I used it and it did not return any values @files = $q->param("field"); There is no values in @files. I feel very frustrated.	[reply]

bebewinla This is a down and dirty example. You should taint the data in production. Here is my example. HTML file `<html lang="cs"> <head> </head> <body> <form action="new6.pl"> <input type="checkbox" name="field" value="Red"> Red<br> <input type="checkbox" name="field" value="Blue"> Blue<br> <input type="checkbox" name="field" value="Green"> Green<br> <input type="checkbox" name="field" value="Yellow"> Yellow<br> <input type="submit"> </form> </body> </html>` [download] Perl Code `#!/usr/bin/perl use strict; use CGI qw/:standard :html4/; use CGI::Carp qw ( fatalsToBrowser ); my $query = new CGI; print $query->header(); &logit($0." has started" ); &logit("======================="); &logit($0." ".query_string()); my @values = $query->param('field'); my $ColorCount=@values; print "Colors Selected: ".$ColorCount."<br>"; foreach my $item (@values) { print "Colors: ".$item."<br>"; } exit;` [download] Output `Colors Selected: 4 Colors: Red Colors: Blue Colors: Green Colors: Yellow` [download] I hope this helps	[reply] [d/l] [select]

Hi rpnoble419, Thanks for you sample program. But I still having trouble of getting the values "field". I used TMPL_LOOP NAME to display a list of filenames & checkboxes next to it. This is all done with template & print $template->output. I defined the checkbox inside a form, also a "submit" button. ....... `<form method="post" action="index.cgi"> <td><input type="checkbox" name="field" <TMPL_VAR NAME="check"> value +="<TMPL_VAR NAME = "fn">"></td> </form>` [download] when "submit" is click, my main script index.cgi would check check for the command then call a subroutine "download" `sub download { my @anything = $q->param(); my $anything_num = @anything; my @anyfetch = $q->param("field"); my $anyfetch_num = @anyfetch; print "anything_num = $anything_num"; print "anyfetch_num = $anyfetch_num"; }` [download] both of print give me Zero values, it does not seem like the subroutine is able to fetch the input field from my table html page. I am not sure why. I have the concept, but somehow when applying to coding, it's different story.	[reply] [d/l] [select]
