I'm developing an Infojobs style system, Catho and CEVIU in Wordpress, based on a Theme already created for this purpose. For a user to register on the site, by default the theme, he has to provide the following data: email, password, password confirmation and select in a field select if he is a company or candidate.
I need to implement another field, CPF or CNPJ according to what the user selects in the select.
I need to create another field in the WP database to send this data (CPF or CNPJ), what would be the most recommended table to send this information?
Does this field have to be created directly in the database or to use a WP custom fields?
Thank you.
