form variables and sessions

[Anon]

I keep running into a problem with passing form variables between
scripts using sessions.

I have a bunch of forms which contain four hidden variables,

mitemnum - item number
mdescrip - item description
mprice - item price
mprev - return url

Every time a user submits one of these forms, I add the current variable
to the end of an array. if I've submitted three forms, I have three elements
in each array.

Since this is a cart application I can show the cart with a formatted
printing of array elements.

I started storing my arrays in cookies but needed to use sessions since
some users have cookies turned off. Now I can't figure out how to maintain
state and maintain my arrays as globals throughout the session.

What's the trick?

Thanks.

I'm having exactly the same problem.
As soon as I start using sessions, the values that I pass the script from a form (or as a manually-typed-in url for that matter) seem to disappear.

If I don't use sessions then the script can see the variables perfectly.

There's something that I'm missing.

I'm having the same problem. I made a script ealier that could send the variables just fine, but not anymore.

n1.php:

session_start();

session_register("job_name");
session_register("product");
session_register("parts");

That is how I was taught to do it. The form, which uses the same variables, submits to n2.php. If I do an echo command on n2.php it displays them just fine. n2.php has more variables on it, which go to n3.php. n3.php can display the variables from n2.php but NOT from n1.php which I'm confused about since I thought sessions were persisitent and always stayed during the lifetime of the browser being open unless otherwise noted.

i thought that you had to pass the vars from the previous pages as hidden values to maintain the info ..?

The whole idea behind sessions is to save you from doing that.
