Retrieve data from checkboxes - php

Question

I want to get all the checked data from my table. I'm using checkboxes in my table. When I click "change status", it will change my role status.
But I have problems with retrieving the checkboxes values. In the code below, it failed to update my data. Checkboxes value that I retrieve is NULL. How can I solve this problem?
Model
function deaktifRole($id_role,$editBy)
{
$data = array(
'update' =>date('Y-m-d H:i:s'),
'updateBy' =>$editBy,
'flag' => '0'
);
$this->db->where('id_role',$id_role);
$this->db->update('tbl_role',$data);
}
Controller
function deaktifRole()
{
$session_data = $this->session->userdata('logged_in');
$editBy = $session_data['username'];
foreach ($this->input->post['pilih'] as $value) {
$this->Role->deaktifRole($value->value,$editBy);
}
redirect('Home/Role');
echo '<script>alert("Your form was successfully submitted!");</script>';
}
View
<div class="x_panel">
<div class="x_title">
<h2>Manage Staff Role</small></h2>
<?php echo form_open_multipart('Home/deaktifRole');?>
<div align="right">
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">Add</button>
<button type="submit" class="btn btn-primary">Change Status</button>
</div>
<div class="clearfix"></div>
</div>
<div class="x_content">
<table id="datatable-checkbox" class="table table-striped table-bordered bulk_action">
<thead>
<tr>
<th><input type="checkbox" id="check-all" class="flat"></th>
<th>No</th>
<th>Role</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<?php $j=0; foreach ($RoleList as $rows)
{
$j++;
?>
<tr>
<td><input type="checkbox" class="flat" name="pilih[]" value="<?php echo $rows['id_role']; ?>"></td>
<td><?php echo $j; ?></td>
<td><?php echo $rows['role']; ?></td>
<td>Aktif</td>
</tr>
<?php } ?>
</tbody>
</table>
</div>
<?php echo form_close(); ?>
</div>
</div>
</div>

Answer 1

As $this->input->post('pilih') is just an associative array, you can access it directly without ->value properties. Try use this code :
foreach ($this->input->post('pilih') as $value) {
$this->Role->deaktifRole( $value,$editBy );
}

Answer 2

use $this->input->post('pilih');
to fetch checkbox data.
