Amazing. It works very well with my custom taxonomies! The name of my taxonomy is directors_name so this is what I put in my functions.php
function sgr_show_current_cat_on_single($output) { global $post; if( is_single() ) { $taxonomy = 'directors_name'; $categories = wp_get_object_terms( $post->ID, $taxonomy );


		foreach( $categories as $catid ) {

			$cat = get_category($catid);

			// Find cat-item-ID in the string

			if(preg_match('#cat-item-' . $cat->cat_ID . '#', $output)) {

				$output = str_replace('cat-item-'.$cat->cat_ID, 'cat-item-'.$cat->cat_ID . ' current-cat', $output);

			}

		}

	}

	return $output;

}

add_filter('wp_list_categories', 'sgr_show_current_cat_on_single');

And this is what I put in my single.php

Thank you for your help!

Thank you very much. It works ad hoc.

Daniel,

You are quite right – the new Custom Menu functionality makes all of this so much easier. Generally, I always recommend clients to use this rather than the “traditional” method of wp_list_categories etc.

Glad you found the article useful.

Fantastic post, and great comments too – reading it pointed me in the direction of using wp_nav_menu instead of wp_list_pages or wp_list_categories

It makes everything so easy – adding classes for the first and last list item, setting up the order of list items and also styling the parent menu item if the current page is a sub page, as discussed above

If you haven’t already, do check out Justin Tadlock’s excellent walk-through of wp_nav_menu here -

Yes….can you see the solution?…If there is I not understand it. Can you explain me, please?

I need the php code to assign current class to main categories.

Thanks

Angelo,

I think this is discussed elsewhere in the comments.

Hi friends,
I followed this guide and it works great, but the single post in children categories don’t active the main items menu.

Do you have any solutions?

In fact it is much simpler if you use custom menus as WP automatically adds various classes to the menu markup. It’s a question of identifying those classes (I don’t know them off the top of my head) and then targeting them with appropriate CSS.

In case anyone is interested, the solution lies in using categories for the menu entries, instead of pages. As featured in this article.

I have this very same question. How to fit this with the custom menus of version 3.x.
