Taxonomy Custom Controller

The Taxonomy Custom Controller module is a default Taxonomy Term entity canonical controller override with event.

It will help you to subscribe to event and change content of term page. You can change it for specific vocabularies, or specific term with conditions you want!

USAGE

Simple example:

/**
 * Provides subscriber for term page build.
 */
class TermPageBuildSubscriber implements EventSubscriberInterface {

  /**
   * {@inheritdoc}
   */
  public static function getSubscribedEvents() {
    return [
      TaxonomyCustomControllerEvents::PAGE_BUILD => 'onTermPageBuild',
    ];
  }

  /**
   * Reacts on term page build.
   *
   * @param \Drupal\taxonomy_custom_controller\Event\TermPageBuildEvent $event
   *   The event.
   */
  public function onTermPageBuild(TermPageBuildEvent $event) {
    $taxonomy_term = $event->getTaxonomyTerm();
    if ($taxonomy_term->bundle() != 'tags') {
      return;
    }

    // Adds term description on top of the default views.
    $build = [];
    if (!$taxonomy_term->get('description')->isEmpty()) {
      $build['description'] = [
        '#type' => 'container',
        '#attributes' => [
          'class' => ['wrapper-for-custom-added-description'],
        ],
        'description' => $taxonomy_term->get('description')->view(),
      ];
    }
    $build['view'] = views_embed_view('taxonomy_term', 'page_1', $taxonomy_term->id());
    $event->setBuildArray($build);
  }

}
