List Categories for Custom Post Types - WordPress

Question

I'm using custom poshttp://wordpress.stackexchange.com/badges/66/outspoken?userid=736t types in WordPress 3.0 (now 3.0.1) to setup a custom directory system, but can't seem to find how to list out the categories under the custom taxonomy similar to how you'd use the wp_list_categories for normal posts. Anyone know how you'd do this on a page? Thanks!

I've seen suggestions for options like the following, but have had no luck when popping them in there:

<?php
//list terms in a given taxonomy using wp_list_categories  (also useful as a widget)
$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
$taxonomy = 'genre';
$title = '';

$args = array(
  'orderby' => $orderby,
  'show_count' => $show_count,
  'pad_counts' => $pad_counts,
  'hierarchical' => $hierarchical,
  'taxonomy' => $taxonomy,
  'title_li' => $title
);
?>
<ul>
<?php
wp_list_categories($args);
?>
</ul>

Answer 1

Are you sure you called register_taxonomy before you called wp_list_categories? register_taxonomy should be called in the init action hook, your template code (I assume you use it there) after that.

Answer 2

you have to post some content associated to your taxonomy[custom taxonomy] first! I used you code in my project and works like a charm!

If you need something more like ordering, filtering and pagination, see my post : http://geryit.com/blog/2011/03/wordpress-custom-post-types/
