Will this code snippet in the functions.php insert the JS tracking code onto the order confirmation page, so that I can track it with Google Tag Manager?
function send_purchase_data_to_gtm($order_id) {
// Get the order object
$order = wc_get_order($order_id);
// Check if the order exists
if (!$order) {
return;
}
// Get order data
$value = $order->get_total();
$currency = $order->get_currency();
$transaction_id = $order->get_order_number();
$items = [];
// Loop through the order items
foreach ($order->get_items() as $item) {
$product = $item->get_product();
$items[] = [
‘item_id’ => $product->get_id(),
‘item_name’ => $product->get_name(),
‘quantity’ => $item->get_quantity(),
‘item_brand’ => ”, // Replace with the brand if available
‘item_category’ => ”, // Replace with the category if available
‘price’ => $product->get_price()
];
}
?>
