class include

[eluser]xinq88[/eluser]
Hello everyone,

I'm new to codeigniter, but already have a pretty stupid question :down:.
So the following scenario happened: I have some class which depends on an other class.

So far I've written the following code:

Code:

/* this represents the way i use it in the present */
include_once('uur.php');
/**/

class UserInterface extends Controller {
    
    var $uur;
    var $data;
    var $partials;

    function UserInterface()
    {
        parent::Controller();
        
        $this->load->helper('url');
        $this->load->helper('form');
    }
    
    function index()
    {            
        /* this represents the way i use it in the present */
        $this->uur = new Uur();
        $this->content = $this->listUren();
        $this->content = $this->addUren();
        
    }
    
    function addUren()
    {
        // Set de title
        $this->data['title']  = 'uren toevoegen';
        
        // Set de view
        $this->partials = array('content'=>'uren_toevoegen');
        
        // Roep de functie toevoegen aan van de class Uur
        $this->uur->toevoegen('klanttest', '2008-08-05', '2');
        
        // Laad alle gegevens in de template 'main'
        $this->template->load('main', $this->partials, $this->data);
        
    }
}

Code:

class Uur extends Controller {
    
    var $data;
    
    function index()
    {    
        $this->load->database(); // Doesn't work
    }
    
    function toevoegen($klant, $datum, $tijd)
    {
        $data = array(
               'klant' => $klant,
               'datum' => $datum,
               'tijd' => $tijd
            );
            
        //$this->load->database();
        $this->db->insert('uren', $data);
    }
    
    function overzicht()
    {
        //Laad het database model, zodat database functies gebruikt kunnen worden
        //$this->load->database();
        return $this->db->get('uren');
    }
}

I don't think this is the 'codeigniter way' to include a class, because in this situation I can't seem to use the database helper etc. Also the constructor of the class Uur is not called when the following method is called: $this->uur = new Uur();

The output when I don't load the database helper in a specific function (like 'toevoegen') i get the following error while I have the database autoloaded:

Code:

Call to a member function get() on a non-object

I hope my poor English is understandable.

With kind regards,

Nick
