# Query posts using author custom meta

 * I have a custom user meta field called ‘county’
    I have a custom post type called‘
   classes’
 * I want to query classes by all users whose ‘county’ meta is the same as the page
   ID.
 * Where I’m stuck is the post query. I’m using ‘author__in’ which expects an array
   of user ID’s. How do I do a user query here that will return an array of ID’s?
 *     ```
       $this_county = $post->post_name; //Use the ID of this page to determine which county we need
       $user_query = new WP_User_Query( array('meta_key' => 'county', 'meta_value' => $this_county) ); //Find users whose county is set to this county
       $args = array('author__in' => $user_query, 'post_type'=>'classes'); //Find classes by matched users
       ```

       $results = array();
       if ( ! empty( $user_query->results ) ) {
       	foreach ( $user_query->results as $user ) {
       		$results[] = $user->ID;
       	}
       } else {
       	echo 'No users found.';
       }
       $args = array('author__in' => $results, 'post_type'=>'classes'); //Find classes by matched users
       ```
