CNPJ (Cadastro Nacional de Pessoa Juridica) Field Type for PyroCMS
Download the cnpj field type and place it in addons/shared_addons/field_types or addons/[site_ref]/field_types and make sure that the folder you will copy is named "cnpj" without quotes.
This FieldType will check if the input is 14 numeric long (removing '.', '-' and '/' automatically) and if it is a valid format for an brazilian CNPJ, make sure to set the field type as unique, if necessary, when using it via Streams module or with Streams API. It will save as bigint, but accept and will return in CNPJ format '00.000.000/0000-00'
