Wordpress和PHP - get_currentuserinfo（）;

Question

I have searched to the end of the internet and can't seem to find anything that helps me with my issue. I have a wordpress site (inherited) and I simply want to be able to obtain a user's information when they're logged in. From the documentation I see to use get_currentuserinfo() but when I try to use it I get nothing.

The file resides in a folder in my main html directory. Here are the contents:

<?php 
include_once("../wp-includes/pluggable.php"); 
  global $current_user;
  get_currentuserinfo();
  echo $current_user->user_login;


?>

I'm literally losing my mind over this. Is there something else I need to include at the top? Do I have to create the page within wordpress?

Answer 1

you must include wp-load.php to use wordpress function in php file outside wordpress

require_once("/path/to/wordpress/wp-load.php");
  global $current_user;
  get_currentuserinfo();
  echo $current_user->user_login;
