Add a message on forums with no topics yet

I think you could do this in forums.html.twig if the topics variable was empty

{% if topics is empty %}
<p>Hey, no topics exist yet, please check back soon thanks 😎</p>
{% else %}
// existing twig code
{% endif %}

I fiddled a bit with forums.html.twig before posting. The problem is the message equally shows up on containers where topics exist in some of the forums and some forums are empty.

You might be able to check term.forum_container.value or term.get('forum_container').value

If its true, then its a container so you could skip the message.

Oh, and if that doesn't work, you can implement hook_preprocess_forums() in your theme and create an 'is_container' flag.

something like this

function YOURTHEME_preprocess_forums(&$variables) {
  $variables['is_container'] = $variables['term']->forum_container->value;
}

Where YOURTHEME is your theme name and this file goes in your .theme file.

You would then have access to is_container in the twig file.

I created the is_container flag but problem was the /forum path which returned 0 as though it were a forum and all board was hidden.

I tried to exclude the path in the preprocess function this way,

 function custom_module_preprocess_forums(&$variables) {
    $current_path = \Drupal::service('path.current')->getPath();

    if ($current_path != '/forum') {
      $variables['is_container'] = $variables['term']->forum_container->value;
      }      
  }

and then this on the template file,

{% if topics is empty and is_container == '0' %}
<p>Hey, no topics exist yet, please check back soon thanks 😎</p>
{% else %}
  {% if forums_defined %}
    <div class="forum">
      {{ forums }}
      {{ topics }}
      {{ topics_pager }}
    </div>
  {% endif %}
{% endif %}

It is working this way.

Thanks.

Nice work!

I think it's worth adding the is container and an is root variable to the module itself but I want to wait until we get it removed from core first

Postponing for that

Okay.
