Se devi aggiungere dei campi allo scarno menu di registrazione di woocommerce e in generale di wordpress bisogna modificare il file “functions.php” come di seguito indicato. Il fatto di essere riuscito ad inserire extra campi in registration form ha molto facilitato la registrazione.

“Se serve aggiungere campi (tipo p.iva, sdi) lo puoi fare con il plugin che si chiama: Checkout Field Editor for WooCommerce“

Nel caso sotto riportato è stato utilizzato il plugin Checkout Field Editor for WooCommerce per aggiungere i campi P.Iva e Società oltre a quelli già presenti.
