How to Manually Validate a CSRF Token in a Controller

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

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