forms variables and sessions

[seanpaulcail]

I have an html that extends several pages. I begin with <?php
// start the session
session_start();
header("Cache-control: private"); //IE 6 Fix
?>
on each page

Do I have to register every field on the form on each page? for example:

// Get the user's input from the form
   $name = $_POST['name'];

When I conitnue onto the next page of the form should I post the form info to a php page that processes that info? Then on the next page of the form, when the user continues onto the third page, should I post the form to the same page that the first page of the php form was processed on?

I'm a little confused, any help is greatly appreciated.

Thanks

you can look some examples at

http://www.php.net/manual/en/ref.session.php

and the users-contribution notes have examples too

There are also some examples and explanation in the Newbie's FAQ.
