setcookie() 不设置 cookie

Question

I have an internal network running XAMPP. I am trying to set a cookie for an item when someone logs in. I use the following code. $Access will be a 1 if user authenticates correctly. When a user enters their username and password it passes to a CheckAuth page with the following code.

$Access = authenticateUser($_POST['Username'],$_POST['Password']);
setcookie("Access", $Access, time()+3600);
header('Location:Newpage.php');

On the NewPage it if I do a $_COOKIE['Access'] it will show me 1 and set everything correctly. If I click a link to another page, say Inventory.php, within the same folder, $_COOKIE['Access'] shows 0 instead of 1.

What could be the issue that the cookie is magically gone? I have checked the IE files for the cookie when it is made and it doesn't show up.

Answer 1

The super global, $_COOKIE , only contains cookies that were given by the browser to the server in the incoming Request.

setcookie() only sets up HTTP headers for the outgoing Response that will instruct the browser to set a cookie.

If you want this cookie to be available in $_COOKIE , you'll need to set it manually at the same time as you call set_cookie() :

setcookie('Access', $Access);
$_COOKIE['Access'] = $Access;

Answer 2

$Access = authenticateUser($_POST['Username],$_POST['Password']);

Missing a quote after $_POST['Username

$Access = authenticateUser($_POST['Username'],$_POST['Password']);
