Re: [html-formfu] Suppressing error message output?

[Matthias Dietrich]

Hi,

hm, I see I have forgotten something :).

Hmm, not easy - I'd normally suggest looking at t/examples/ for custom
rendering, but the render_field() and render_label() methods require
TT.

I'd suggest inspecting the field errors to build your error message.
Something like this (as a very rough example):

   my $error_message = '';
   for my $field ( @{ $form->get_fields } ) {
       my @errors = @{ $field->get_errors({ forced => 1 });
       next if !...@errors;
       $error_message .= sprintf '<p>field %s has errors</p><ul>', (
$field->label || $field->name );
       for my $error (@errors) {
           $error_message .= sprintf '<li>%s</li>', $error->message;
       }
       $error_message .= '</ul>';
   }

I already have the collected error messages, although your way seems to be much better and I will adapt that - thanks!

To get it displayed at the top of the form:

   # use _xml() variant as our message contains xhtml tags
   $form->form_error_message_xml( $error_message );

Ok, I will try that. Good point! As I'm really new to FormFu I would have placed the message manually in front of the form :(.

And clear the errors attached to the fields:

   $form->clear_errors;



   $form->force_error_message( 1 );

And to get the top error message to display now that the form has no errors:

Thanks for helping,
  Matthias

To clear the errors was the only way I found to suppress the error message output in front of the labels. But I guess that also suppresses modification of the field classes so that I'm not able to mark the labels red by CSS, right? In my opinion it's a much better user experience to have the occurred errors in front of the form instead letting the user search through the whole form to find the errors. But I also want to have an indicator near the fields saying that this field needs corrections (like a star oder red colored label). Clearing the errors will also prevent indicating the fields.
