Clearing shopping cart from session (cookie)

[asy1mpo]

I have used the shopping cart thats on the Adobe site (http://www.adobe.com/devnet/dreamweaver/articles/php_cart_5.0.html)

 

It all works fine except now I need to clear the basket once the order has gone through

 

How can this be done?

 

I have used code for another similar site I have done before but it doesnt clear it. I think its using sessions/cookies differently but dont know really

 

The code I used for other site is

 

<?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 (isset($_COOKIE[session_name()])) {
    setcookie(session_name(), '', time()-42000, '/');
}

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

 

Any help would be great

 

Thanks

Here ya go:

 

http://us.php.net/session

 

Take heed to the warnings inside this page.

So I use

 

<?php
session_start();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
unset($_SESSION['count']);
?> 

 

I have just tried and it doesnt clear the cart????

[shamilton]

Well - I am not sure how you are keeping track of your items...

If you have individual items stored into session variables and then a process counting them and then setting.

 

$_SESSION['count'];

 

Then unsetting that doesn't help.

 

How are you going about this?

<?php
session_start();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
foreach ($_SESSION as $key => $val) {
    unset($_SESSION[$key]);
}
unset($_SESSION);
setcookie(session_id(), '', time()-344444*1000, '/', 'yourdomain.com');

?> 

 

Should kill all session data.

If you unset all session variables you will effectivley log the user out as well as lose any other information you were keeping track of.

The cart table is like this:

 

+--------+----------------------------+--------+----+

| cartId | cookieId                  | itemId | qty |

+--------+----------------------------+--------+----+

|      1 | 5eu9khhbu6cpaqp4kibvn839b4 |    49 |  15 | 

|      2 | 5eu9khhbu6cpaqp4kibvn839b4 |    61 |  13 | 

|      3 | 5eu9khhbu6cpaqp4kibvn839b4 |    21 |  1 | 

+--------+----------------------------+--------+----+

Ideally only want to kill the session for the cart and not everything. Its OK for this site but a future site will have some registering and logging on etc

[asy1mpo]

<?php
session_start();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
foreach ($_SESSION as $key => $val) {
    unset($_SESSION[$key]);
}
unset($_SESSION);
setcookie(session_id(), '', time()-344444*1000, '/', 'yourdomain.com');

?> 

 

Should kill all session data.

 

Do I need to change anything???

 

I created a new page called clear.php and ran it and went back to cart and its still get the items in it!?!?!?

[asy1mpo]

If it helps here is the code for the cart session

 

function GetCartId()
{
	// This function will generate an encrypted string and
	// will set it as a cookie using set_cookie. This will
	// also be used as the cookieId field in the cart table

	if(isset($_COOKIE["cartId"]))
	{
		return $_COOKIE["cartId"];
	}
	else
	{
		// There is no cookie set. We will set the cookie
		// and return the value of the users session ID

		session_start();
		setcookie("cartId", session_id(), time() + ((3600 * 24) * 30));
		return session_id();
	}
}

Just use the setcookie function I posted except with cartId as the name and maybe remove the domain and the slash part. See if that works.

Got it working

 

<?php
//kill session
// 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 (isset($_COOKIE[session_name()])) {
    setcookie(session_name(), '', time()-42000, '/');
}

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

//kill cookie
// set the expiration date to one hour ago
setcookie ("cartId", session_id(), time() - 3600);
return session_id(); 
?>

 

Just having problems now with SecPay related stuff, when it goes to the authorised page it doesnt seem to run the kill session code. Anyway, thats another thing.........

 

Thanks for your help guys
