Completed Courses Solution Deprecated?

Thomas, can you or a colleague possibly expand on the suggestion you gave me in slack?

You suggested I use this filter: https://github.com/gocodebox/lifterlms/blob/2c9a6f581350de280ba8eb2fe141000301738712/includes/functions/llms.functions.templates.dashboard.php#L218-L236

You suggested looping through the courses pulled into post__in, and then use this:https://developer.lifterlms.com/reference/classes/llms_student/get_progress/ to check the progress of each course, and drop the courses that are completed.

That sounded simple enough. I’m used to working in Js and Js frameworks, and immediately I’m thinking of iterating over the array ($courses) with something like the map method, creating a new array of those that are complete, and returning them to be displayed in a ‘Completed’ section, while also dropping them from the main ‘My Courses’ array.

The problem I’m running into is just a lack of familiarity with the WordPress ecosystem, and not knowing where to call that filter from, and accessing post__in to iterate over the courses. I’m using lifterlms customizer. Is that the best route? Are filters and that array available globally? Do they have to be imported to be used? I’m not intimidated by this, and I know what I want to do, just learning the inner workings of WP.

Then I saw a more direct and to-the-point solution that I referenced in my OP. Is something like that still feasible? Because I don’t want to ONLY drop courses, but I want display completed courses in a new section, and that seemed very simple. I just didn’t see the referenced files in the directory.

Any help is appreciated, as this is for a paid installation of LifterLMS, so it’s not just someone trying to learn with your free plugin.

Thanks!
