关于使用personal_options_update 但为了安全起见，添加edit_user_profile_update 而且至于在WordPress中发送电子邮件，最好的方法是使用wp_mail, 比如：

add_action( \'personal_options_update\', \'notify_admin_on_update\' );
add_action( \'edit_user_profile_update\',\'notify_admin_on_update\');
function notify_admin_on_update(){
    global $current_user;
    get_currentuserinfo();

    if (!current_user_can( \'administrator\' )){// avoid sending emails when admin is updating user profiles
        $to = \'[email protected]\';
        $subject = \'user updated profile\';
        $message = "the user : " .$current_user->display_name . " has updated his profile with:\\n";
        foreach($_POST as $key => $value){
            $message .= $key . ": ". $value ."\\n";
        }
        wp_mail( $to, $subject, $message);
    }
}
