laravel - 未定义的变量Laravel（奇怪的情况）(Undefined variable Laravel (strange case))

Question

I am m having this annoying problem.

(我有这个烦人的问题。)

Can anyone give a hand to sort out it?

(谁能帮忙解决一下吗？)

I read all posts and I cannot find the solution.

(我阅读了所有帖子，但找不到解决方案。)

This is my controller

(这是我的控制器)

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use Auth;
use DB;
use AppPost;
use AppRegisteredCourse;

class DashboardsController extends Controller
{
    public function indexA()
    {

        return view('dashboards.admin-dashboard');
    }

    public function indexS()
    {
        $id = Auth::user()->id;
        $courses = DB::table('registered__courses')->select('user_id')->where('user_id', '=', $id)->count();
        $posts = Post::all();

        return view('dashboards.student-dashboard', compact('id', 'courses', 'posts'));
    }

    public function indexT()
    {

        return view('dashboards.teacher-dashboard');
    }
}

This is a fragment of the blade view.

(这是刀片视图的一部分。)

The name of the view is dashboards.student-dashboard

(视图的名称是dashboards.student-dashboard)

<div class="col-md-12">
  <div class="card">
    <div class="card-header">
      <h3 class="card-title">Posts</h3>
    </div>
    <div class="card-body">
      <div class="tab-content">
        <div class="active tab-pane" id="activity">
          <!-- Post -->
          <!--forEACH-->
          @foreach ($posts as $post)
            <div class="post">
              <div class="user-block">
                <span class="username">
                  <a href="#">{{$post->title}} | {{$post->author}}</a>
                </span>
                <span class="description">{{optional($post->created_at)->format('d-m-Y')}}</span>
              </div>
              <!-- /.user-block -->
              <p>
                {{$post->content}}
              </p>
            </div>
          @endforeach
        </div>
      </div>
    </div>
  </div>
</div>

And these are the routes

(这些是路线)

Route::group(['prefix' => 'dashboard',], function () {
    Route::get('/admin', 'DashboardsController@indexA')->name('dashboards.indexA');
    Route::get('/teacher', 'DashboardsController@indexT')->name('dashboards.indexT');
    Route::get('/student', 'DashboardsController@indexS')->name('dashboards.indexS');
});

I tried to pass al the variable to the view and I always have the same problem.

(我试图将变量传递给视图，但我始终遇到相同的问题。)

("Undefined variable").It seems like blocked the possibility to pass variable to the blade view.

(（“未定义的变量”）。似乎阻止了将变量传递到刀片视图的可能性。)

What I did before:

(我之前做过的事情：)

1-dd($posts) It does not working, it appears the exception "Undefined variable: posts".

(1-dd（$ posts）无效，出现“未定义变量：posts”异常。)

2- I remove the whole content of the blade file and I tried with a simple varible and it stills appearing the exception "Undefined variable".

(2-我删除了刀片文件的全部内容，并尝试使用一个简单的变量，它仍然出现异常“ Undefined variable”。)

3- I ran php artisan view:clear and restarted the server.

(3-我运行php artisan view：clear并重新启动服务器。)

Any sugestions?

(有任何建议吗？)

Thank you very much.

(非常感谢你。)
