Hi guys
I am making a mysql (most uptodate version), php (v5) web application
I am making a system which allows multiple user types to login so we will have admin, user, affliates, and customers
I can create a table called members and enter all the records in there and have a field which determins what the user type is. The issue is some members i.e customers will have other fields like age, date of birth etc so they will be extra fields for admin, users and affliates
can someone please advice me on how they would do this
