I need to redirect all the pages for a content type to a custom URL in Drupal 8.

I used to do this in Drupal 7 by implementing hook_init() with the function drupal_goto() or by using the Rules module. Unfortunately both hook_init() and drupal_goto() are removed in Drupal 8, and the Rules module is not stable yet, and I can't figure out how to do it in Drupal 8.

How can I achieve what I am trying to do?

    You should look at the Change Records to learn about alternatives to removed functions/hooks. Specifically drupal.org/node/2013014 has an example extremely similar to what you are trying to do. – mradcliffe May 27 '16 at 1:47
  • Thanks @mradcliffe, actually I already tried to add Event Subscriber like in drupal.org/node/2013014 but the problem was in detecting the content type of the node in the node page. anyway, I managed to solve this issue and I added an answer :) – Aghiad May 27 '16 at 21:50

Here is how I managed to solve this issue, based on the example in drupal.org/node/2013014:

I registered Event Subscriber in my_redirect_module.services.yml file:

   services:
     my_redirect_module_event_subscriber:
     class: Drupal\hbmsu_redirect\EventSubscriber\MyRedirectModuleSubscriber
     tags:
       - {name: event_subscriber}

and then in the file my_redirect_module/src/EventSubscriber/MyRedirectModuleSubscriber.php

I added this code:

  namespace Drupal\my_redirect_module\EventSubscriber;

  use Symfony\Component\HttpFoundation\RedirectResponse;
  use Symfony\Component\HttpKernel\KernelEvents;
  use Symfony\Component\HttpKernel\Event\GetResponseEvent;
  use Symfony\Component\EventDispatcher\EventSubscriberInterface;

  class MyRedirectModuleSubscriber implements EventSubscriberInterface {

      public function checkForRedirection(GetResponseEvent $event) {

          $baseUrl = $event->getRequest()->getBaseUrl();
          $attr = $event->getRequest()->attributes;
          if(null !== $attr &&
             null !== $attr->get('node') &&
             $attr->get('node')->get('type')->getString() == 'my_content_type') {
              $event->setResponse(new RedirectResponse($baseUrl.'/some_internal_url_path'));
          }
      }

      /**
       * {@inheritdoc}
       */
      static function getSubscribedEvents() {
          $events[KernelEvents::REQUEST][] = array('checkForRedirection');
          return $events;
      }

  }

in checkForRedirection function, I'm checking if the page is for a node with the content type my_content_type, then redirect to the page mywebsite.com/some_internal_url_path

If you need to redirect from a custom form or an existing form (login, logout,...)=> (I assume this is what you want as you ask redirecting from a content type, I think you mean "after editing a content type");

then you can use

$form_state->setRedirect('user.page');

you can add this code in your form_alter, form_submit functions of your content type that you need to redirect

You can find some doc: https://api.drupal.org/api/drupal/core!lib!Drupal!Core!Form!FormSubmitterInterface.php/function/FormSubmitterInterface%3A%3AredirectForm/8.2.x

Like this example:

$form_state->setRedirect('entity.node.canonical',
 array('node' => 123),
  array(
    'query' => array(
      'foo' => 'bar',
    ),
    'fragment' => 'baz',
  ),

));

  • Thanks @Baud, actually in my case I don't have form submission. I wanted to redirect all the node pages for certain content type to another page created with Views has a list of all these contents. anyway, I found the solution for this issue and I added an answer here :) – Aghiad May 27 '16 at 22:09

You can use Rabbit hole and Token modules. With Rabbit hole you will be able to set a Page Redirect for the content type, and with Token you can choose a field where users will be redirected when they try to access to a node.

  • If the nodes need to be secure, rabbit hole is the better option. It will block the node on more levels than what you could do with only using a Subscriber. – coderama Jan 5 '19 at 2:42
