Drupal 7
It adds 3 new widgets to the text field type at the Field UI.
They are:
CPF - Accepts only valid tax number of individuals
CNPJ - Accepts only valid tax number of companies
CPF / CNPJ - Accepts either one as long as it is a valid number
The view format display are done as followed:
CPF - 000.000.000-00
CNPJ - 00.000.000/0000-00
It also adds 3 new field types for the Form API.
They are:
number_cpf, number_cnpj and number_cnpj_cpf
So, developers can easily build form elements of Brazilian Tax Number types. For example:
$form['my_cpf_field'] = array(
'#type' => 'number_cpf',
'#title' => t('CPF'),
);
$form['my_cnpj_field'] = array(
'#type' => 'number_cnpj',
'#title' => t('CNPJ'),
);
$form['my_cnpj_cpf_field'] = array(
'#type' => 'number_cnpj_cpf',
'#title' => t('CNPJ or CPF'),
);
And that's it! You are done.
The field value is saved into the database without the separators ( . - / ). Take a look at br_tax_number_fields_field_formatter_view() function for figuring out how to attach a field display to your entity.
Here is an example on how to display the field value with their separators:
$display = array('type' => 'number_cnpj_cpf');
$items = array(
array('value' => $value)
);
$cpf_cnpj_field_view = br_tax_number_fields_field_formatter_view('', '', '', '', '', $items, $display);
