Now do I copy all the script or part of it?
Any instructions on how to implement this?
You can use a PHP require_once() in any of your PHP pages. At the top of the php page (first line) you should put this lines of code.
<?php session_start(); ob_start(); require_once("/home/xxxxxxx/public_html/shop/frontend/load.php"); $content = ob_get_contents(); ob_end_clean(); ?>
Edit you .php page and put the code below where you want the shopping cart to appear.
<?php echo $content; ?>
