Contact.php cropping away Name - php

Question

I got a email.php from a website. How do you add an extra field to it, like phone number?
The original one I downloaded works fine.
Email comes as>>
From: Nuski
E-mail: my#email.com
Subject: Test
Message: Test mail
But when I add $field_phone = $_POST['cf_phone']; and $body_message = "Phone: ".$field_phone."\n";
The email comes without the Name of the sender. Like>>
Phone: 5559
E-mail: flex#f.com
Subject: reCaptcha test
Message: Email Test
Here is my HTML form
<form action="email.php" method="post">
<div class="col-sm-6">
<div class="form-group">
<input class="form-control" name="cf_name" type="text" id="name" placeholder="Your Name" required>
</div>
<div class="form-group">
<input class="form-control" name="cf_phone" type="text" id="phone" placeholder="Phone" >
</div>
<div class="form-group">
<input class="form-control" name="cf_email" type="email" id="email" placeholder="Your Email" required>
</div>
<div class="form-group">
<input class="form-control" name="cf_subject" type="text" id="subject" placeholder="Subject" required>
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<textarea class="form-control btn-block" name="cf_message" id="comments" placeholder="Please include your address and item code for delivery" required></textarea><br>
</div>
<div class="form-group">
<input type="submit" class="btn btn-block" id="submit" value="Send Message">
</div>
</div>
<div class="col-sm-12">
<p class="contact-success">Your Message has been Successfully Sent!</p>
<p class="contact-error">Error! Something went wrong!</p>
</div>
</form>
Here is my email.php
<?php
$field_name = $_POST['cf_name'];
$field_phone = $_POST['cf_phone']; //added by me
$field_email = $_POST['cf_email'];
$field_subject = $_POST['cf_subject'];
$field_message = $_POST['cf_message'];
$mail_to = 'ask#aki.co';
$subject = 'Message from AkiYTeeS - '.$field_subject;
$body_message = "From: ".$field_name."\n";
$body_message = "Phone: ".$field_phone."\n"; //added by me
$body_message .= "E-mail: ".$field_email."\n";
$body_message .= "Subject: ".$field_subject."\n";
$body_message .= "Message: ".$field_message;
$headers = 'From: '.$field_email."\r\n";
$headers .= 'Reply-To: '.$field_email."\r\n";
$mail_status = mail($mail_to, $subject, $body_message, $headers);
if ($mail_status) { ?>
<script language="javascript" type="text/javascript">
alert('Thank you for the message. We will contact you shortly.');
window.location = 'index.html';
</script>
<?php
}
else { ?>
<script language="javascript" type="text/javascript">
alert('Message failed. Please, send an email to ');
window.location = 'index.html';
</script>
<?php
}
?>

Answer 1

Replace:
$body_message = "Phone: ".$field_phone."\n"; //added by me
With:
$body_message .= "Phone: ".$field_phone."\n"; //added by me // You forgot a "." here
Also note that it's better to use \r\n unstead of just \r or \n as windows mac and linux each need a different of the 2 so by adding both it should always work

Answer 2

$body_message = "Phone: ".$field_phone."\n";
You have forgotten the concatenation operator in the above line.
use "." (dot)
$body_message .= "Phone: ".$field_phone."\n";
