I've created a facet block according to this example Programatically render a block in a twig template

I've created the facet block as follows:

$variables['block_output'] = Drupal::service('plugin.manager.block')->createInstance("facet_block:topic")->build();

That works great, but I'm missing the block template itself on my page (the block around the facet links output). I need a custom suggestion for this block to format it. Unfortunately, the hook_theme_suggestions_alter() doesn't detect this block. How can I add a file name suggestion?

Thank you!

  • try \Drupal::entityTypeManager()->getViewBilder('block')->view($block, $view_mode). Also you need the block entity, not plugin. Block entity basically bundles the plugin and configuration for it together. Discard previous, just entity_load('block', $id)->view($view_mode) should work. – user21641 Mar 23 '16 at 14:40
  • Yes, that works, assuming that you have a block. See drupal.stackexchange.com/questions/153184/…. build of the plugin just contains the content of the block. Page manager uses block plugins too and has its own templates. You could build a structure similar to what BlockViewBuilder does or you could simply add your markup around it yourself in your template. – Berdir Mar 23 '16 at 18:47
  • Thank you for your answers. Berdir, what do you mean with "build a structure similar to what BlockViewBuilder does" exactly? Can you make a example? Thank you very much! – marco-s Mar 30 '16 at 7:16
