Wordpress Custom Type permalink containing Taxonomy slug
After more searching I managed to create fairly elegant solution using the custom_post_link filter.
Let's say you have a project Custom Type with a client Taxonomy. Add this hook:
function custom_post_link($post_link, $id = 0){ $post = get_post($id); if(!is_object($post) || $post->post_type != 'project') { return $post_link; } $client = 'misc'; if($terms = wp_get_object_terms($post->ID, 'client')) { $client = $terms[0]->slug; //Replace the query var surrounded by % with the slug of //the first taxonomy it belongs to. return str_replace('%client%', $client, $post_link); } //If all else fails, just return the $post_link. return $post_link;}add_filter('post_type_link', 'custom_post_link', 1, 3);Then, when registering the Custom Type, set the rewrite arg like this:
'rewrite' => array('slug' => '%client%')I guess I should have dug deeper before asking, but at least we have a complete solution now.
