Hi guy's,

I'm having problems adjusting a script to add a level (user rights) function. When i login with a admin or normal user it gives a blank page (not redirecting to home.php). It even does'nt return an echo that user / pass is incorrect. I'm breaking my head over this for day's now. Can you help me out?

Code: [Select]
<?php
session_start();

//Login form (index.php)

include "db_connect.php";
if(!$_POST['submit'])
{
?>

<html>
<head>

<![if !IE]>
<link rel="stylesheet" type="text/css" href="firefox.css" />
<![endif]>
</head>
<body>
<div id="wrapper">
<div id="header">
<?php include('header.php'); ?>
</div>
<div class="divider">

<strong>Login</strong>
<form method="post" action="index.php">

<div class="formElm">
<label for="username">Klantnummer:</label>
<input id="username" type="text" name="username" maxlength="16">
</div>

<div class="formElm">
<label for="password">Wachtwoord:</label>
<input type="password" name="password" maxlength="16">
</div>

<input type="submit" name="submit" value="Login">
</form>

</div>
<div id="footer">
<?php include('footer.php'); ?>
</div>
</div>
</html>

<?php
}
else
{
  $user = protect($_POST['username']);
  $pass = protect($_POST['password']);
  $level = protect($_POST['level']);

if($user && $pass && $level)
{
$pass = md5($pass); //compare the encrypted password
$sql1 ="SELECT id,username FROM `users` WHERE `username`='$user' AND `password`='$pass' AND `level`='1'";
$sql2 ="SELECT id,username FROM `users` WHERE `username`='$user' AND `password`='$pass' AND `level`='9'";
$queryN=mysql_query($sql1) or die(mysql_error());
$queryA=mysql_query($sql2) or die(mysql_error());

if(mysql_num_rows($queryN) == 1)
    {
      $resultN = mysql_fetch_assoc($queryN);
  $_SESSION['id'] = $resultN['id'];
      $_SESSION['username'] = $resultN['username'];
header("location:home.php");
    }
    elseif(mysql_num_rows($queryA) == 1)
    {
      $resultA = mysql_fetch_assoc($queryA);
  $_SESSION['id'] = $resultA['id'];
      $_SESSION['username'] = $resultA['username'];
header("location:home.php");
}

else{
echo "Wrong Username or Password";
}
}
}
?>
and the mysql code:

Code: [Select]
CREATE TABLE `user` (
`id` int(4) unsigned NOT NULL auto_increment,
`username` varchar(32) NOT NULL,
`password` varchar(32) NOT NULL,
`level` int(4) default '1',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=27 DEFAULT CHARSET=latin1;
