Setting Cookies

helenb

I'm sure there must be a perfectly simple explanation to this, which is staring me in the face, but I presently can't see it and hopefully someone can point me in the right direction 🙂

I am trying to set a cookie based on a form submission. I set the cookie, but my page doesn't recognise that the cookie has been set until I reload the page (even though in my browser, I can see that the cookie has been set). So I tried to do a redirection back to the same page, but then the cookie doesn't set at all.

This is what I have:

if(!isset($_COOKIE['KSPHPUserID']) && isset($_POST['abluserid']) && $_POST['abluserid'] != "null"){
$user = $_POST['abluserid'];
		//echo 'Userid: ' . $user;
		setcookie("KSPHPUserID",$user);
		$_POST['abluserid'] = "null";
		//header("Location: Forum.php?forum=4");
		//exit();
	}
              echo 'cookie is: ' . $_COOKIE['KSPHPUserID'];

If I use

header("Location: Forum.php?forum=4");

then the cookie doesn't set at all. If comment it out, the cookie sets (as I can see it in the browser settings), but at the

echo 'cookie is: ' . $_COOKIE['KSPHPUserID'];

it prints nothing. If I resubmit the page, only then does the cookie value print.

Hi, Welcome to PHPBuilder! 🙂

Can you surround your code with [PHP ] and [/code] so its easier to read, you can edit your post to do that.

I cant see anything wrong there. However, I don't see any code for outputting the cookie to check that it is indeed set.

Of course it doesn't - why should it?

Can you show us how you tried this, and what code you used to check for the cookie? Also, you might try doing a print_r() on the $_COOKIE superglobal for more info on what cookies are set.

This is expected (and described) behaviour. $_COOKIE is populated with cookie data the server received from the browser. The server won't receive any data from the browser until the browser sends it to the server.

I tried something the same way on another server I have, and the cookie set no problem after a redirection (header("Location: ...."). So I'm thinking there is something wrong with the server I'm worked on - does anyone know what it would be?
