Question

I have a model class ModelHome that is a child of Model ie:

class ModelHome extends Model

Model is a variable of the Controller class ie:

class Controller {

    public $model;

    public function __construct () {
        $this->model = new Model;
    }
}

Is it possible to access a method within the Controller class from within a method inside the ModelHome class?

I’ve tried parent:: and calling the class by name ie Controller::method but I can’t seem to find the right scope to access the method I need.

Thanks.

First of all, you must have an instance of ModelHome. If you make an instance of Model, that has not automatically been extended by ModelHome just because ModelHome exists. So, i guess your Controller::__construct() should be:

public function __construct () {
    $this->model = new ModelHome;
}

However, your ModelHome does not know about your Controller class/instance. You could make a __construct in ModelHome that takes a parameter with a link to the controller. Like this:

class ModelHome extends Model {

    public $controller;

    public function __construct ($controller) {
        $this->controller = $controller;
    }
}

class Controller {

    public $model;

    public function __construct () {
        $this->model = new ModelHome($this);
    }
}

Now, your ModelHome knows about the controller by using $this->controller
