$this->load->helper(’url’);
$this->load->library(’session’);
$this->load->database();
$this->admin_url =$this->config->item(’admin_url’);
}

function index()
{

//load pagination class
$this->load->library(’pagination’);
$config[’base_url’] = $this->admin_url.’/contact_list/index/’;
$config[’total_rows’] = $this->db->count_all(’tbl_contact’);
$config[’per_page’] = ‘1’;
$config[’full_tag_open’] = ‘<p>’;
$config[’full_tag_close’] = ‘</p>’;

$this->pagination->initialize($config);

//load the model and get results
$this->load->model(’contact_model’);
echo $this->uri->segment(4);

$data[’results’] = $this->contact_model->get_books($config[’per_page’],$this->uri->segment(4));

$this->load->library(’table’);
$this->table->set_heading(’First Name’, ‘Last Name’, ‘Email’, ‘Contact Date’,’Action’);
