   Hi,

   In my plugin Top 10, below is the code:

   add_action('wp_head','tptn_add_viewed_count');
   function tptn_add_viewed_count() {
   	global $post, $wpdb, $single;
   	$table_name = $wpdb->prefix . "top_ten";
   	$tptn_settings = tptn_read_options();
   
   	$current_user = wp_get_current_user();
   	$post_author = ( $current_user->ID == $post->post_author ? true : false );
   
   	if((is_single() || is_page())) {
   echo '<!-- Top 10 : '.$current_user->ID.' & '.$post->post_author.' -->';
   		 if (!(($post_author)&&(!$tptn_settings['track_authors'])))  {
   			$id = intval($post->ID);
   			$output = '<script type="text/javascript" src="'.get_bloginfo('wpurl').'/wp-content/plugins/top-10/top-10-addcount.js.php?top_ten_id='.$id.'"></script>';
   			echo $output;
   		}
   	}
   }

   I have noticed that this doesn't work anymore, the $post->post_author and $current_user->ID both return blank values.

   This wasn't a problem before I upgraded to 2.9. Can anyone else confirm this?

   I have several installations, and the $current_user function seems to be broken on my 2.9 installation. Let me know if you figure this one out. [email moderated]

   I made a workaround for this issue on my WP 3.0 install:

   <?php
   $thisuser = wp_get_current_user();
   if ( 0 == $thisuser->ID ) {  // Not logged in.
   } else {  // Logged in.
   echo '<li><a href="' . get_option('siteurl') . '/wp-admin/profile.php">Logged in as ' . $thisuser->display_name .'</a></li>';
   }
   ?>

   I'm having the same problem. Did anyone find a good solution to the problem?

   wp_get_current_user() returns false, and it's because $current_user is empty.

   When you log into WP, in which function or class is this variable instatiated with a user object?

   The wp_get_current_user() function appears to work fine for me (2.9.2 ->). Make sure its called after testing if the user is logged otherwise it will return NULL.

   @torvad - $current_user var is populated by the function call. If the function returns NULL then the var will be empty.

   As @ibr shows - you need to test if the user is logged in before making the function call. Here's a similar way to test,

   <?php global $user;
       if (is_user_logged_in()) {
           $user = wp_get_current_user();
            ......

   is_user_logged_in() returns false inside the function &get_posts() which is in query.php

   When you edit a post in WP the file admin/post.php is called. I checked and found out that is_user_logged_in() returns true in this file.

   Why does it return false inside query.php? I am logged in...

   Is there a function that logs off the user when calling this file?
