in reply to File Upload On Windows 8 and Perl

Okay, going back to the script and HTML file as written at http://www.sitepoint.com/uploading-files-cgi-perl/the upload now works on my site.

I have family commitments for tonight for Independence Day, so I will pick this up as opportunity permits. I would recommend you proceed thus:

  1. Take these two files, adjust only what is needed to make it work on your site -- no functionality changes.
  2. Add one feature from your version at a time, testing each as you go.
    • Don't get in a hurry.
    • Add the module but no other code changes -- make sure something isn't getting exported which is killing you.
    • If just adding module causes no behavior changes, only then proceed. Make small changes for feature addition, and keep re-testing. Find out which piece breaks it.

The HTML file:

The Perl script:

#!/usr/bin/perl -wT

use strict;
use CGI;
use CGI::Carp qw ( fatalsToBrowser );
use File::Basename;

$CGI::POST_MAX = 1024 * 5000;
my $safe_filename_characters = "a-zA-Z0-9_.-";
my $upload_dir               = ".";

my $query         = new CGI;
my $filename      = $query->param("photo");
my $email_address = $query->param("email_address");

if ( !$filename ) {
    print $query->header();
    print "There was a problem uploading your photo (try a smaller fil
+e).";
    exit;
}

my ( $name, $path, $extension ) = fileparse( $filename, '..*' );
$filename = $name . $extension;
$filename =~ tr/ /_/;
$filename =~ s/[^$safe_filename_characters]//g;

if ( $filename =~ /^([$safe_filename_characters]+)$/ ) {
    $filename = $1;
}
else {
    die "Filename contains invalid characters";
}

my $upload_filehandle = $query->upload("photo");

open( UPLOADFILE, ">$upload_dir/$filename" ) or die "$!";
binmode UPLOADFILE;

while (<$upload_filehandle>) {
    print UPLOADFILE;
}

close UPLOADFILE;

print $query->header();
print <<END_HTML;

    I FOUND IT!

    right after I add: 

        if ($user_id eq '') {
        my $cookie = CGI->new;
            $user_id = $cookie->cookie('TEC_USER_ID');
            my $crypt = Crypt::Lite->new( debug => 0, encoding => 'hex
+8' );
                my $decrypted = $crypt->decrypt($user_id, $ip_address)
+;
            $user_id = $decrypted;
    }

      FYI: We don't close threads. I'm not sure anything ever truly goes away at PerlMonks.
