Question

您好我正在使用laravel php而我在我发送它的页面中没有得到我输入的值当我在我的控制器功能上dd（$ numexam）它告诉我它是空的。我是laravel和php以及编程的初学者

public function updatenote(Request $request){
  $num=$request->input('numexam');
  dd($num);
  $exam = Exam::find($num);
  $note=$request->input('note');
  $exam->note=$note;
  $exam->save();
  return Redirect::back();
}

这是我的路线web.php

    Route::get('/ajout', 'ExamsController@create');
    Route::post('/ajout', 'ExamsController@store')->name('exam.import');
    Route::get('/notemodifier', 'ExamsController@updatenote');

<!-- Button trigger modal -->
    <td>
    <button value="{{$verification->numexam}}" 
     onClick="document.getElementById('numexam').innerHTML=this.value" 
     type="button" class="btn btn-light" data-toggle="modal" data- 
     target="#exampleModalCenter">
     Update mark
     </button>
     </td>

我的观点要素：

<form action="/notemodifier" method="get">
  <input type="hidden" name="_token" value="{{ csrf_token() }}">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLongTitle">Modifier la note</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>

      <div class="modal-body">
        <center>
        <label>Taper la nouvelle note:</label>
        <input required type="text" name="note">
        </center>
        <input type="hidden" name="numexam" id="numexam">
      </div>

      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Fermer</button>
        <button  type="submit" class="btn btn-primary">Modifier</button>
      </div>
    </div>
</form>

  </div>
</div>

Answer 1

 Route::get('/notemodifier', 'ExamsController@updatenote');

将其更改为

 Route::post('/notemodifier', 'ExamsController@updatenote');

控制器中的

 public function updatenote(Request $request){
   $input = $request->all();
   dd($input);
   $exam = Exam::find($input['numexam']);
   $note=$input('note');
   $exam->note=$note;
   $exam->save();
   return Redirect::back();
 }

如何将模态文本输入的值发送到另一个页面？
