      $username = $_GET['username']; 
      $password = $_GET['password']; 
      $current = sha1($_POST['current']); 
      $new = sha1($_POST['new']); 
      $confirm = sha1($_POST['confirm']); 
      $q = "select * from userdata where username='$username' and password='$current'"; 
      $r = mysqli_query($db,$q); 
      if(mysqli_num_rows($r) > 0){ 
       if($new == $confirm){ 
        $r2 = mysqli_query($db,"update userdata set password='$new' where username='$username' and password='$current'"); 
        header('location:../settings.php?msg=success&username='.$username.'');
