An example for simple form-filling:

#!/usr/bin/perl

use strict;
use warnings;

use WWW::Mechanize;

my $mech = WWW::Mechanize->new();
my $page = "http://www.heise.de/newsticker/";

$mech->get($page);
$mech->form_number('2');
$mech->field('T' => 'SCO');
my $results = $mech->submit();
print $results->content(), "\n";

#!/usr/bin/perl

use strict;
use warnings;

use WWW::Mechanize;

my $mech = WWW::Mechanize->new();
my $page = "https://www.realquest.com/jsp/rq.jsp?action=switch&page=ma
+in";

$mech->get($page);
$mech->form_number('1');
$mech->field('username' => 'test');
my $results = $mech->submit();
print $results->content(), "\n";

I am getting the error: There is no numbered form 1 at login.pl. How can this be when the URL I am using has atleast one form?

i have also different prolem. when i fill form like here: $mech->field('username' => 'test'); everythig goes ok, but when i fill it with some var: $mech->field('username' => $test); i should tell that var $test is passed as an sub arg. It tells me error: Died at /usr/local/lib/perl5/site_perl/5.8.8/WWW/Mechanize.pm line 1681. Any ideas? best gegards, rafael

This seems straight forward enough to me. First off I would point you to CGI and suggest you read the man pages. In there are suggestions for how to deal with cookies and the like. Secondly talk to your system adminsitrator about file permissions and what user id your web server is running as and make sure your CSV file is working correctly.

As far as reading in the CSV file there are more ways to do that than I can possibly enumerate here. The simplest of which would be:

open FIN,"< myfile.csv" 
    or die "could not open mysfile.csv:$!";
while(my $line=<FIN>){
    chomp $line;
     my @fields=split/[\,]/,$line);
     # do something with it
}
# etc.

Since you are trying to fill out a form with the data I would suggest you look at LWP::UserAgent and friends.

What have you tried and what has failed and in what manner did it fail? You reference a web page, why?

UPDATE: misunderstood the question(s).
