data missing after onAfterOrderUpdate

Hi,

In onAfterOrderUpdate, the data you have in $element is the order that is being modified by the save.
If the data is missing it just means that the code calling the save doesn't want to update that data.
For example, if a payment plugin automatically changes the status of the order after the payment, it only provides the order_id and the new order_status (HikaShop will add automatically the order_modified, and maybe other elements like the order_invoice_id, order_invoice_number if the invoice number is being generated).

So in onAfterOrderUpdate, if you want to use information about an order, you need to do two things:
- look directly in $element and if it's there, use it
- look in $element->old . There, you have all the data of the order from before the save.
So for example, suppose you want to check the order_type to only take into account main orders (and not sub orders of HikaMarket), you would need to do it like this:

public function onAfterOrderUpdate(&$element, &$send_email) {
 // only take into account main orders
 $type = $element->old->order_type;
 if(!empty($element->order_type))
  $type = $element->order_type;
 if($type != 'sale')
  return;

 // process the order changes
}

Hi,

Mmm, I already answered all the questions of your new message in my previous message, so I'm not sure what to say.

In $element->old you will get all the data of the order before the save, always.
In $element you will get the changing data of the order.

So for example, if you want to get the language of the order, you can do it like this:
$lang = $element->old->order_lang;
if(!empty($element->order_lang))
$lang = $element->order_lang;

That way, in $lang you'll get the new order_lang if the lang is being changed by the save, or the order_lang from the database if it's not.
So onAfterOrderUpdate does provide all the data of the order, and you don't need to do anything to get the data not in $element. Just look in $element->old

The fact that you might get all the order data in $element is some cases is just luck based on how the person who wrote the code handled the saving. In a plugin, you should assume that $element doesn't have everything, and you need to use $element->old when what you want is missing in $element
