[Resolved] Variables in sessions - more problems

magic-chef

I am using a session variable to track the status of a user's actions like this.

if ($SESSION['mtype'] == '0' || $SESSION['mtype'] < '0')
{
$SESSION['action']='new';
//echo $SESSION['action']."=Act on credit m=0||<0<br>";
$SESSION['pay']= $POST['paytype'];
$SESSION['amt']=$POST['amount'];
header("Location: login.php");
}

This directs to a login so users can login to the site or register.

Naturally, when I put the echo in which is commented out I did not get to the header location but the echo did indicate the action was 'new'.

I closed the browser to remove cookies and session data and started again. (After commenting out the echo). Upon arriving at the login.php this was echoed from the other script on page load.

old=Action at login.php start

Old is the default.

Why would the var change. there is no code between the header command and the login page.

try using;
$_SESSION['action']="new";

and try unregistering the $_SESSION['action'] before redirection

First, Ineed the session action for decision logic on the next page. Wouldn't I loose that value if I unregistered the session action?

Second, What is the difference between "new" (Double quote) and 'new' (single quote) when assigning values to vars?

Is it possible the header() command alters the $_SESSION['action'].

Here is the output when the echo command in the control statement is NOT commented out:

new=Action on credit m=0||<0

Warning: Cannot add header information - headers already sent by (output started at /var/??????/purchase-credit.php:16) in /var/????/purchase-credit.php on line 19

note that 'new' is the action value here.

Remove the echo and you get this:

old=Action at login.php start

decided to rephrase the issue

When you uncomment the echo statement, definitely you'll get those errors as PHP does not allow any echo statement before the header function.

From the look of things, it's either your if condition is not true, may be that's why you always get $_SESSSION['mtype'] =old; Do the following:

Test if your conditional statement is true.
If your conditional statement is true, then set
$SESSION['action'] = null;

$SESSION['action'] = "new";
On your redirected login.php page do:
//Retreive input variables from HTTP get or post
$userinfo = strtolower($REQUEST_METHOD) == 'get'
? $HTTP_GET_VARS : $HTTP_POST_VARS;

to get the value for your $_SESSION['action'] by doing;

somevariable = $userinfo[$_SESSION['action'];

Try this and let's see what happens.
