I have a customer ID and I want to get first name and last name of that customer. Any solution?

The Best idea to use repository interface for getting customer data Magento 2.2..

MagentoCustomerApiCustomerRepositoryInterface

Use function getById($customerId)

Inject that class on __construct function then use this class of getting customer object

public function __construct(
MagentoCustomerApiCustomerRepositoryInterface $customerRepository 
)
 $this->customerRepository = $customerRepository;

public function getCustomerDetails()

 $customer = $this->customerRepository->getById($customerId);
 if($customer->getId())
 echo $customer->getFirstname();
 echo $customer->getLastname();

 

You want to use Object Manager then this

$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$customerRepository = $objectManager->create(MagentoCustomerApiCustomerRepositoryInterface::class);
$customer = $customerRepository->getById(CUSTOMER_ID);
if($customer->getId())
 echo $customer->getFirstname();
 echo $customer->getLastname();

Use below code

$customerID = 10; // your customer-id
$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$customerObj = $objectManager->create('MagentoCustomerModelCustomer')
 ->load($customerID);
$customerFirstName = $customerObj->getFirstName();
$customerLastName = $customerObj->getLastName();

By factory method:

protected $_customers;

public function __construct(
 ...
 MagentoCustomerModelCustomer $customers
 ...
) 
 ...
 $this->_customers = $customers;
 ...


public function getCustomer($customerId)

 //Get customer by customerID
 $customer = $this->_customers->load($customerId);
 echo $customer->getFirstName(); //Print Customer First Name
 echo $customer->getLastName(); //Print Customer Last Name


public function getCollection()

 //Get customer collection
 return $this->_customers->getCollection();

Note: It is not recommended to use objectManager directly.

You can achieve like this also:

 <?php 



namespace MasteringItdesireBlockIndex;

class Index extends MagentoFrameworkViewElementTemplate


 protected $_customer;

 public function __construct(
 MagentoCustomerModelCustomer $customer,
 MagentoBackendBlockTemplateContext $context
 )
 
 $this->_customer = $customer;
 parent::__construct($context);
 

 public function getCustomer()
 
 $customerId = '189'; //You customer ID
 $customer = $this->_customer->getCollection()->addAttributeToFilter('entity_id', array('eq' => $customerId));
 echo "Customer Name:".$customer->getFirstName();
 echo "Customer Name:".$customer->getLastName();
 

Hope, This will help you some extend.
