php - Restrict duplication in single input field
532
I have this code below for assigning numbers to some rental carts(vehicle). I want the numbers to be different for every single cart i.e. every carts has its own unique number. Once the cart number is assigned then no other carts are allowed to have that number. The number is unique for every carts. I am not able to do this by myself, any help from your side will be highly appreciated. Thanks in advance.
