Flushing cache for specific MyCred users

By default, WP-Optimize doesn’t support clearing the cache for individual users when their MyCred balance changes—it’s usually an all-or-nothing process, or it can target specific URLs. However, we might be able to work around this if each user on your site has their own unique profile URL.

If your users do have their own specific profile pages, we could potentially target and clear the cache just for those pages. This way, only the cache for the affected user gets cleared, without impacting others.

To flush the cache for specific users, you can modify the snippet you mentioned to target only the cache for the affected user’s profile page. Since each user has a unique profile URL, we can clear the cache for that specific URL instead of purging the entire cache. Here’s how you can modify the snippet:

add_filter('mycred_add_finished', 'check_for_balance_change_and_purge_user_cache', 1000, 3);
function check_for_balance_change_and_purge_user_cache($reply, $request, $mycred) {
    if ($reply === true) {
        $user_id = $request['user_id']; // Assuming user ID is passed in $request
        $user_profile_url = get_author_posts_url($user_id); // Adjust this if the profile URL is different
        WPO_Page_Cache::delete_single_post_cache_by_url($user_profile_url);
    }
    return $reply;
}

This approach will ensure that only the cache for the specific user who had their MyCred balance changed is purged, leaving other users’ cache intact. This should help maintain the performance of your site while ensuring that the correct data is displayed for the user whose balance has changed.

Note:
We’re exploring a code snippet that falls outside the typical scope of WP-Optimize’s core functionalities. While WP-Optimize is designed with clear and defined functions, this custom approach might help achieve your specific goal of flushing the cache for individual users based on their MyCred balance changes. Please be aware that, as this is a custom implementation, it may or may not work perfectly with your setup. We recommend testing it thoroughly on a staging site before applying it to your live environment.

You’re right—the code provided will only purge the cache for the specific user’s profile page when their MyCred balance changes. However, extending this to purge other pages, like those involving the OptinSpin plugin, would require a more customized approach.

While WP-Optimize doesn’t natively support purging cache for multiple specific pages tied to a user, it might be possible with custom development. This is a bit outside the typical scope of WP-Optimize’s functionality, so I’d recommend consulting with a developer to explore this further if you need a tailored solution.

Thank you for the details and for understanding the current limitations. Given the functionality available in WP-Optimize, I’ve adjusted the approach to target your specific user profile pages.

You can use the following snippet, which converts your profile URL into a post ID and then purges the cache for that specific post:

add_filter('mycred_add_finished', 'check_for_balance_change_and_purge_user_cache', 1000, 3);
function check_for_balance_change_and_purge_user_cache($reply, $request, $mycred) {
    if ($reply === true) {
        $user_id = $request['user_id']; // Assuming user ID is passed in $request
        $user_profile_url = home_url('/profile/' . $user_id . '/');
        $post_id = url_to_postid($user_profile_url); // Convert the URL to a post ID

        if ($post_id) {
            WPO_Page_Cache::delete_single_post_cache($post_id); // Purge the cache for that specific post ID
        }
    }
    return $reply;
}

This snippet will ensure that the cache is purged specifically for the user’s profile page without affecting other users or pages. It should help keep your site performing well while displaying accurate data for users.

Please test this on a staging environment first to make sure it integrates smoothly with your setup.
