PHP not receiving data from HTML5 form - php

Question

I am recently getting into php and am running it locally on Xampp. I have created the following simple form followed by a few lines of php. It seems that no data is being passed through from the html form to the php page.
<form method="post" action="emailform.php" enctype="text/plain" class="form-horizontal">
<div class="row input">
<div class="col-md-1"></div>
<div class="col-md-10">
<div class="form-group">
<input type="text" name="subject" id="subject" class="form-control" placeholder="subject">
</div>
</div>
</div>
<div class="row input">
<div class="col-md-1"></div>
<div class="col-md-4">
<div class="form-group">
<input type="text" name="name" id="name" class="form-control" placeholder="full name">
</div>
<div class="form-group">
<input type="email" name="subject" id="email" class="form-control" placeholder="email">
</div>
</div>
<div class="col-md-1"></div>
<div class="col-md-5 textarea">
<textarea class="form-control" name="message" id="message" rows="4" placeholder="message"></textarea>
</div>
</div>
<br>
<div class="row">
<div class="col-md-1"></div>
<div class="col-md-10">
<button type="submit" class="btn" id="submit">Send</button>
</div>
</div>
</form>
This is the simple php code I am using to test:
<?php
$subject = 'No subject was set';
if (isset($_POST['subject'])) {
$subject = ($_POST['subject']);
}
echo "This is the subject:$subject";
?>
I appreciate any help as I have been struggling with this simple code for the past week now.

Answer 1

Two subject names!
<input type="email" name="subject" id="email" class="form-control" placeholder="email">
^
and
<input type="text" name="subject" id="subject" class="form-control" placeholder="subject">
^
Also remove enctype="text/plain" from the form
It's because PHP doesn't handle it
