-->
        <input class="form-control" name="question_title1" type="text" id="question_title" 
        value="" required>

    {!! $errors->first('question_title1', '<p class="help-block">:message</p>') !!}
    </div> <br>  <br>

控制器QuizController.php的一部分：

   public function store(StoreQuizRequest $request)
    {

    $data_quiz = $request->only(
    'title', 'description', 'category', 'published',  'access', 'start_date', 'end_date',
    'duration','show_answers');

    $data_quiz['user_id'] = Auth::user()->id;

    $quiz = Quiz::create($data_quiz);




 $question_1['question_title']=$request->question_title1;
 $question_1['question_description']=implode('|&-&|',$request->question_description1);
 $question_1['question_answer']=implode('|',$request->question_answer1);
 $question_1['quiz_id'] = $quiz->id;


 $question_2['question_title']=$request->question_title2;
 $question_2['question_description']=implode('|&-&|',$request->question_description2);
 $question_2['question_answer']=implode('|',$request->question_answer2);
 $question_2['quiz_id'] = $quiz->id;



 $question_save1 = Question::create($question_1);
 $question_save2 = Question::create($question_2);

 return redirect('quiz')->with('flash_message', 'Quiz created!');


    }

让我们看一下：How do I create arrays in a HTML ？

您可以创建这样的表单，如果添加了更多问题，则复制表单组：

<div class="form-group">
    ....
    <input name="question_title[]" />

    A. <input name="question_descriptionA[]" type="text" id="question_descriptionA" value="a1" />
    <input type="checkbox" name="question_answerA[]" value="1" checked /> <br />

    B. <input name="question_descriptionB[]" type="text" id="question_descriptionB" value="a2" />
    <input type="checkbox" name="question_answerB[]" value="2" /> <br />

    C. <input name="question_descriptionC[]" type="text" id="question_descriptionC" value="a3" />
    <input type="checkbox" name="question_answerC[]" value="3" /> <br />

    D. <input name="question_descriptionD[]" type="text" id="question_descriptionD" value="a4" />
    <input type="checkbox" name="question_answerD[]" value="4" /> <br />
    ....
</div>

您可以按如下方式访问请求数据：

$data = $request->only('question_title',
    'question_descriptionA', 'question_answerA', 
    'question_descriptionB', 'question_answerB', 
    'question_descriptionC', 'question_answerC', 
    'question_descriptionD', 'question_answerD');
