Re^2: CGI::Application and subroutines

Thanks BUU (and [Limbic~Region who msg me), but I not quite sure I'm getting it. Let me explain what's going on in my actual script. If there is an error, the error handler sets up a HTML::Template page using the associate attribute, and uses CGI::Application::Plugin::FillInForm to set any check boxes, etc. and then exits the script by outputing the form with the error, along with any messages.

Here's more of the script

if (@errors) { 
   errorhandler (\@errors, "subscribers", $fifvalues);
};

sub errorhandler {

   my @errorlist;
   my $errors     = shift;
   my $tmplpage   = shift;
   my $fifvalues     = shift;
      
   foreach (@$errors) {
      my %one_record = (errormsg => $_);
      push (@errorlist, \%one_record);
   }

   $template = $self->load_tmpl($tmplpage.'.tmpl',
                                    associate => $query,
                                    die_on_bad_params => 0);

   $template->param( errorlist   => \@errorlist);
   
   my $html_output = $self->fill_form( \$template->output, $fifvalues 
+);
   return $html_output; #exits application
}

Can you show me what the code might look like that preserves this return value? Thanks!

Unless you start messing around with `print` (which I wouldn't recommend until you understand CGI::App more), CGI::App will only display what you explictly return from a runmode. So to show the results of another sub that your runmode calls, you need to get it's results into your runmode's `return`:- `# Perhaps like this... return errorhandler(\@errors) . "here2: " . Dumper(@errors); # ...or this... my $errors = errorhandler(\@errors); return $errors . "here2: " . Dumper(@errors);` [download] --k. Update: s/would/wouldn't/;	[reply] [d/l]
