Product Events Implementation

ViewContent Event (Product Page)

Track when users view product detail pages.

Observer Method

File: Observer/ViewContent.php

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Registry;
use Magento\Checkout\Model\Session as CheckoutSession;

class ViewContent implements ObserverInterface
{
    protected $registry;
    protected $checkoutSession;

    public function __construct(
        Registry $registry,
        CheckoutSession $checkoutSession
    ) {
        $this->registry = $registry;
        $this->checkoutSession = $checkoutSession;
    }

    public function execute(Observer $observer)
    {
        $product = $this->registry->registry('current_product');

        if ($product) {
            $eventData = [
                'content_name' => $product->getName(),
                'content_ids' => [$product->getSku()],
                'content_type' => 'product',
                'value' => (float)$product->getFinalPrice(),
                'currency' => $this->getCurrency()
            ];

            $this->checkoutSession->setMetaPixelViewContent($eventData);
        }
    }

    protected function getCurrency()
    {
        return 'USD'; // Implement proper currency detection
    }
}

Register: etc/frontend/events.xml

<event name="controller_action_predispatch_catalog_product_view">

if ($eventData):
?>
<script>
    require(['jquery'], function($) {
        fbq('track', 'ViewContent', {
            content_name: '<?= $block->escapeJs($eventData['content_name']) ?>',

        });
    });
</script>
<?php
    $block->getCheckoutSession()->unsMetaPixelViewContent();
endif;
?>

            $xml .= '<g:link>' . $product->getProductUrl() . '</g:link>';
            $xml .= '<g:image_link>' . $product->getImage() . '</g:image_link>';

}

Advanced Matching

Improve match rates by sending hashed customer data.

Implementation:

fbq('init', 'PIXEL_ID', {
    em: 'HASHED_EMAIL',
    fn: 'HASHED_FIRST_NAME',
    ln: 'HASHED_LAST_NAME',
    ph: 'HASHED_PHONE',
    ct: 'HASHED_CITY',
    st: 'HASHED_STATE',
    zp: 'HASHED_ZIP',
    country: 'HASHED_COUNTRY'
});

Server-Side Hashing (Helper):

public function getAdvancedMatchingData()
{
    if (!$this->customerSession->isLoggedIn()) {
        return [];
    }

    $customer = $this->customerSession->getCustomer();
    $address = $customer->getDefaultBillingAddress();

    return [
        'em' => hash('sha256', strtolower($customer->getEmail())),
        'fn' => hash('sha256', strtolower($customer->getFirstname())),
        'ln' => hash('sha256', strtolower($customer->getLastname())),
        'ph' => hash('sha256', preg_replace('/[^0-9]/', '', $address->getTelephone())),
        'ct' => hash('sha256', strtolower($address->getCity())),
        'st' => hash('sha256', strtolower($address->getRegion())),
        'zp' => hash('sha256', $address->getPostcode()),
        'country' => hash('sha256', strtolower($address->getCountryId()))
    ];
}

Testing & Validation

Meta Pixel Helper

  1. Install Chrome extension
  2. Visit Magento store
  3. Perform actions (view product, add to cart, purchase)
  4. Verify events fire in extension popup

Events Manager Test Events

  1. Facebook Business Manager > Events Manager
  2. Select Pixel > Test Events
  3. Perform actions on site
  4. Verify events appear in real-time

Browser Console Debugging

// Enable debugging
fbq.debug = true;

// Check queue
console.log(fbq.queue);

// Manual event test
fbq('track', 'AddToCart', {
    content_ids: ['TEST123'],
    value: 10.00,
    currency: 'USD'
});

Performance Optimization

Event Deduplication

Prevent duplicate events between client and server:

public function sendEvent($eventName, $eventData, $userData = [])
{
    $payload = [
        'data' => [
            [
                'event_name' => $eventName,
                'event_time' => time(),
                'event_id' => $this->generateEventId($eventName), // Unique ID
                'event_source_url' => $this->getCurrentUrl(),
                'action_source' => 'website',
                'user_data' => $this->formatUserData($userData),
                'custom_data' => $eventData
            ]
        ]
    ];

    // Send to Conversion API...
}

protected function generateEventId($eventName)
{
    return hash('sha256', $eventName . time() . uniqid());
}

Client-side:

var eventId = 'unique_event_id_12345';
fbq('track', 'Purchase', {
    value: 100.00,
    currency: 'USD'
}, {eventID: eventId});

Troubleshooting

Events Not Appearing

Solutions:

  1. Check pixel ID is correct
  2. Verify Meta Pixel Helper shows pixel loaded
  3. Check browser console for errors
  4. Ensure events are registered properly

Duplicate Events

Solutions:

  1. Implement event deduplication
  2. Check for multiple pixel installations
  3. Review GTM and direct implementations

Low Match Quality

Solutions:

  1. Enable Advanced Matching
  2. Implement Conversion API
  3. Send more user parameters
  4. Hash data properly (lowercase before hashing)
