I am currently implementing a Paypal Express Checkout and I have multiple items going into an order. These items are successfully going into Paypal and being shown individually on the invoice. Once the customer returns to my website the client is returned through a processing page which puts the items into a database, but instead of the individual items with their individual prices being listed I am only getting one item and the total price.
if($_POST) //Post Data received from product list page.
{
//Other important variables like tax, shipping cost
$TotalTaxAmount = 0.00; //Sum of tax for all items in this order.
$HandalingCost = 0.00; //Handling cost for this order.
$InsuranceCost = 0.00; //shipping insurance cost for this order.
$ShippinDiscount = 0.00; //Shipping discount for this order. Specify this as negative number.
$ShippinCost = 0.00; //Although you may change the value later, try to pass in a shipping amount that is reasonably accurate.
//we need 4 variables from product page Item Name, Item Price, Item Number and Item Quantity.
//Please Note : People can manipulate hidden field amounts in form,
//In practical world you must fetch actual price from database using item id.
//eg : $ItemPrice = $mysqli->query("SELECT item_price FROM products WHERE id = Product_Number");
