sending all data from email with require field - php

Question

I'm creating a user require form in my site. For this I put some validation on compulsory fields, and when a user fills in the form and presses submit and validation is correct then I receive a email on my email address.
But now I would like all user information in the email, like name, city, budget etc... so what changes do I need to make in my email.php script?
If some fields are not compulsory and the user doesn't fill them in, can they affect my script?
My script is:
<?php
$to = "test#networkers.in";
$subject = "a new requiremnet come!";
$message = "Hi,\n\nyou get a new require";
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= "Sender-IP: " . $_SERVER["SERVER_ADDR"] . "\r\n";
$headers .= "From: " . stripslashes($name) . " <" . $email . ">" . "\r\n";
$headers .= "Priority: normal" . "\r\n";
$headers .= "X-Mailer: PHP/" . phpversion();
$sent = mail($to, $subject, $message, $headers) ;
if ($sent) {
echo "Your mail was sent successfully";
} else {
echo "We encountered an error sending your mail";
}
?>
and the data I recieve is:
$name = $_POST['fname'].' '.$_POST['lname'];
$email = $_POST['mail'];
$phone = $_POST['ph'];
$country = $_POST['country'];
$pt = $_POST['pt'];
$cwl = $_POST['cwl'];
$dyhyows = $_POST['dyhyows'];
$pb = $_POST['pb'];
$bpd = $_POST['bpd'];
$hdyhau = $_POST['hdyhau'];

You can add fields to the message body by concatenating them like so:
$message = "Hi,\n\nyou get a new require";
$message .= "\n Name: " . $name;
$message .= "\n Email: " . $email;
$message .= "\n Phone: " . $phone;
$message .= "\n Country: " . $country;
$message .= "\n pt: " . $pt;
$message .= "\n cwl: " . $cwl;
$message .= "\n dyhyows: " . $dyhyows;
$message .= "\n pb: " . $pb;
$message .= "\n bpd: " . $bpd;
$message .= "\n hdyhau: " . $hdyhau
Any fields that weren’t filled in by the user will simply be blank.
