Notice: Undefined variable: order in C:xampppserver2htdocsmrdigitalwp-contentthemesastra-childtestmpdf.php on line 22

Fatal error: Uncaught Error: Call to a member function get_order_number() on null in C:xampppserver2htdocsmrdigitalwp-contentthemesastra-childtestmpdf.php:22 Stack trace: #0 {main} thrown in C:xampppserver2htdocsmrdigitalwp-contentthemesastra-childtestmpdf.php on line 22

This is the line 22
$order = $_GET[$order->get_order_number()];

$mpdf = new MpdfMpdf([
    'mode' => 'utf-8',

    Thank you so much for the help. This is how i have turned around the situation.

    1° You need to know that i customised my mPDF Composer installation inside my Template-Child and NOT inside the Default Root Folder.

    2° I must definitivily to make reference to the Wordpress wp-config.php file, other wise this never would worked because of my customised installation.

    3° I must definitivily to make reference to the Woocommerce Class class-wc-order.php file.

    4° Now as follows in the code, i can receive the order object and manipulate what i need.

    Code:

    <?php

// Root Directory WP Config
require_once '/xampppserver2/htdocs/mrdigital/wp-config.php';   

// Root Directory CLASS WC ORDER
require_once '../../plugins/woocommerce/includes/class-wc-order.php';   

// Load MPDF Loader
require_once __DIR__ . '/vendor/autoload.php';

use MpdfMpdf;

$mpdf = new Mpdf();
$mpdf = new MpdfMpdf(['tempDir' => __DIR__ . '/custom/temp/dir/path']);

    $order = new WC_Order($_GET['key']);

    You need to run it after wc_get_order has been created, and also, find an easy way to get the order id. this is my proposed solution below.

    <?php
/**
 * @Author: exame
 * @Last Modified time: 2020-11-05 15:47:01
 */
use MpdfMpdf;

require_once __DIR__ . '/vendor/autoload.php';



function pekky_print_pdf( $order_id ) {
$mpdf = new Mpdf();

$mpdf = new MpdfMpdf(['tempDir' => __DIR__ . '/custom/temp/dir/path']);

$mpdf = new MpdfMpdf([
    'mode' => 'utf-8',    
    'orientation' => 'P',
    'format' => 'A4'
]);

$order = wc_get_order( $order_id ); 

$html = '
