Showing number of comments on blog index page (or elsewhere)

If you want to show the number of comments for your blog posts somewhere else on the article page, or on the blog index page, you can add this code to your theme to display this information.

{% comment %} Ensure you add this in a file that has access to the {{ article }} object {% endcomment %}
{% assign replyComments = article.metafields.bb_comments.comment_list | map: 'replies' %}
{% assign parentComments = article.metafields.bb_comments.comment_list %}
{% assign totalComments = parentComments.size | plus: replyComments.size %}
{% if totalComments > 0 %}
<span>{{ totalComments }} comments on this article</span>
{% endif %}
