Answer 1

The problem is here:
<form name="contactform" action="mailer.php" method="post" role="form" enctype="text/plain">
You are encoding as "text/plain". Replace with "application/x-www-form-urlencoded" which is the default or don't include enctype and that will be the default.

Answer 2

you can try it in place of $_POST
if ((!is_array($_POST)) || (count($_POST) < 1)) {
$_POST = json_decode(file_get_contents('php://input'), true);
}
