wp_update_user

Обновляет данные пользователя в базе данных. Обновляются обе таблицы wp_usermetaи  wp_users.

Если обновляется пароль текущего пользователя, то куки будут сброшены.

Если в $userdata не указан параметр ID, то будет создан новый пользователь с указанными данными. С версии 3.6 такое создание пользователя больше не работает (возможно эта функция будет возвращена в будущем), поэтому чтобы создать нового пользователя используйте функцию wp_create_user().
Хуки из функции:
auth_cookie_expiration
email_change_email
password_change_email
send_email_change_email
send_password_change_email
Возвращает

ID пользователя или WP_Error объект.

Использование

<?php wp_update_user( $userdata ) ?>
$userdata(массив)
Массив данных, которые нужно обновить.
По умолчанию: данные пользователя.

Примеры

#1. Обновим поле: website у пользователя 1:
