im learning symfony. I have a twig using twig extension and i found that i cannot call a function from other controller inside twig extension. so i have decide to use a service since the twig extension is using the service. so i tried to call a function from controller in the service and call the function from the service in the twig extension. Then, i have an error message that [Call to a member function has() on null], where $doct = $this->getDoctrine()->getManager(); in the controller.

this is the function in the controller that i'm trying to use

public function imagess(){

        return $temp;
    }

and this is the twig extension

use Eccube\Service\CartService;
class CartServiceExtension extends AbstractExtension
{
    /**
     * @var CartService
     */
    protected $cartService;

    public function get_image_route(){
        $t = $this->cartService->imagess();
        return $t;
        //return ['11', '12'];
    }

}

The line i got error in controller is

$doct = $this->getDoctrine()->getManager();

and when go inside getDoctrine()

trait ControllerTrait{

/**
     * Shortcut to return the Doctrine Registry service.
     *
     * @return ManagerRegistry
     *
     * @throws \LogicException If DoctrineBundle is not available
     *
     * @final
     */
    protected function getDoctrine()
    {
        if (!$this->container->has('doctrine')) {
            throw new \LogicException('The DoctrineBundle is not registered in your application. Try running "composer require symfony/orm-pack".');
        }

        return $this->container->get('doctrine');
    }

I don't know why but it seems has() function inside getDoctrine() returns null

how can i use the function from the controller so that i can pass the values of $custom_images into the twig?

CodePudding user response：

To get Doctrine in any controller action, you can do away with that function/trait entirely and just inject the EntityManagerInterface into your action.

For example:

class SomeCustomController extends AbstractController
{
    public function someControllerAction(Request $request, EntityManagerInterface $em): Response
    {
        // business logic
    }
}
