Magento – Checkout: Mixed cart, split order and split payment

checkoutorder-splittingpayment

Trying to workout the best approach to checkout(mixed cart) a specific product type with payment1 and all other product types with payment[2].

I guess splitting the order will be one part, do you have any clues as to how I would then process split(1) with payment(1) and split(2) with payment(2) ?

My initial thoughts were to somehow create a product set that doesn't have a price and to then mask the cart total. Couldn't find anything on approaching that way though.

Splitting the order is not really necessary since the payment applies more to the invoice than the order itself. Check out this answer on Stackoverflow on how to make a partial invoice. If you have 2 payment methods that would result in 2 invoices.

From the checkout point of view it depends on what kind of payment method you're using. The real issue would come from 2 payment methods that are both handled by 3th parties thus needing a redirect. But if your 'special product' should be paid using a banktransfer for example create an extension that first makes an invoice out of that product adding bank transfer as payment method and then sending of the rest of the amount to pay to, for example, a Credit Card gateway

It is doable quite easily with a rewrite of the checkout/type_onepage model.
In that class override the saveOrder() method as follows:

public function saveOrder()
{
    $quote = $this->getQuote();

    // First build an array with the items split by vendor
    $sortedItems = array();
    foreach ($quote->getAllItems() as $item) {
        $vendor = $item->getProduct()->getVendor(); // <- whatever you need
        if (! isset($sortedItems[$vendor])) {
            $sortedItems[$vendor] = $item;
        }
    }
    foreach ($sortedItems as $vendor => $items) {
        // Empty quote
        foreach ($quote->getAllItems() as $item) {
            $quote->getItemsCollection()->removeItemByKey($item->getId());
        }
        foreach ($items as $item) {
            $quote->addItem($item);
        }
        // Update totals for vendor
        $quote->setTotalsCollectedFlag(false)->collectTotals();

        // Delegate to parent method to place an order for each vendor
        parent::saveOrder();
    }
    return $this;
}

But be aware that in Magento a payment is associated with an invoice, and each invoice is associated with an order.

In consequence this means that as soon as you have multiple orders, you will also have split the payments. So this is only feasible if the payment method doesn't require user interaction during the payment.

UPDATE: The orginal answer delegated to parent::save() which had to be parent:saveOrder(). It is fixed in the example code now.
