Hi there, please help me to solve this problem.

This is my Controller code :

class welcome extends CI_Controller {
function __construct(){
parent::__construct();
}

  function index(){
//use this for your homepage
$data['title']= "Welcome to claudia's kids";
$data['navlist']=$this->MCats->getAllCategoriesNav();
$this->load->vars($data);
$this->load->view('template');
}

This controller trying to load this model. This is my Model code :

class MCats extends CI_Model {

function __construct(){
parent::__construct();
}
 

  function getAllCategoriesNav(){
$data=array();
$Q=$this->db->get('categories');
if($Q->num_rows()>0){
foreach ($Q->result_array() as $row){
$data[$row['id']]=$row['name'];
}
      }
      $Q->free_result();
      return $data;
  }
}

Then i am entering the database configuration and change code in config/autoload.php

This is the code before :

/*
| -------------------------------------------------------------------
|  Auto-load Libraries
| -------------------------------------------------------------------
| These are the classes located in the system/libraries folder
| or in your application/libraries folder.
|
| Prototype:
|
| $autoload['libraries'] = array('database', 'session', 'xmlrpc');
*/

$autoload[‘libraries’] = array(’‘);

then i change the code something like this :

/*
| -------------------------------------------------------------------
|  Auto-load Libraries
| -------------------------------------------------------------------
| These are the classes located in the system/libraries folder
| or in your application/libraries folder.
|
| Prototype:
|
| $autoload['libraries'] = array('database', 'session', 'xmlrpc');
*/

$autoload[‘libraries’] = array(‘database’);

And I already have set the database configuration like this :

$active_group = ‘default’;
$active_record = TRUE;

$db[‘default’][‘hostname’] = ‘localhost’;
$db[‘default’][‘username’] = ‘root’;
$db[‘default’][‘password’] = ‘wicaksono’;
$db[‘default’][‘database’] = ‘shoppingcart’;
$db[‘default’][‘dbdriver’] = ‘mysql’;
$db[‘default’][‘dbprefix’] = ‘’;
$db[‘default’][‘pconnect’] = TRUE;
$db[‘default’][‘db_debug’] = TRUE;
$db[‘default’][‘cache_on’] = FALSE;
$db[‘default’][‘cachedir’] = ‘’;
$db[‘default’][‘char_set’] = ‘utf8’;
$db[‘default’][‘dbcollat’] = ‘utf8_general_ci’;
$db[‘default’][‘swap_pre’] = ‘’;
$db[‘default’][‘autoinit’] = TRUE;
$db[‘default’][‘stricton’] = FALSE;

Then here is the errors show on browsers :

A PHP Error was encountered

Severity: Notice

Message: Undefined property: welcome::$MCats

Filename: controllers/welcome.php

Line Number: 11

Fatal error: Call to a member function getAllCategoriesNav() on a non-object in C:\xampplite\htdocs\xampp\shopping\application\controllers\welcome.php on line 11

You need to change the following

Controller to CI_Controller
and
Model to CI_Model

You are autoloading the database, but you also need to load the model before making the function call:

$this->load->model('MCats');
