session question

[seanpaulcail]

I have created a 16 page form and I need a session to keep all the variables in scope until the end, when I send them out in an email.

I do session start on the first page and a session start on the following pages while registering the variable from the previous page (for example):

<?
// start the session
session_start();
header("Cache-control: private"); //IE 6 Fix

// Get the user's input from the form
$LoanPurpose = $_POST['L32'];

// Create a new Session Value 
session_register('L32');

// Register the input with the value
$_SESSION['L32'] = $LoanPurpos

In this way, I register the session and the variables that were defined in the previous page, that would be textbox name "L32".

On my links to other pages within the form, do I have to do the following (for example a link in a list of links would be):

<option value="declarations.php?session=<?php echo $sess_id ?>">Declarations</option>

Do I need to do this for each link? Or can just place a link without the php code attached to it and start a session at the top of the linked page?

Any help is greatly appreciated

no need to place the session id in the link...php will place a session cookie on the client or place it in the url automatically provided the user does not accept cookies...

it is probably best to place the session code at the top of each page, including the session_register...then fill the session var when ready...keeps the session code together and a little simpler to locate...

Btw, you do not need to use session_register($var) if you use $SESSION['var']. Because assigning a value to the superglobal variable $SESSION is just like registering the variable.
