短代码不能用于主题文件夹

I want to display shortcode in file Wordpress/order.php, but it is not working.I am using this php code to display echo do_shortcode('[wp-like-locker]');

But it displays this error message.

Fatal error: Call to undefined function do_shortcode() in D:
ew\htdocs\business\upload.php on line 144

I am using this code out of template folder.

How can I display this code out of tempalate folder?

To access WP functions you need to include wp-load.php:

define( 'WP_USE_THEMES', false );
require_once( '../path/to/wp-load.php' );
