Khoiruddin on "[Plugin: WP Favorite Posts] Display a user's favorites when viewing their profile"

Try my crazy script inside author.php on your theme :D :

<?php
	$curauth = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author));
	global $current_user;
    get_currentuserinfo();
	$meta_query = mysql_query("
		SELECT distinct($wpdb->usermeta.meta_value) FROM
		$wpdb->posts,  $wpdb->postmeta, $wpdb->users, $wpdb->usermeta
		WHERE $wpdb->postmeta.post_id = $wpdb->posts.id
		AND $wpdb->usermeta.user_id = $wpdb->users.id
		AND $wpdb->postmeta.meta_key = 'wpfp_favorites'
		AND $wpdb->usermeta.meta_key = 'wpfp_favorites'
		AND $wpdb->users.id = '".$curauth->ID."'");

	while($array_meta = mysql_fetch_array($meta_query))
	{
		$meta = explode('"',$array_meta['meta_value']);
	}

	class IndexFilter extends FilterIterator {
		public function __construct (array $data) {
			parent::__construct(new ArrayIterator($data));
		}   

		public function accept () {
			return ($this->key() % 2);
		}
	}

	$arr_meta	= $meta;
	$posts_id = array();

	foreach (new IndexFilter($arr_meta) as $key => $value) {
    $posts_id[$key] = $value;
}
?>
<h2>Favorite Posts</h2>
<ul>
<?php
$data_posts_id = array_reverse($posts_id);
foreach($data_posts_id as $show_posts_id){
	echo '<li><a href="'.get_permalink($show_posts_id).'" title="Permanent link to '.get_the_title($show_posts_id).'">'.get_the_title($show_posts_id).'</a></li>';
}
?>

good luck :)
