如何在codeigniter中插入具有多个单选名称的单选按钮值？ [英] How to insert radio button value which is have multiple radio name in codeigniter?

问题描述

我正在尝试使用Codeigniter进行在线测验，其中包含一些主题的动态测验。用户可以在每个问题中添加问题和多项选择答案。如何在每个问题的每个多项选择答案中获得每个答案的价值？

I'm trying to making online quiz with codeigniter where there is a dynamic quiz with some subject. User can add the question and the multiple choice answer in each question. How can i get the value of each answer in each multiple choice answer on every question?

<?php echo form_open_multipart('c_kuis/addKuisAnswer'); ?>
       <?php foreach($soalKuis as $row){?>
            <?php $jawab_array = array($row->pil_a,$row->pil_b,$row->pil_c,$row->pil_d);
            ?>
            <p><?=$row->soal?></p>
            <input type="radio" name="jawaban<?=$row->id_soal?>" value="A">A.<?=$jawab_array[0]?></input><br>
            <input type="radio" name="jawaban<?=$row->id_soal?>" value="B">B.<?=$jawab_array[1]?></input><br>
            <input type="radio" name="jawaban<?=$row->id_soal?>" value="C">C.<?=$jawab_array[2]?></input><br>
            <input type="radio" name="jawaban<?=$row->id_soal?>" value="D">D.<?=$jawab_array[3]?></input><br>
            <input type="hidden" name="id_soal_kuis" value="<?=$row->id_soal?>"></input>
            <br><br>
       <?php } ?>
        <button class="btn btn-primary" type="submit">Submit</button>
      <?php form_close(); ?>

这是我尝试检查时的代码：

and this is the code looks like when i try to inspect :

            <input type="radio" name="jawaban1" value="A">A.Hamster</input><br>
            <input type="radio" name="jawaban1" value="B">B.Tiger</input><br>
            <input type="radio" name="jawaban1" value="C">C.Shark</input><br>
            <input type="radio" name="jawaban1" value="D">D.Lion</input><br>
            <br><br>

            <input type="radio" name="jawaban2" value="A">A.was</input><br>
            <input type="radio" name="jawaban2" value="B">B.have</input><br>
            <input type="radio" name="jawaban2" value="C">C.am</input><br>
            <input type="radio" name="jawaban2" value="D">D.is</input><br>
            <br><br>
                <button class="btn btn-primary" type="submit">Submit</button>

这是我的控制器看起来像：

Here is my Controller looks like :

public function addKuisAnswer(){
    if($this->session->userdata('data_user')->level != 1){
        redirect('/c_user/login');
    }
    $id_soal_kuis = $_POST['id_soal_kuis'];
    $id_user = $this->session->userdata('data_user')->id_user;
    $answer = $_POST['jawaban']; //The Problem's here... I should put jawaban with id_soal. Because the answer named 'jawaban1','jawaban2' etc it will follow the id_soal. How can i insert it?
    $this->load->model('m_kuis');
    $this->m_kuis->createAnswerKuis($id_soal_kuis, $id_user, $answer);
     echo " <script>
                    alert('Jawaban Tugas Tersimpan!');
                    history.go(-2);
                    </script>"; 

}

这是我的模型：

public function createAnswerKuis($id_soal_kuis, $id_user, $answer){
    $data = array(
        'id_soal_kuis'=>$id_soal_kuis,
        'id_user' => $id_user,
        'jawaban_kuis' => $answer            
    );
    $this->db->set('tgl_jawab', 'NOW()', FALSE);
    $this->db->insert('jawab_kuis', $data);
}

我希望表格如下所示：这是我制作的数据库表的图片。我要插入这样的数据。

I want the table looks like this :This is the picture of database table i made.I want to insert the data like this.

问题出在控制器中。我的控制器如何在数据库中发布单选按钮 name = jawaban<？= $ row-> id_soal？> 的值？

The problem is in Controller. How can my Controller post the value of radio button name="jawaban<?=$row->id_soal?>"in database?

推荐答案

我希望这个小小的改变对您有帮助

i hope this little change will helps you

 public function addKuisAnswer(){
        if($this->session->userdata('data_user')->level != 1){
            redirect('/c_user/login');
        }
        $id_soal_kuis = $_POST['id_soal_kuis'];
        $id_user = $this->session->userdata('data_user')->id_user;

        $this->load->model('m_kuis');
        $i=1;
    while(isset($_POST['jawaban'.$i]))
    {
         $answer = $_POST['jawaban'.$i];
//         var_dump($answer);
 $this->m_kuis->createAnswerKuis($id_soal_kuis, $id_user, $answer);
         $i++;
    }

         echo " <script>
                        alert('Jawaban Tugas Tersimpan!');
                        history.go(-2);
                        </script>"; 

    }

您可以按顺序更改单选按钮名称（因为在那里

you can change radio button name in sequential order(because there is no need of id appending in radio button)

 <?php 
$i=1;
    foreach($soalKuis as $row){?>
            <?php $jawab_array = array($row->pil_a,$row->pil_b,$row->pil_c,$row->pil_d);
            ?>
            <p><?=$row->soal?>
    <input type="hidden" value=<?php echo $row->id_soal?> name='id_soal'<?= $i ?>/></p>
            <input type="radio" name="jawaban<?=$i?>" value="A">A.<?=$jawab_array[0]?></input><br>
            <input type="radio" name="jawaban<?=$i?>" value="B">B.<?=$jawab_array[1]?></input><br>
            <input type="radio" name="jawaban<?=$i?>" value="C">C.<?=$jawab_array[2]?></input><br>
            <input type="radio" name="jawaban<?=$i?>" value="D">D.<?=$jawab_array[3]?></input><br>
            <input type="hidden" name="id_soal_kuis" value="<?=$row->id_soal?>"></input>
            <br><br>
       <?php $i++;} ?>
