I am trying to modify a wordpress / MySQL function to display a little more information. I'm currently running the following query that selects the post, joins the 'postmeta' and gets the info where the meta_key = _liked

    function most_liked_posts($numberOf, $before, $after, $show_count) {
 global $wpdb;

    $request = "SELECT ID, post_title, meta_value FROM $wpdb->posts, $wpdb->postmeta";
    $request .= " WHERE $wpdb->posts.ID = $wpdb->postmeta.post_id";
    $request .= " AND post_status='publish' AND post_type='post' AND meta_key='_liked' ";
    $request .= " ORDER BY $wpdb->postmeta.meta_value+0 DESC LIMIT $numberOf";
    $posts = $wpdb->get_results($request);

    foreach ($posts as $post) {
     $post_title = stripslashes($post->post_title);
     $permalink = get_permalink($post->ID);
     $post_count = $post->meta_value;

     echo $before.'<a href="' . $permalink . '" title="' . $post_title.'" rel="nofollow">' . $post_title . '</a>';
  echo $show_count == '1' ? ' ('.$post_count.')' : '';
  echo $after;
    }
}

The important part being: $post_count = $post->meta_value;

But now I want to also grab a value that is attached to each post called wbphoto

How do I specify that $post_count = _liked and $photo = wbphoto

?
