My booking system currently allows users to delete bookings at any time. The system should restrict the users from deleting bookings at a certain time for instance 24 hours before the booking date. Users should only be able to delete bookings 48 prior to booking date. Is there any way of doing this.

current sql statement

$query1="DELETE from bookings1 where booking_id='$id'";

$results = $mysqli->query($query1);

would i need to use some function or something

Yes, you need to add some logic before calling delete.

IMHO the database would be the best place for this logic since the data is then safe regardless what application tries to modify the data.

In order to do that, I'd write a TRIGGER for DELETE and check if the row being deleted shouldn't be allowed to. In such case I'd raise an error.

For more information, see 13.1.11 CREATE TRIGGER Syntax[^]
