Question

public function index()
{
    $lesson= DB::table('lessons')
        ->select('long_text')
        ->join('courses', 'courses.lesson_id', '=', 'lessons.id')
        ->where('courses.title', $courses)
        ->get();

    return view(lesson.index);
}

在我的刀片中

<ul>
    <li style="text-transform: uppercase;"> {{$courses->title}} </li>
</ul>

点击标题后，它应该显示该课程的课程

Answer 1

您必须将数据返回到刀片：

public function index()
{
    $course= DB::table('lessons')
        ->select('long_text')
        ->join('courses', 'courses.lesson_id', '=', 'lessons.id')
        ->where('courses.title', $courses)
        ->get();

    return view(lesson.index, compact('course'));
}

然后，您可以使用以下代码段显示课程标题的内容
