Question

could someone please tell me how can i determine what was the user’s selection given a drop-down menu in the following piece of code ? what am i doing wrong ?

#!/usr/bin/perl -wT

use     strict ;
use     warnings ;
use     CGI ;
use     CGI::Carp qw(warningsToBrowser fatalsToBrowser) ;


my      $cgi = new CGI ;
print   $cgi->header(-type=>"text/html", -charset=>"utf-8") ;
print   $cgi->start_html(-title=>"Data Analysis | hellas online") ;

my %labels = (  "yes"   =>      "For Sure!",
                "no"    =>      "Not for me.",
                "maybe" =>      "Maybe So."     ) ;    
print $cgi->popup_menu( -name           => "your_answer",
                        -values         => ["yes", "no", "maybe"],
                        -default        => "yes",
                        -labels         => \%labels     ) ;
my @selected = $cgi->param("your_answer") ;
foreach my $i (@selected)
{
        print $cgi->$i."\n" ;
}
print   $cgi->end_html ;

the … print $cgi->$i.”\n” ; … statement does not display anything ?!

thank you.

You never create a form, so the value of the popup_menu can never be submitted. You need to put your form controls inside a form.

$cgi->param will have data to fetch only after the form data has been submitted (you’ll need a submit button too) back to the server from the browser.
