多个控制器中的Symfony 3登录表单

Question

I followed this tutorial on how to build a login form in Symfony 3 and everything works fine.

However I'd like to use the same login form on multiple pages ("/" and "/login"). Unfortunately I can always get only one of these pages working based on how I configure the "login_path" and "check_path" in security.yaml.

So it's either

form_login:
                  login_path: login
                  check_path: login

or

form_login:
                  login_path: /
                  check_path: /

I've tried to add another firewall specifically for the login page to use both at once, but without success, my form on /login would then seem to submit and would redirect to default_target_path, but the user wouldn't be logged in. I've also tried to set the 'action' variable in the function createForm in controller to make the login form submit to /login even on the index page, but that didn't work either.

Any ideas on how to solve this issue ?

Answer 1

Have you tried creating a second entry with a different name? I'm not sure it will work, but technically different providers with different names are allowed. And there's no requirement they actually have different providers or different implementations.

security:
    # ...

    firewalls:
        main:
            # ...
            form_login:
                login_path: login
                check_path: login
        alternative
            # ...
            form_login:
                login_path: /
                check_path: /

You could redirect the user to the login page if they are not logged in.

//Assuming this is the action for the "/" route

public function indexAction($name)
{
  //If not logged in
  if (!$this->get('security.authorization_checker')->isGranted('IS_AUTHENTICATED_FULLY')) {
    return $this->redirectToRoute('/login');  
  }

  ...//If logged in
}

You could possibly just render the login page rather than redirecting.
