Answer 1

1. Including javascript :

To include javascript in wordpress plugin,normally we use

wp_enqueue_script('PATH_TO_JAVASCRIPT');

But this include javascript in both front side and admin side of site, if that plugin is active.

If you want to activate it on only admin side use

if(is_admin()){ wp_enqueue_script('PATH_TO_JAVASCRIPT'); }

2 . Using wordpress classes, objects, functions outside wordpress:

To use wordpress classes, objects, functions outside wordpress, simple include wp-load.php file in your script

<?php include_once 'wp-load.php';?>
