复选框和单选按钮未针对laravel 5.6中的调查应用中的多个项目保存所选选项

Question

当我开始在调查中添加答案时没有在单选按钮和复选框上保存答案，并且只选择了一个带有复选框或单选按钮的问题。

一次只保存一个问题，或者某些时候保存null或“on”关键字对抗复选框或无线电答案。只能选择带复选框或单选按钮选项的第一个问题。

当我尝试选择其他问题的答案时，再次只选择了第一个问题选项，只有它们保存在db中。请检查代码和文件并帮助我。

当我尝试保存复选框或单选按钮选项时，只存储“on”关键字字符串。如果它们只是一个带文本的问题，则调查会运行，但是多个问题不能与其他问题一起使用

这是takeurvey.blade的视图

 @forelse($survey->questions as $key=>$question)
          <p class="flow-text">Question {{$key+1}} - {{$question->title}}</p>
          @if($question->question_type==='text')
          <div class="input-field col s12">
                        <input id="answer" type="text" name="{{$question->id}}[answer]">
