Magento multiple order dalam satu checkout atau pemisahan pesanan

Produk toko dipasok dari vendor yang berbeda. Anda harus membuat beberapa pesanan untuk setiap vendor berdasarkan produknya di troli selama satu checkout. Apakah ada ekstensi untuk menyelesaikan tugas ini atau haruskah saya mulai mengembangkan modul checkout kustom. Bagaimana dengan hot point untuk menciptakan visi perluasan seperti itu dari pengembang Magento yang berpengalaman? Bisakah Anda jelaskan saya arsitektur aliran checkout singkat yang ramah Magento (mungkin level kode)? Terima kasih banyak lagi!

Ini bisa dilakukan dengan cukup mudah dengan menulis ulang checkout/type_onepagemodel.
Di kelas itu timpa saveOrder()metode sebagai berikut:

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;
}

Namun ketahuilah bahwa di Magento pembayaran dikaitkan dengan faktur, dan setiap faktur dikaitkan dengan pesanan.

Karena itu ini berarti bahwa segera setelah Anda memiliki banyak pesanan, Anda juga akan membagi pembayaran . Jadi ini hanya layak jika metode pembayaran tidak memerlukan interaksi pengguna selama pembayaran.

UPDATE : Jawaban asli yang didelegasikan parent::save()harus parent:saveOrder(). Itu diperbaiki dalam kode contoh sekarang.

Berikut ini diuji dalam CE ver 1.9.0.x

PENTING Anda perlu menyesuaikan metode pembayaran untuk mengambil grand total dari penawaran.
