How to Manually Validate a CSRF Token in a ControllerΒΆ

Sometimes, you want to use CSRF protection in an action where you do not want to use the Symfony Form component. If, for example, you are implementing a DELETE action, you can use the isCsrfTokenValid() method to check the validity of a CSRF token:

1
2
3
4
5
6
public function deleteAction()
{
    if ($this->isCsrfTokenValid('token_id', $submittedToken)) {
        // ... do something, like deleting an object
    }
}

New in version 2.6: The isCsrfTokenValid() shortcut method was introduced in Symfony 2.6. It is equivalent to executing the following code:

1
2
3
4
use Symfony\Component\Security\Csrf\CsrfToken;

$this->get('security.csrf.token_manager')
    ->isTokenValid(new CsrfToken('token_id', 'TOKEN'));
