Question

symfony

Need to do something like this?

public function registration()
    {
        $user = new User();
        $form = $this->createForm(RegistrationFormType::class, $user);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            // encode the plain password
            $user->setPassword(
                $passwordEncoder->encodePassword(
                    $user,
                    $form->get('plainPassword')->getData()
                )
            );
            $userType = $form->get('type')->getData();
            var_dump($userType); exit;

            $entityManager = $this->getDoctrine()->getManager();
            $entityManager->persist($user);
            $entityManager->flush();

//            // generate a signed url and email it to the user
//            $this->emailVerifier->sendEmailConfirmation('app_verify_email', $user,
//                (new TemplatedEmail())
//                    ->from(new Address('[email protected]', 'Andrii'))
//                    ->to($user->getEmail())
//                    ->subject('Please Confirm your Email')
//                    ->htmlTemplate('registration/confirmation_email.html.twig')
//            );

            // do anything else you need here, like send an email
            $formView = $form->createView();
            return $guardHandler->authenticateUserAndHandleSuccess(
                $user,
                $request,
                $authenticator,
                'main' // firewall name in security.yaml
            );
        }
    }
