php - What should be the default value for $security?
Get the solution ↓↓↓
I'm working on this method:
public function loginAction(Request $request, Security $security)
{
$session = $request->getSession();
$session->remove('admin_project_id');
if ($security->has(Security::AUTHENTICATION_ERROR)) {
$error = $request->attributes->get(Security::AUTHENTICATION_ERROR);
} else {
$error = $session->get(Security::AUTHENTICATION_ERROR);
$session->remove(Security::AUTHENTICATION_ERROR);
}
return $this->render('PDOneBundle:Login:index.html.twig',
array_merge($this->defaultViewParams(), array(
'last_username' => $session->get(Security::LAST_USERNAME),
'error' => $error,
'include_sidebar' => false,
)
)
);
}
But I got this error when it's called:
Controller "GroupDCA\PDOneBundle\Controller\LoginController::loginAction()" requires that you provide a value for the "$security" argument (because there is no default value or because there is a non optional argument after this one).
What should be the default value for that argument? Is the way I'm using right?
Answer
Solution:
first of all, you don't need to pass $security as an argument. The line where you use security, you actually have to access $request and look its attributes for an error.
Secondly, I saw you tagged the question as symfony 2.7 and since version @2.6 a new, short way of login was introduced:
public function loginAction(Request $request)
{
$authenticationUtils = $this->get('security.authentication_utils');
// 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',
array(
// last username entered by the user
'last_username' => $lastUsername,
'error' => $error,
)
);
}
