I am making a basic application for booking Water Skiing sessions. The administrator can log in and add session times, i.e. 01 August 2010 09:00 for members to book.
Obviously as the administrator add’s times, I don’t want them to be able to add the time twice
So I have a table with fields
skidate, skitime and status , and a form with fields skidate, skitime and status
How can I make the form check on the skidate and skitime to see if it’s already there…
Thanks in advance
