Re^2: Is $formdata present?

Correct. CGi.pm will work for both POST and GET. For existence u couldd use something like..

use CGI qw(:standard);
my %formdata = ();
map {
    $formdata{$_} = param($_);
} param;
if(exists $formdata{'parametername'})
    {do something;}

While using CGI.pm is a good thing, you still made it more complicated than it should be, at least if you ask me ... `use strict; use CGI; my $q = new CGI; my $form = $q->Vars(); if(exists $form->{parameter_name}){ #do whatever }` [download] Of course, you can also use Data::FormValidator. It's suggested if you need more complicated form validation.	[reply] [d/l]

And multipart-formdata encoding also, which you simply ignored.	[reply]

So what's the difference functionally between Defined and Exists? I thought Exists was used for subroutines and hashes? (clearly wrong)..	[reply]

Sorry.. I'm new. Will soon register myself and format my code. But my answer should work for you. Happy Coding	[reply]
