Pass Woocommerce Order Id From Another Page To Javascript Variable On Current Page

Background We have changed the checkout process slightly in WooCommerce Usually, a user goes: Order Checkout --> Thank you Page (where Order ID appears) --> Upsell page Now i

Solution 1:

I would not use javascript but would use wc_get_customer_last_order( $customer_id ); on your upsell page to get the lastest order id

// Get user id$customer_id = get_current_user_id();

// Get last order$last_order = wc_get_customer_last_order( $customer_id );

// Get order id$order_id = $last_order->get_id();

echo$order_id;

// EDIT: if you like to use the order id as javascript variable, you can do this in the following way?>
<script type="text/javascript">
jQuery(document).ready(function ($) {
    var order_id = <?phpecho$last_order->get_id(); ?>;
    console.log(order_id);
});
</script>
<?php

if you don't have access to the $customer_id (depending on whether guests can order without an account on your webshop?)

You could use a sql query instead to get the latest order ID
