You are trying to call a function login, which doesn't excists? — Naruto, Mar 10 '14 at 10:07
you can not do like this... either use AJAX or validate after submit... — user1844933, Mar 10 '14 at 10:08

Why don't you just use

    <?php
     function login() {
    //function body
}
     if($_POST) {
       login();
    }
    ?>

And your html;

<form action="" method="POST">
    UserName <input type="text" name="user"><br>

    PassWord <input type="password" name="pwd"><br>

    <input type="submit" name="login" value="LogIn">
</form>
