This is my Block File:
<?php
namespace ChennaiBox\Mymail\Block\Mail;
class MailContent extends \Magento\Framework\View\Element\Template
{
protected $_objectManager;
protected $customerSession;
public function __construct(
\Magento\Customer\Model\Session $customerSession,
\Magento\Framework\ObjectManagerInterface $objectManager
) {
$this->customerSession = $customerSession;
$this->_objectManager = $objectManager;
}
public function mymailData()
{
try{
if ($this->customerSession->isLoggedIn()) {
$cutomerEmail =(string)$this->customerSession->getCustomer()->getEmail();
echo $cutomerEmail;
else{
$this->_redirect('customer/account/login/');
}
}catch (Exception $e) {
$e->getMessage();
}
}
}
If I call this block I get error
