Ughh! If you are going to use CGI, then use CGI!!
#!/usr/bin/perl -T use strict; use warnings; use CGI::Pretty qw(:standard); my @entry = ( [qw(one first)], [qw(two second)], [qw(three third)], [qw(four fourth)], [qw(five fifth)], [qw(six sixth)], [qw(seven seventh)], [qw(eight eighth)], [qw(nine ninth)], [qw(ten tenth)], ); print header, start_html('test'); print map "$entry[$_][1] box checked".br, param 'sel' if param 'go'; print start_form('fred'), table( Tr(td[map checkbox('sel',undef,$_,$entry[$_][0]), 0..4]), Tr(td[map checkbox('sel',undef,$_,$entry[$_][0]), 5..9]), ), submit(-name=>'go',-value=>'showme'), end_form, end_html, ;
;)

    More often than not I believe that CGI's html-generating methods are not a good approach.

    Of course I also don't have a single answer that I would suggest in place, there are many ways of generating HTML and they each are appropriate in different places. For more detailed thinking on the factors that I consider, please see Re (tilly) 6: Code Critique.

      You are absolutely correct. I chose to rewrite the original using nothing but CGI.pm to demonstrate that it can be done. I do that from time to time just to keep my CGI.pm skills sharp - while i rarely use CGI.pm in production, i use it all the time here at the Monastery.

      If you look carefully, you will see that checkboxes are each embedded inside their own table cell ... this makes using CGI.pm's checkbox_group() next to impossible. I'll bet a dollar or two that this was the motivation for checkbox(). This is so much easier to handle with HTML::Template, IMHO:
