Hello,

I try for hours to create a function, which will display a small red dot on the nav-bars acitivity stream link, when someone posted something new. Since all users are logged in, it should be possible to work with metadata “last_activity_visit”.

What I tried:
Added below code to themes functions.php. Actually managed to display a red dot, when trying around with the code. But either the dot won’t be displayed at all, or it’s displayed always, even when the user visited the acitivity stream.

function track_activity_page_visit() {
    if (bp_is_activity_component()) {
        update_user_meta(get_current_user_id(), 'last_activity_visit', current_time('mysql'));
    }
}
add_action('wp', 'track_activity_page_visit');

function has_new_activity_posts() {
    $last_visit = get_user_meta(get_current_user_id(), 'last_activity_visit', true);

    if (empty($last_visit)) {
        return false;
    }

    $args = array(
        'date_query' => array(
            array(
                'after' => $last_visit,
            ),
        ),
        'max' => 1
    );

    $activities = bp_activity_get($args);

    if (!empty($activities['activities'])) {
        return true;
    }
    
    return false;
}

function add_red_dot_to_menu_buddypress_activity($items, $args) {
    if (is_user_logged_in() && has_new_activity_posts()) {
        foreach ($items as &$item) {
            if (strpos($item->url, '/activity/') !== false) {
                $item->title .= ' <span class="red-dot"></span>';
            }
        }
    }
    return $items;
}
add_filter('wp_nav_menu_objects', 'add_red_dot_to_menu_buddypress_activity', 10, 2);

Any clue? 🙂
