Discount Rule Help

I have a discount rule for buy 6 and get the cheapest free that looks like this:

//eCart Rule

function WAEC_eCart1_Buyany6TTProductsandgettheCheapest1Free()  {

  $totalDiscount = 0;

  if (true && ((sizeof($this->Items) > 0) && (( ((($this->ConditionalTotal("Quantity", "TypeID", "1")) + ($this->ConditionalTotal("Quantity", "TypeID", "2")) + ($this->ConditionalTotal("Quantity", "TypeID", "3")) + ($this->ConditionalTotal("Quantity", "TypeID", "4")) + ($this->ConditionalTotal("Quantity", "TypeID", "5")) + ($this->ConditionalTotal("Quantity", "TypeID", "7")) + ($this->ConditionalTotal("Quantity", "TypeID", "8")) + ($this->ConditionalTotal("Quantity", "TypeID", "9")) + ($this->ConditionalTotal("Quantity", "TypeID", "10")) + ($this->ConditionalTotal("Quantity", "TypeID", "12")) + ($this->ConditionalTotal("Quantity", "TypeID", "16")) + ($this->ConditionalTotal("Quantity", "TypeID", "17")) + ($this->ConditionalTotal("Quantity", "TypeID", "18")) + ($this->ConditionalTotal("Quantity", "TypeID", "19"))) >= 6) )))) {

    $totalDiscount += $_SESSION['tt6get1'];//Result

  }

  return WA_eCart_FormatNumber($totalDiscount, $this->ForceDecimalsC, $this->DecimalPlacesC);

}

//eCart Rule

where I am checking the quantity of the Product Type ID column in the cart which works great if a single line total of the Product Type ID is greater than or equal to 6 BUT I would like it to work if the sum of the Product Type ID line totals is greater than or equal to 6.

How can I make a rule that can do this please.

Hi Dave,

I must be a bit slow today (not interpreting the question)

I copied the rule onto one of my test stores, and reduced the item types to 1, 2 or 3, (to fit in with my own data)
if i have a total of 6 items from any combination of these itemtypes, the rule seems to trigger.

i assume that isn't what you want to do.

That is exactly what I want to do but for some reason it isn't working for me, I wonder if the order of discounts makes a difference ?

it shouldn't make any difference, but i just changed my order to 2,1,3 and it still works.

i presume you checked the obvious stuff, like all the ItemTypes have the expected Id's and you have copied the eCart folder to the server ?

;-)

one thing I always when I have rule that is not behaving as expected is create a second cart display page on this page, I set the display manager to show all columns from the cart, seeing all the information stored in the cart often helps me find the cause often problem.

Good advice Jason, I will do just that

ok I have uploaded the new test files to my development server, if I add 6 of one item to the cart the discount rule is triggered correctly

if I add two quantities of the same product type (the number after the product type is the ID that I am checking for) then the discount rule doesn't get triggered

If I add two quantities of different product types (both covered by the rule) the discount rule still isn't triggered

I am obviously missing something simple, but what ?

can you send a copy of the cart include file so i can try testing on my end.

Jason,

here you go, thanks

in my test i created two add to cart buttons, one set the TypeID to 1, the other set the TypeID to 2, I can add three of one item and 3 of the other and the discount comes through. It is working in my tests.

did you create the cart page to show all columns that I suggested? can you send a link to that cart page?
