Προσθήκη του Facebook Capi purchase event στην thank you σελίδα στο woocommerce

1. Make sure you have the Facebook Pixel installed on your website and that it is properly configured.
2. Add the following code to your theme’s functions.php file or a custom plugin:

add_action( ‘woocommerce_thankyou’, ‘facebook_purchase_event’ );
function facebook_purchase_event( $order_id ) {
if ( ! $order_id ) {
return;
}

// Get the order object
$order = wc_get_order( $order_id );
$total = $order->get_total();
$currency = $order->get_currency();
$content_ids = array();
$content_type = ‘product’;

// Loop through order items
foreach ( $order->get_items() as $item ) {
$product = $item->get_product();
$content_ids[] = $product->get_id();
}

// Prepare the event data
$event_data = array(
‘value’ => $total,
‘currency’ => $currency,
‘content_ids’ => implode( ‘,’, $content_ids ),
‘content_type’ => $content_type,
);

// Trigger the “Purchase” event
?>
<script>
fbq(‘track’, ‘Purchase’, <?php echo json_encode( $event_data ); ?>);
</script>
<?php
}

This code will trigger the “Purchase” event on the Facebook Pixel when a customer is directed to the thank you page after completing a purchase. It will also include the purchase value, currency, and the product IDs in the event data.
