Validating a CSRF Token
815+
-----------------------
816+
817+
Sometimes, you want to use CSRF protection in an action where you don't want to
818+
use the Symfony Form component. If, for example, you're doing a DELETE action,
819+
you can use the:method:`Symfony\\Bundle\\FrameworkBundle\\Controller\\Controller::isCsrfTokenValid`
820+
method to check the CSRF token::
821+
822+
if ($this->isCsrfTokenValid('token_id', $submittedToken)) {
823+
// ... do something, like deleting an object
824+
}
825+
826+
..versionadded::2.6
827+
The ``isCsrfTokenValid()`` shortcut method was introduced in Symfony 2.6.
828+
It is equivalent to executing the following code:
829+
830+
..code-block::php
831+
832+
use Symfony\Component\Security\Csrf\CsrfToken;
833+
834+
$this->get('security.csrf.token_manager')
835+
->isTokenValid(new CsrfToken('token_id', 'TOKEN'));
