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="<?=$row->id_soal?>"></input>
<br><br>
<?php } ?>
<button class="btn btn-primary" type="submit">Submit</button>
<?php form_close(); ?>
and this is the code looks like when i try to inspect :
<input type="radio" name="jawaban1" value="A">A.Hamster</input><br>
<input type="radio" name="jawaban1" value="B">B.Tiger</input><br>
<input type="radio" name="jawaban1" value="C">C.Shark</input><br>
<input type="radio" name="jawaban1" value="D">D.Lion</input><br>
<br><br>
<input type="radio" name="jawaban2" value="A">A.was</input><br>
<input type="radio" name="jawaban2" value="B">B.have</input><br>
<input type="radio" name="jawaban2" value="C">C.am</input><br>
<input type="radio" name="jawaban2" value="D">D.is</input><br>
<br><br>
<button class="btn btn-primary" type="submit">Submit</button>
Here is my Controller looks like :
public function addKuisAnswer(){
if($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, $answer);
echo " <script>
alert('Jawaban Tugas Tersimpan!');
history.go(-2);
</script>";
}
Here is my model :
public function createAnswerKuis($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', $data);
}
I want the table looks like this :This is the picture of database table i made.I want to insert the data like this.
The problem is in Controller. How can my Controller post the value of radio button name="jawaban<?=$row->id_soal?>"in database?
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>";
}
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++;} ?>
Is this the question you meant :
How can i insert the value of radio button name="jawabanid_soal?>"in database?
or, how to read the value of the selected radio button and then insert it in the DB?
I will answer to both. To read the value of the answers you can go with foreach loop:
<?php
$egabat= array();
foreach($soalKuis as $row){
$egabat[$row->id_soal]= $_POST["jawaban".$row->id_soal];
} ?>
To insert the value in the DB, if this is MySql, then I recommend this very useful guide.
function insert($postdata) //modelfunction for insert
{
$array(
$tablevalues=
'filed1'=>$_POST["jawaban".$row->id_soal], // consider field1 as ur table field
);
$this->db->insert('table_name',$tablevalues);
}
You may put the value of $row->id_soal in hidden with the name array field when submitting the form then get the values of radio button with dynamic ids that come from the hidden field.
<?php
$egabat= array();
foreach($_POST['hiddenfield'] as $idsoal){
$egabat[$idsoal]= $_POST["jawaban".$idsoal];
} ?></div>
Here is the way to achieve this:
<?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="<?=$row->id_soal?>"></input>
<br><br>
<?php } ?>
<button class="btn btn-primary" type="submit">Submit</button>
<?php form_close(); ?>
and in controller you will have these values in an array which can be retrieve like:
<?php
foreach($this->input->post('jawaban') as $radio){
echo $radio;
}
