Re: Reading Checkboxes

HMTL tip coming up:
All the checkboxes in the form must have different names. If they have the same name you will only get one value = 'on', even if all boxes are checked.

Update:
I stand corrected. The broken solution presented by Fastolfe is what I have had to use at work. I will have to try ColtsFoots solution next time around.

This does not seem to be the case, the following code `#!/usr/bin/perl -w use strict; use CGI; my $cgi = new CGI; print $cgi->header(); print $cgi->start_html(); my $submit = $cgi->param('submit'); if ($submit) { my @on = $cgi->param('desig'); foreach my $item (@on) { print qq($item<BR>); } exit; } print $cgi->startform(-method=>'post'); print $cgi->checkbox_group(-name=>'desig', -values=>['a', 'b', 'c', 'd', 'e', 'f', 'g']); print $cgi->submit(-name=>'submit', -value=>'Submit'); print $cgi->endform(); print $cgi->end_html();` [download] yields `a c e g` [download] when every other box is checked	[reply] [d/l] [select]

Only if you're using a broken/proprietary CGI parameter parsing routine that does something like this: `foreach my $pair (split /&/, $ENV{QUERY_STRING}) { my ($key, $value) = split(/=/, $pair); $parameters{$key} = $value; }` [download] The correct solution is to defer processing like this to CGI.pm, which will correctly handle multiple checkboxes with the same name.
