cookie problem :/

chuckury

Using this code:

<?
$settings[cookiedomain] = ".htmlfunction.beigetower.org/";
$settings[cookiepath] = "/";
include("connect.php");
$user = $_POST['username'];
$pass = $_POST['password'];
$password = md5($pass);
$mysqli = mysql_query("SELECT * FROM `dtusers` WHERE `user` = '$user' AND `password` = '$password'");
$mysqli_n_r = mysql_num_rows($mysqli);
if ($mysqli_n_r == "0") {
	print "Sorry that is an invalid username or password, please try again!";
} else if (isset($_COOKIE["id"])) {
	print "Youre already logged on!";
} else {
	$mdname = md5($user);
	setcookie("id", $mdname, time() * 3600 * 10);
	$_COOKIE["id"];
	print "You have succesfully logged on!";
}
?>

I get this error (Which I really cant seem to solve :/ ):

Warning: Cannot modify header information - headers already sent by (output started at /var/bt/home/web/dennmat/htmlfunction.beigetower.org/html/index.php:13) in /var/bt/home/web/dennmat/htmlfunction.beigetower.org/html/login.php on line 16

please help!

You're trying to use header() after you've already echo'ed something. Just make sure that header('..') is called in advance of anything being echo'd.

Alternatively, look into output buffering, which will manage this for you:

Thanks but...
I don't get anymore errors.
But it doesnt make the cookie :/ :?
Please help again 😉 lol
Here are the changes:

<?
...
} else {
	$mdname = md5($user);
	ob_start();
	setcookie("id", $mdname, time() * 3600 * 10);
	$_COOKIE["id"];
	ob_end_clean();
	print "You have succesfully logged on!";
}
?>

$_COOKIE shows the value of the cookie at the time the user requested the page.

Before the the cookie gets made, $COOKIE is null. You have set the cookie in your code, but $COOKIE retains it value (NULL).

The next time your user requests a page, $_COOKIE will have the value you set.

$_COOKIE doesn't update on the fly, only at the time the page request hits the server.

ok, but it still doesnt set the cookie :/ 😕
