Create a plugin to send order emails to fulfillment partners based on the postcode of the delivery address

					<?php
function wpturbo_is_postcode_in_area($postcode) {
    // Add your postcode validation logic here
    // Example: Check if the postcode is in the range of 10000 to 20000
    if ($postcode >= 10000 && $postcode <= 20000) {
        return true;
    } else {
        return false;
    }
}

function wpturbo_get_fulfillment_emails() {
    // Add your logic to retrieve the email addresses of fulfillment partners
    // Example: Return email addresses based on the postcode
    $postcode = $order->get_shipping_postcode();
    if ($postcode >= 10000 && $postcode <= 15000) {
        return array('fulfillment1@example.com');
    } elseif ($postcode > 15000 && $postcode <= 20000) {
        return array('fulfillment2@example.com');
    } else {
        return array();
    }
