Session Variable Resetting

[donnapep]

Hello all,

I have a php file called process.php that sets a session variable, namely $_SESSION['transtype']. This page also contains a form that is submitted to final.php.

If I echo the value of $_SESSION['transtype'] at the end of the process.php file, it displays the correct value. However, in final.php, it is no longer set.

In final.php I have the following snippet of code. The output of this page is "Not set." Why is the value of 'transtype' being lost between these 2 pages?

<?
session_start();

$itemID = $_POST['item'];
$numItems = $_POST['numItems'];

if (isset($_SESSION['transtype']))
echo $_SESSION['transtype'];
else
echo "Not set.";
?>

Thx.

What does the code look like in your login page? The relevant part, anyway.

Here is the code from process.php where transtype gets set correctly:

<form method='post' action='final.php' name='order' onSubmit='return validateForm();'>
<?
session_start();

$orderID = $_POST['orderID'];
$_SESSION['orderID'] = $orderID;

if (isset($_POST['insert']))
$_SESSION['transtype'] = "insert";
elseif (isset($_POST['update']))
$_SESSION['transtype'] = "update";
elseif (isset($_POST['delete']))
$_SESSION['transtype'] = "delete";

Do you need to see more?

The session_start() function should throw an error, because you have output data to the browser before starting the session. Try putting session_start() at the beginning of the document, before you put any HTML code.

Thanks so much for your help. That took care of it. I never would have figured that out on my own.

Thanks again!
