Hi...some advice please...

Hi there,

I'm busy with some slight modifications...

Can anyone tell me what the following lines of code are used for?
in catalog/includes/classes/order.php

Line 917:

  // update totals counters
  $this->total_weight += ($this->products[$i]['qty'] * $this->products[$i]['weight']);
  $this->total_tax += zen_calculate_tax($total_products_price * $this->products[$i]['qty'], $products_tax);
  $this->total_cost += $total_products_price;

  $this->notify('NOTIFY_ORDER_PROCESSING_ONE_TIME_CHARGES_BEGIN', $i);

I used Deveopers Toolkit to see if I can find any references to any of these variables/defines...but I can't pick up anything...

Any help would be much loved thank you :)

These variables are used to total up each of the respective values: weight, tax, total cost, and then the "constant" is actually a notifier that is used to observe the data and take action if so desired.

As far as finding these things using the DTK, you would want to search on things like: total_weight, total_tax, or total_cost...

The constant is not likely to be found elsewhere in default ZC code because the code is written to operate mostly by direct flow.

Hi mc12345678,

ah I see now...thanks so much!

Actually, it's not a constant. It's just a string. We happen to have embraced the use of uppercase letters when naming notifier hooks; but they're not actually constants even though they look like them.

Indeed, you can tell they are not constants since they are quoted. They're just string values.
