 * Your PHP assumes the WordPress environment is loaded, but your JS calls directly
   to a PHP file that is not loading WordPress.
    You don’t need all of WordPress
   to read the database, so you could do that without it, but make sure that you
   haven’t left any security holes or hackers will just use it to red the passwords
   of your users. To use WordPress from JS, you can use the WordPress AJAX interface
   or the REST API.
