Php help with form mail

alright i made a survey for my site and I can’t seem to figure out the send email php stuff. I get the email when i click submit but it only shows the “comments” and I dont know how to set up the other sections (listed below). I also included the bottom part of the php code, so how do i recieve the rest of the areas?

Favorite- list/menu
Visit- list/menu
Newsletter- checkbox
and then Navigation (set of radio buttons) which is not shown in the php code.
please help.

// -------------------- END OF CONFIGURABLE SECTION ---------------
$name = $_POST['first_name'] ;
$surname = $_POST['last_name'] ;
$email = $_POST['email'] ;
$comments = $_POST['comments'] ;
$favorite = $_POST['favorite'] ;
$visit = $_POST['visit'] ;
$newsletter = $_POST['newsletter'] ;
$http_referrer = getenv( "HTTP_REFERER" );
if (!isset($_POST['email'])) {
 header( "Location: $formurl" );
 exit ;
}
if (empty($name) || empty($email) || empty($comments)) {
   header( "Location: $errorurl" );
   exit ;
}
if (get_magic_quotes_gpc()) {
 $comments = stripslashes( $comments );
}
$messageproper =
 "This message was sent from:
" .
 "$http_referrer
" .
 "------------------------- COMMENTS -------------------------

 $comments .

mail($mailto, $subject, $messageproper, "From: \"$name\" \"$surname\"<$email>
