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"))

    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'];
