Overriding Controllers¶

Extending base Controller¶

If you want to modify the controller or add your custom actions, you can do so by defining a new controller class. By extending resource controller, you also get access to several handy methods. Let’s add to our custom controller a new method to recommend a product:

<?php

// src/Acme/ShopBundle/Controller/ProductController.php

namespace Acme\ShopBundle\Controller;

use Sylius\Bundle\ResourceBundle\Controller\ResourceController;
use Symfony\Component\HttpFoundation\Request;

class ProductController extends ResourceController
{
    public function recommendAction(Request $request, $id)
    {
        $product = $this->findOr404(array('id' => $id)); // Find product with given id or return 404!
        $product->incrementRecommendations(); // Add +1!

        $this->persistAndFlush($product); // Save product.

        return $this->redirect($this->generateUrl('acme_shop_homepage'));
    }
}

You also need to configure your controller class in app/config/config.yml.

# app/config/config.yml

sylius_product:
    driver: doctrine/orm
    classes:
        product:
            controller: Acme\ShopBundle\Controller\ProductController

That’s it! Now sylius.controller.product:recommendAction is available. You can use it by defining a new route.

# app/config/routing.yml

acme_shop_product_recommend:
    path: /products/{id}/recommend
    defaults:
        _controller: sylius.controller.product:recommendAction

What has happened?

• Parameter sylius.controller.product.class contains Acme\\Bundle\\ShopBundle\\Controller\\ProductController.
• Controller service sylius.controller.product is using your new controller class.
