multiple forms for the same php file.

[Anon]

hello

I\'m trying to have some sort of plan which include 4 steps. In each of those steps values are being assigned to variables. By clicking next people go through the steps. My problem is that i don\'t know which variables are gonna be know on the form action sheet. All assigned variables or just the ones on the last step.

can somebody give me a hint

THANX

Roel

After a POST only the variables that were defined in the post will be defined in the script. You can work around this in at least two ways. The first is creating the formas dynamically, and printing hidden inputs which contain the data you wnat to pass on to the next step, and the other is a bit more complicated but far more elegant: sessions. Look up the session functions at http://www.php.net/manual/en/ref.session.php

Of course a third option to maintain "state" is to use cookies.

It might be interesting to discuss the merits of one technique vs another. I'm not big on session variables.

1) Global variables (session or not) are tempting to use, but cause other complications (side-effects, etc, another discussion altogether)

2) Sessions time out and all your variables go away

3) Its hard to keep track of what's going on when the user hits the back and forward buttons
