mypackage_MyModule</Mypackage_MyModule>
                    </modules>
                </args>
            </adminhtml>
        </routers>
    </admin>
</config>

controllers: app\code\local\Mypackage\MyModule\controllers\Sales\OrderController.php

<?php
require_once Mage::getModuleDir('controllers', 'Mage_Adminhtml').DS.'Sales_OrderController.php';

class Mypackage_MyModule_Sales_OrderController extends Mage_Adminhtml_Sales_OrderController
{
    /**
     * View order detale
     */
    public function viewAction()
    {
        $this->_title($this->__('Sales'))->_title($this->__('Orders'));

        //etc...
    }
}

However, it don't work.

Any suggestion for me? Please help. Thank you.

EDIT:

I am using EE 1.14

EDIT2:

I had modified these file:

config.xml:

<?xml version="1.0"?>
<config>
    <modules>
        <Mypackage_MyModule>
            <version>0.1.0</version>
        </Mypackage_MyModule>
    </modules>
    <admin>
        <routers>
            <adminhtml>
                <args>
                    <modules>
                        <Mypackage_MyModule before="Mage_Adminhtml">Mypackage_MyModule_Adminhtml</Mypackage_MyModule>
                    </modules>
                </args>
            </adminhtml>
        </routers>
    </admin>
</config>

app\code\local\Mypackage\MyModule\controllers\Adminhtml\Sales\OrderController.php:

<?php
require_once(Mage::getModuleDir('controllers','Mage_Adminhtml').DS.'Sales' . DS . 'OrderController.php');

class Mypackage_MyModule_Adminhtml_Sales_OrderController extends Mage_Adminhtml_Sales_OrderController
{
    /**
     * View order detale
     */
    public function viewAction()
    {
        die(":D"); //for test
    }
}

But still don't work:(

Modules : app/etc/modules/Mypackage_MyModule.xml

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

EDIT3:

I had found the issue. The problem had written on below reply message.

Answer 1

You included OrderController.php wrongly. It should be like this :

require_once(Mage::getModuleDir('controllers','Mage_Adminhtml').DS.'Sales' . DS . 'OrderController.php');

Ensure your development mode is ON and cache is removed. This will definitely point out the error in your codes.

---

Also it is better to move your controllers in a directory called Adminhtml. So that you can uniquely distinguish both frontend controller and admin controllers. In order to do this, you need to do this.

File : config.xml

<config>
    <admin>
        <routers>
            <adminhtml>
                <args>
                    <modules>
                        <Mypackage_MyModule before="Mage_Adminhtml">Mypackage_MyModule_Adminhtml</Mypackage_MyModule>
                    </modules>
                </args>
            </adminhtml>
        </routers>
    </admin>
</config>

File : app\code\local\Mypackage\MyModule\controllers\Adminhtml\Sales\OrderController.php

<?php
require_once(Mage::getModuleDir('controllers','Mage_Adminhtml').DS.'Sales' . DS . 'OrderController.php');

class Mypackage_MyModule_Adminhtml_Sales_OrderController extends Mage_Adminhtml_Sales_OrderController
{
    /**
     * View order detale
     */
    public function viewAction()
    {
        $this->_title($this->__('Sales'))->_title($this->__('Orders'));

        //etc...
    }
}

Answer 2

I have already find out the answer.

As I am using EE 1.14, therefore, my Magento system have another Core programm called "Enterprise".

And, I find out Enterprise_SalesArchive this module had already overrided the app\code\core\Mage\Adminhtml\controllers\Sales\OrderController.php once.

app\code\core\Enterprise\SalesArchive\etc\config.xml:

<admin>
        <routers>
            <adminhtml>
                <args>
                    <modules>
                        <enterprise_salesarchive before="Mage_Adminhtml">Enterprise_SalesArchive_Adminhtml</enterprise_salesarchive>
                    </modules>
                </args>
            </adminhtml>
        </routers>
    </admin>

Therefore, Here is my answer.

config.xml:

<config>
    <modules>
        <Mypackage_MyModule>
            <version>0.1.0</version>
        </Mypackage_MyModule>
    </modules>
    <admin>
        <routers>
            <adminhtml>
                <args>
                    <modules>
                        <Mypackage_MyModule before="Enterprise_Salesarchive">Mypackage_MyModule_Adminhtml</Mypackage_MyModule>
                    </modules>
                </args>
            </adminhtml>
        </routers>
    </admin>
</config>

app\code\local\Mypackage\MyModule\controllers\Adminhtml\Sales\OrderController.php:

<?php
require_once 'Enterprise/SalesArchive/controllers/Adminhtml/Sales/OrderController.php';

class Mypackage_MyModule_Adminhtml_Sales_OrderController extends Enterprise_SalesArchive_Adminhtml_Sales_OrderController
{
    /**
     * View order detale
     */
    public function viewAction()
    {
        die(":DD"); //for test
    }
}

Thanks for you all help.

Admin configuration should be content Adminhtml in xml tag so your configuration in config.xml will be like below

 <!--Admin Configuration -->
    <admin>
        <routers>
            <adminhtml>
                <args>
                    <modules>
                        <Mypackage_MyModule before="Mage_Adminhtml">Mypackage_MyModule_Adminhtml</Mypackage_MyModule>
                    </modules>
                </args>
            </adminhtml>
        </routers>
    </admin>

And your controller file should be like

require_once(Mage::getModuleDir('controllers', 'Mage_Adminhtml').DS."Sales".DS."OrderController.php");

class Mypackage_MyModule_Adminhtml_Sales_OrderController extends  Mage_Adminhtml_Sales_OrderController {

 /**
     * View order detail
     */
    public function viewAction()
    {
        $this->_title($this->__('Sales'))->_title($this->__('Orders'));

        //etc...
    }

}

hope it will work from your end.

Answer 4

You need to change

require_once Mage::getModuleDir('controllers', 'Mage_Adminhtml').DS.'Sales_OrderController.php';

to

require_once Mage::getModuleDir('controllers', 'Mage_Adminhtml').DS.'Sales'.DS.'OrderController.php';

Your code Mage::getModuleDir('controllers', 'Mage_Adminhtml').DS.'Sales_OrderController.php'; generate output like

Mage/Adminhtml/controllers/Sales_OrderController.php

and which is wrong.

Also you need to change rewrite code at config.xml

Answer 5

in config.xml

<Mypackage_MyModule before="Mage_Adminhtml">Mypackage_MyModule_Adminhtml</Mypackage_MyModule>

controller path must be.

controllers: app\code\local\Mypackage\MyModule\controllers\Adminhtml\Sales\OrderController.php

because it will look for so the controller file will be

<?php
require_once Mage::getModuleDir('controllers', 'Mage_Adminhtml').DS.'Sales'.DS.'OrderController.php';


class Mypackage_MyModule_Adminhtml_Sales_OrderController extends Mage_Adminhtml_Sales_OrderController
{
    /**
     * View order detale
     */
    public function viewAction()
    {
        $this->_title($this->__('Sales'))->_title($this->__('Orders'));

        //etc...
    }
}
