Hello! I decided to make a page for visitors to the canteen, on the page a map of seats, approximately 60x60 (tables in 30 rows, each row with 60 seats). One place is one square. I decided to use the map area, sketched out a simple database, I keep the coordinates of the places that the visitor chose there (such a kind of reservation), i.e. 4 numbers. Now the question arose how to forbid visitors to book NOT FREE seats: I show the occupied places with the maphilight script (backlight), but in order not to let book, you need some kind of filter or something else?
