wordpress plugin -> Call to undefined function wp_

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()

Apparently this is happening because the file /wp-includes/pluggable which contains the function doesn't get loaded until after the plugins are loaded.

Anybody any ideas on how to get the user details in my plugin?

Apparently this is happening because the file /wp-includes/pluggable which contains the function doesn't get loaded until after the plugins are loaded.

Indeed it is. So wrap whichever thing you're doing in a function, and hook it onto the plugins_loaded or init hook. (see the wp-settings.php file)

Example:

add_action('init','do_stuff');
function do_stuff(){
  $current_user = wp_get_current_user();
  // ...
}

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 3

Quick fix include_once(ABSPATH . 'wp-includes/pluggable.php'); add this line on your capabilities.php
