Rose::HTML::Form::Field::PhoneNumber::US - Text field that accepts only input that contains exactly 10 digits, and coerces valid input into US phone numbers in the form: 123-456-7890
$field = Rose::HTML::Form::Field::PhoneNumber::US->new( label => 'Phone', name => 'phone', size => 20); $field->input_value('555-5555'); # "Phone number must be 10 digits, including area code" $field->validate or warn $field->error; $field->input_value('(123) 456-7890'); print $field->internal_value; # "123-456-7890" print $field->html; ...
Rose::HTML::Form::Field::PhoneNumber::US is a subclass of Rose::HTML::Form::Field::Text that only allows values that contain exactly 10 digits, which it coerces into the form "123-456-7890". It overrides the validate() and inflate_value(), and deflate_value() methods of its parent class.
This is a good example of a custom field class that constrains the kinds of inputs that it accepts and coerces all valid input and output to a particular format. See Rose::HTML::Form::Field::Time for another example, and a list of more complex examples.
