Answer 1

Please replace your code with below code.

<?php
    $email = (isset($_POST["email"]) ? $_POST["email"] : "");
    $token = (isset($_POST["token"]) ? $_POST["token"] : "");
?>

Actually, if you put some action to your form then its kinda easy one, but seems in your code you're trying to pass it at the back of the interfaces. Then Session can handle that one.
