NAME

Spark::Form::Field - Superclass for all Form Fields

VERSION

version 0.2103

SYNOPSIS

 package My::Field;
 use Moose;
 require Spark::Form::Field;
 extends 'Spark::Form::Field';
 with 'Spark::Form::Field::Role::Validateable';
 with 'Spark::Form::Field::Role::Printable::XHTML';

 sub _validate {
     my $self = shift;

     #validate existence of data
     if ($self->value) {
         #If we're valid, we should say so
         $self->valid(1);
     } else {
         #error will call $self->valid(0) and also set an error.
         $self->error('no value')
     }

     #And we should return boolean validity
     $self->valid
 }

 sub to_xhtml {
     #Rather poorly construct an XHTML tag
     '<input type="checkbox" value="' . shift-value . '">';
 }

Note that you might want to look into HTML::Tiny. Or better still, SparkX::Form::Field::Plugin::StarML.

There are a bunch of pre-built fields you can actually use in SparkX::Form::BasicFields.

DESCRIPTION

Field superclass. Must subclass this to be considered a field.

ACCESSORS

name => Str

Name of the field in the data source. Will be slurped on demand. Required at validation time, not at construction time.

form => Spark::Form

Reference to the form it is a member of.

value => Any

Value in the field.

valid => Bool

Treat as read-only. Whether the field is valid.

errors => ArrayRef

Treat as read-only. The list of errors generated in validation.

METHODS

human_name

Returns the label if present, else the field name.

validate

Returns true always. Subclass and fill in _validate to do proper validation. See the synopsis.
