Errore POST

[tryhere]

<form id="login" action="login/login.php" method="post">
        <input id="username" type="text" placeholder="username">
        <input id="password" type="password" placeholder="password">
        <button type="submit">Login</button>
</form> 

File login.php:

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

Eppure qualunque nome utente io inserisca non stampa nulla...

nel form dovresti inserire il nome del campo.

<form id="login" action="login/login.php" method="post">
<input id="username" type="text" name="username">
<input id="password" type="password" name="password">
<button type="submit">Login</button>
</form>
