add a function where in thank you page in woocommerce wordpress the google analytics 4 purchase event is implementent

To add a function where a Google Analytics 4 purchase event is implemented on the “Thank You” page in WooCommerce for WordPress, you can use the following steps:

1. Install the Google Analytics for WordPress plugin, which allows you to easily add GA4 tracking code to your website.
2. Create a GA4 property and get the tracking code from the GA4 admin.
3. Add the GA4 tracking code to your website using the Google Analytics for WordPress plugin.
4. Create a custom function in your theme’s functions.php file that fires the GA4 purchase event when the “Thank You” page is loaded.
5. In this function, use the JavaScript gtag('event', 'purchase', {'value':'[value]','currency':'[currency]'}); command to fire the purchase event and pass in the transaction value and currency.
6. Add the function to the “Thank You” page using the WooCommerce woocommerce_thankyou action hook.

example

function ga4_purchase_event() {
global $wp;
if ( is_wc_endpoint_url( ‘order-received’ ) ) {
$order_id = $wp->query_vars[‘order-received’];
$order = wc_get_order( $order_id );
$total = $order->get_total();
$currency = get_woocommerce_currency();
echo “<script>gtag(‘event’, ‘purchase’, {‘transaction_id:’$order,’value’:’$total’,’currency’:’$currency’});</script>”;
}
}

Next, you need to add the function to the “Thank You” page using the WooCommerce woocommerce_thankyou action hook like this:

add_action( ‘woocommerce_thankyou’, ‘ga4_purchase_event’ );
