是否可以创建像这样的课程流程：
$(document).ready(function() {
$("div.bhoechie-tab-menu>div.list-group>a").click(function(e) {
e.preventDefault();
$(this).siblings('a.active').removeClass("active");
$(this).addClass("active");
var index = $(this).index();
$("div.bhoechie-tab>div.bhoechie-tab-content").removeClass("active");
$("div.bhoechie-tab>div.bhoechie-tab-content").eq(index).addClass("active");
});
});/* bhoechie tab */

如果可能的话，您能帮我参考一下如何提取所有课程数据（课程预览，课程及其所有内容）吗？我可以使用get_posts来做到这一点，但是我不确定这是一个好方法，因为LearnPress具有许多安全检查功能和课程进度等。
例如，我正尝试将它们放在我的子主题的自定义content-learning.php中：
$user = LP_Global::user();
$course_item = LP_Global::course_item();
$course = LP_Global::course();
$can_view_item = $user->can_view_item( $course_item->get_id(), $course->get_id() );
echo '<pre>';var_dump( $course_item );echo '</pre>';
var_dump( $course_items );返回null，但是当我切换到默认主题时，它需要什么样的“依赖关系”？为什么它不起作用？
谢谢。
