How to get POST Form data into an email - php

Question

I am making a form for my customer to fill out when they order a product.
I am trying to make it so when they hit submit it emails the data to my email and it cc's them. The email will have styling in it. I can't figure out how to get it to put the data into the email. I am currently using PHPMailer.
Here is the php file
<?php
$FirstName = $_POST['First_Name'];
$LastName = $_POST['Last_Name'];
$Email = $_POST['Email'];
$Company = $_POST['Company'];
$dochtml = new DOMDocument();
require_once('PHPMailer/PHPMailerAutoload.php');
$mail = new PHPMailer();
$mail->isSMTP();
$mail->SetFrom('No-Reply#LDSVacuum.com');
$mail->Subject = 'Request';
$mail->AddAddress('Chase.Price#LDSVacuum.com');
$mail->AddCC($Email);
$strhtml = '
<div align="center">
<font face="arial" color="#336699" size="6">
Request
</font>
</div>
<div>
<font face="arial" color="#336699" size="5">

</font>
<p>
<label for="fname">
<font face="arial" color="#336699" size="4">

</label>
<br />
<input type="text" name="fname" id="fname" size="50">
</p>
<p>
<label for="lname">
<font face="arial" color="#336699" size="4">

<br />
<input type="text" name="lname" id="lname" size="50">

<p>
<label for="email">
<font face="arial" color="#336699" size="4">

<br />
<input type="text" name="email" id="email" size="50">

<label for="company">

</font>
</label>
<br />
<input type="text" name="company" id="company"size="50">
</p>
</div>
';
$dochtml->loadHTML($strhtml);
$fname = $dochtml->getElementById('fname');
$fname->value=$FirstName;
$lname = $dochtml->getElementById('lname');
$lname->value=$LastName;
$email = $dochtml->getElementById('email');
$email->value=$Email;
$company = $dochtml->getElementById('company');
$company->value=$FirstName;
$mail->Body = $strhtml;
$mail->Send();
if(!$mail->Send()) {
echo 'Unknown Error has Occured. Please try again Later.';
echo 'Mailer error: ' . $mail->ErrorInfo;
}else {
echo 'Thank You, $FirstName . We have emailed your request to Info#LDSVacuum.com . Your email $Email has been cc to the email.';
}
?>
Here is the form

<form method="POST" name="contactform" autocomplete="off" id="nipplerequest" action="http://localhost/emailform.php">

Answer 1

You are:
Creating a string of HTML
Creating a DOM from that string of HTML
Modifying that DOM by setting values
Emailing the original string of HTML and ignoring the DOM you generated
You need to convert the DOM back into HTML ($modified_html = $dochtml->saveHTML()) and send that instead of your original string.
