How To Add Multiple Questions And Answers To Mysql Using Yii?

Hi I have to insert multiple questions and answers,when i click add new question or answer it will append new for like below

Ques 1:

ans 1,

ans 2, > add answer

Ques 2:

This is my form structure,and i have two mysql tables for questions and answer separately then i have to insert ques to questions and ans to answers

here is my controller


public function actionAdd_quick()


{

     $model=new Question;

     $answers=new Answers;

    if(isset($_POST['Question']))

    {

        $model->attributes=$_POST['Question'];  

         $answers->attributes=$_POST['Answers'];

        foreach ($model['questions'] as $value) {

          $model=new Question;

          $model->questions = $value;

          $model->save();


        foreach ($answers['answer'] as $ans) {

            $answers=new Answers;

            $answers->answer = $ans;

            $answers->question_id=$model->id;

            $answers->save();

        }

    }


    Yii::app()->user->setFlash('add_quick','Thank you for ');
