You would need to record each user’s views separately. For example a field for each user on every post that records the views for that user. Or you would need to have a field in usermeta for each user that records all of the posts viewed by that user.
Then you would need to check this field to see if a the view should be added before adding it.
Finally you would need to aggregate all of these values to show the total page views.
As an example, let’s say that I wanted to record this for each post. I would create a WP custom field that stores and array of user IDs that have viewed the page. When the page is loaded I would check this array to see if this user has viewed it.
$views = get_post_meta($post->ID, 'post_views', false);
if (empty($views)) {
$views = array();
}
$user_id = 0;
if (is_user_logged_in()) {
$user_id = get_current_user_id();
}
if (empty($views[$user_id])) {
$views[$user_id] = $user_id;
}
update_post_meta($post->ID, 'post_views', $views);
$total_views = count($views);
