I have newsletter in my magento website. I have enable confirmation before subscription from admin configuration. User are getting confirmation link in mail.
But I want to set expiry of that link. Is magento provide default config ?
How can I set expiry of that link ?

Answer 1

I found the solution. I just did two things.
1) Add created_at field in newsletter_subscriber table.
2) Overwrite the following file
vendor/magento/module-newsletter/Model/Subscriber.php
to
Company/name/Model/Subscriber.php
Overited Subscriber.php file code
public function confirm($code) // existing function
{
$id = $this->getId();
if ($this->validateConfirmLinkToken($id, $code)) {
if ($this->getCode() == $code) {
$this->setStatus(self::STATUS_SUBSCRIBED)
->setStatusChanged(true)
->save();
$this->sendConfirmationSuccessEmail();
return true;
}
return false;
}
}
private function validateConfirmLinkToken($customerId, $code) //check validation for token
{
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$messageManager = $objectManager->get('Magento\Framework\Message\ManagerInterface');
if (empty($customerId) || $customerId < 0) {
$this->_messageManager->addError('Sorry you have not rigts to access this page');
return false;
}
if (!is_string($code) || empty($code)) {
$params = ['fieldName' => 'code'];
//$messageManager->addError('Sorry Your subscription confirmation code is not valid.');
return false;
}
$dcode = $this->getCode();
$dcreated_at = $this->getCreatedAt();
if (trim($dcode) != trim($code)) {
//$messageManager->addError('Sorry Your subscription confirmation code is mismatch.');
return false;
} elseif ($this->isConfirmationLinkTokenExpired($dcode, $dcreated_at)) {
//$messageManager->addError('Sorry Your subscription confirmation code is expired.');
return false;
}
return true;
}
public function isConfirmationLinkTokenExpired($dcode, $dcreated_at) // check expiration token
{
if (empty($dcode) || empty($dcreated_at)) {
return true;
}
$expirationPeriod = '720';
$currentTimestamp = (new \DateTime())->getTimestamp();
$tokenTimestamp = (new \DateTime($dcreated_at))->getTimestamp();
if ($tokenTimestamp > $currentTimestamp) {
return true;
}
$hourDifference = floor(($currentTimestamp - $tokenTimestamp) / (60 * 60));
if ($hourDifference >= $expirationPeriod) {
return true;
}
return false;
}
Hope it will helps to many.
Thanks.
