HTML::FormHandler::TraUserrContributed PerHTML::FormHandler::TraitFor::I18N(3)

NAME
       HTML::FormHandler::TraitFor::I18N - localization

VERSION
       version 0.40067

       language_handle,	_build_language_handle

       Holds a Locale::Maketext	(or other duck_type class with a 'maketext'
       method) language	handle.	The language handle is used to localize	the
       error messages in the field's 'add_error' method. It's also used	in
       various places in rendering to localize labels and button values, etc.

       The builder for this attribute gets the Locale::Maketext	language
       handle from the environment variable $ENV{LANGUAGE_HANDLE}:

	   $ENV{LANGUAGE_HANDLE} = 'en_en';

       ...or creates a default language	handler	using HTML::FormHandler::I18N.
       (Note that earlier versions required an actual object reference in ENV,
       which is	a bad practice and no longer supported.)  You can pass in an
       existing	Locale::MakeText subclass instance or create one in a builder.

       In a form class:

	   sub _build_language_handle {	MyApp::I18N::abc_de->new }

       Passed into new or process:

	   my $lh = MyApp::I18N::abc_de->new;
	   my $form = MyApp::Form->new(	language_handle	=> $lh );

       If you do not set the language_handle, then Locale::Maketext and/or
       I18N::LangTags may guess, with unexpected results.

       You can use non-Locale::Maketext	language handles, such as
       Data::Localize.	There's	an example of building a Data::Localize
       language	handle in t/xt/locale_data_localize.t in the distribution.

       If you don't want a particular error message to go through
       localization, you can use 'push_errors' and 'push_form_errors' instead
       of 'add_error' and 'add_form_errors'.

       Example of getting the language handle from the Catalyst	context	(where
       the Catalyst context is passed in with 'ctx'):

	   has '+language_handle' => ( builder => 'get_language_handle_from_ctx' );
	   sub get_language_handle_from_ctx {
	       my $self	= shift;
	       return MyApp::I18N->get_handle(
		   @{ $self->ctx->languages } );
	   }
