How to set customer custom attribute in magento 2?

Question

I have created some custom attributes for a customer in magento2 community edition,

I have used below code to set in my custom code

use Magento\Customer\Api\AccountManagementInterface;
use Magento\Framework\App\Action\Context;
use Magento\Customer\Api\AccountManagementInterface;
use Magento\Customer\Model\CustomerExtractor;

class CreateCustomer extends \Magento\Customer\Controller\AbstractAccount
 {
  protected $customerRepository;
  protected $accountManagement;
  protected $customerExtractor;

  public function __construct(
    Context $context,
    AccountManagementInterface $accountManagement,
    CustomerExtractor $customerExtractor,
  ) {
    $this->accountManagement = $accountManagement;
    $this->customerExtractor = $customerExtractor;
   parent::__construct($context);
}
  public function execute()
{
  try {
       $customer = $this->customerExtractor->extract('customer_account_create', $this->_request);
        $password = $this->getRequest()->getParam('password');
        $confirmation = $this->getRequest()->getParam('password_confirmation');

        $customer = $this->accountManagement
            ->createAccount($customer, $password, $redirectUrl);

         $this->customerRepository = ObjectManager::getInstance()->get(
            \Magento\Customer\Api\CustomerRepositoryInterface::class
        );  

        $customer->setCustomAttribute('is_checked', 0);
        $this->customerRepository->save($customer);    
 }catch (StateException $e) {
      print_r($e->getMessage());
   }
  }
}
 $customer->setCustomAttribute('is_checked', 0);

This attribute is a custom attribute and I have set default_value as 0, but it is not saving on creating a customer. I can't see any value in the table for any of the customers.

This is not storing in the table. What is the reason please anyone helps me with this.

Here is the screenshot for the attribute in the table

attribute_code is customer_activated.

Answer 1

Try that code to save custom attribute of customer

$customerRepository = $this->objectManager->get('Magento\Customer\Api\CustomerRepositoryInterface');
$customerId = $params['customerId'];
$customer = $customerRepository->getById($customerId);
 
$customer->setCustomAttribute("is_checked",'0');
 
$customerRepository->save($customer);

Answer 2

Use setData to save the values, as try like this

$customer->setData(array('is_checked'=>0));

And use the try catch method for the save function to find possible exceptions.

Also please post the custom attribute creation code
