Rose::HTML::Form::Field::Email - Text field that only accepts valid email addresses.
label => 'Email',
name => 'email',
size => 30,
maxlength => 255);
$email = $field->internal_value;
# Handle invalid email addresses
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.
Other examples of custom fields:
Uses inflate/deflate to coerce input into a fixed format.
Uses inflate/deflate to convert input to a DateTime object.
A compound field whose internal value consists of more than one object.
A simple compound field that coalesces multiple subfields into a single value.
A compound field that uses inflate/deflate convert input from multiple subfields into a DateTime object.
A compound field that includes other compound fields and uses inflate/deflate convert input from multiple subfields into a DateTime object.
