Smarty Login Problem

    Hallo Community,
    Ich hab ein Problem das ich selber nicht beheben kann.


    Hier sind die Fehler:


    Browser Auszug


    PHP
    real_escape_string($_POST['username']); $Password = $db->real_escape_string($_POST['password']); $CheckAcc = $db->query("SELECT id FROM users WHERE username = '$Username' AND password = '$Password' LIMIT 1"); if($db->num_rows($CheckAcc)) { $_SESSION['username'] = $Username; header("Location: index.php"); } else { echo 'Die angegebenen Benutzerdaten, scheinen nicht korrekt zu sein!'; } } ?>



    NetBeans Editor Auszug

    PHP
    <?phpif(isset($_SESSION['username'])) { header("Location: index.php?page=home"); }session_start();if(isset($_POST['submit'])){    $Username = $db->real_escape_string($_POST['username']);    $Password = $db->real_escape_string($_POST['password']);    $CheckAcc = $db->query("SELECT id FROM users WHERE username = '$Username' AND password = '$Password' LIMIT 1");    if($db->num_rows($CheckAcc))    {    $_SESSION['username'] = $Username;    header("Location: index.php");    } else {        echo 'Die angegebenen Benutzerdaten, scheinen nicht korrekt zu sein!';    }}?><html lang="en">  <head>    <meta charset="utf-8">    <meta http-equiv="X-UA-Compatible" content="IE=edge">    <meta name="viewport" content="width=device-width, initial-scale=1">    <meta name="description" content="">    <meta name="author" content="">    <title> {$title_Firm} - Login</title>    <!-- Bootstrap core CSS -->    <link href="{$system_style}css/bootstrap.min.css" rel="stylesheet">    <!-- Custom styles for this template -->    <link href="{$system_style}css/signin.css" rel="stylesheet">    <!-- Just for debugging purposes.
