Hello, I'm writing a web framework and I try to imitate the convenient behaviour of PHP, where script parameters are always present under $_POST, $_GET or $_REQUEST. I'm using CGI::Lite to do this. I created a module called iPLib::iRequest.pm and what i want to do is to put this module in the target script after form submit, so that I don't have to create an CGI::Lite object in every script and retrieve the form parameters with CGI::Lite->parse_form_data().

My (for better explanation simplified) module-code looks like this: 
package iPLib::iRequest;
require Exporter;
our @ISA    = qw(Exporter);
our @EXPORT = qw($_POST);

use warnings;
use strict;
use CGI::Lite;

our $_POST;

 my $cgi = CGI::Lite->new();
    
  $_POST = $cgi->parse_form_data('POST');

1;

This module is included in my target script like this (don't care for the other modules):


use warnings;
use strict;
use CGI::Carp qw(fatalsToBrowser warningsToBrowser);
use CGI::Cookie;

use iPLib::iCFG;
use iPLib::iDoc;
use iPLib::iRequest;

my $doc = iDoc->new( BodyOnLoad => 'iInitJS()');

  $doc->iAddContent("<br>".$_POST->{'TESTNAME'}."<br>");
 
 $doc->iDraw;

This does not work, I'm getting no warning or error messages, but form-parameter TESTNAME is empty or does not change after subsequent calls. When I use CGI::Lite directly, everything works perfect.

I think i have a basic misunderstanding when the module code is executed and the exported variable $_POST is initialized.

Can anyone help me on the way ?
