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>';
}
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 );
And clear the errors attached to the fields:
$form->clear_errors;
And to get the top error message to display now that the form has no errors:
$form->force_error_message( 1 );
This /should/ work - but I've never tried anything like it before.
