Magento associate customer with order after an placed order

My custom module observes the sales_order_place_after event, and creates a customer and associates the customer with the order by setting customerId for the order.

What works?

  • Order is placed
  • Customer is created
  • The customerId is updated in the order database

What doesn’t work?

  • The customerId is instantly set back to NULL by another script

How can I find out what script updates the customerId to NULL again, after my observer is done running?

    You should change event to sales_model_service_quote_submit_success

    Example Code (Magento 2 Version): events.xml

    <event name="sales_model_service_quote_submit_success">
        <observer name="quote_submit_success_observer" instance="NamespaceModuleNameObserverGenerateObserver" />
    </event>

    GenerateObserver.php

     ...
 public function execute(MagentoFrameworkEventObserver $observer)
 {
    /** @var MagentoSalesModelOrder $order */
        $order = $observer->getEvent()->getData('order');

    // Ensure customer is registered
    $this->registerCustomer($order);
    $order->getResource()->save($order);
 }

protected function registerCustomer(
    MagentoSalesApiDataOrderInterface $order
) {
    /** @var MagentoSalesModelOrder $order */

    if ($order->getCustomerId() === null) {
        // Load customer by email, create if not exists.
        try {
            $customerData = $this->customerRepository->get($order->getCustomerEmail());
        } catch (MagentoFrameworkExceptionNoSuchEntityException $e) {
            $customerData = $this->orderCustomerManager->create($order->getId());
        }

        $order->setCustomerId($customerData->getId());
    }

    return $this;
}

    I had the same problem – my assumption was that calling the save method on the order triggered whatever was listening to the sales_order_save_before/after events, one of which was setting the customer ID back to null. I worked around this by saving only the attributes I wanted, rather than triggering a save on the entire order:

    $order
    ->setCustomerId($customer->getId())
    ->setCustomerIsGuest(0)
    ->setCustomerGroupId($customer->getGroupId());

$order->getResource()
    ->saveAttribute($order, 'customer_id'      )
    ->saveAttribute($order, 'customer_is_guest')
    ->saveAttribute($order, 'customer_group_id');

    This allowed me to successfully associate a customer with the order in Magento EE 1.14.3.10 using the sales_model_service_quote_submit_success event.
