我想从我的表中获取所有选中的数据。我在我的表中使用复选框。当我单击“更改状态”时，它将更改我的角色状态。
但是我在检索复选框值时遇到了问题。在下面的代码中，它无法更新我的数据。我检索到的复选框值为NULL。如何解决这个问题？

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);
}

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>';
}
