Set value to created customer custom attribute in magento 2

This may help for you to save the custom attribute.

protected $_customerRepositoryInterface; public function __construct( \Magento\Customer\Api\CustomerRepositoryInterface $customerRepositoryInterface, \Magento\Customer\Model\CustomerFactory $customerFactory ) { $this->_customerRepositoryInterface = $customerRepositoryInterface; $this->_customerFactory = $customerFactory; } public function execute() { $customerId = 2; // Corresponding customer id $customer = $this->_customerFactory->create()->load($customerId)->getDataModel(); $customer->setCustomAttribute('custom_attribute_name', 'value'); $this->_customerRepositoryInterface->save($customer); } 

To save custom customer attribute

Code Tested in Magento v2.2.1 and it working.

namespace Vendor\Module\Controller\Index; use Magento\Customer\Model\Customer; use Magento\Customer\Model\ResourceModel\CustomerFactory as CustomerResourceFactory; use Magento\Customer\Model\Session as CustomerSession; use Magento\Framework\App\Action\Action; use Magento\Framework\App\Action\Context; /** * Class Index */ class Index extends Action { const CUSTOM_CUSTOMER_ATTR = 'xyz'; /** * @var CustomerResourceFactory */ protected $customerResourceFactory; /** * @var Customer */ protected $customerModel; /** * @var CustomerSession */ protected $customerSession; /** * Index constructor. * @param Context $context * @param CustomerResourceFactory $customerResourceFactory * @param Customer $customerModel * @param CustomerSession $customerSession */ public function __construct( Context $context, CustomerResourceFactory $customerResourceFactory, Customer $customerModel, CustomerSession $customerSession ) { parent::__construct($context); $this->customerResourceFactory = $customerResourceFactory; $this->customerModel = $customerModel; $this->customerSession = $customerSession; } /** * @return \Magento\Framework\App\ResponseInterface */ public function execute() { /* ********* Start : Important area : to save custom customer attribute value without losing session on refresh *********** */ if ($this->customerSession->isLoggedIn()) { $customAttributeValue = $this->getRequest()->getParam('custom_attribute'); // it just an example to pull value $customerId = $this->customerSession->getCustomer()->getId(); $customerNew = $this->customerModel->load($customerId); $customerData = $customerNew->getDataModel(); $customerData->setCustomAttribute(self::CUSTOM_CUSTOMER_ATTR, $customAttributeValue); $customerNew->updateData($customerData); $customerResource = $this->customerResourceFactory->create(); $customerResource->saveAttribute($customerNew, self::CUSTOM_CUSTOMER_ATTR); /* ********* End: Important area : to save custom customer attribute value without losing session on refresh *********** */ $this->messageManager->addSuccess(__('You are successfully save the data!!')); } return $this->_redirect('route/controller/action'); // it just an example for return } } 

@Developer Webile, Your code in question is invalid (few uses missed and other things). I added missing things. Here is Working code. P.S. Changed const name for better understanding/reading.

<?php namespace Vendor\ModuleName\Setup; use Magento\Framework\Setup\InstallDataInterface; use Magento\Framework\Setup\ModuleContextInterface; use Magento\Framework\Setup\ModuleDataSetupInterface; use Magento\Customer\Model\Customer; use Magento\Customer\Setup\CustomerSetupFactory as CustomerSetupFactory; use Magento\Eav\Model\Entity\Attribute\SetFactory as AttributeSetFactory; class InstallData implements InstallDataInterface { const NEW_ATTRIBUTE_NAME = 'new_attribute_name'; protected $customerSetupFactory; private $attributeSetFactory; public function __construct( CustomerSetupFactory $customerSetupFactory, AttributeSetFactory $attributeSetFactory ) { $this->customerSetupFactory = $customerSetupFactory; $this->attributeSetFactory = $attributeSetFactory; } public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context) { $setup->startSetup(); $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]); $customerEntity = $customerSetup->getEavConfig()->getEntityType('customer'); $attributeSetId = $customerEntity->getDefaultAttributeSetId(); $attributeSet = $this->attributeSetFactory->create(); $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId); $customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, self::NEW_ATTRIBUTE_NAME, [ 'type' => 'varchar', 'label' => 'Comment for new field', 'input' => 'image', "source" => '', 'required' => false, 'default' => '0', 'visible' => true, 'user_defined' => true, 'sort_order' => 210, 'position' => 210, ]); $document = $customerSetup->getEavConfig()->getAttribute(\Magento\Customer\Model\Customer::ENTITY, self::NEW_ATTRIBUTE_NAME) ->addData([ 'attribute_set_id' => $attributeSetId, 'attribute_group_id' => $attributeGroupId, 'used_in_forms' => ['adminhtml_customer', 'customer_account_create', 'customer_account_edit'], ]); $document->save(); $setup->endSetup(); } } 

Load your customer and try this:

$customer->setData('your_option_name', $yourOptionValue); $customer->save(); 

declare(strict_types=1); namespace Pranav\CustomerAttribute\Model; use Magento\Customer\Api\CustomerRepositoryInterface; use Magento\Customer\Model\CustomerFactory; class CustomerAttributeUpdate { /** * @var CustomerRepositoryInterface */ private $customerRepository; /** * @var CustomerFactory */ private $customerFactory; /** * @param CustomerRepositoryInterface $customerRepository */ public function __construct( CustomerRepositoryInterface $customerRepository, CustomerFactory $customerFactory ) { $this->customerRepository = $customerRepository; $this->customerFactory = $customerFactory; } public function execute($customer): string { $customerId = $customer->getEcommId(); $customerAdditional = $this->customerFactory->create()->load($customerId); //if you need to get customer custom attribute $registrationDate = $customerAdditional->getRegistrationDate(); $renewalDate = $customerAdditional->getRenewalDate(); $expiryDate = $customerAdditional->getExpiryDate(); $customerInterface->setCustomAttribute('registration_datetime', $registrationDate); $customerInterface->setCustomAttribute('renewal_date', $renewalDate); $customerInterface->setCustomAttribute('expiry_date', $expiryDate); $this->customerRepository->save($customerInterface); }
