How to upload file via FTP in CGI script?

Question

Please see the upload script below. It works, but what I want to do, is use the my FTP site for the Upload_dir, instead of the local directory of my website, which is hosted by my service provider.

Please suggest what I should do different to make this work! Thank you in advance

#!/usr/bin/perl
use CGI::Carp qw(fatalsToBrowser);
use CGI;
use File::Basename;
$CGI::POST_MAX = 1024 * 5000;
my $safe_filename_characters = "a-zA-Z0-9_.-";
my $upload_dir = "MyWebsite/upload";
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 file).";
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;
print $query->header();
while ( <$upload_filehandle> )
{
  print UPLOADFILE;
}
close UPLOADFILE;
print $query->header ( ); print qq~

I guess the simplest way is to upload to the local file like you are doing. Once the file is uploaded you should then add sime Net::FTP code to send the file from the webserver to your FTP server. Your service provider will need to allow outgoing FTP for this to work.

use Net::FTP;
...
close UPLOADFILE;
my $ftp = Net::FTP->new( $your_ftp )         || die "$@";
$ftp->login($ftp_user,$ftp_pswd)             || die $ftp->message;
$ftp->cwd($ftp_dir)                          || die $ftp->message;
$ftp->binary();
$ftp->pasv();   # optional. May be required
$ftp->put("$upload_dir/$filename",$filename) || die $ftp->message;
undef $ftp;
...

By the way I usually use an auto generated local filename to ensure two users uploading at the same time with the same name don't cause issues. I usually use something like time().'-'.$$
