Hi @Vinnie Saletto
For your code to work, a user must exist in the DB with an ID of $user_id. If the facebook plugin is not creating a WP user, I don’t think the code will work.
It seems that using ACF for this part won’t help much, as you can’t edit the user in the backend anyway. Why not use native WP code like update_option to save . load the data into the wp_options table.
If you know the facebook user ID, you can use this in the options_name to construct the data name such as:
"{$facebookUserID}_rank"
Hope that helps
Thanks
