Holding links in a database

Hi, I have a table in my database that holds links for individual pages on my site: mysql> DESCRIBE Page_Links; +-----------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------+--------------+------+-----+---------+----------------+ | Link_ID | int(11) | | PRI | NULL | auto_increment | | PHP_SELF | varchar(100) | | | | | | Action | varchar(100) | | | | | | Link | varchar(255) | | | | | | Link_Text | varchar(100) | | | | | +-----------+--------------+------+-----+---------+----------------+ 5 rows in set (0.00 sec) The links that appear on each page depend on PHP_SELF i.e./users/index.php and $_GET[action] variable i.e. add_user. This all works well until there is a problem with the form validation, for example if I am on the add_user.php page and I click to add a user I am taken back to the users list, the action is insert_user and I display the links accordingly. However if there is a problem with the submission i.e. the user leaves a field blank then they are redirected to the add_user.php page, the action is still insert_user but I would not want the same links to appear on this page. Any help on this matter would be greatly appreciated
