RE: [PHP] Reservation technique

Hi Roger, I think you need to check out the BETWEEN operator in MySQL (assuming you're using MySQL? Look for the equivalent operator in whatever db platform you're using, if otherwise). Essentially what you're looking to do is find out if either the start time or the end time of the new booking falls BETWEEN the start time or the end time of an existing booking. If either of them does, it's safe to assume there's a booking conflict. Much warmth, Murray http://www.planetthoughtful.org Building a thoughtful planet, One quirky comment at a time.
