[SOLVED] Session variables question

[jay0316]

I'm trying to use sessions for the first time.  I am creating a multi page form.  The form will allow users to enter a quantity of a particular kit.  I have kit numbers being pulled from a database and entered as the "name" of the input fields for the quantities.

 

On the next page I start the session and I'm trying to add those quantities to the session variables.  I have the kit names in a database so I thought I'd be able to just do a while loop and have it loop through and store the values like so:

 

//start the session
session_start();

$sql = "SELECT * FROM kits";
$results = mysql_query($sql) or die(mysql_error());

while ($row = mysql_fetch_array($results)) {
$knum = $row['number'];

//register session variables
session_register('$knum');

//store posted values in the session variables
$_SESSION['$knum'] = $_POST['$knum'];
}
print $_SESSION['KCTB09'];
$test = $_POST['KCTB09'];
print "test = $test";
session_destroy();
?>

 

The $test variable works, but the session does not print anything.  However if I hard code a kit name in Session like $_SESSION['KCTB09'] = $_POST['KCTB09']; , it works.  Is it just not possible to store session values in a while loop using variables or am I doing something wrong?

 

[syed]

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

 

remove single quotes

 

$_SESSION[$knum] = $_POST[$knum];

That worked perfectly.  Thanks!
