There are many ways to store hierarchical data in a db, the adjacency method that you're using is simple to use, but slow and complex to execute when there are many parent/child relationships. There are whole books on this subject, but http://stackoverflow.com/questions/192220/what-is-the-most-efficient-elegant-way-to-parse-a-flat-table-into-a-tree/192462#192462 has a good explanation on some other ways of storing hierarchical trees in MySQL and how to maintain them through SQL. Maybe you could log the number of db calls you're making, as this might show you how much is being done by the db just to show the full tree. Thanks, Ash Thanks, Ash
