#!/usr/bin/perl # # MAILER.CGI # by Matt Kruse (mkruse@saunix.sau.edu) # 7/28/95 # # Mailer.cgi is a script that I always hear requests for. All it does # is takes the entries from a FORM and e-mails them to anyone you # specify in the form in a nice, readable format. # # USAGE # You use this script my putting special fields into your HTML form. # They are as follows: # # # Who to send the results to. Multiple recipients will work fine. # # What the subject should be on the mail message send to recipients # # Who should be listed in the "Reply-To" field of the mail message. # # Inputs do not need to be hidden, but you'll probably want them # that way. # The default response to give the user is at the very end. Anything # after __END__ will be put up as feedback. Edit as you wish. If you # would like the responses to be sent in a specific format, you'll have # to do that on your own. # # THINGS FOR YOU TO CHANGE # ======================== # The sendmail variable tells the script how to find the mailer on your # system. This should be the right path, but change it if you are not # using the standard setup. It uses the -t option to specify the # recipients in the content of the message with To: and Cc: $SENDMAIL="/usr/lib/sendmail -t"; # The CHECK_EMPTIES variable decides whether an error should be returned # if a field is left blank. If it is set to 1, an error message will # be displayed. If it is set to 0, blank fields are acceptable. $CHECK_EMPTIES=0; # ========================= # END OF USER CONFIGURATION print "Content-type: text/html\n\n"; sub ReadParse { # slightly modified from the usual readparse local (*in) = @_ if @_; local ($i, $loc, $key, $val); if ($ENV{'REQUEST_METHOD'} eq "GET") { $in = $ENV{'QUERY_STRING'};} elsif ($ENV{'REQUEST_METHOD'} eq "POST") {read(STDIN,$in,$ENV{'CONTENT_LENGTH'});} @in = split(/&/,$in); foreach $i (0 .. $#in) { $in[$i] =~ s/\+/ /g; ($key, $val) = split(/=/,$in[$i],2); $FOUND=0; foreach (@FIELDS) { $FOUND=1 if ($key eq $_); } if (($key ne 'TO')&&($key ne 'SUBJECT')&&($key ne 'REPLY-TO')&&($FOUND==0)) { push(@FIELDS,$key); } $key =~ s/%(..)/pack("c",hex($1))/ge; $val =~ s/%(..)/pack("c",hex($1))/ge; $in{$key} .= "\0" if (defined($in{$key})); $in{$key} .= $val; } return 1; } &ReadParse; foreach (@FIELDS) {&MissingInfo if (($in{$_} eq '')&&($CHECK_EMPTIES==1));} $SUBJECT=$in{'SUBJECT'}; delete $in{'SUBJECT'}; $REPLYTO=$in{'REPLY-TO'}; delete $in{'REPLY-TO'}; # split up the "to" names for multiple recipients $TO=$in{'TO'}; @TO=split('\0',$TO); # Open Sendmail and do our thing open (SENDMAIL,"| $SENDMAIL") || die "Ain't Gonna Happen"; print SENDMAIL "To: @TO[0]\n"; if ($#TO > 0) { foreach (1..$#TO) { print SENDMAIL "Cc: @TO[$_]\n"; } delete $in{'TO'}; } print SENDMAIL "Subject: $SUBJECT\n"; print SENDMAIL "Reply-To: $REPLYTO\n"; # Display each field and responses foreach (@FIELDS) { $in{$_}=~ s/\0/\n\n * /g; print SENDMAIL "---------------------------------------------------\n"; print SENDMAIL "Input Field: $_\n"; print SENDMAIL "Response:\n * $in{$_}\n"; } print SENDMAIL "---------------------------------------------------\n"; close(SENDMAIL); # Read in the response and print it. undef $/; $_=; print; # What to display as the "missing information" error sub MissingInfo { print < Error
