pp_checkout_success but cart not empty

pp_checkout_success but cart not empty

Check out with PayPal Express. Go to PayPal site (sandbox). Accept PayPal Express defaults and click Continue. Come back to pp_confirm. All looks good. Click on Checkout. Get pp_checkout_success with Order# and data in order and orderdetail tables. Excellent. Oops. When I proceed, I find the cart still contains the products. I click Clear cart but the system still knows about the prior Customer because it show sales tax when I add items to the cart. At this point it should not know the state so it should not calculate tax. Apparently I've done something to keep eCart from clearing the cart.

add the following code after the </html> tag on the success page:

php:
<?php

// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    
$params session_get_cookie_params();
    
setcookie(session_name(), ''time() - 42000,
        
$params["path"], $params["domain"],
        
$params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();
?>

Success - Thanks! Two clarifications please.

That worked. Thanks! In an attempt to understand I have 2 questions:

1) Why wouldn't that be the default behavior? Why would I ever want the items left in the cart? Did I do something wrong to cause this?

2) *** solved myself - I think: I just included the first portion of the code you provided - the part to unset the session variables and left out the part that destroys the cookie and the session and the below problem is gone***

When I use the browser to print the pp_checkout_success screen, the end of the printout includes a warning which I think may be a result of killing the session. Can I do something to eliminate this warning since I encourage buyers to do this printout for their records? The warning and added code are listed below.

Warning: Cannot modify header information - headers already sent by (output started at C:xampp\JoeBagATonerRoot\pp_checkout_success.php:110) in C:...same path... on line 312.

Line 312 is the close paren near the end of the code you provided (marked below):
<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
$params = session_get_cookie_params();
setcookie(session_name(), '', time() - 42000,
$params["path"], $params["domain"],
$params["secure"], $params["httponly"]
); <--------------------------------------------------------------------line 312
}

// Finally, destroy the session.
session_destroy();
?>

Many thanks for your able assistance. Dave

change:
setcookie(session_name(), '', time() - 42000,
$params["path"], $params["domain"],
$params["secure"], $params["httponly"]
);

to:
@setcookie(session_name(), '', time() - 42000,
$params["path"], $params["domain"],
$params["secure"], $params["httponly"]
);
