Hello, Monks. This is what I'm using to un-webby-fy data from a web form: 
if ($ENV{'REQUEST_METHOD'} eq 'POST') {

    read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});

    @pairs = split(/&/, $buffer);

    foreach $pair (@pairs) {
       ($name, $value) = split(/=/, $pair);
       $value =~ tr/+/ /;
       $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;

    $FORM{$name} = $value;
    }

However, I'm having trouble when the user doesn't fill out all the fields. Then in the email to the administrator: 
 open (MESSAGE,"| /usr/lib/sendmail -t");

    print MESSAGE "To: $FORM{submitaddress}\n";
    print MESSAGE "From: $FORM{name}\n";
    print MESSAGE "Reply-To: $FORM{email}\n";

    print MESSAGE "Subject: Faculty Bibliography Submission\n\n";
    print MESSAGE "The following information was submitted from $FORM{
+name} at $FORM{email}:\n\n";
    print MESSAGE "Full Name: $FORM{name}";
    print MESSAGE "\n";
    print MESSAGE "Publication Name: $FORM{pubname}";
    print MESSAGE "\n";
    print MESSAGE "Other Authors: $FORM{otherauthors}";
    print MESSAGE "\n";
    print MESSAGE "Other Editors: $FORM{othereditors}";
    print MESSAGE "\n";
    print MESSAGE "Main Publication Title: $FORM{pubtitle}";
    print MESSAGE "\n";
    .
    .
    .
    .
    close (MESSAGE);

It does not put in the new lines if the user did not fill in a particular field. A new line is only created if there was something entered. My guess is that I need to check for the null (undef??) fields when I un-webby-fy and put a new line "\n" in it instead of leaving it blank. However, my limited perl knowledge keeps me from doing so. Thank you thank you thank you for your help/advice. It would be great if you could e-mail any replies to me as well at elizabeth.dahm@hope.edu
