Thanks a lot for this. Just few notes. When in a real plugin it's worth to call these functions like

// custom user fields
add_action( 'user_new_form', array( $this,'crf_admin_registration_form' ) );
add_action( 'user_profile_update_errors', array( $this,'crf_user_profile_update_errors'), 10, 3 );
add_action( 'edit_user_created_user', array( $this,'crf_user_register') );
add_action( 'show_user_profile', array( $this,'crf_show_extra_profile_fields') );
add_action( 'edit_user_profile', array( $this,'crf_show_extra_profile_fields') );

Specifically take care of the 2 parameters of add_action( 'user_profile_update_errors', array( $this,'crf_user_profile_update_errors'), 10, 3 );, since it's a common error to write it down in the array...

Another question. How to make the custom fields editable in the User Profile page? So far the crf_show_extra_profile_fields is only showing the fields, but I cannot edit them in place.

Thanks for your code! it was a saver. Please I have a request.

I want to 3 more fields, that is Phone number, Gender and Address. Please any idea how to go about this? I tried adding it though but the result was zero (0) in the backend view.
I will be grateful for your support.
Thanks again

Merci beaucoup pour cela. Juste quelques notes. Quand dans un vrai plugin, cela vaut la peine d'appeler ces fonctions comme

// champs utilisateur personnalisés
 add_action ( ' user_new_form ' , array ( $ this , ' crf_admin_registration_form ' )); 
add_action ( ' user_profile_update_errors ' , array ( $ this , ' crf_user_profile_update_errors ' ), 10 , 3 ); 
add_action ( ' edit_user_created_user ' , array ( $ this , ' crf_user_register ' ));
add_action ( ' show_user_profile ' , array ( $ this , ' crf_show_extra_profile_fields ' )); 
add_action ( ' edit_user_profile ' , array ( $ this , ' crf_show_extra_profile_fields ' ));

Prenez en compte les 2 paramètres de add_action( 'user_profile_update_errors', array( $this,'crf_user_profile_update_errors'), 10, 3 );, car c'est une erreur courante de l'écrire dans le tableau ...

Une autre question. Comment rendre les champs personnalisés modifiables dans la page Profil utilisateur? Jusqu'à présent, il crf_show_extra_profile_fieldsne montre que les champs, mais je ne peux pas les modifier sur place.

Did you find the way to edit your custom fields after registration ?
