Get title of page

Question

When I get the title on some pages, I get an empty title like Home. The code I am using in my subscriber is the following one.

class HistorySubscriber implements EventSubscriberInterface {
  public static function getSubscribedEvents() {
    $events[KernelEvents::REQUEST][] = array('onResponse', 0);
    return $events;
  }

  public function onResponse($event) {
    $request = \Drupal::request();
    $route_match = \Drupal::routeMatch();
    $title = \Drupal::service('title_resolver')->getTitle($request, $route_match->getRouteObject());
  }
}

It is an issue? How I can fix it?

Answer 1

The following code can be used to change page title.

// Alter page title.
$request = \Drupal::request();
if ($route = $request->attributes->get(\Symfony\Cmf\Component\Routing\RouteObjectInterface::ROUTE_OBJECT)) {
  $route->setDefault('_title', 'Kontakt');
}

Answer 2

Try this

<?php
  $request = \Drupal::request();
  $title=t('Home');
  if ($route = $request->attributes->get(\Symfony\Cmf\Component\Routing\RouteObjectInterface::ROUTE_OBJECT) && !drupal_is_front_page()) {
    $title = \Drupal::service('title_resolver')->getTitle($request, $route);
  }

?>

this code return null in front page, then you should try to check if drupal_is_front_page then show another title

Use this code inside your function and You will get title of any page like term, node page...

public function getCurrentPageTitle() {
    $title = 'DEFAULT TITLE';
    $request = \Drupal::request();
    if ($route = $request->attributes->get(\Symfony\Cmf\Component\Routing\RouteObjectInterface::ROUTE_OBJECT)) {
      // For Taxonomy Term
      if (!empty($request->attributes->get('taxonomy_term'))) {
        $title = $request->attributes->get('taxonomy_term')->get('title')->value;
      }
      // For Node
      else {
        $node = \Drupal::routeMatch()->getParameter('node');
        if (!empty($node) && 'CONTENT_TYPE' === $node->bundle()) {
          $title = "CONTENT_TYPE_SPECIFIC_TITLE_SET";
          //$title = \Drupal::service('title_resolver')->getTitle($request, $route);
        }
        else {
          $title = \Drupal::service('title_resolver')->getTitle($request, $route);
        }
      }
    }
    return $title;
}
