WordPress: LearnPress (LMS plugin)：查询与'course‘相关的'lessons’

Question

我希望使用WordPress的LearnPress LMS插件来查询与特定“课程”相关的“课程”。

例如，如果我的‘Course’ID是“123”，我如何获得相关'Lessons‘的列表？

谢谢。

Answer 1

可能会很晚，但我在寻找相同的解决方案几个小时后，将答案留在了这里。

LearnPress版本: 3.2.6.7

WordPress版本: 5.3.2

<?php

// Get the course instance.
$course = learn_press_get_course( $course_id );

// Get the curriculum of the course.
$curriculum = $course->get_curriculum();


// Iterate over the curriculum sections.
foreach ( $curriculum as $section ) {
    // Get the lessons associated with the section.
    $lessons = $section->get_items();

    // Iterate over each lesson.
    foreach ( $lessons as $lesson ) {
        // Now you can work with each lesson, for example:

        // Get the lesson ID.
        $lesson_id = $lesson->get_id();
    }
}

?>

我希望它能有所帮助！
