Add a breadcrumb to a view page?

Question

How can you just add a breadcrumb to views? Easy breadcrumb leaves out views. Views breadcrumb does not work correctly with Drupal 8. Is there a simple way with hooks?

EDIT 2: Maybe I mean something else?

In Drupal 7 (with custom breadcrumb) it looks like this: The view "Informationen" is called:

One node out of the view is called:

In Drupal 8 (with Easy breadcrumb) it looks like this: The view "Informationen" is called:

One node out of the view is called:

I hope I could explain the difference.

You should create a custom module (use core >= 8.3). Use this code as a base to start:

custom_breadcrumb.info.yml

name: 'Custom breadcrumbs'
description: 'Custom breadcrumbs implementation'
package: 'Custom'
# core: 8.x
type: module

version: '8.x-1.0'
core: '8.x'
project: 'custom_breadcrumb'
datestamp: 1443649740

custom_breadcrumb.services.yml

services:
  custom_breadcrumb.breadcrumb_views:
    class: Drupal\custom_breadcrumb\Breadcrumb\ViewsBreadcrumbBuilder
    tags:
      - { name: breadcrumb_builder, priority: 1 }

src/Breadcrumb/ViewsBreadcrumbBuilder.php

<?php

namespace Drupal\custom_breadcrumb\Breadcrumb;

use Drupal\Core\Breadcrumb\BreadcrumbBuilderInterface;
use Drupal\Core\Routing\RouteMatchInterface;
use Drupal\Core\Routing\LinkGeneratorTrait;
use Drupal\Core\StringTranslation\StringTranslationTrait;
use Drupal\Core\Link;

class ViewsBreadcrumbBuilder implements BreadcrumbBuilderInterface {
  use LinkGeneratorTrait;
  use StringTranslationTrait;

  /**
   * @inheritdoc
   */
  public function applies(RouteMatchInterface $route_match) {
    // This breadcrumb apply only for some views.
    $parameters = $route_match->getParameters()->all();

    if (isset($parameters['view_id'])) {

       $views_id = array(
         'VIEW_MACHINE_NAME_1',
         'VIEW_MACHINE_NAME_2',
       );

       if (in_array($parameters['view_id'], $views_id)) {
         return TRUE;
       }
       return FALSE;
    }
  }

  /**
   * @inheritdoc
   */
  public function build(RouteMatchInterface $route_match) {
    // Breadcrumbs set up (cache settings are so important!).
    $breadcrumb = new \Drupal\Core\Breadcrumb\Breadcrumb();
    $breadcrumb->addCacheContexts(["url"]);
    $breadcrumb->addCacheTags(["view_id:{$parameters['view_id']}"]);

    $parameters = $route_match->getParameters()->all();
    if (isset($parameters['view_id'])) {
      if ($parameters['view_id'] == 'VIEW_MACHINE_NAME_1') {
         $breadcrumb->addLink(Link::createFromRoute(t('VIEWS NAME 1'), '<none>'));
      }
      else if ($parameters['view_id'] == 'VIEW_MACHINE_NAME_2') {
        $breadcrumb->addLink(Link::createFromRoute(t('VIEWS NAME 2'), '<none>'));
      } 
    }

    // Reverse order for this to work!!!.
    $breadcrumb->addLink(Link::createFromRoute($this->t('Home'), '<front>'));
    return $breadcrumb;
  }
}

Remember to replace VIEW_MACHINE_NAME_1 and VIEW_MACHINE_NAME_2 with the machine name of your views. Also replace VIEWS NAME 1 and VIEWS NAME 2 with the breadcrumb title you want for each view.

Answer 2

• Go to Block layout page http://drupal-823.local/admin/structure/block
• Select Place block in your required region for eg : content.
• Search for breadcrumbs on the popup.
• Click Place block button

You can restrict the access to the view by configuring the pages section.
