我如何在 Laravel 的同一视图中检索或返回不同的记录？

Question

请尝试在仪表板视图上检索事件数据和学生数据，但它们似乎相互冲突。学生记录也显示在我的事件记录应该显示的位置。这是它的样子：航线Route::post('/dashboard/submit', 'EventController@submit');Route::get('/dashboard', 'EventController@getevent');Route::post('/dashboard/student/pay', 'PaymentController@submit');Route::post('register','StudentRegister@register');Route::get('/dashboard', 'StudentRegister@getStudents');事件控制器.phpclass EventController extends Controller{    public function submit(Request $request)    {        $message = new Event;        $message->title = $request->input('title');        $message->deadline = $request->input('deadline');        $message->message = $request->input('message');        $message->save();        return redirect('/dashboard')->with('status', 'Event Added');    }    public function getevent()    {        $msgevent = Event::orderBy('id', 'DESC')->get();        return view('dashboard')->with('dashboard', $msgevent);    }}学生注册.phppublic function getStudents(){    $Students = Student::all();    return view('dashboard') -> with('dashboard', $Students);}

Answer 1

为什么用相同的名称调用两个事件。你改变你的代码如下。

studentRegister.php

public function getStudents(){

    $students = Student::all();

    $msgevents = Event::all()->orderBy('id', 'DESC');

    return view('dashboard', [

                     'students' => $students,

                     'msgevents' => $msgevents

               ]);

}

不要忘记use App\Event;在文件中添加。

dashboard.blade.php

<div class="paginate-no-scroll 5">

      <div class="items">

          @if(count($msgevents) > 0)

          @foreach ($msgevents as $msg)

        <div>

          <svg class="bd-placeholder-img mr-2 rounded" width="24" height="24" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid slice" focusable="false" role="img" aria-label="Placeholder: 32x32"><rect width="30%" height="30%" fill="#007bff"/><text x="50%" y="50%" fill="#007bff" dy=".3em"></text></svg>

          <p class="media-body pb-3 mb-0 small lh-125 border-bottom border-gray">

          <strong class="d-block text-gray-dark">{{$msg -> title}}</strong> | {{$msg -> deadline}} |<b style="color: #25027f"> @username</b> | <a href="#" style="text-decoration: underline;">Edit</a> | <a href="/delete/{!! $msg -> id !!}" style="text-decoration: underline;">Delete</a><br>

          {{$msg -> message}}

        </div>

         @endforeach

        @endif

<table id="tableData" class="table table-bordered table-striped">

          <thead>

    <th>#</th>

    <th>Student ID</th>

    <th>First Name</th>

    <th>Last Name</th>

    <th>Action</th>

  </thead>

    @if(count($students) > 0)

      @foreach ($students as $std)

  <tr>

    <td style="text-align:center"><img src="uploads/{{$std->image}}" style="width: 50px;height: 50px; border-radius: 50%" alt="{{$std->image}}"></td>

    <td style="text-align:center; padding-top: 25px;" >{{$std->studentID}}</td>

    <td style="text-align:center; padding-top: 25px;">{{$std->fName}}</td>

    <td style="text-align:center; padding-top: 25px;">{{$std->surName}}</td>

    <td style="text-align:center; padding-top: 25px;"><a href="" class="btn btn-primary"> view</a> 

    </td>

  </tr>

      @endforeach

      @endif

  </tbody>

        </table>

Answer 2

您在控制器中使用具有相同with变量的相同视图。dashboard

在 EventController.php getEvent 中：

return view('dashboard') -> with('dashboard', $msgevent);

在 studentRegister.php getStudents 中：

return view('dashboard') -> with('dashboard', $Students);

在各自的文件中将它们更改为更合适的名称，例如：

return view('dashboard') -> with('events', $msgevent);

return view('dashboard') -> with('students', $Students);

然后在您的blade文件中使用这些名称，例如：

<div class="paginate-no-scroll 5">

    <div class="items">

        @if($events && count($events) > 0)

        @foreach ($events as $msg)

        <div>

            <svg class="bd-placeholder-img mr-2 rounded" width="24" height="24" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid slice" focusable="false" role="img" aria-label="Placeholder: 32x32">

                <rect width="30%" height="30%" fill="#007bff"/>

                <text x="50%" y="50%" fill="#007bff" dy=".3em"></text>

            </svg>

            <p class="media-body pb-3 mb-0 small lh-125 border-bottom border-gray">

                <strong class="d-block text-gray-dark">{{$msg -> title}}</strong> | {{$msg -> deadline}} |<b

                    style="color: #25027f"> @username</b> | <a href="#" style="text-decoration: underline;">Edit</a> |

                <a href="/delete/{!! $msg -> id !!}" style="text-decoration: underline;">Delete</a><br>

                {{$msg -> message}}

        </div>

        @endforeach

        @endif

        <table id="tableData" class="table table-bordered table-striped">

            <thead>

            <th>#</th>

            <th>Student ID</th>

            <th>First Name</th>

            <th>Last Name</th>

            <th>Action</th>

            </thead>

            @if($students && count($students) > 0)

            @foreach ($students as $std)

            <tr>

                <td style="text-align:center"><img src="uploads/{{$std->image}}" style="width: 50px;height: 50px; border-radius: 50%" alt="{{$std->image}}"></td>

                <td style="text-align:center; padding-top: 25px;">{{$std->studentID}}</td>

                <td style="text-align:center; padding-top: 25px;">{{$std->fName}}</td>

                <td style="text-align:center; padding-top: 25px;">{{$std->surName}}</td>

                <td style="text-align:center; padding-top: 25px;"><a href="" class="btn btn-primary"> view</a>

                </td>

            </tr>

            @endforeach

            @endif

            </tbody>

        </table>
