Are you looking for a way to include any file you want without having to print out the whole URL? While there’s probably a plugin for this, we have created a quick code snippet that you can use to include any file without URL in WordPress.
All you have to do is add this code to your theme’s index.php file or in a site-specific plugin:
<?php get_template_part( 'filename' ); ?>
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly copy / paste code snippets in WordPress, so you don’t accidentally break your site.
