NAME

Rose::HTML::Form::Field::Email - Text field that only accepts valid email addresses.

SYNOPSIS

     $field =
       Rose::HTML::Form::Field::Email->new(
         label     => 'Email', 
         name      => 'email',
         size      => 30,

DESCRIPTION

Rose::HTML::Form::Field::Email is a subclass of Rose::HTML::Form::Field::Text that uses Email::Valid to allow only valid email addresses as input. It overrides the validate() method of its parent class, returning true if the internal_value() is a valid email address, or setting an error message and returning false otherwise.

This is a good example of a custom field class that simply constrains the kinds of inputs that it accepts, but does not inflate/deflate values or aggregate other fields.
