The below code is for sorting of posts within a category and what not. You call it by using ?sort=name&dir=ASC at the end of a category example: http://yourwordpress.com/videos/?sort=name&dir=ASC
<?php $sortby = $_GET['sort']; ?>
<?php $dir = $_GET['dir']; ?>
<?php
$wp_query->query('cat=7&showposts=5&order='.$dir.'&orderby='.$sortby );
?>
<?php while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<?php the_title(); ?>
<?php endwhile; ?>You can see the things that you can order by at ttp://codex.wordpress.org/Template_Tags/get_posts under the $orderby section.
