destroy cookie session in function urgent help

[jas168]

Hi all

 

please have a look at the following code.. if it will destroy the cookie session, and then retrieve GetCartId() function.

 

$killcart = $_POST['empty'];

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();

 

if ($killcart = "1") {

setcookie("cartId", "", time());

return session_id();

}

 

else setcookie("cartId", session_id(), time() + ((3600 * 24) * 30));

return session_id();

}

}

 

this don't seem to work..

please advice me how i should restructure this?

 

Thank you Advance
