How to insert many forms in db using Datatables - codeigniter

Question

I tried to submit many forms with datatables. User has to choose the number ot input rows, in which he can submit some information - it's something like Phpmyadmin when you insert rows in db. Names of the input rows are the same. I use loop to show many rows. But in this way with nested foreach, when I submit info in two rows, in database there are 8 rows. How to do that?
Here's my view:
echo form_open('admin/add_questions/');
?>
<table id='example'>
<thead>
<tr><th>Question</th><th>Code</th><th>Group</th><th>Is_reverse</th></tr>
</thead>
<tfoot>
<tr>
<th></th>
<th></th>
<th></th>
<th></th>
</tr>
</tfoot>
<tbody>
<?php for($i=0; $i<=20; $i++) {
?>
<tr>
<td>
<input type="text" name="question[]" id="add_question_table" />
</td><td>
<input type="text" name="code[]" id="add_question_table" />
</td><td>
<input type="text" name="group[]" id="add_question_table" />
</td><td>
<input type="text" name="is_reverse[]" id="add_question_table" />
</td></tr>
<?php
}
?>
</tbody>
</table>
My Model is:
<?php
class Admin_model extends CI_model {
public function __construct() {
parent:: __construct();
$this->load->database();
$this->load->library('session');
}
public function add_questions() {
$date = new DateTime("now");
foreach($this->input->post('question') as $v) {
foreach($this->input->post('code') as $f) {
foreach($this->input->post('group') as $val) {
$data = array(
'question'=>$v ,
'code'=>$f,
'survey_id'=>$this->uri->segment(3),
'group_id'=>$val,
'created_at'=>$date->format('Y-m-d H:i:s')
);
$this->db->insert('survey_questions',$data);
}
}
}
What's the way to do it? :)

Hi from my perspective its best to pass $_POST as a parameter to your add_questions() model method. You may try the following approach :)
//controller code
$this->admin_model->add_questions($_POST);
//model code
function add_questions($data=array())
{
if(count($data) > 0)
{
$date = new DateTime("now");
for($i=0;$i<count($data['question']);$i++){
$insert = array();
$insert['question'] = $data['question'][$i];
$insert['code'] = $data['code'][$i];
$insert['survey_id'] = $data['survey_id'][$i];
$insert['group_id'] = $data['group_id'][$i];
$insert['created_at'] = $date->format('Y-m-d H:i:s');
$this->db->insert('survey_questions',$insert);
}
}
}
