Sometimes you want to return a 404 (Not Found) response, because the requested resource does not exist. Symfony allows you to do so by throwing a NotFoundHttpException
.
The Symfony base Controller exposes a createNotFoundException
method which creates the exception for you:
public function indexAction()
{
// retrieve the object from database
$product = ...;
if (!$product) {
throw $this->createNotFoundException('The product does not exist');
}
// continue with the normal flow if no exception is thrown
return $this->render(...);
}
