I have a resource on my WordPress page that I only want to show X times per day per logged in user. I'm using the twenty sixteen WordPress theme.

Currently, Guests / visitors / non logged in users are forced via redirects to authenticate to my site in order to access any content.

How do impose a http request limit / pageview limit on a per-logged-in-user per day or per hour basis? I don't want to do it by IP address, I want to do it by unique user.

Has anyone seen this done? The closet I've seen is : https://premium.wpmudev.org/forums/topic/technical-question-how-to-limit-the-number-of-page-views-for-a-specific-site-under-a-wpmu-instsall#post-384060 but is there a solution already for this? I've searched for throttle, page view, http , limit, restrict, expire, but nothing seems to be restricting content on a logged-in-user-per-day-basis.

Thank you

**UPDATE: I am overriding the default page.php file of twenty sixteen theme to try to implement basic page-view limiting for logged-in users. However, When I log in and view any wordpress page, no entry is made to the wp_usermeta table. Why is there no "countVisitsUsed" field added to my user table when I view a page in wordpress? **

    <?php
//First, check for get_current_user_id.

$current_user = wp_get_current_user();
if ( 0 == $current_user->ID ) {
    //Not logged in
}   else {
        // Logged in.


        // create a log of visits by adding information to a user's metadata with update_user_meta & get_user_meta. 

        $COUNT_VISITS_TOTAL_LIMIT = 20; //each user may only view a page twenty times.

        if (get_user_meta($current_user, 'countVisitsUsed', true)) {
            $countVisitsUsed = get_user_meta($current_user,'countVisitsUsed',true);
            update_user_meta($current_user, 'countVisitsUsed', $countVisitsUsed+1);
        }else{
              update_user_meta( $user_id, 'countVisitsUsed', 1, false );
              $countVisitsUsed = get_user_meta($current_user,'countVisitsUsed',true);
        }


        if ($countVisitsUsed == null || $countVisitsUsed ==false || $countVisitsUsed < COUNT_VISITS_TOTAL_LIMIT) { //allow page load and increment their visit

            
            
            //start of page.php
