Contact.php发送电子邮件但内部没有短信

Question

I implemented the following contact form on my website (from a template), and I can send and receive an email message successfully, but the message part (the users text) is NOT received in my Inbox. I receive the Name and From Email, but not the content of the message.

screenshot from the website form

Can someone help finding and fixing the issue? It is the php, the jQuery or the html wrong?

HTML:

<form action="contact.php" class="contact_form" id="form" method="post">
                <div class="col-lg-6 col-md-6 col-lg-offset-3 col-md-offset-3">
                    <span class="input input_name">

                        <label class="input__label" for="name">
                        <span class="input__label_content">Name</span>
                        </label>
                    </span>

Replace

$message = filter_var($_POST['message'], FILTER_SANITIZE_STRING);

with

$message = filter_var($_POST['textarea'], FILTER_SANITIZE_STRING);

Edit: Also this line is questionable:

$subject = filter_var($_POST['subject'], FILTER_SANITIZE_STRING);

There are no fields with a name subject.
