I suggest you look into HTML::Template, it can simplify perl/cgi/html projects alot.

    try this for fun - it accepts the text box values as anrray #!/usr/bin/perl ## relatively painless iteration over multiple selection boxes use CGI qw(:standard); @sel = param('sel'); @entry = ("first", "second", "third", "fourth", "fifth", "sixth", "sev +enth", "eighth", "ninth", "tenth"); print "Content-Type: text/html\n\n"; if ($sel[0] ne '') { # do database stuff here (each entry in the sel array is the index to + your array of data for the database) ## just for fun show boxes checked foreach $ent (@sel) { print "you checked the $entry[$ent] box<br>\n"; } } print <<EOF <form name=fred action=jd.cgi> <table> <tr> <td> one <input type=checkbox name=sel value=0> </td> <td> two <input type=checkbox name=sel value=1> </td> <td> three <input type=checkbox name=sel value=2> </td> <td> four <input type=checkbox name=sel value=3> </td> <td> five <input type=checkbox name=sel value=4> </td> </tr> <tr> <td> six <input type=checkbox name=sel value=5> </td> <td> seven <input type=checkbox name=sel value=6> </td> <td> eight <input type=checkbox name=sel value=7> </td> <td> nine <input type=checkbox name=sel value=8> </td> <td> ten <input type=checkbox name=sel value=9> </td> </tr> </table> <input type=submit value=showme> </form> EOF Hope this helps John
      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, ;


      (the triplet paradiddle with high-hat)
        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.
