Re: How do I get at the parameters in my CGI program?

As contributed by icuc:

use strict;
use CGI;
# .....
my $q = new CGI;
my %params = {};
{
  my @params_names = $q->param;
  for(@params_names) {
    $params{$_} = $q->param($_);
  }
}

or, a shorter way, as contributed by slayven:

use CGI;
my $q = new CGI;
my %in = map { $_ => $q->param($_) } $q->param;

Lincoln Stein no longer recommends the use of the visible CGI object, simply because the number of CGI objects in a typical program is merely one. Instead, pull in the methods you need as subroutines. If parameter access is all that's required, use: `use CGI qw(param); ... my $source = param('source'); my @destination_states = param('dest'); # multi-select` [download] But I typically use `use CGI qw(:all);` [download] since I'm also using the HTML generation shortcuts. -- Randal L.
