Drupal 8 print current breadcrumb trail with route title

Submitted by Julian Pustkuchen on 7. August 2019 - 20:38

Whao, that wasn't as easy as I thought. I wanted to print out the two top level breadcrumb elements, without "Home", with node title in a custom block. I tried it in many different ways but ran into surprises every time. So finally I'd like to share my code with you, if you should run into the same situation:

This is the part where the breadcrumbs and page title are retrieved:

$breadcrumbs = $this->breadcrumbManager->build($this->routeMatch)->getLinks();
$items = [];
if(!empty($breadcrumbs[1])){
$items[] = $breadcrumbs[1]->getText();
}
if(!empty($breadcrumbs[2])){
$items[] = $breadcrumbs[2]->getText();
}
// Fallback: Page title
$request = \Drupal::request();
$page_title = $this->titleResolver->getTitle($request, $this->routeMatch->getRouteObject());
if(!empty($page_title)){
$items[] = $page_title;
}
