Comment Post Redirect

Prerequisite: WordPress installed in sub-directory.

Just in case anyone else is looking to redirect users back to the post they just posted a comment on and have it scroll to the last posted comment from that user without hacking core files:

Add this to your themes functions.php file.

add_filter('comment_post_redirect', 'redirect_after_comment');
function redirect_after_comment($location)
{
	global $wpdb;
	return $_SERVER["HTTP_REFERER"]."#comment-".$wpdb->insert_id;
}
