WordPress网站添加用户记录

WordPress网站添加用户注册IP，最后一次登录IP，手机号码等记录。

在主题functions.php中添加以下代码

/** 
 * add the register record. 
 */  
function get_client_ip() {  
    if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))  
        $ip = getenv("HTTP_CLIENT_IP");  
    else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"),  
"unknown"))  
        $ip = getenv("HTTP_X_FORWARDED_FOR");  
    else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown"))  
        $ip = getenv("REMOTE_ADDR");  
    else if (isset ($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR']  
&& strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))  
        $ip = $_SERVER['REMOTE_ADDR'];  
    else  
        $ip = "unknown";  
    return ($ip);  
}  
// 创建一个新字段存储用户注册时的IP地址  
add_action('user_register', 'log_ip');  
function log_ip($user_id){  
    $ip = get_client_ip();  
    update_user_meta($user_id, 'signup_ip', $ip);  
}  
// 创建新字段存储用户登录时间和登录IP  
add_action( 'wp_login', 'insert_last_login' );  
function insert_last_login( $login ) {  
    global $user_id;  
    $user = get_userdatabylogin( $login );  
    update_user_meta( $user->ID, 'last_login', current_time( 'mysql' ) );  
    $last_login_ip = get_client_ip();  
    update_user_meta( $user->ID, 'last_login_ip', $last_login_ip);

    unset($columns['name']);//移除“姓名”这一栏，如果你需要保留，删除这行即可  
    return $columns;
