A WordPress taxonomy is a way to organize groups of posts and custom post types. By default, WordPress comes with two taxonomies called categories and tags. However, if you are using a custom post type, then you may need custom taxonomies.
There are two types of custom taxonomies.
- Hierarchical Taxonomy (works like categories)
- Non-Hierarchical Taxonomy (works like tags)
For instance, you can create a custom post type called ‘Quotes’ and sort it using custom taxonomies ‘Topics’ and ‘Writers’. Each topic and each writer is a term.
What if you want to display a list of topics or a list of writers with their posts number?
WordPress has pre-made categories and tag cloud widget. But there is no widget to show custom taxonomy terms list.
Categories widget’s output will be something like this:
How can we achieve similar result for custom taxonomies?
Add following code to the template where you want to show the list:
$custom_cats = get_terms('quote-writer');
echo '<ul>';
foreach ( $custom_cats as $term ) {
$term_link = get_term_link( $term);
echo '<li><a href="'.$term_link.'">'.$term->name . ' (' . $term->count . ')</a></li>';
}
echo '</ul>';Change ‘quote-writer‘ to your custom taxonomy name. This works for both hierarchical and non-hierarchical taxonomy.
You can even use ‘category‘ or ‘post_tag‘ here to get the list of categories or tags.
Let me know if this works for you or not.

How would you add a custom field already created?
For example, you create a custom field with afc called “pdf” and you want the link to appear below. How do you make it work?
Because I have been tested with:
$ pdf = get_field (‘pdf’, $ term-> name. ‘_’. $ term-> term_id);
And with:
$ pdf = get_field (‘pdf’, $ term);
but I can’t make it work.
Test following code and if it doesn’t work, reach ACF support.
$term = get_queried_object();$pdf = get_field('pdf', $term);
