There are also several blog posts available on the subject that might be helpful:

• Adding Extra Fields to the WordPress User Profile

Ilplug-in Advanced Custom Fields Pro ti consentirà di aggiungere campi aiprofili utente senza alcuna codifica.

The Advanced Custom Fields Pro plugin will allow you to add fields to user profiles without any coding.

Farestimeglio a utilizzare get_user_meta (invece di get_the_author_meta ):

 function extra_user_profile_fields( $user ) {
    $meta = get_user_meta($user->ID, 'meta_key_name', false);
}
 

You'd better use get_user_meta (instead of get_the_author_meta):

function extra_user_profile_fields( $user ) {
    $meta = get_user_meta($user->ID, 'meta_key_name', false);
}
