PHPMailer body message empty error - phpmailer

Question

using tutorials I pasted and filled the following PHPMailer php file and made the following html form. However after send the error appears "Message could not be sent.Mailer Error: Message body empty". Please help.
<?php
require 'phpmailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
//$mail->SMTPDebug = 3;
$mail->isSMTP();
$mail->Host = 'smtp.gmail.com';
$mail->SMTPAuth = true;
$mail->Username = 'xxx#gmail.com';
$mail->Password = 'xxx';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
$mail->setFrom('from#example.com', 'Mailer');
$mail->addAddress('xxx#gmail.com', 'Joe User');
$mail->addReplyTo('info#example.com', 'Information');
$mail->addAttachment('/var/tmp/file.tar.gz');
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');
$mail->isHTML(true);
$mail->Subject = 'Here is the subject';
$mail->From = $email;
$mail->FromName = $name;
$mail->Body = $message;
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
?>
and here is the form
<form name="contactform" method="post" action="email.php">
<div class="input-text-container clear">
<input type="text" name="name" id="name" placeholder="Your Name"
class="input-text input-text-left">
<input type="text" name="email" id="email" placeholder="Your E-mail"
class="input-text input-text-right">
</div>
<textarea type="text" name="message" id="message" placeholder="Your
Message" class="textarea"></textarea>
<button type="submit" value="submit Form" class="submit">SUBMIT</button>
</form>

Your script seems to rely on request parameters being available as global variables. But this is a very uncommon (and insecure) practice.
Use $_POST['message'] instead $message and the message body should contain data from the form. Do the same for the other parameters.
