The Extended Body Class Function

Theme designs can benefit from using an extra set of body_classes that do a variety of things, these are the ones that we use on ComicPress 2.8.1+ adapt this code to fit for you.

add_filter('body_class','comicpress_body_class');

function comicpress_body_class($classes = '') {
	global  $current_user, $is_lynx, $is_gecko, $is_IE, $is_opera, $is_NS4, $is_safari, $is_chrome, $is_iphone, $post, $wp_query, $comicpress_options;

	if (!empty($current_user)) {
		$user_login = addslashes($current_user->user_login);
		if (!empty($user_login)) $classes[] = 'user-'.$user_login;
	} else {
		$classes[] = 'user-guest';
	}

	if (function_exists('comicpress_is_member')) {
		if (comicpress_is_member()) {
			$classes[] = 'sitemember';
		} else {
			$classes[] = 'non-sitemember';
		}
	}
		
	if (is_single() && !is_attachment()) {
		if (in_comic_category()) {
			$classes[] = 'comic';
		} else {
			$classes[] = 'noncomic';
		}
	}

	if($is_lynx) $classes[] = 'lynx';
	elseif($is_gecko) $classes[] = 'gecko';

	else $classes[] = 'unknown';
	if($is_iphone) $classes[] = 'iphone';


// Hijacked from the hybrid theme, http://themehybrid.com/
	if (is_single()) {
		foreach ( (array)get_the_category( $wp_query->post->ID ) as $cat ) :
			$classes[] = 'single-category-' . sanitize_html_class( $cat->slug, $cat->term_id );
		endforeach;
		$classes[] = 'single-author-' . get_the_author_meta( 'user_nicename', $wp_query->post->post_author );
	}

	if ( is_sticky( $wp_query->post->ID ) ) {
		$classes[] = 'sticky-post';
	}

// NOT hijacked from anything, doi! people should do this.
	$rightnow = date('Gi');
	$ampm = date('a');
	$classes[] = $ampm;

	if ((int)$rightnow > 559 && (int)$rightnow < 1800) $classes[] = 'day';
	if ((int)$rightnow < 600 || (int)$rightnow > 1759) $classes[] = 'night';
	
	if ((int)$rightnow > 2329 || (int)$rightnow < 0030) $classes[] = 'midnight';
	if ((int)$rightnow > 0559 && (int)$rightnow < 1130) $classes[] = 'morning';
	if ((int)$rightnow > 1129 && (int)$rightnow < 1230) $classes[] = 'noon';
	if ((int)$rightnow > 1759 && (int)$rightnow < 2330) $classes[] = 'evening';
	
	$classes[] = strtolower(date('D'));

	if ( is_attachment() ) {
		$classes[] = 'attachment attachment-' . $wp_query->post->ID;
		$mime_type = explode( '/', get_post_mime_type() );
		foreach ( $mime_type as $type ) :
			$classes[] = 'attachment-' . $type;
		endforeach;
	}

	$classes[] = 'layout-'.$comicpress_options['cp_theme_layout'];

	return $classes;
}

You probably won’t be needing the sitemember and layout classes since they are fundamentally only for the ComicPress / CommPress themes.
