Using classes in PrestaShop 1.7 Symfony controller

In blog Override a Symfony Controller we discuss about overriding Symfony controllers available in PrestaShop. Now suppose, we need to use classes in PrestaShop 1.7 Symfony controller, how we do that?

In this blog, we are going to learn how to use methods and function define in PrestaShop core classes, module main class file or from module classes.

There are following ways to use classes in overridden Symfony controllers :

• Use Method
• By Module Instance method

Let’s understand the entire process to override with the help of taking an example as given below.

Use Method

Just add below lines at the top of the Symfony Controller say DemoController.php file after namespace to use PrestaShop classes.

namespace Webkul\Controller\Admin;

use Configuration;
use ModuleName;
use Student;

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

class DemoController extends FrameworkBundleAdminController
{
     $objConf = new Configuration();
<strong>                 or</strong>
     $objMod = new ModuleName();
<strong>                 or</strong>
     $objStu = new Student();

Here,
use Configuration; loads core Configuration class.
use ModuleName; load module main class file.
use Student; load Student class inside module classes folder.

Module Instance Method

This method is only used to load module main class function. Load module instance in Symfony controller as below :

$module = Module::getInstanceByName('modulename');
if (method_exists($module, 'getNewFunction')) {
    $result = $module->getNewFunction();
}

In this example we load module main class file and it’s method getNewFunction() by creating module instance.

We can also implement use classes in PrestaShop 1.7 Symfony controller if we need to load method from other modules.

This is how we can use the classes in Symfony Controller in our module.

That’s all.
