This is a DB question not a PHP question, plus you haven't told us what database and table type you're using. However, you can either delete the relationship yourself (using PHP code), write a trigger to do it semi-manually, or set your database up properly with a foreign key constraint. Assuming you're using MySQL and your table type supports foreign keys, see http://dev.mysql.com/doc/refman/5.1/en/innodb-foreign-key-constraints.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
