Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks!

I have a fileupload form submitting a file to this Perl script that I need to FTP once I have the file.
I am getting and error, "No such file or directory".
I am not passing the value correct from the fileupload into the FTP properly, I think.
Any suggestion on how to get this right?
The code sample:
#!/usr/bin/perl

use strict ;
use warnings ;

use CGI ;
use Net::FTP;

my $cgi = CGI->new();

my $file = $cgi->param( 'upload' ) || '';

do_ftp($file);

sub do_ftp {
    
 my $filename = @_;
 return unless $filename ;

 $cgi->upload( 'upload' );
 my $tmp = $cgi->tmpFileName( $filename ) ;
 rename( $tmp, $filename ) ;
 chmod 0664, $filename ;

 my $host = 'xxx';
 my $user = 'user';
 my $pass  = 'pass';
 my $ftpdir = '/';
 
 my $ftp = Net::FTP->new($host, Debug => 0)
    or die "Could not connect to '$host': $@";
 $ftp->login($user, $pass) 
    or die sprintf "Could not login: %s", $ftp->message;
 $ftp->cwd($ftp_dir) 
    or die sprintf "Could not login: %s", $ftp->message;
 
 # FTP file.
 $ftp->put($filename) or die "Cannot put file ", $ftp->message;
 
 $ftp->quit;

}

    Hello Anonymous Monk,

    Try something like this:

    #!/usr/bin/perl
use CGI;
use strict;
use warnings;
use Net::FTP;
use feature 'say';

my $cgi = CGI->new();
my $file = $cgi->param( 'upload' ) || 'test.pl';

say do_ftp($file);

sub do_ftp {
    my ($filename) = @_;
    return unless $filename ;
}

__END__

$ perl ftp.pl
test.pl

    We do not have the full code but I assume my $file = $cgi->param( 'upload' ) || ''; that you are passing an empty string here right? I have alter the code in two points. Observe the () in the subroutine also.

    I would recommend to use module Net::SFTP::Foreign. Similar question with samples of working code(s) Generate temporary file and FTP upload.

    Hope this helps, BR.

      I was missing the "()" in the sub, thanks for pointing that out!

      Is there a bug in Net::FTP?
      I am checking if the file exists using this command:
      my @check = $ftp->ls("$filename"); I am getting an error:
      Can't use an undefined value as a symbol reference at /Net/FTP/datacon
+n.pm line 54.

    I don't see where you are extracting the base filename out of the fully-qualified filename likely being sent by the form. I seem to recall that's an important step.

    /usr/foo/bar/file.txt would need to become file.txt for example.

      Well, any SANE browser just sends the base filename and extension of the local file. MSIE, on the other hand, DOES send a fully qualified name, for no reason. So it looks like code never tested with a broken browser.

        firefox also sends the full filename
