model not inserting select option

My model is not inserting my modify and access data that I select on my view.If my select option on my view is select option 1 it inserts value 0 even though 1 selected. Not sure why on model or view its not inserting the correct one?

Each controller has its own modify and access select option i would like to be able to insert if select 1 for enable or 0 disbale?

How can I make the both select options work with my model so inserts correct what have chosen.

Model Function

<?php

class Model_user_group extends CI_Model {

public function addUserGroup() {

    $name = $this->input->post('name');
    $controllers = $this->input->post('controller');   
    $access = $this->input->post('access');
    $modify = $this->input->post('modify');

    for($i=0;$i<count($controllers);$i++) { 

    $data = array(
        'name' => strtolower($name),
        'controller' => $controllers[$i],
        'access' => $access,
        'modify' => $modify
    );


    $this->db->insert($this->db->dbprefix . 'user_group', $data);

    }

}

Your view file seems has access and modify option for each controller. But your input name is same.So the value of $access and $modify is the last input value. You can solve this way.Give access and modify input name as array

<select name="access[]" class="form-control">
...
<select name="modify[]" class="form-control">

Now your model

$name = $this->input->post('name');
$controllers = $this->input->post('controller');   
$accesses = $this->input->post('access');
$modifies = $this->input->post('modify');

for($i=0;$i<count($controllers);$i++) { 

  $data = array(
    'name' => strtolower($name),
    'controller' => $controllers[$i],
    'access' => $accesses[$i],
    'modify' => $modifies[$i]
   );


   $this->db->insert($this->db->dbprefix . 'user_group', $data);

}

Hope you understand and solves your problem
