Use case:

I have a custom post type of 'show' for a music venue. In the sidebar we want to display any related 'show' to the current one on single-show.php. They will be related by a custom taxonomy of 'genre'. I figured I could dump the custom taxonomy slugs for a post (might be more than one) into a variable then pass that variable into a custom query for the sidebar post.

Using get_the_term_list() works if there is a single taxonomy but if there are multiple it breaks (of course).

Any thoughts on how to get an array of the custom taxonomy slugs for a give post into a variable?

You can do something like the following:

$terms = get_the_terms( $post->id, 'genre' ); // get an array of all the terms as objects.

$terms_slugs = array();

foreach( $terms as $term ) {
    $terms_slugs[] = $term->slug; // save the slugs in an array

Gave me what I wanted. Unfortunately WordPress doesn't support queries for multiple custom taxonomies without some SQL hackery (LEFT JOIN...). – curtismchale Oct 4 '10 at 17:15
In case you are not aware, there is a plugin for querying multiple taxonomies: wordpress.org/extend/plugins/query-multiple-taxonomies – sorich87 Oct 4 '10 at 17:34
thanks I wasn't aware. it will be supported in 3.1 – curtismchale Oct 7 '10 at 1:09
