Magento 2 - Create customer programmatically from order

Question

What is most optimized way to create customer programmatically from order ?

As i need to create customer for a guest user, what will be the better way of implementing it ?

Answer 1

Please try the below reference code(Convert guest customer to regular customer on successful order place in magento 2). You can run that code by creating a custom script in the Magento root

 $collection     = $this->filter->getCollection($this->collectionFactory->create());
    $collectionSize = $collection->getSize();
    $count          = 0;
    /** @var $order \Magento\Sales\Model\Order */

    foreach ($collection as $order) {
        $websiteId  = $order->getStore()->getWebsiteId();
        $storeId    = $order->getStore()->getId();

        $customerData = $this->objectCopyService->copyFieldsetToTarget(
                'order_address',
                'to_customer',
                $order->getBillingAddress(),
                []
                );



        $addresses = $order->getAddresses();
        foreach ($addresses as $address) {
            $addressData = $this->objectCopyService->copyFieldsetToTarget(
                    'order_address',
                    'to_customer_address',
                    $address,
                    []
                    );

            /** @var \Magento\Customer\Api\Data\AddressInterface $customerAddress */
            $customerAddress = $this->addressFactory->create(['data' => $addressData]);
            switch ($address->getAddressType()) {
                case QuoteAddress::ADDRESS_TYPE_BILLING:
                    $customerAddress->setIsDefaultBilling(true);
                    break;
                case QuoteAddress::ADDRESS_TYPE_SHIPPING:
                    $customerAddress->setIsDefaultShipping(true);
                    break;
            }

            if (is_string($address->getRegion())) {
                /** @var \Magento\Customer\Api\Data\RegionInterface $region */
                $region = $this->regionFactory->create();
                $region->setRegion($address->getRegion());
                $region->setRegionCode($address->getRegionCode());
                $region->setRegionId($address->getRegionId());
                $customerAddress->setRegion($region);
            }
            $customerData['addresses'][] = $customerAddress;
        }
        $account    = $this->createUser($customerData, $websiteId, $storeId, (int)$this->getRequest()->getParam('group'), $count);

        $order
        ->setCustomerId($account->getId())
        ->setData('customer_group_id', $account->getGroupId())
        ->setData('customer_is_guest', 0)
        ->setData('customer_firstname', $account->getFirstname())
        ->setData('customer_lastname', $account->getLastname());

        $this->orderRepository->save($order);

    }
