For Symfony 5, you can use out of the box functionalities to create login and registration forms.
Using Symfony\Component\Security\Guard\GuardAuthenticatorHandler is key point.
You can use GuardAuthenticatorHandler in registration controller after successful registration. It logs in user and redirects to page defined in onAuthenticationSuccess from LoginFormAuthenticator.
Below, I added some code snippets.
<?php
namespace App\Controller\Login;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Http\Authentication\AuthenticationUtils;
class LoginController extends AbstractController
{
/**
* @Route("/login", name="app_login")
*/
public function login(AuthenticationUtils $authenticationUtils): Response
{
// get the login error if there is one
$error = $authenticationUtils->getLastAuthenticationError();
// last username entered by the user
$lastUsername = $authenticationUtils->getLastUsername();
return $this->render('security/login.html.twig', ['last_username' => $lastUsername, 'error' => $error]);
}
/**
* @Route("/logout", name="app_logout")
*/
public function logout()
{
throw new \LogicException('This method can be blank - it will be intercepted by the logout key on your firewall.');
}
}
