如何在Archive.php中显示用户的状态(在线-离线)

我正在使用代码用户状态How to check if a user (not current user) is logged in?. 在作者的个人资料页面上，效果很好（谢谢大家）。但如果我把它放在文章底部的存档页上，它就不起作用了

functions.php

add_action(\'wp\', \'update_online_users_status\');
function update_online_users_status(){

    if(is_user_logged_in()){

        if(($logged_in_users = get_transient(\'users_online\')) === false) $logged_in_users = array();

        $current_user = wp_get_current_user();
        $current_user = $current_user->ID;  
        $current_time = current_time(\'timestamp\');

        if(!isset($logged_in_users[$current_user]) || ($logged_in_users[$current_user] < ($current_time - (15 * 60)))){
            $logged_in_users[$current_user] = $current_time;
            set_transient(\'users_online\', $logged_in_users, 30 * 60);
        } 
    }
}

author.php

<?php
function is_user_online($user_id) {

    // get the online users list
    $logged_in_users = get_transient(\'users_online\');

    // online, if (s)he is in the list and last activity was less than 15   minutes ago
    return isset($logged_in_users[$user_id]) && ($logged_in_users[$user_id] >     (current_time(\'timestamp\') - (15 * 60)));   
}

$passthis_id = $curauth->ID;
if(is_user_online($passthis_id)){echo \'User is online.\';}
else {echo\'User is not online.\';}
?>

EDIT OP希望“在归档页面的每篇文章底部显示状态”。

function is_user_online( $user_id ) { // get the online users list $logged_in_users = get_transient( \'users_online\' ); // online, if (s)he is in the list and last activity was less than 15 minutes ago return isset( $logged_in_users[$user_id] ) && ( $logged_in_users[$user_id] > ( current_time( \'timestamp\' ) - ( 15 * 60 ) ) ); }

Track logged in users' visits

是否有方法跟踪登录的用户活动？我想看看谁每天都登录到这个网站，也许还能看到特定的人的登录历史。目前我不知道哪些注册用户正在访问我的网站。这是一个私人家庭网站~20 members 我只是想知道谁在使用它，谁没有使用它。
