Answer 1

You need to add single quote on array key because it consider array key question as constant.

Your array should be like..

  $data = array(
          'question'=>$this->input->post('questions'),
          'answer1'=>$this->input->post('answer1'),
          'answer2'=>$this->input->post('answer2'),
          'answer3'=>$this->input->post('answer3'),
          'answer4'=>$this->input->post('answer4'),
          'answer5'=>$this->input->post('answer5'),
          'correctanswer'=>$this->input->post('correctanswer')
      );
   $this->db->insert('questionandanswers',$data);
