Extended Body Classes – Revisited

WordPress 2.8+ gave us a a lot of new sets of classes for the body post and comment areas. That will allow designers to use those tags in designing their site. These tags are ‘dynamically generated’ when certain events or pages are loaded. To enable your theme to use those tags you just have to do a little editing to your theme.

<body <?php if (function_exists('body_class')) { body_class(); } >>

On Frumph.NET and other WordPress / ComicPress sites, there’s a plethora of different customizations you can do. Per page, per category, if the page is in the comic category and more. In example on this site for this page if you were to go to page 2 of this post.

<body class="single single-post postid-220 logged-in paged-2 single-paged-2 user-admin sitemember noncomic gecko single-category-wordpress single-author-admin am day morning tue layout-3c">

All of these can be used to design your site by just placing one of those before the element you want to use.

WordPress – Plugin & Theme Check for Multisite/WPMU

by Philip M. Hofer (Frumph) on May 10th, 2010 at 9:16 am

This is some information you might need when checking whether or not the current WordPress installation is Mulsite or WPMU.

If this is a MU or Multisite WordPress this will be an option available, if it is not, it won’t be there. fileupload_url contains http://domain.tld/files which is used to rewrite the location of the wp-content/blogs.dir/#/files where the # is the blog ID number of the current blog being processed.

get_option('fileupload_url');

The MU / Multisite change to the option upload_path changes the information from wp-content/uploads to wp-content/blogs.dir/#/files where the # is the blog ID number of the current blog being processed.

get_option('upload_path');

When coding your plugin or theme that will access the uploads directory those two options are important to know the distinction between the MultiSite(MU) and single installations of WordPress.

The following bit of code is something to add to your plugin or theme if you need to determine whether or not the theme is Multisite or not. With ComicPress we use it to find the proper directory to load comics into.

function yourtheme_this_is_multsite() {
	global $wpmu_version;
	if (function_exists('is_multisite'))
		if (is_multisite()) return true;
	if (!empty($wpmu_version)) return true;
	return false;
}

The $wpmu_version was a way in WPMU <= 2.9.2 to determine if it was a WordPress MU install and the is_multisite() || VHOST is a way to determine if it’s a WordPress > 3.0 installation.

For example, with ComicPress we use it to make sure we’re pointing to the right spot to find the comics.

if (comicpress_this_is_multisite()) { $path_to_use = get_option('fileupload_url'); }

Of course we could also do:

$mu_path = get_option('fileupload_url');
if (!empty($mu_path)) $path_to_use = $mu_path;

But it’s not as reliable.
