 '''Problem explanation:'''
 according to user.php => wp_update_user()
 in line // Add additional custom fields, the loop did do the job and read
 the custom fields into the array and store in $userdata, however,
 when wp_insert_user($userdata) read the data and insert the data into DB,
 the custom fields are gone and not being saved

 '''Cause of the problem:'''
 in wp_insert_user()
 because final data are using
 $data = compact( 'user_pass', 'user_email', 'user_url', 'user_nicename',
 'display_name', 'user_registered' );
 and this method exclude all the custom fields other than default
 variables.

 '''Suggested solution:'''
 add a foreach to read all the key name from $userdata at the beginning of
 wp_user_data()
 when using compact using foreach and $$var to create the array for output

 '''Workaround or other solution:'''
 I think most people are doing this using update_user_meta() to accomplish
 the job but if there is many fields, this might not be very effective.
