Below is some code I wrote a while back for doing something similar, though not necessarily exactly the same.
Below that is the HTML form, so you can see the <B>enctype</B> entry.
</p><p>
There are some issues with this code, such as the chance of files being overwritten, but this should give you a starting point.
</p><p>
This script also lets the uploader send an email. Of course, this could be abused, so some restrictions on this should probably be put in place.

<B>My post-upload.cgi script:</B>
<CODE>
#!/usr/bin/perl --
use CGI qw( :standard escapeHTML );
use strict;
my $megabyte = 1024 * 1024; # bytes
my $max_mb = 10; # max no. of MB we will allow
$CGI::DISABLE_UPLOADS = 0;
# CGI module variable for en/disabling uploads (non-zero to disable)
$CGI::POST_MAX = $megabyte * $max_mb;
# CGI module variable for maximum upload size (bytes)
my $base_dir = "/var/www/site1/web/";
my $base_dom = "http://www.website.here/";
my $target_dir = "../uploads";
my $directory = $base_dir . $target_dir;
my $sendmail = "/usr/bin/sendmail";
my @sendmail_opts = ( '-oi', '-t' );
$| = 1;
my $query = new CGI;
my @names = $query->param;
my $url = $query->param("URL");
my $fh = $query->upload('upload_file');
my $filename = $query->param('name');
$filename =~ s/[^A-Za-z0-9\.\_]/_/g;
open OUTF, "> $directory$filename" or die;
binmode OUTF;
while ( $bytesread = read $fh, $buffer, 1024 )
{
print OUTF $buffer;
}
close OUTF;
if ( !$file && $query->cgi_error )
{
print $query->header( -status => $query->cgi_error );
exit 0;
}
open MAIL, "| $sendmail @sendmail_opts" or die "Can't fork sendmail: $!\n";
print MAIL
"From: $0\n",
"To: ", $query->param("TO"), "\n",
"Subject: ", ( $query->param("SUBJECT") || "mailed form submission" ),
"\n\n";
for my $param ( @names )
{
printf MAIL "%s: %s\n", $para, $query->param($param);
}
print MAIL
"\n\nThe link to the uploaded file is $base_dom$target_dir$filename . ",
"It was renamed by the upload script, so you will need to rename it.\n";
close MAIL;
print $query->redirect( -URL => $url );
</CODE>
</p>

<B>My sample upload form (body only):</B>
