A PHP Error was encountered
Severity: Notice
Message: Undefined property: Settings::$common_model
Filename: controllers/settings.php
Line Number: 24
Fatal error: Call to a member function get_user_settings() on a non-object in D:\xampp\htdocs\dandalo\application\controllers\settings.php on line 24
This is my code. I am getting this error. I dont know how come this kind of error when I load the model correctly.
Model Code:
<?php
class common_model extends CI_Model
{
public $datet;
public function __construct()
{
parent::__construct();
$this->load->database();
//$this->load->model('buy_model');
$this->datet=date('Y-m-d H:i:s');
}
function get_user_settings()
{
$this->db->select('user_name,u_first_name,u_last_name,u_email,u_profile_image,fb_id');
$this->db->where('user_id',user_id());
return $this->db->get('en_user')->result();
}}?>
This is my model code. I also extended the CI_model. still I am getting error.
locate your model in application/models
profile_model.php
common_model.php
your model class looks like
class ProfileModel extends CI_Model
class CommonModel extends CI_Model
load in controller
$this->load->model('profile');
$this->load->model('common');
then call model function
$data['settings']=$this->common->get_user_settings();
For more :- http://ellislab.com/codeigniter/user-guide/general/models.html
Your model class name should be Start with first latter uppercase, It should be
class Common_model extends CI_Model
OR
class Common_Model extends CI_Model
Instead of
class common_model extends CI_Model
Where Model_name is the name of your class. Class names must have the first letter capitalized with the rest of the name lowercase. Make sure your class extends the base Model class.

This is my model named Userhome_model.php
class Userhome_model extends CI_Model {
function Userhome_model() {
parent::__construct();
I tried to call this in my controller like
this->load->model('Userhome_model');
But i got an error like
Unable to locate the model you have specified: userhome_model
Change this to
this->load->model('Userhome_model');
this
this->load->model('userhome_model');
this will fix the issue(How to load model)
and Model should be place inside application/model
File Name - userhome_model.php
Inside userhome_model
class Userhome_model extends CI_Model {
public function __construct()
{
parent::__construct();
}
}
Using model
this->model_name->method();
Well, I'm newbie in CodeIgniter Framework and i'm trying building a generic Model Class. See:
class Basic_Model extends CI_MODEL {
function __construct() {
// Call the Model constructor
parent::__construct();
}
}
I want to extends all Models based on Basic_Model, like this:
class Pagina_Model extends Basic_Model {
function __construct() {
// Call the Model constructor
parent::__construct();
}
}
The problem is when i try to call "pagina_model" from a Controller a got the following error:
Fatal error: Class 'Basic_Model' not found in /var/www/myproject/application/models/pagina_model.php on line 12
If i use "basic_model" in controller everything works fine.
EDIT 1:
I created a file named MY_Basic_Model.php in "/application/core" and changed the class name to "MY_Basic_Model". But i got the error:
Fatal error: Class 'MY_Basic_Model' not found in /var/www/myproject/application/models/pagina_model.php on line 12
For this you have to create Core System Classes (this is also known as Method Overriding).
Create a file MY_Model.php in application/core/ directory which will extend the base CI_Model class:
<?php
class MY_Model extends CI_Model {
function __construct()
{
parent::__construct();
}
}
Now you can extend this in your models (../applicaton/models/):
<?php
class Pagina_Model extends MY_Model {
function __construct()
{
parent::__construct();
}
}
Few things to note here:
1) The class declaration must extend the parent class.
2) Your new class name and filename must be prefixed with MY_ (this item is configurable).
How to configure:
To set your own sub-class prefix, open your application/config/config.php file and look for this item:
$config['subclass_prefix'] = 'MY_';
Documentation:
https://ellislab.com/codeigniter/user-guide/general/core_classes.html
You can do it this way.
lets assume you have basic_model.php inside your model folder .
Now add the code for class Basic_Model that you have written
class Basic_Model extends CI_MODEL {
function __construct() {
// Call the Model constructor
parent::__construct();
}
}
Now make a pagina_model.php inside your model folder and add the code that you written. Just include the first line like bellow
<?php
require APPPATH.'/models/basic_model.php';//just add this line and keep rest
class Pagina_Model extends Basic_Model {
function __construct()
{
parent::__construct();
}
}
hope this will solve your problem
You can do this ... MY_ model is really good but should you wish a sub model to extend a different sub model you can always do:
require(APPPATH.'models/Other_model.php');
class New_model extends Other_Model {
In my instance Other_Model actually extends MY_model.
My CI version is CI2.3. I'm running this php code in my local host. I followed all the steps given there but I'm getting this error don't know why? and I changed Controller to CI_Controller. Hello world Program worked finely. This link code is not working. please need help!
you should extend model like this in codeIgniter
class Modelname extends CI_Model
{
function __construct()
{
parent::__construct();
}
}
Well actually the study guide is of old version of CI, where you used to extend your models from Model class as show in the guide. But now it has been changed. Now you have to extend it from CI_Model, same goes for Controller.
For controllers
class Employee_controller extends CI_Controller
{
//load the constructor
function __construct()
{
//inherit the parent constructor
parent::__construct();
}
}
and for models:
class Employee_model extends CI_Model
{
//load the constructor
function __construct()
{
//inherit the parent constructor
parent::__construct();
}
}
Use like this
<?php
class Employee_model extends CI_Model
{
//load the constructor
function __construct()
{
//inherit the parent constructor
parent::__construct();
}
}
You must create a model in the model folder like my_model.php
And create the class like
class My_model extends CI_Model
{
function __construct()
{
parent::__construct();
}
}
Remember the class and the file should be same.

I am new to codeigniter and I was trying my first app from the reference of this link
But I got the following error:
Fatal error: Class 'Controller' not found in /var/www/CodeIgniter/application/controllers/helloworld.php on line 2
Thi should be done like this
Class Mycontroller Extends CI_Controller
{
function __construct(){
parent::__construct();
}
//other functions
}
Class Mymodel Extends CI_Model
{
function __construct(){
parent::__construct();
}
//other functions
}
I'm trying out codeigniter for the first time on a MAMP deployment however I'm unable to load a model into a controller. The end result is always...
Unable to locate the model you have specified: second_model
Controller - welcome.php
class Welcome extends CI_Controller {
public function index()
{
$this->load->model('second_model');
$this->load->view('welcome_message');
}
}
Model - second_model.php
class Second_model extends Model {
public function __construct()
{
// model constructor
parent::__construct();
}
}
You should be extending CI_Model rather than Model
So:
class Second_model extends CI_Model {
public function __construct()
{
// model constructor
parent::__construct();
}
}
