Template to list categories in custom taxonomy

Question

I refer to this post where I have just taken my code from: How to display a listing template of a certain taxonomy?

I am trying to create a page template that will list all categories in "servicecats" taxonomy which is linked to the custom post-type "Services".

In the page template I have used the code taken from the link above:

<?php

        $taxonomy     = 'servicecats';
        $orderby      = 'name'; 
        $show_count   = 0;      // 1 for yes, 0 for no
        $pad_counts   = 0;      // 1 for yes, 0 for no
        $hierarchical = 1;      // 1 for yes, 0 for no
        $title        = '';

        $args = array(
          'taxonomy'     => $taxonomy,
          'orderby'      => $orderby,
          'show_count'   => $show_count,
          'pad_counts'   => $pad_counts,
          'hierarchical' => $hierarchical,
          'title_li'     => $title
        );

    ?>
<?php wp_list_categories( $args ); ?>

When I view the page, it just says "No categories" although I do have 4 set up, the taxonomy and post-type are both hierarchical.

Any suggestions? Thanks

I managed to sort this using:

<?php $category_ids = get_all_category_ids(); ?>
      <?php
      $args = array(
         'orderby' => 'slug',
         'parent' => 0,
        'taxonomy' => 'servicecats'
      );
      $categories = get_categories( $args );
      foreach ( $categories as $category ) {
         echo '<li><img src=""/><a href="' . get_category_link( $category->term_id ) . '" rel="bookmark">' . $category->name . '' . '' . $category->description . '</a></li>';
      }
     ?>

Would still like to know how to also show the empty categories though if anyone could offer advice on this?

Just use 'hide_empty' and set it to false as it's true per default.

wp_list_categories( array(
    'hide_empty' => false,
) );

The code in question works and I can only think of two reasons why it fails

• Wrong taxonomy name supplied

• The terms assigned to taxonomy is empty

I would suggest that you get wp_list_categories() working as it is faster and less resource intensive than get_categories()

To get empty terms, simply add the hide_empty parameter to your arguments and set it to 0
