Magento 1 Variable to check if customer is subscribed to newletter

Question

Is there a variable I can include in the transactional emails to show whether the customer has subscribed to the Newsletter or not?

Answer 1

In app\code\core\Mage\Sales\Model\Order.php there is a function sendNewOrderEmail() you can see this code:

$mailer->setTemplateParams(array(
                'order'        => $this,
                'billing'      => $this->getBillingAddress(),
                'payment_html' => $paymentBlockHtml
            )
        );

in same function you can check if customer is subscribed to newsletter or not like using this code:

$subscriber = Mage::getModel('newsletter/subscriber')->loadByEmail($this->getCustomerEmail());
if ($subscriber->getId()) {
     $is_subscribed=true;
}
else{
$is_subscribed=false;
}

then you can pass this variable in in setTemplateParams like:

$mailer->setTemplateParams(array(
                'order'        => $this,
                'billing'      => $this->getBillingAddress(),
                'payment_html' => $paymentBlockHtml,
                'is_subscribed' = > $is_subscribed
            ));

then in email template you can check like this

{{if is_subscribed}}

Note: override this function instead of making changes in core code

Answer 2

You can check customer by email if the email is already in subscribe list

$subscriber = Mage::getModel('newsletter/subscriber')->loadByEmail($email); if ($subscriber->getId()) { // put your logic here... }

Or if you have customer ID then you can directly check in newsletter_subscriber table to check if customer ID exists or not.
