CodeIgniter + Eclipse: Class 'Controller' and 'Model' not found

[Satish]

Error

Fatal error: Class 'Controller' not found in C:\wamp\www\CI\application\controllers\site.php on line 2


and


Fatal error: Class 'Model' not found in C:\wamp\www\CI\application\models\site_model.php on line 2


Solution:
Under models -> site_model.php

<?php
class Site_model extends Model {


function getAll(){
$q = $this->db->get('bbc');

    if( $q->num_rows() > 0 )
{ 
foreach($q->result() as $row)
$data[] = $row;
return $data;
}
}
}

?>

Under controllers -> site.php

<?php
 class Site extends Controller {
 
 function index() {
$this->load->model('site_model');
$data['records'] = $this->site_model->getAll();
$this->load->view('home',$data);
 }
 }
?>

In both the cases, add CI_ to Model and Controller

i.e., CI_Model and CI_Controller

Under models -> site_model.php

<?php
class Site_model extends CI_Model {

function getAll(){
$q = $this->db->get('bbc');

    if( $q->num_rows() > 0 )
{ 
foreach($q->result() as $row)
$data[] = $row;
return $data;
}
}
}

?>

Under controllers -> site.php

<?php
 class Site extends CI_Controller {
 
 function index() {
$this->load->model('site_model');
$data['records'] = $this->site_model->getAll();
$this->load->view('home',$data);
 }
 }
?>
