You want to make sure only valid checkboxes are checked.For a single checkbox, ensure that if a value is supplied, it's the correct one.Code: [Select]$result = mysql_query("SELECT * FROM course") or die(mysql_error()); if ($result) Help needed purely on php codes.

Then, use array_intersect( ) to ensure that the set of submitted values is contained within the set of acceptable values, as shown in Example 9-15. Checkboxes have the same issues with default values as do radio buttons.

The session usually lives for 24 minutes after the last HTTP request. I just realized that Sniper Code Sheva did post something pretty similar to Ray (but I don't think it would have worked in it's current state) and I should award that points instead of the j Query post!

Please could admin help me out and allow me to change the points assignment.

If a value isn't supplied for the checkbox, then the box wasn't checked.
