I found node Re: Form validation - server-side (Dancer) and client-side (javascript) and I'm trying to use the mentioned module CGI::Ex::Validate. I'm trying to get it to work and the code below results in a HTML-Form included with Javascript for client-side. Happy with that, except that I can't seem to find out how to add code that gives me a simple set of radio-buttons. Is there anyone who has experience with that and cares to share information on that?

#!/usr/bin/perl

use CGI::Ex::Validate;

my $val_hash = {
    'group order' =>
      [qw(date fname lname email email2 telephone choice comments)],
    date => {
        name => 'Date(s) of Workshop *',    # field is not optional in
+ this case
        required => 1,

        match       => 'm|^\d\d\d\d/\d\d/\d\d$|',
        match_error => 'Please enter date in YYYY/MM/DD format',
        custom_js   => "function (args) {
            var t = new Date();
            var y = t.getYear()+1900;
            var m = t.getMonth() + 1;
            var d = t.getDate();)
            if (m < 10) m = '0'+m;
            if (d < 10) d = '0'+d;
            (args.value > ''+y+'/'+m+'/'+d) ? 1 : 0;
        }",
        custom_js_error => 'The date was not greater than today.',
    },
