I have a controller:
class Blah extends Controller
{
function Blah()
{
$this->load->model('baga_model');
}
}
then comes baga_model:
class Baga_model extends Model
{
function do_it()
{
echo "BOOM!";
}
}
..and
class Blah_model extends Model
{
function some_action()
{
$this->baga_model->do_it();
}
}
So .. when in blah_model I call $this->baga_model->do_it() I get an error :
Call to a member function do_it() on a non-object
I just can't understand why.... I know it must work, I did something similar before..
Thanks
Got it! I had to load baga_model in blah_model constructor. This way it works.
Thanks everyone.
public function test()
{
$this->load->model('baga_model');
$this->baga_model->do_it();
}
Model
class baga_model extends CI_Model
{
public function do_it()
{
echo $this->bar("BOOM!");
}
Your not loading your required model inside your model:
class Blah_model extends CI_Model
{
$this->baga_model = $this->load->model('baga_model', true);
public function some_action()
{
$this->baga_model->do_it();
}
}

contrller:News.php
This is my controller News

public function __construct()

public function getShowIN_News()
{
return $result;
} } ?>

This is my controller Category

By using an empty constructor, you're making it so that CI_Controller::__construct() isn't called, and that's where everything in the framework is initialized.
I know you've put it there to hack it so you can call one controller from another, but it is very intentionally made that way, exactly so you don't do this.
What I'm trying to do on the surface seems simple, basic OOP PHP but I just can't get it working. I have a controller class which is calling a model, that model extends another model of mine but it throws an error saying it can't find it:
Controller (Welcome.php):
public function __construct()
{
parent::__construct();
$this->load->model('users_model');
}
public function index()
{
$this->users_model->getAll();
}
Users Model (User_model.php):
class Users_model extends Base_model
{
public function __construct()
{
parent::__construct();
}
}
Base Model (Base_model.php):
class Base_model extends CI_Model
{
public function __construct()
{
parent::__construct();
$this->load->database();
}
public function getAll($table)
{
$query = $this->db->query('Query here');
return $query;
}
}
This gives me the error Fatal error: Class 'base_model' not found in /ci/application/models/Users_model.php on line 3
Save your Base_model in application/core named as Base_model.php with following code.
class Base_model extends CI_Model
{
public function __construct()
{
parent::__construct();
$this->load->database();
}
public function getAll($table=FALSE)
{
$query = $this->db->query('Query here');
return $query;
}
}
Save User_model in application/models named as User_model.php having following code
class User_model extends Base_model
{
public function __construct()
{
parent::__construct();
}
}
Then make a controller Welcome.php in appliation/controllers having following code with extending CI_Controller
public function __construct()
{
parent::__construct();
$this->load->model('user_model');//loads user_model
}
public function index()
{
$data = $this->user_model->getAll(); //need a variable to hold return data
}
You just have to locate the Base_model in your Users_model like below code and you can access the functions of base model easily.
require('application/models/base_model.php');
class User_model extends Base_model
{
function __construct()
{
parent::__construct();
}
}
I have the following simplistic code:
// FILE: controllers/Top.php
class Top extends MY_Public_Controller {
function __construct() {
}
public function Top() {
echo 'Hello';
}
}
// FILE: application/core/MY_Public_Controller.php
class MY_Public_Controller extends MY_Controller {
function __construct() {
parent::__construct();
}
}
// FILE: application/core/MY_Controller.php
class MY_Controller extends CI_Controller {
function __construct() {
parent::__construct();
}
}
And I get the following the following error:
Fatal error: Class 'MY_Public_Controller' not found in
/var/www/example.com/public_html/application/controllers/Top.php on line 5
A PHP Error was encountered
Severity: Error
Message: Class 'MY_Public_Controller' not found

Any help would be much appreciated!
Instead of you create a new file (MY_Public_Controller.php) to create the class My_Public_Controller.
Insert this class inside the My_Controller.php file.
In that way the My_Controller.php file will be like:
class MY_Controller extends CI_Controller {
function __construct() {
parent::__construct();
}
}
class MY_Public_Controller extends MY_Controller {
function __construct() {
parent::__construct();
}
}
After I see another answer
Or you can make something like #Hikmat Sijapati said, but instead of you put the require_once, inside the My_Controller.php. Try to put it in the My_Public_Controller.php using 'My_Controller.php' as parameter. Something like that:
My_Public_Controller.php:
include_once('My_Controller.php');
class MY_Public_Controller extends MY_Controller {
function __construct() {
parent::__construct();
}
}
I have not tried it that way, but I think it will work.
Try like this...
You can create any number of controller but create controller's must be included in the controller that extends CI_Controller.As Below:
Controller's Name and function Name Keep different (Good Way)
MY_Controller:application/core/MY_Controller.php
class MY_Controller extends CI_Controller {
function __construct() {
parent::__construct();
}
include_once('MY_Public_Controller.php');// include here
}
MY_Public_Controller: application/core/MY_Public_Controller.php
class MY_Public_Controller extends MY_Controller {
function __construct() {
parent::__construct();
}
}
And Top: application/Top.php
class Top extends MY_Public_Controller {
function __construct() {
}
public function index() { //function name must be different than controller's name
echo 'Hello';
}
}
I have mystical error with MySQL query. I'm using CI php-framework.
This is my function in controller:
public function editParam($id_article_params='')
{
if(IS_AJAX)
{
$this->load->model('Article_params_model','article_params');
$this->article_params->updateSizeById($id_article_params,$_GET['size']);
}
}
Article_params model:
class Article_params_model extends CI_Model
{
public function updateSizeById($id_article_params,$size)
{
$this->db->query("UPDATE article_params SET size='".$size."' WHERE id_article_params='".$id_article_params."'");
}
}
I'm trying to get error but error not isset. For example, next function also in Article_params_model but work!
public function all()
{
return $this->db->query("SELECT * FROM article_params");
}
In Article_params model put below code.
class Article_params_model extends CI_Model
{
public function updateSizeById($id_article_params,$size)
{
$this->db->where('id_article_params', $id_article_params);
$this->db->update('article_params', $size);
}
}
class Article_params_model extends CI_Model
{
public function updateSizeById($id_article_params,$size)
{
$this->db->where('id_article_params', $id_article_params);
$this->db->update('article_params', $size);
}
}
I'm using the following from the controller to call a method from the model but receiving and error:
//from the controller:(main.php)
<?php
class Main extends CI_Controller {
public function __construct() {
parent::__construct();
}
function index() {
.....
$this->load->view('view_form');
}//END Fn index()
function get_th() {
//$the=$this->input->post('th', TRUE);
$d['shit']=$this->model_data->tst();
$this->load->view('view_form',$d);
}//END Fn get_th()
}//END Cls Main
?>
//from the model:(model_data.php)
<?php
class Model_data extends CI_Model {
function slider() {
...
}//END Fn slider()
function check_input($data) {
...
}//END Fn check_input()
function tst() {
$tsts= "hellos";
return $this->tsts;
}
}//END Cls model_data
?>
$autoload['model'] = array('model_data');
The error:
Fatal error: Call to undefined method Model_data::tst() in ... application\controllers\main.php...
i think you forgot to load the model in the controller.
$this->load->model('Model_name');
function get_th() {
$this->load->model('model_data');
$d['shit']=$this->model_data->tst();
$this->load->view('view_form',$d);
}
FIXED :/ can t believe I had an additional bracket at the the end of a long file :( wtf
"}"<-- this was the problem.
btw as I said #pramodhkumar use autoload.php.. I had the model autoload so no need for $this->load->...
