one file will be html..

<html>
<head>
<body>
<table border="0" cellspacing="3" cellpadding="3">
        <form id="login-form" method="post" action="login.php">
        <tr><td>Username</td><td><input type="text" name="username"></td></tr>
        <tr><td>Password</td><td><input type="password" name="password"></td></tr>
        <tr><td colspan="2" align="right"><input type="submit" name="submit" value="Login"></td></tr>
        </form></table>
</body>
</head>
</html>

then in this case, login.php will contain the necessary php to handle the form..

php will be something like

 

if ($_SESSION['uid']) {
    echo "You are already logged in, if you wish to log out, please <a href=\"./logout.php\">click here</a>!\n";
} else {

    if (!$_POST['submit']) {
        $user = mss($_POST['username']);
        $pass = $_POST['password'];
        
            if($user && $pass){
                $sql = "SELECT id FROM `users` WHERE `username`='".$user."'";
                $res = mysql_query($sql) or die(mysql_error());
                if(mysql_num_rows($res) > 0){
                    $sql2 = "SELECT id FROM `users` WHERE `username`='".$user."' AND `password`='".md5($pass)."'";
                    $res2 = mysql_query($sql2) or die(mysql_error());
                    if(mysql_num_rows($res2) > 0){
                        $row = mysql_fetch_assoc($res2);
                        $_SESSION['uid'] = $row['id'];
                        
                        echo "You have successfully logged in as " . $user . "<br><br><a href=\"./index.php\">Proceed to the Forum Index</a>\n";
                    }else {
                        echo "Username and password combination are incorrect!\n";
                    }
                }else {
                    echo "The username you supplied does not exist!\n";
                }
            }else {
                echo "You must supply both the username and password field!\n";
            }
    }

}

if($user && $pass){

$sql = "SELECT id FROM `users` WHERE `username`='".$user."'";

$res = mysql_query($sql) or die(mysql_error());

if(mysql_num_rows($res) > 0) {

$sql2 = "SELECT id FROM `users` WHERE `username`='".$user."' AND `password`='".md5($pass)."'";

                    $res2 = mysql_query($sql2) or die(mysql_error());

                    if(mysql_num_rows($res2) > 0){
