how to change customer session data in Magento 2?

Question

after customer login, I want to change some of the session params like customer name. I do like this

$this->_customerSession->getCustomer()->setName("ddddddd");

also i tried this

$this->_customerSession->setName("ddddddd");

but it does not work.so how I can change the customer basic data, also how Magento handles session data? I think after every request the Magento set session data from database...hmmm am I going wrong? is there anyone to talk about this?

I want to change the customer name and this change should be staying until the customer is login ...lets to review my problem ... I have a customer that can have sub customer (or may should I say, members) when a sub customer want to login with his/her username and password I check them and if they were correct I get parent customer and set it login but I want to replace parent name with sub customer

Answer 1

You can Set and get Customer session by using Magento\Customer\Model\Session

protected $customerSession;

public function __construct(   
    \Magento\Customer\Model\Session $customerSession
){
    $this->customerSession = $customerSession;
}

$this->customerSession->setMyValue('test');
$this->customerSession->getMyValue();

Or by object manager.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $objectManager->create('Magento\Customer\Model\Session');
$customerSession->setMyValue('test');
$customerSession->getMyValue();

Please try to below code. But make sure you need to logged in.

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

$storeManager = $objectManager->get('\Magento\Store\Model\StoreManagerInterface');
$websiteId = $storeManager->getStore()->getWebsiteId();

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerRepository = $objectManager->create('Magento\Customer\Api\CustomerRepositoryInterface');

$customerSession = $objectManager->create('Magento\Customer\Model\Session');
if ($customerSession->isLoggedIn()) {
    echo 'Customer Id: ' . $customerSession->getCustomer()->getId() . '<br/>';
    echo 'Customer Name: ' . $customerSession->getCustomer()->getName() . '<br/>';
    echo 'Customer Email: ' . $customerSession->getCustomer()->getEmail() . '<br/>';

    $id = $customerSession->getCustomer()->getId() ;

    $customer = $customerRepository->getById($id);
    $firstName ='Sarvesh 1';
    $lastName ='Patel 1';

    $customer->setFirstname($firstName);
    $customer->setLastname($lastName);
    $customerRepository->save($customer);
}

But Make sure after run this code logout and try again login. Hope it works!
