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.
