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";
}

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.
