cookies and session won't delete

rinventive

I have some code to set a cookie, it seems to be working fine, although I can't delete the cookie. Even after the next page runs the code to expire the cookie. Not sure what I'm doing wrong. Any help would be appreciated.

Heres the code to set the cookie:

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();
	}

Here is one of the many ways that I have tried to expire the cookie:

//remove the cookie from the users machine
setcookie("CartID", "session_id()", mktime(12,0,0,1, 1, 1990));
session_start();
$_SESSION = array();
session_destroy();

Thanks

You remove a cookie by setting it to a time that has already happened. Try something like this:

 setcookie("CartID", '0', time()-10);

That sets the cookie to expire ten seconds ago...so in other words it's gone! Hope this helps

Here is the code from my original post:

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

session_start();
$_SESSION = array();
session_destroy();

here is code suggested to fix the problem, no luck yet though:

setcookie("CartID", "0", time()-10);

Even after this code runs and the page redirects the user back to the home page, their information is still returning. I need it to clear all the information and treat the user as if it was the first visit once again.

I am testing in Firefox and IE.

Thanks again

Wait...you're mixing up sessions and cookies. You dont need to set regular cookies if you're using sessions...just set a session variable. $_SESSION['CartId'] = 12345; Then you can refer to that variable while that user is still in that session. Then once you kill the session it will dissapear.

the session_sid remain even if you destroy it by session_destroy(), in other word the value remain. for you to generate a new you must have session_regenerate_id();
