Validating a CSRF Token
807+
-----------------------
808+
809+
Sometimes you want to use CSRF protection in an action where you don't want to use the
810+
Symfony Form component.
811+
812+
If, for example, you're doing a DELETE action, you can use the
813+
:method:`Symfony\\Bundle\\FrameworkBundle\\Controller\\Controller::isCsrfTokenValid`
814+
method to check the CSRF token::
815+
816+
if ($this->isCsrfTokenValid('token_id', $submittedToken)) {
817+
// ... do something, like deleting an object
818+
}

..versionadded::2.6
821+
The ``isCsrfTokenValid()`` shortcut method was introduced in Symfony 2.6.
822+
It is equivalent to executing the following code::
823+
824+
use Symfony\Component\Security\Csrf\CsrfToken;
825+
826+
$this->get('security.csrf.token_manager')->isTokenValid(new CsrfToken('token_id', 'TOKEN'));
