Override Existing Symfony Controller in PrestaShop 1.7

In this blog, we are going to learn how to override existing Symfony Controller method available in PrestaShop back-office.

If you are looking for remap the route method check this blog. In PrestaShop 1.7.7, back-office controllers are registered as services, like all other services using services.yml file.

How to use override existing Symfony Controller method

Follow the given folder structure for module same as in the image :

Here, we will show you an example of page Improve -> Design -> CMS Pages, which register in PrestaShop as service ID "PrestaShopBundle\Controller\Admin\Improve\Design\CmsPageController".

Let’s understand the entire process to override with the help of taking the example above.

Step 1:

In composer.json file write the code as given below :

{
    "name": "yourname/yourmodulename",
    "license": "AFL-3.0",    
    "autoload": {
        "psr-4": {"Namespace\\": "src/"},
        "classmap": ["yourmodule.php"],
        "config": {"prepend-autoloader": false},
        "type": "prestashop-module"
    }
}

Step 2 :

You can write your own services using the YAML configuration file. In your module, you can create your own services as shown here.

Create yourmodule/config/services.yml

services:
    'PrestaShopBundle\Controller\Admin\Improve\Design\CmsPageController':
     class: Webkul\Controller\Admin\DemoController

Here services forward a request to your module controller written in class: Namespaces\Controller\Admin\DemoController.

Now, whenever Symfony forwards a request to the Core Symfony Controller "PrestaShopBundle\Controller\Admin\Improve\Design\CmsPageController", it will be forwarded to the "DemoController" instead.

Step 3 :

yourmodule.php

declare(strict_types=1);

// Needed for installing process 
require_once __DIR__ . '/vendor/autoload.php';

class YourModule extends Module
{

After that, run the below command in the module folder which loads namespace(Namespace).
$ composer dumpautoload

Step 4 :

src/Controller/Admin/DemoController.php 

declare(strict_types=1);

namespace Namespace\Controller\Admin;

use PrestaShopBundle\Controller\Admin\FrameworkBundleAdminController;
use Symfony\Component\HttpFoundation\Request;

class DemoController extends FrameworkBundleAdminController
{

We don’t recommend this method until you want to rewrites the whole controller functionality.

Step 5 :

Rendering your own twig in the new controller, add
/yourmodule/views/templates/admin/index.html.twig

public function indexAction(Request $request)
{
   return $this->render(
     '@Modules/yourmodule/views/templates/admin/index.html.twig'
   );
}

This is how we can override the existing Core Symfony Controller in PrestaShop to the new controller from your own module.

Stay tuned, we will release Decorate Method for overriding controller soon.

That’s all.
