I want to update the firstname of a customer like this :

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$customerFactory = $objectManager->create('\Magento\Customer\Model\CustomerFactory');

$customer = $objectManager->create('Magento\Customer\Model\Customer')->setWebsiteId(1)->loadByEmail('[email protected]');

try {

But the name of the customer doesn't change

  • Isn't your 2nd line conflicting with the 3rd one? Sep 27, 2016 at 14:08

I'm not entirely sure what's wrong with your code but here's how I did it a few weeks ago using service contracts. Also please try to avoid using the ObjectManager directly

protected $_customerRepoInterface;

public function __construct(
    \Magento\Customer\Api\CustomerRepositoryInterface $customerRepoInterface
) {
    $this->_customerRepoInterface = $customerRepoInterface;

Then in your code you can do:

// Second parameter is the website id
$customer = $this->_customerRepoInterface->get('[email protected]', 1);
// Update
  • Hey dude this looks fine, my code already worked 50% just didn't mention to reindex... The customers name changed, but i have also some spezial customer field eg: textfield called "cusattr123" i want to fill it with $customer->setCusattr123('value'); but this didn't work.

create a controller

   protected $_customerRepositoryInterface;

   public function __construct(
    \Magento\Framework\App\Action\Context $context,
    \Magento\Framework\View\Result\PageFactory $resultPageFactory,
    \Magento\Customer\Api\CustomerRepositoryInterface $customerRepositoryInterface
  ) {
    $this->resultPageFactory = $resultPageFactory;
    $this->_customerRepositoryInterface = customerRepositoryInterface;

Now execute function here reward_barcode is custom attribute:

 public function execute()
     $customerId = 2;
     if ($customerId) {

            $customer = $this->_customerRepositoryInterface->getById($customerId);
            $customer->setCustomAttribute('reward_barcode', $barcode);

   $this->messageManager->addSuccess( __('Your membership successfully updated.') );
