I basically learned Perl by altering existing scripts (yeah, not the best, I know). I need to generate multiple unique checkboxes in an HTML page, then see if any of them have been checked.

The whole little testing script is below. If I check for simple checkedness, ie, "if ($value)", nothing shows as checked. Likewise for "if ($value eq 'on')" (or any string, or number). If I try "if ($value == 'any damn string')" EVERTHING is on.

I suspect the problem is actually how I am getting the form parameters into the $form_data array, which is a piece of apparent magic from the original script I started with and seems to have worked fine for all the other field types in the actual real cgi program.

The script can be run from http://www.toukleyartgallery.com.au/cgi-bin/checktest.htm

#!/usr/bin/perl -w

BEGIN { open (STDERR, ">test.err");}

use CGI qw(:standard);
use CGI::Carp qw/fatalsToBrowser/;

$ENV{"PATH"} = "";

print "Content-type: text/html\n\n";

$query = new CGI;
foreach $sparam ($query->param())
{
    $form_data{$sparam} = $query->param($sparam);
}

&check_test;

sub check_test()
{
    print qq~

    for $i (1 .. 4)
    {
        for $j (1 .. 4)
        {
            if ($form_data{'box$i$j'} == "definitely not on")
            {
                print "<font color='#FF0000'>Box $i$j:  $form_data{'bo
+x$i$j'}</font> ";
            }
            else
            {
                print "Box $i$j: <input type='checkbox' name='box$i$j'

            }
        }
    }
    print "\n<input type='submit' name='Submit' value='Submit'>\n</for
