// setup a function to display our login form
function displayForm($user='', $pass='')
{
    echo '<form name="form" method="post" action="' . $_SERVER['PHP_SELF'] .'">
  <label for="userlog">Username:</label><br />
    <input type="text" name="userlog" value="' . $user .'"><br />
  <label for="passlog">Password:</label><br />
    <input type="password" name="passlog" value="' . $pass .'"><br />
  <input type="submit" name="Submit" value="Login">
</form>';
}

//check that the user has submitted the login form
if(isset($_POST['Submit']))
{
    $username = "ink";
    $password = "pass";
    $realdate  = date("d.m.Y");
    $username2 = $_POST['userlog'];
    $password2 = $_POST['passlog'];

    // if the form has been submitted we'll now check the username and password
    if($username2 != $username and $password2 != $password)
    {
        // if the chekc didnt pass we'll display the following message
        echo 'Invlid Username or Password, try again';

        // and show our login form.
        displayForm($username2, $password2);
