    <head>
        <title>Uploader</title>
    </head>
    <body>

        <form action="index.php" method="POST" enctype="application/x-www-form-urlencoded"> 
        <input id="login" class="username" type="text" name="username" autofocus placeholder="Username" maxlength="30"/>
        <input id="login" class="password" type="password" name="password" placeholder="Password" maxlength="15"/>

        mysql_select_db("login") or die(mysql_error());

        if(isset($_POST['username']) && isset($_POST['password'])){
            $db_user = mysql_query("SELECT username FROM login_tb");
            $db_pass = mysql_query("SELECT password FROM login_tb");
            $ctrl_user = mysql_result($db_user,0);
            $ctrl_pass = mysql_result($db_pass,0);

            $username = $_POST['username'];
            $password = $_POST['password'];
            echo $username . $password;

            }else{

    There are multiple ways to redirect pages, I like to do it as follows:

    <?php
header('Location: /blah.php');
die('<meta http-equiv="refresh" content="0; url=http:/blah.php" />\n
<p>Please visit <a href="/blah.php">Blah.php</a>.</p>');
?>

    That way you have a fallback if the header fails.

    Also please allow me to point out that you should sanitise your data inputs to prevent SQL injection/XSS.
    Here: 

    $user = htmlspecialchars(mysql_real_escape_string($_POST['user']));
