Get the route name of the current page

Question

The route name of the current page is available in page.html.twig? The page is generated by the default feedback form.

Answer 1

To get the current route name, use:

$route_name = \Drupal::routeMatch()->getRouteName();

You can add the current page's route name as a variable in your theme's ".theme" file. Add a _preprocess_page function like this, and clear the drupal cache.

/**
 * Implements hook_preprocess_page().
 *
 */
function mytheme_preprocess_page(&$variables) {
  $variables['route_name'] = \Drupal::routeMatch()->getRouteName();
}

Then you can access in page.html.twig like this:

{{ route_name }}

Note: \Drupal::routeMatch()->getRouteName() will sometimes return null.

If you are inside a class, to do things properly, you'll want to inject the route match service in the constructor and then call it this way:

$this->currentRouteMatch->getRouteName()

The constructor (and variable) will be like this:

  /**
   * The current route match.
   *
   * @var \Drupal\Core\Routing\RouteMatchInterface
   */
  protected $currentRouteMatch;

  /**
   * Constructs a new ThemeTestSubscriber.
   *
   * @param \Drupal\Core\Routing\RouteMatchInterface $current_route_match
   */
  public function __construct(RouteMatchInterface $current_route_match) {
    $this->currentRouteMatch = $current_route_match;
  }

If it's a service class, you'd then pass it into the service in the yaml file in your custom module:

services:
  mymodule.service:
    class: Drupal\mymodule\MyCustomService
    arguments: ['@current_route_match']

Another way to handle this is by using the Devel Module if you are developing locally.

1. Download and enable Devel
2. Log in as an administrator
3. Navigate to /admin/config/development/devel/toolbar
4. check "Current route info"
5. click Save configuration
6. Navigate to the url you are wanting the route information for
7. Click Devel in your toolbar above the admin menu
8. Click Current route info

If you are in a theme or situation where you can't find the admin toolbar or can't find the "Current route info" menu link, modify the url /devel/routes/item?path=/user/1 where /user/1 is the path that you are looking for path information for. It appears that this method will not work for pages that change routes based on get parameters... for example, ?_format=json or other custom routing like that.

Not for in a template, but to inspect the route: drush core:route:

drush core:route --path=/node/123/latest
drush core:route --path=/user/1

Ref: drush commands docs: core:route

Example:

$ drush core:route --path=/node/123/latest
name: entity.node.latest_version
path: '/node/{node}/latest'
defaults:
  _entity_view: node.full
  _title_callback: '\Drupal\Core\Entity\Controller\EntityController::title'
requirements:
  _entity_access: node.view
  _content_moderation_latest_version: 'TRUE'
  node: \d+
options:
  _content_moderation_entity_type: node
  parameters:
    node:
      type: 'entity:node'
      load_latest_revision: true
      converter: paramconverter.entity
  _access_checks:
    - access_check.entity
    - access_check.latest_revision
