Below is a script that uses CGI.pm to generate HTML code. If the query var 'checks' is NOT present, a form of 5 text boxes (each named 'checks') is printed out with submit button. When the user fills out ALL boxes (i did not include any validation code), the form is submitted and those names are used to dynamically create a checkbox group. The -linebreak option in CGI's checkbox_group() method prints the checkboxes vertically, instead of horizontally.

use strict;
use CGI qw(:standard);

print header, start_html, start_form;

if (my @checks = param('checks')) {

   print checkbox_group(
      -name      => 'myName', 
      -values    => \@checks,
      -linebreak => 1
   );
}
else {
   print textfield('checks'), "<br>" for (0..4);
   print submit;
}

print end_form, end_html;

The HTML:Template code to do this looks like this(cut straight from some production code):

<TMPL_LOOP NAME=fields>
<INPUT TYPE=CHECKBOX NAME="field_<TMPL_VAR NAME="id">" <TMPL_VAR NAME=
+"value">>
<TMPL_VAR NAME="text">
<br>
        </TMPL_LOOP>

You must then pass an array of anonymous hashes which look like this: { id => "id number", value => "checkbox value", text => "What the user sees next to the checkbox" }. In your program this would look like(untested code):

push @array, { id => "id number", value => "checkbox value", text => "
+What the user sees" };
