wp_list_categories( ) w/ img before-after & Show Active Category functionality (1 post)

    That title is a mouthful, but that's what I'm attempting to do. I discovered a neat trick to add elements via <span>, <div>, or otherwise in the code for each category listing here. Now the new challenge is to make this category

  2. listings show an active category for the current single page's category. Here's the code for the Show Active Category plugin:
    function show_active_category($text) {

	global $post;

	if( is_single() || is_category() ) {

		$categories = wp_get_post_categories($post->ID);

		foreach( $categories as $catid ) {
			$cat = get_category($catid);
			if(preg_match('#>' . $cat->name . '</a>#', $text)) {
				$text = str_replace('>' . $cat->name . '</a>', ' class="active-cat">' . $cat->name . '</a>', $text);
			}
		}

	}

	return $text;

}

add_filter('wp_list_categories', 'show_active_category');

    This plugin works great alone, but I'm trying to combine the two. I tried canging variable names so there's no conflict. I even changed the add_filter('wp_list_categories... to add_filter('get_categories... but that didn't work either.

    Any help would be much appreciated.

    thanks!
