Funny enough, i found myself needing solution to same problem minutes after you posted this yesterday and as you see, that function above failed to work and nothing useful online. In short, i spent the whole day on it trying to find why until i realized all lessons and quiz need to be marked as complete too and after writing the function that do exactly this based on my research on learndash source code as primary source, i decided to come back here and post the function just incase you haven't fix it
Usage: sci_learndash_mark_course_complete($course_id, $user_id)
Here's the function:
/**
* Mark learndash course as complete.
*
* @param int $id Course ID.
* @param int $user_id User ID.
*/
function sci_learndash_mark_course_complete($id, $user_id)
{
//retreive current course progress
$user_progress['course'][$id] = learndash_user_get_course_progress($user_id, $id, 'legacy');
if (isset($user_progress['course'][$id]['lessons'])) {
//update lessons progress to complete
$lesson_array = $user_progress['course'][$id]['lessons'];
$lessons = array_flip($lesson_array);
$lessons = array_fill_keys(array_keys($lesson_array), 1);
$user_progress['course'][$id]['lessons'] = $lessons;
}
//update topics progress to complete
if (isset($user_progress['course'][$id]['topics'])) {
foreach($user_progress['course'][$id]['topics'] as $ldtopic_key => $ldtopic){
if(count($ldtopic) > 0){
$new_ldtopic = array_flip($ldtopic);
$new_ldtopic = array_fill_keys(array_keys($ldtopic), 1);
$user_progress['course'][$id]['topics'][$ldtopic_key] = $new_ldtopic;
}
}
}
//update quiz progress to complete
