Drupal7 update hook dependencies

Posted on by

You sometimes find that update hooks run in an unwanted order that affects their behaviour or creates errors and makes your site crash. You can override this and specify the order that you want with the following hook in your .install file.

 function new_module_update_dependencies() {
  // Run new_module update after old_module update.
  $dependencies['new_module'][7001] = array(
    'old_module' => 7000,
  );
 
  return $dependencies;
 }

Drupal 8 is admin path

Posted on by

To check the path of the current page:

$is_admin = \Drupal::service('router.admin_context')->isAdminRoute();

to check an arbitrary path, you need to create a Request object and obtain its matching Route:

use Symfony\Component\HttpFoundation\Request;
use Symfony\Cmf\Component\Routing\RouteObjectInterface;

$path = '/node/1';
$request = Request::create($path);

$route_match = \Drupal::service('router.no_access_checks')->matchRequest($request);
$route = $route_match[RouteObjectInterface::ROUTE_OBJECT];
$is_admin = \Drupal::service('router.admin_context')->isAdminRoute($route);
