Checking for cookies

[keith73]

OK, I know there are a lot of cookie questions on the forum here, but I can't find anything about my particular issue.

On the homepage I want to check to see if the session cookie is already set. If there is no cookie, it checks for a session ID. If it exists, ini_set is used to disable session cookies.
When a user logs in, they can choose to set a cookie to not have one set. In the login script, ini_set is used to set cookies to TRUE and a session is started.
problem, the session is being created, but the cookie is never set.

login script

if($_POST['use_cookie'] == 'yes'){
				ini_set('session.use_cookies',TRUE);
				$redirect = "home.php";
				session_start();
			} else {
				ini_set('session.use_cookies',FALSE);
				session_start();
				$redirect = "home.php?" . SESSION_NAME . "=" . session_id();
			}

Checking for cookie in homepage

//SESSION_NAME is a constant defined in an include file.
session_name(SESSION_NAME);
if(isset($_COOKIE[SESSION_NAME])){
	ini_set('session.use_cookies',TRUE);
	if(isset($_SESSION['valid_user'])){ session_start(); }
} else {
	if(isset($_SESSION['valid_user'])){
		ini_set('session.use_cookies',FALSE);
		session_start();
	}
}

thanks,

I don't believe you're ever using set_cookie() to actually set the cookie into the users cache; this is probably the problem.

But with sessions, if you have use_cookies turned on, the session_start() will set the cookie.
