Create a 'key' in the submission, something like... <input type="hidden" name="form_start" value="<?=date();?>" /> Check that "form_start" does not already exist in the database, or, even better that form_generation and form_user carries a unique key. Then check for a SQL collision. That would be superior to a select and an insert. Using linked relations and keys is your friend, as long as you have a database that supports these utilities.
