Laravel将值从下拉列表发送到控制器

I have the following code in my view page

 <form action="{{ action('AnswerController@handleCreate') }}" method="post" role="form">
        <div class="form-group dropdown">
            <label for="question">Question</label>
            <select  id="question" class="drop" name="question">
                @foreach($questions as $question)

                    <option value="{{$question->question}}">{{$question->question}}</option>

                @endforeach
            </select>
        </div>

in my controller i have the following code

$question = Question::whereQuestion(Input::get('question'))->first();

$n = $question->id;

They give me an error at $n=$question ->id telling trying to get property of non-object

我在视图页面中有以下代码

 &lt  ; form action =“{{action('AnswerController @ handleCreate')}}”method =“post”role =“form”&gt; 
&lt; div class =“form-group dropdown”&gt; 
&lt; label  for =“question”&gt;问题&lt; / label&gt; 
&lt; select id =“question”class =“drop”name =“question”&gt; 
 @foreach($ questions as $ question)
 
&lt  ; option value =“{{$ question-&gt; question}}”&gt; {{$ question-&gt; question}}&lt; / option&gt; 
 
 @endforeach 
&lt; / select&gt; 
&lt;  / div&gt; 
   
 
 

在我的控制器中我有以下代码

  $ question = Question :: whereQuestion( 输入:: get('问题')) - &gt; first(); 
 
 $ n = $ question-&gt; id; 
   
 
 

他们给出 我错误$ n = $ question - &gt; id告诉我试图获取非对象的属性
