如何在magento2 中以编程方式创建订单？

Magento 2 您可以通过简单的编码以编程方式创建订单。

您需要为订单创建自定义报价，并在此基础上通过简单的代码将报价转换为 Magento 2 中的订单。

从模板文件创建订单信息到帮助文件。

<?php
$orderInfo =[
    'currency_id'  => 'USD',
    'email'        => 'rakesh.jesadiya@testttttttt.com', //customer email id
    'address' =>[
        'firstname'    => 'Rakesh',
        'lastname'     => 'Testname',
        'prefix' => '',
        'suffix' => '',
        'street' => 'B1 Abcd street',
        'city' => 'Los Angeles',
        'country_id' => 'US',
        'region' => 'California',
        'region_id' => '12', // State region id
        'postcode' => '45454',
        'telephone' => '1234512345',
        'fax' => '12345',
        'save_in_address_book' => 1
    ],
    'items'=>
        [
            ['product_id'=>'1','qty'=>1], //simple product
            ['product_id'=>'67','qty'=>2,'super_attribute' => array(93=>52,142=>167)] //configurable product, pass super_attribte for configurable product
        ]
];
$helper = $this->helper('Rbj\Training\Helper\Data');
$orderData = $helper->createOrder($orderInfo);

?>

在上述订单信息中，我们获取客户基本详细信息和商品信息。
我们采用了一个简单且可配置的产品项目。对于可配置产品，我们需要传递super_attribute数组值。出于测试目的，我采用了 Magento Sample 数据可配置和简单的产品 ID。

For Configurable, 93 is Color attribute id where 52 is Gray option id.
142 is size attribute id where 167 is for XS size option id, you need to pass the dynamic value for a configurable product.

Create helper file,

Let’s say Data.php file location at, app/code/Rbj/Training/Helper/Data.php

<?php
/**
 * ExtendedRma Helper
 */
namespace Rbj\Training\Helper;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{

    public function __construct(
        \Magento\Framework\App\Helper\Context $context,
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Customer\Model\CustomerFactory $customerFactory,
        \Magento\Catalog\Api\ProductRepositoryInterface $productRepository,
        \Magento\Customer\Api\CustomerRepositoryInterface $customerRepository,
        \Magento\Quote\Model\QuoteFactory $quote,
        \Magento\Quote\Model\QuoteManagement $quoteManagement,
        \Magento\Sales\Model\Order\Email\Sender\OrderSender $orderSender

    ) {
        $this->storeManager = $storeManager;
        $this->customerFactory = $customerFactory;
        $this->productRepository = $productRepository;
        $this->customerRepository = $customerRepository;
        $this->quote = $quote;
        $this->quoteManagement = $quoteManagement;
        $this->orderSender = $orderSender;
        parent::__construct($context);
    }
    /*
    * create order programmatically
    */
    public function createOrder($orderInfo) {
        $store = $this->storeManager->getStore();
        $storeId = $store->getStoreId();
        $websiteId = $this->storeManager->getStore()->getWebsiteId();
        $customer = $this->customerFactory->create();
        $customer->setWebsiteId($websiteId);
        $customer->loadByEmail($orderInfo['email']);// load customet by email address
        if(!$customer->getId()){
            //For guest customer create new cusotmer
            $customer->setWebsiteId($websiteId)
                    ->setStore($store)
                    ->setFirstname($orderInfo['address']['firstname'])
                    ->setLastname($orderInfo['address']['lastname'])
                    ->setEmail($orderInfo['email'])
                    ->setPassword($orderInfo['email']);
            $customer->save();
        }
        $quote=$this->quote->create(); //Create object of quote
        $quote->setStore($store); //set store for our quote
        /* for registered customer */
        $customer= $this->customerRepository->getById($customer->getId());
        $quote->setCurrency();
        $quote->assignCustomer($customer); //Assign quote to customer

        //add items in quote
        foreach($orderInfo['items'] as $item){
            $product=$this->productRepository->getById($item['product_id']);
            if(!empty($item['super_attribute']) ) {
                /* for configurable product */
                $buyRequest = new \Magento\Framework\DataObject($item);
                $quote->addProduct($product,$buyRequest);
            } else {
                /* for simple product */
                $quote->addProduct($product,intval($item['qty']));
            }
        }

        //Set Billing and shipping Address to quote
        $quote->getBillingAddress()->addData($orderInfo['address']);
        $quote->getShippingAddress()->addData($orderInfo['address']);

        // set shipping method
        $shippingAddress=$quote->getShippingAddress();
        $shippingAddress->setCollectShippingRates(true)
                        ->collectShippingRates()
                        ->setShippingMethod('flatrate_flatrate'); //shipping method, please verify flat rate shipping must be enable
        $quote->setPaymentMethod('checkmo'); //payment method, please verify checkmo must be enable from admin
        $quote->setInventoryProcessed(false); //decrease item stock equal to qty
        $quote->save(); //quote save 
        // Set Sales Order Payment, We have taken check/money order
        $quote->getPayment()->importData(['method' => 'checkmo']);
 
        // Collect Quote Totals & Save
        $quote->collectTotals()->save();
        // Create Order From Quote Object
        $order = $this->quoteManagement->submit($quote);
        /* for send order email to customer email id */
        $this->orderSender->send($order);
        /* get order real id from order */
        $orderId = $order->getIncrementId();
        if($orderId){
            $result['success']= $orderId;
        }else{
            $result=['error'=>true,'msg'=>'Error occurs for Order placed'];
        }
        return $result;
    }

You got a result as array for success order place, Array ( [success] => ‘OrderId’ )
