NAME

       HTML::FormHandler::Result - form result object

VERSION

       version 0.40013

SYNOPSIS

       This is the Result object that maps to the Form.

	   my $result = $self->form->run( $params );
	   my $result2 = $self->form->run( $other_params );

	   my $value = $result->field('title')->value;
	   my $fif = $result->fif;
	   my $field_fid = $result->field('title')->fif;

   DESCRIPTION
       Although not experimental, the 'results' have not been exercised as much as the other parts of the code. If there is missing functionality
       or things that don't work, please ask or report bugs.

       The original FormHandler 'process' method, when used with persistent forms, leaves behind state data for a particular execution of
       'process'. This is not optimal or clean from an architectural point of view.  The intention with the 'result' object is to separate dynamic
       data from static.  The 'form' object is treated as a kind of result factory, which will spit out results and leave the form in a consistent
       state.

       In the current state of implementation, the result object can be used to render a form:

	  $result->render;

       However there are still open questions about how much of the form/field should be forwarded to the result. At this point, the number of
       forwarded methods is minimal. Mechanisms to make this more customizable are being considered.

       Dynamic select lists are not supported yet. Static select lists (that are the same for every form execution) should work fine, but lists
       that are different depending on some field value will not.

       Most of this object is implemented in HTML::FormHandler::Role::Result, because it is shared with HTML::FormHandler::Field::Result.

NAME

       HTML::FormHandler::Field::Upload - file upload field

VERSION

       version 0.40013

DESCRIPTION

       This field is designed to be used with a blessed object with a 'size' method, such as Catalyst::Request::Upload, or a filehandle.
       Validates that the file is not empty and is within the 'min_size' and 'max_size' limits (limits are in bytes).  A form containing this
       field must have the enctype set.

	   package My::Form::Upload;
	   use HTML::FormHandler::Moose;
	   extends 'HTML::FormHandler';

	   has '+enctype' => ( default => 'multipart/form-data');

	   has_field 'file' => ( type => 'Upload', max_size => '2000000' );
	   has_field 'submit' => ( type => 'Submit', value => 'Upload' );

       In your controller:

	   my $form = My::Form::Upload->new;
	   my @params = ( file => $c->req->upload('file') )
		    if $c->req->method eq 'POST';
	   $form->process( params => { @params } );
	   return unless ( $form->validated );

       You can set the min_size and max_size limits to undef if you don't want them to be validated.
