是否可以创建这样的课程流程：
$(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 */

例如，我试图将这些放在content-learning.php我的子主题中的自定义中：
$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 但是当我切换到它工作的默认主题时，它需要什么样的“依赖”？为什么它不工作？
谢谢。
