<?php
class search extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper('url');

}
public function index()
{

$this->load->model('Model_form');
$this->load->helper('form');

$data['countries'] = $this->Model_form->get_countries();
$data['bodies'] = $this->Model_form->get_bodies();
$data['query']=$this->Model_form->trksearch();
$this->Model_form->display();
$data['query1']=$this->Model_form->display();
$data['query2']=$this->Model_form->display();
$data['query']=$this->Model_form->display();

$data['base_url']=base_url();
$this->load->view('trksearch',$data);

} ?>

this iz my model.php
<?php
class Model_form extends CI_Model
{
function __construct()
{
// Call the Model constructor
parent::__construct();
$this->load->database();
}
public function display()
{
$make = $this->input->post('mkno');
$model = $this->input->post('modno');

$this->db->select('mkcmpny');
$this->db->where('mkno',$make);
$query1=$this->db->get('mktruck');
return $query1->result();

$model = $this->input->post('modno');
$this->db->select('modnm');
$this->db->where('modno',$model);
$query2=$this->db->get('mkmodel');
return $query2->result();


$this->db->select('id,km,rgat,bdty,eprc,desr');
$this->db->where('mk',$make);
$this->db->where('md',$model);
$query=$this->db->get('tbl_sel');
return $query->result();

}
} ?>
