Login page not going to the next page

[divinedesigns1]

hey im having a little problem, getting to the next page after login, how it should work is i log in with a username and password, then go to the admin page but i log in but cant get to the admin page im using a header(); to get to the admin page but blaaah isnt working,

<?phpif(isset($_POST['username'])){ include_once("../php/config.php"); $username = stripslashes($_POST['username']); $username = strip_tags($_POST['username']); $username = mysqli_real_escape_string($con, $username); $password = preg_replace("[^A-Za-z0-9]", "", $_POST['password']); $password = md5($password);  $query = "SELECT * FROM user WHERE username='$username' AND password='$password'"; $result = mysqli_query($con, $query); if($result){ $login_check = mysqli_num_rows($result);   while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)){	$id = $row['id'];	session_register('id');	$_SESSION['id'] = $id;	$username = $row['username'];	session_register('username');	$_SESSION['username'] = $username;	header("location: admin.php?id=' . row['id'] . '");	exit();   } }else{   echo 'There\'s no such username or password';  }}?>

Is PHP displaying any errors? With header(), you can just do this if you want:

header("location: admin.php?id=row['id']");

If you were using single quotes, then the way you had it should be okay. ie

 header('location: admin.php?id=' . row['id'] );

is there any error showing? do you have error enabled for every type of error? possible reasons..make sure you dont have any output before header call. not even a white space.

header("location: admin.php?id=' . row['id'] . '");

it will not evaluate correct url dots will be treated as string character as it is inside double quotes.

header("location: admin.php?id={row['id'] } ");

ini_set('display_error',true); ini_set('error_reporting',E_ALL|E_NOICE);[/CODprepend it top of the script or make changes to the specific directive to your php.ini. (recomended for development enviourment)ht http://php.net/ini_set <=reference
