Magento – Newsletter subscription at the checkout review

customerevent-observermagento-1.9newsletteronepage-checkout

Expected functionality: user checks the "Subscribe" checkbox in the OnePage Checkout's review step and is subscribed to the newsletter.

So far I have managed to target the right event (after submitting checkout form):

config.xml

<events>        
    <checkout_submit_all_after>
        <observers>
            <checkout_newsletter>
                <class>News_Custom_Model_Observer</class>
                <method>assignNewsletter</method>
            </checkout_newsletter>
        </observers>
    </checkout_submit_all_after>   
</events>

info.phtml contains

<div class="text-left mt10 mb30">
     <div class="input-checkbox">
        <input id="subscribe_newsletter" type="checkbox" name="is_subscribed" value="1" checked="checked">
        <label for="is_subscribed">Subscribe for newsletter</label>
    </div>
</div>

Observer.php

public function assignNewsletter(Varien_Event_Observer $observer) 
{
    $event = $observer->getEvent();
    $order = $event->getOrder();
    $quote = $event->getQuote();

    if ($observer->getRequest()->getParam('is_subscribed', false)) {
        Mage::log('got here');
        Mage::getModel('newsletter/subscriber')->subscribe($quote->getCustomerEmail());
    } else {
        Mage::log($observer->getRequest()->getParams());
    }
}

What happends is that $observer->getRequest()->getParams() only contains shipping method. So the issue is to pass/capture the data from checkout view to observer.

Any help or guidance is much appreciated.

  • First, make sure that you template code iss inside a <form> tag.

    <form action="" id="checkout-review" onsubmit="return false;">
    ...
    <div class="text-left mt10 mb30">
        <div class="input-checkbox">
            <input id="subscribe_newsletter" type="checkbox" name="is_subscribed" value="1" checked="checked">
            <label for="is_subscribed">Subscribe for newsletter</label>
        </div>
    </div>
    ...
</form>

  • add first observer to controller_action_predispatch_checkout_onepage_saveOrder to store user input in checkout session

    public function checkoutSaveOrder(Varien_Event_Observer $observer)
{
    $subscribe = $observer->getEvent()
        ->getControllerAction()
        ->getRequest()
        ->getParam('is_subscribed', 0);

    Mage::getSingleton('checkout/session')->setIsSubscribed($subscribe);

    return $this;
}

  • add second observer to checkout_type_onepage_save_order_after to subscribe user after order is placed

    public function checkoutSaveOrderAfter(Varien_Event_Observer $observer)
{
    $subscribe = Mage::getSingleton('checkout/session')->getIsSubscribed();

    if ((bool)$subscribe) {
        $email = $observer->getOrder()->getCustomerEmail();
        Mage::getModel('newsletter/subscriber')->subscribe($email);
    }
    return $this;
}
