I will customize the thankyou page from my WoocCommerce shop. For this I added a blanc thankyou.php into the WooCommerce checkout directory.
I tried this code
function get_order($order_id) {
echo $order_id;
}
add_action('woocommerce_thankyou', 'get_order');
But the variable $order_id is empty.
Is there somebody who knows how I get the order id on the thankyou page?
