Let's say I have one custom taxonomy called "movies" and another called "actors". How to I link those two taxonomies so as to be able to determine which actors play in such and such movie, or which movie does such and such actors plays in ?

(I don't want to use custom post types, only taxonomies)

You want to be able to click an actor and have it list all of the movies he plays in? – xLRDxREVENGEx Jun 3 '11 at 17:36
Yes and vice versa (click on a movie and have it list all of the actors it features) – Mike Jun 3 '11 at 17:51
What types of posts will these taxonomies be used with? – tnorthcutt Jun 3 '11 at 18:34

Why are you unwilling to use post type? In what you are describing movies, if not actors, really should be a post type. Perhaps you might get a better answer if we understood what you were actually trying to accomplish... – mattrepublic Jun 3 '11 at 21:45

@Mike There is no direct way to link two custom taxonomies in the fashion that you are looking for. You can indirectly link two taxonomies by creating a taxonomy archive page for one taxonomy and inserting a loop for the other taxonomy in that template. It would be much simpler for you to use a standard post with a Quote post format. – mattrepublic Jun 5 '11 at 14:14

the func to add a post to a taxonomy can be used here. 

            wp_set_post_terms($post->ID, $term->term_id, $taxonomy, true);

So in your case to move 'actors' to 'movies', get the actor (post_id) and call:

wp_set_post_terms($post_id, $term_id, "movies", true);

Now post_id is in two taxonomies, the original 'actors' and the new 'movies'

hope this helps ;)
