Okay, so we are going with cookies. The problem I have is that I don't
know how to make PHP just read a cookie. I understand how to set a
cookie, and it is stored in memory, which then can be used throughout
the form. I even know how to set a time limit on a cookie to make it
stay on the kiosk computer, but again, we don't want to create the
cookie.
The problem is that I don't want to set a cookie. I want to just read
one that I create manually. Obviously, setting a cookie through our
PHP form would only be able to set one value for all four machines,
yet we want to have 4 different values. Is there a way to just read a
cookie without setting it through PHP?
