Shop Discount

[Kyttias]

Nvm, got it work finally. -o-

If you send another value, for a discount, through the buy form, you can access it in class_stockitem.php in the getcost function. But this is just to fix the display on the confirmation screen.

PHP Code:

 public function getcost($salestax = 0, $quantity = ""){
      // Get the total cost of this stock item
      $mysidia = Registry::get("mysidia");
      if(empty($quantity)) $quantity = $mysidia->input->post("quantity");
      $discount = $mysidia->input->post("discount");
      $costbeforediscount = $this->price*$quantity*(1+$salestax/100);
    $cost = $costbeforediscount * ((100-$discount) / 100);
      return $cost;
  } 


To show users a discounted price, you'll need to do this in the display function of class_itemshop.php -

PHP Code:

# A 5% discount:
$discount = 5;
$price = $item->price * ((100-$discount) / 100); 


And replace the $item->price where it would show the item's price when rendering the item to just $price.

To actually make a discount percentage go through in terms of calculations you'll have to modify the purchase() function in class_itemshop.php -

PHP Code:

$cost = $item->getcost($this->salestax, $item->quantity) * ((100-$discount) / 100); 


Sorry for the vague ramblings, it's actually the first part I had trouble with (getting the proper amount to show on the confirmation screen), but maybe someone will have gotten something out of rest of this.
