You will need a second query to ask for all the children of the parent: $peer_query = "select id as child_id, title from meta_data where pid = $pid"; $peers = mysql_query($query) or error_log(mysql_error()); while (list($child, $child_title) = mysql_fetch_row($peers)){ echo "$child_title ($child)<BR>\n"; } >P.P.P.S.

I'm saying: Don't do that. Don't use * in this first query. In *ANY* query, specify *exactly* which columns you need. You'll be a lot less confused by your data when you start forcing yourself to be more precise in your code about what you want. *CHANGE* the line above to: $query = "select id, pid, title, description, keywords from meta_data where page_name = '$fn'"; Then, after you have the $pid, add in the stuff I wrote above. -- Like Music? http://l-i-e.com/artists.htm
