How to load two models in the same controller with CodeIgniter?

Question

I've been searching on Internet and on stackoverflow, but i didn't find a solution, or it wasn't the same problem.

I need to load two models in the same controller, and in the same function. One is "model_membre" and the other "model_annonce". It's the name of the class, the file, and the object.

Individually, they work very good, i can access to properties and methods, but when I'm loading the two models, I can't access to the second, regardless of how I load it (autoload, $this->load->model('model_name'), $this->load->model('model_name', 'object_name')).

I simplified to a "test" controller, to see if it was not another part of my code that made the problem :

    public function index()
{
    $this->load->model('model_membre', 'membre');
    $this->load->model('model_annonce', 'annonce');
    $liste = $this->annonce->listerEspeces();
    $membre = $this->membre->obtenirMembre(1);
}

I tried to changer the order, and the 2nd loaded never works. I get this message :

A PHP Error was encountered Severity: Notice Message: Undefined property: Test::$annonce Filename: controllers/test.php Line Number: 15

Fatal error: Call to a member function listerEspeces() on a non-object in /homez.604/animalix/beta/application/controllers/test.php on line 15

Are you sure that your model is not stored in subfolder for example models->subfolder->your_model — Ahmed Gaber

No, both are stored in /application/models/model_name.php :/ If not, they would not be loaded and work individually — OwNAkS

What happens when you ONLY load model_annonce ? Does it work properly then? — ashiina

Have you tried without the second param in load->model and calling $this->model_annonce->listerEspeces()? — Steven Lu

Also, if you're using __construct() in any of your models, remember to add parent::__construct() in your __construct() method which may be causing this error. — Steven Lu

Please try the following way...

 public function index()
{
    $this->load->model(array('membre','annonce'));
    $liste = $this->annonce->listerEspeces();
    $membre = $this->membre->obtenirMembre(1);
}

I tried the following without success, the same error, call to a member function listerEspeces() on a non-object. [code]public function index() { $this->load->model(array('model_membre', 'model_annonce')); $liste = $this->model_annonce->listerEspeces(); $membre = $this->model_membre->obtenirMembre(1); }[/code]

@OwNAkS - then your error might be coming from another part of your code.

@mamdouhalramadan It is not possible because I made a controller just for testing, empty, with just the constructor, and the function written above. I dont have any models loaded in my autoload.php.

then try loading both models from autoload :)

The models should extend CI_Model and not CI_Controller! This was the source of the problem.
