NAME

HTML::FormHandler::Field::Display - display only field

VERSION

version 0.40016

SYNOPSIS

This class can be used for fields that are display only. It will render the value returned by a form's 'html_<field_name>' method, or the field's 'html' attribute.

  has_field 'explanation' => ( type => 'Display',
     html => '<p>This is an explanation...</p>' );

or in a form:

  has_field 'explanation' => ( type => 'Display' );
  sub html_explanation {
     my ( $self, $field ) = @_;
     if( $self->something ) {
        return '<p>This type of explanation...</p>';
     }
     else {
        return '<p>Another type of explanation...</p>';
     }
  }
  #----
  has_field 'username' => ( type => 'Display' );
  sub html_username {
      my ( $self, $field ) = @_;
      return '<div><b>User:&nbsp;</b>' . $field->value . '</div>';
  }

or set the name of the rendering method:

   has_field 'explanation' => ( type => 'Display', set_html => 'my_explanation' );
   sub my_explanation {
     ....
   }

You can also supply an 'html' method with a trait or a custom field. See examples in t/field_traits.t and t/xt/display.t of the distribution.
