I am attempting to add some code to a hook_entity_view_alter() function to redirect the user to the homepage under a rare condition with RedirectResponse.

I understand the method to accomplish this is along these lines (taken from here):

$response = new Symfony\Component\HttpFoundation\RedirectResponse($url);
$response->send(); // don't send the response yourself inside controller and form.

My issue is that I am not sure how to format $url. Most articles on the topic, such as this one, suggest using \Drupal::url(), but this is deprecated in favour of Drupal\Core\Url. I would like to avoid using deprecated methods as much as possible, but am stuck at trying to figure out what the Drupal\Core\Url equivalent is to \Drupal::url('<front>'). I am not sure which methods to be using, and nothing I've tried with Url::fromUri() has worked.


Try using Url::fromInternalUri then instead of fromUri():


It specifically notes the use of front and none. But you can't pass the URL object or path tokens to RedirectResponse, as this is a Drupal construct. That class expects the following arguments:


string  $url        The URL to redirect to
integer $status     The response status code
array   $headers    An array of response headers

$url needs to be a string, so on your URL object, call ->toString() to get the URL.


  • I've tried Url::fromInternalUri(), but it's protected and can't be called from my function. I have also tried Url::fromUri('internal:/', array('absolute' => true))->toString() but this causes a browser crash from too many redirects. Url::fromUri('<front>')->toString() also does not work: "InvalidArgumentException: The URI '<front>' is invalid. You must use a valid URI scheme. in Drupal\Core\Url::fromUri() (line 280 of core\lib\Drupal\Core\Url.php)." – saramm1 Sep 6 '16 at 14:55
  • Oh, wait a sec, the test function I was using had something strange going on in it. $response = new Symfony\Component\HttpFoundation\RedirectResponse(Url::fromUri('internal:/', array('absolute' => true))->toString()); works. – saramm1 Sep 6 '16 at 15:04
  • @saramm1 $response = new Symfony\Component\HttpFoundation\RedirectResponse(Url::fromU‌​ri('internal:/', array('absolute' => true))->toString()); this has got some mistakes in it, can you please check and write the correct one? – Gaurav Rajdeo Sep 30 '17 at 12:07
