Override magento controller

Every Magento project requires a certain level of customization. This may involve adding a new element or overriding an existing one. Today, we’ll talk about how to override a magento controller. For any suggestions & question, please feel free to drop a comment.

First Step:

I am overriding the customer controller. First thing will create new module file.
The file location will me  will be

app/etc/modules/QaisarSatti_Customer.xml

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

Second Step:

We will create module configuration file. So file location will be

app/code/local/QaisarSatti/Customer/etc/config.xml

<?xml version="1.0"?>
    <config>
        <modules>
            <QaisarSatti_Customer>
                <version>0.0.1</version>
            </QaisarSatti_Customer>
        </modules>
        <frontend>
            <routers>
                <customer>
                    <args>
                        <modules>
                            <QaisarSatti_Customer before="Mage_Customer">QaisarSatti_Customer</QaisarSatti_Customer>
                        </modules>
                    </args>
                </customer>
            </routers>
        </frontend>
    </config>

Third Step:

Now we will create the Our controller file.

app/code/local/QaisarSatti/Customer/controllers/AccountController.php

<?php

/**
* Overriding Customer account controller
*/

require_once Mage::getModuleDir('controllers', 'Mage_Customer') . DS . 'AccountController.php';

class QaisarSatti_Customer_AccountController extends Mage_Customer_AccountController {

public function ajaxAction() {  //if you want to create a custom method in customer controller
   echo 'Ajax cction is working!!';
}

public function loginAction() {
   echo 'Overring the Login Action is working';
}

}

Magento 2 load product by id

There are three way to get product load in magento 2. First Object Manager second factory Method and third on is Api Repository.

Factory Method:

Best practice method always use this method.

namespace QaisarSatti\Module\Block;

class Product extends \Magento\Framework\View\Element\Template
{

  protected $_product;  


  public function __construct(
     
        \Magento\Catalog\Model\ProductFactory $_product

    ) {


        $this->_productloader = $_productloader;
     
    }
    public function getLoadProduct()
    {
        $product_id=7;
        return $this->_productloader->create()->load($id);
    }

}

Api Repository:

This was introduce in Magento 2.1 by magento.

    namespace QaisarSatti\Module\Block;
    use Magento\Catalog\Api\ProductRepositoryInterface;
    class Product extends \Magento\Framework\View\Element\Template
     {
          protected $_productRepository;
       

          public function __construct(
         
            ProductRepositoryInterface $productRepository
          ) {
         

              $this->_productRepository = $productRepository;
          }
          public function getProduct()
          {
              $productId=7;
              return $product = $this->productRepository->getById($productId);
          }
      }

Object Manager:

No recommended method to use in magento2 but so magento use it so here it is just for knowledge.

$product_id=7;
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->create('Magento\Catalog\Model\Product')->load($product_id);

Magento 2 create a module or extension

In start of learning Magento 2 every developer must need to learn how to create a simple module or extension. But before start it you must have initial knowledge of Php too. Here it is easy way to create the extension or module in magento 2. In this custom module we have to learn how to create router,controller,block,xml layout and phtml files. Combination of these file will make a simple Hello World module. That will listed in admin module list and show the output on fronteend So lets start the fun learning of magento 2. Before we start playing with magento 2 we must do these tasks disabled cache from admin panel or you can do it via command (php bin/magento cache:disable) and set the developer mode on by following command (php bin/magento deploy:mode:set developer).
Note: Check code folder in your app directory. If not have code folder then create it.

First Step:

First step is register your module with registration.php . The file location will be

app/code/QaisarSatti/HelloWorld/registration.php

<?php
/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email [email protected]
*
*/

\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'QaisarSatti_HelloWorld',
__DIR__
);

Second Step:

Create module.xml file. In this file you will define your module name and version. The file location will be

app/code/QaisarSatti/HelloWorld/etc/module.xml

<?xml version="1.0"?>
<!--/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email [email protected]
*
*/ -->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="QaisarSatti_HelloWorld" schema_version="0.0.1" setup_version="0.0.1"/>
</config>

Third Step:

Create the block file.The file location will be

app/code/QaisarSatti/HelloWorld/Block/HelloWorld.php

<?php
/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email [email protected]
*
*/

namespace QaisarSatti\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
public function _prepareLayout()
{
parent::_prepareLayout();
$this->pageConfig->getTitle()->set(__('First Hello World Module'));
return $this;
}
}

Fourth Step:

Create the controller file.The file location will be

app/code/QaisarSatti/HelloWorld/Controller/Index/Index.php

<?php
/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email [email protected]
*
*/

namespace QaisarSatti\HelloWorld\Controller\Index;
class Index extends \Magento\Framework\App\Action\Action
{
public function execute()
{
$this->_view->loadLayout();
$this->_view->renderLayout();
}
}

Fifth Step:

Create frontend router. Here you will declare your frontName make sure it is unique name.

app/code/QaisarSatti/HelloWorld/etc/frontend/routes.xml

<?xml version="1.0"?>
<!--/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email [email protected]
*
*/ -->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="standard">
<route id="helloworld" frontName="helloworld">
<module name="QaisarSatti_HelloWorld" />
</route>
</router>
</config>

Sixth Step:

Create frontend template file.

app/code/QaisarSatti/HelloWorld/view/frontend/templates/HelloWorld.phtml

<?php
/**
* Catalog Product Rewrite Helper
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email [email protected]
*
*/

echo 'Hello World';
?>

Seventh Step:

Add frontend layout handle for your router. First letter will be your frontName as you mention in your router.xml file (helloworld) then your folder name (index) then in the last your controller name (Index).

app/code/QaisarSatti/HelloWorld/view/frontend/layout/helloworld_index_index.xml

<?xml version="1.0"?>
<!--/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email [email protected]
*
*/ -->
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceContainer name="content">
<block class="QaisarSatti\HelloWorld\Block\HelloWorld" name="HelloWorld" template="QaisarSatti_HelloWorld::HelloWorld.phtml"></block>
</referenceContainer>
</body>
</page>

Now your simple hello world module is complete. You can do following step to activate this module.

php bin/magento module:enable QaisarSatti_HelloWorld

You can see the output of module front page by http::yoururl/helloworld

Magento 2 create  and use helper

Using helper you can put your methods in there that you have no idea where to put them. For example if you want create the thumbnail of image you use the helper method. The method you don’t know where to put put in helper class. Now creating the helper and use of it.

Create Helper folder in module directory.



namespace QaisarSatti\HelloWorld\Helper

 

Now create the your helper class what name you want to put.In my case i will use Data file. Now the complete path will be.

namespace QaisarSatti\HelloWorld\Helper\Data.php



This file will be extend with.



 \Magento\Framework\App\Helper\AbstractHelper



Now create helper Data class.

 


<?php

/**

* Simple Hello World Module

*

* @category QaisarSatti

* @package QaisarSatti_HelloWorld

* @author Muhammad Qaisar Satti

* @Email [email protected]

*

*/


namespace QaisarSatti\HelloWorld\Helper;



use Magento\Store\Model\Store;



class Data extends \Magento\Framework\App\Helper\AbstractHelper

{



public function getTitle()

{

return  'First Hello World Module';

}

}

Now we will use helper method  in our block.

<?php

/**

* Simple Hello World Module

*

* @category QaisarSatti

* @package QaisarSatti_HelloWorld

* @author Muhammad Qaisar Satti

* @Email [email protected]

*

*/


namespace QaisarSatti\HelloWorld\Block;

class HelloWorld extends \Magento\Framework\View\Element\Template

{

protected $_helper;

public function __construct(

\QaisarSatti\HelloWorld\Helper\Data $_helper,

) {



$this->_helper=$_helper;



}

public function _prepareLayout()

{

parent::_prepareLayout();

$this->pageConfig->getTitle()->set($this->_helper->getTitle());

return $this;

}

}
