Order class notifiers

In /includes/classes/order.php the notifiers have been changed from using...

PHP Code:

---

$zco_notifier->notify(); 


---

...to...

PHP Code:

---

$this->notify(); 


---

This makes the code look cleaner but doesn't it make the notifiers unusable? My understanding is that to use these notifiers you would now have to attach the observers to the order object. However the order object isn't created until after all the auto-loaders have finished loading.

Am I missing something? Is there now a way to attach an observer to the order object, or even the order classs?

Regards,
Christian.

That's very intentional, as it now makes the notifiers in the order class actually work :blush:

Just to expand on the above.

When you do something like

$this->attach($this, array('NOTIFY_ORDER_CART_ADD_PRODUCT_LIST'));

you are not actually attaching to the class the notifier exists in, you are merely setting a callback to your observer for when that notifier happens.

It is only when the notifier happens that the class that the notifier exists in is passed to your observer classes update method.

Hi,

Thanks for the replies. Sorry if I'm being a bit stupid but I still don't quite understand. I'm used to attaching notifiers like...

PHP Code:

---

$_SESSION['cart']->attach($this, array('NOTIFIER_CART_ADD_CART_END'));
$zco_notifier->attach($this, array('NOTIFY_HEADER_END_CHECKOUT_CONFIRMATION')); 


---

How would I now do a similar thing with the notifiers in the order class code?

Do I just create my own order object and use that to attach the notifiers?

Many thanks,
Christian.

Example:
In the order class, there's a notifier point NOTIFY_ORDER_AFTER_SEND_ORDER_EMAIL.
So, to hook it, I simply use:

Code:

---

    $this->attach($this, array('NOTIFY_ORDER_AFTER_SEND_ORDER_EMAIL'));

---

You'll use the $this->attach() method to hook notifier points that are inside a class.
You'll use the $zco_notifier->attach() method to hook notifier points that are NOT inside a class.

Note also,

Attaching to the cart class is slightly different because of the fact that the instantiated object is stored in the session.

Thank you both for your help. I think it was the cart class example that was confusing me. I assumed the other observers had to be attached to specific instantiated objects.

Many thanks,
Christian.
