Magento 2 - How to get logged in user email id using customer session

Question

I'm using Magento 2.2.6, How can I get the email ID of logged in user to show in header.

Thanks.

Answer 1

First, create an instance in header.phtml file as below and also if more than one store is available and one wants to get mail in only one of the stores.

<?php
    $objectManager =  \Magento\Framework\App\ObjectManager::getInstance();        
    $storeManager  = $objectManager->get('\Magento\Store\Model\StoreManagerInterface');
    $storeID       = $storeManager->getStore()->getStoreId(); 
    $storeName     = $storeManager->getStore()->getName();
?>

<?php
    $customerSession = $om->get('Magento\Customer\Model\Session');
    if($customerSession->isLoggedIn()) {
            echo $customerSession->getCustomer()->getEmail(); // get Email
    }
?>

Answer 2

You need to inject \Magento\Customer\Model\Session $customerSession, class to get customer ID from customer session. Try this code.

protected $_customerSession;

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

public function getCustomer()
{
    echo $this->_customerSession->getCustomer()->getId(); //Print current customer ID

    $customerData = $this->_customerSession->getCustomer(); 
    print_r($customerData->getData()); //Print current Customer Data
    echo 'Customer Id: ' . $customerData->getId() . '<br/>';
    echo 'Customer Name: ' . $customerData->getName() . '<br/>';
    echo 'Customer Email: ' . $customerData->getEmail() . '<br/>';
    echo 'Customer Group Id: ' . $customerData->getGroupId() . '<br/>';
}

NOTE: You only get customer id if customer logged in and customer session initialized
