ecart rules

I am trying to set up an online store for selling wine. We are wanting to only sell the wine in multiples of 6 and then subsequently provide a 15% discount to this total.

I understand that I need to write a rule which disallows purchases other than multiples of 6 but I don't know where to begin with writing rules for this? We would also need a note to come up letting the customer know that they haven't selected the correct quantity of wine, if they were to try and make a purchase that didn't fit this requirement.

Again, I don't know how to incorporate the 15% discount once the customer has met the above requirement?

I am completely new to the ecart system and online stores as a whole so sorry if I haven't provided enough information.

Any help would be appreciated!

in the add to cart button, set the quantity field to be update able from a select list, then populate the quantity select list with the desired quantity of 6,12, 18 etc.

does the 15% discount apply to all orders across the board?

Set this up on the discounts tab, use the trigger "Number of unique items in cart is > a value of 0

for the calcualtion use Based on multiple of cart subtotal
cart subtotal 'times' '0.15'

Sorry I didn't quite explain properly. We would like for customers to be able to pick from our range of wines so that they could buy say 3 of "wine1", 2 of "wine2" and then 1 of "wine3". So its the subtotal quantity which needs to be in multiples of 6 not each individual product.

But the calculation discount works well thanks!

ok, I see.

To start with, you can get the total quantity using the following code:

\$cartName->TotalColumn("Quantity")

where "cartName" is the name of your eCart object.

to determine if a number is a multiple by another number, you use division and look at the remainder, you can return the remainder using the modulus operator (%). the following code will check if the quantity is divisible by 6:

if(\$cartName->TotalColumn("Quantity") % 6 == "0")

i think the best way to do this for you site will be to use this if statement around the checkout button on the cart display page:

php:
``<?php if(\$cartName->TotalColumn("Quantity") % 6 == "0") { ?><checkout button here><?php } else { ?>the total quantity of your order must be a multiple of 6 before you can checkout<?php } ?>``

on the checkout pages, you can use the same if statement to redirect to the cart page if the quantity is not a multiple of 6, add this code just before the doctype tag on the checkout pages:

php:
``<?php if(\$cartName->TotalColumn("Quantity") % 6 != "0") {     header("Location: cart.php");}?>``
