Then I do wonder what it was intended for then, if not for tracking the state of uploads.
Nowhere is it suggested you can get your chicken before upload hook. It says The $data field is optional; it lets you pass configuration information (e.g. a database handle) to your hook callback.

<!-- using GET will make the QUERY_STRING as mentioned in the previous post, but.. that's not how it's supposed to be? --> Who suggested you use get? I said as long as action is /foo/bar.cgi?chicken=ididid Example 

#!/usr/bin/perl  -- 

use strict;
use warnings;

use CGI();

$|=1;
$ENV{QUERY_STRING}="";

{

    my $q = CGI->new("".$ENV{QUERY_STRING});
    $q->param(qw' chicken ididid ');

    print join "\n",
    $q->start_html,
    $q->start_form(
        -method=>'POST',
        -action=>  $q->self_url,
        -enctype=> &CGI::MULTIPART
    ),
    $q->filefield('file'),
    $q->hidden(pregeneratedID => 123456 ),
    $q->end_form,
    $q->end_html;
}
