Re: Input arrays to CGI

CGI.pm will handle this. All you need to do is request the multi-value parameter as a list:

use strict;
use CGI qw(param);
use Data::Dumper;

my @list = param('list');
print Dumper \@list;

Run this on the command line like so:

./foo.pl 'list=foo&list=bar&list=baz&list=qux'

and you should see the following:

$VAR1 = [
          'foo',
          'bar',
          'baz',
          'qux'
        ];

Note that since CGI.pm version 4.05 (released in 2014) using this approach will cause a warning to be emitted regarding the potentially unsafe nature of it. You can improve the safety (and by doing so avoid the warning) by calling multi-param instead. `#!/usr/bin/env perl use strict; use warnings; use CGI qw(multi_param); use Data::Dumper; my @list = multi_param ('list'); print Dumper \@list;` [download] 🦛	[reply] [d/l]
