This example is for an employee directory. We created a custom post type called “employee”. For that custom post type we created two custom taxonomies – “type” and “department”. Lets say we want to find employees in the technology department that are programmers.
$args=array( 'post_type' => 'employee', 'post_status' => 'publish', 'posts_per_page' => -1, 'caller_get_posts' => 1, 'order' => 'ASC', 'orderby' => 'title', 'type' => 'programmer', 'department' => 'technology' ); query_posts( $args ); // loop it
Hopefully this helps if you are looking to query multiple custom taxonomies from custom post types in WordPress. Have questions? Let us know in the comments!
