I am using a shipping modifier to add shipping costs to the total of an order. The shipping appears ok on the checkout page, but when the user goes to pay in paypal the shipping is not included in the order. Does anyone know of a solution/what could be causing this please?

I am running the latest release of silverstripe (2.3.0) and a trunk version of e-commerce.

Thanks.

Just wondering if anyone else has found a solution to this problem. I remember seeing a similar post before but can't find it in the forum.

Thanks.

Did you installed ecommerce module with simple shipping or weight based shipping?

I've copied the code for the modifier I'm using below. The costs are displayed correctly at the checkout before being redirected to paypal, but are not sent with the total to paypal. Any help is very welcome.

<?php

/**
* @package ecommerce
*/

/**
* DeliverychargeModifier is based on the default shipping calculation scheme.
* It lets you set shipping costs by quantity
*/
class DeliveryChargeModifier extends OrderModifier {
      protected static $is_chargable = true;
      static $default_charge = 0.7;

      /*static $charges_by_quantity = array( 1 => 0.7, 4 => 1.5, 7 => 3);*/
	  static $charges_by_quantity = array( 1 => 1.48, 2 => 1.78, 3 => 5.90, 4 => 7.90, 5 => 9.75, 8 => 11.25, 9 => 16.0);

      static function set_charges($charge) {
             self::$default_charge = $charge;
      }

      function LiveAmount() {
               $o = ShoppingCart::current_order();
               $orderItems = $o->Items();

               // Calculate the total quantity of the order
               if($orderItems){
               foreach($orderItems as $orderItem){
                    $totalQuantity += $orderItem->quantity;
                    }
               }

               //calculate packaging cost
               foreach(self::$charges_by_quantity as $quan => $price){
                    if ($totalQuantity >= $quan){
                    $totalCost = $price;// * $totalQuantity;
                    }
               }
               
               return $totalCost;
	       }


          // Display Functions

	function TableTitle() {
		return "Postage and packaging";
	}
	function CartTitle() {return 'Postage and packaging: ';}
}

I found this which solved my problem hope it helps. The paypal module does not seem to copy over the modifiers this is a hack to fix that.

Thanks for the suggestion. I tried the fix mentioned in the other post but shipping costs are still not being transferred with the total to paypal. Here's my paypalpayment code, could you check I've put the modifier fix in the correct place please? Thanks for your help.

Actually, I have just tested the fix with the SimpleShippingModifier instead of my own modifier and it is working ok. Thanks for your help hive.net.au, I just need to sort out my modifier now!
