wordpress plugin -> Call to undefined function wp_get_current_user()

Question

I\'m trying to get the current user info in my plugin using the func wp_get_current_user(). But am getting Call to undefined function wp_get_current_user()

Answer 1

I got the same error message after updating WP. The fix that worked for me is quick and easy:

Locate capabilities.php in the wp-includes directory (WP 3.8.x). Add the following at the top, after the opening php tag:

require_once('pluggable.php');

Answer 2

NOT wp-includes but :

include_once(ABSPATH . "wp-admin/includes/plugin.php");

Answer 3

You can use this,

<?php
if(!function_exists('wp_get_current_user')) {
    include(ABSPATH . "wp-includes/pluggable.php"); 
}
?>

this should fix your problem :)
