有趣的是，在您昨天发布此内容几分钟后，我发现自己需要解决同样的问题，如您所见，上面的功能无法正常工作，并且在网上没有任何用处。简而言之，我花了一整天的时间试图找出原因，直到我意识到所有课程和测验也需要标记为完成，并且根据我对 learndash 源代码作为主要来源的研究编写了完全执行此操作的函数之后，我决定回到这里发布功能，以防万一你还没有修复它
Usage: sci_learndash_mark_course_complete($course_id, $user_id)
这是功能：
/**
* 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)

//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;
