Passing data between pages

I have a simple script that creates a series of links based on the results of a query. As you can see from the code below, I am currently appending the query info to the URL, but I don't believe this to be an ideal solution. <? $query = "SELECT * FROM categories ORDER BY cat_id"; $result = mysql_query( $query ); while ( $row = mysql_fetch_array( $result ) ) print "<a href=\"display_items.php?cat_id=".$row['cat_id']."\">".$row['cat_name']."</a><br />\n"; ?> A search of numerous online resources and my collection of books leads me to believe that I have two basic options: the first is to use a form, which I am unsure of how to do with text links. The second is to implement sessions, which I feel may be overkill. Overkill, that is, unless it's my only option. ;P I look forward to all of your suggestions. I'm sure I'm overlooking something that should otherwise be easy, so I apologize in advance. Thanks a lot. Edward Dudlik Becoming Digital www.becomingdigital.com
