Many thanks!

I’m running out of patients on this. Does anyone know of a simple way to highlight multiple categories in a list on single.php?

My current code only brings up a single category, it uses wp_list_categories, intended for archive pages i know. Strange that there is not yet a function for the single post template. Or is there?

<?php $catsy = get_the_category();
$myCat = $catsy[0]->cat_ID;
wp_list_categories(array(
'title_li' => '',
//ONE AT A TIME PLEASE 0_0
'current_category' => $myCat ?>

It shouldn’t have to be a massive hack.
Here’s one of the posts with only one category showing:
https://www.purkiss-archive.eu/hambling-maggi/
There should be two.

I was able to do the trick for Categories/Single Posts, with this:

// Filter to add the "current-cat" class to categories list in Single Post (https://www.transformationpowertools.com/wordpress/highlight-post-categories-function/2)
	// --------------------------------------------------------------------
	add_filter('wp_list_categories','style_current_cat_single_post', 10, 2);

	function style_current_cat_single_post($output) {

		if(is_singular()):
			global $post;
			$categories = wp_get_post_categories($post->ID);

			foreach($categories as $value) {
				if(preg_match('#item-' . $value . '">#', $output)) {
					$output = str_replace('item-' . $value . '">', 'item-' . $value . ' current-cat">', $output);
				}
			}
		endif;
		return $output;
	}

I’d like to do the same for Taxonomies/Custom Post Types, and I am close with this:

add_filter('wp_list_categories', 'sgr_show_current_cat_on_single', 10, 2);

	function sgr_show_current_cat_on_single($output, $args) {

		if (is_single()) :
	    global $post;
		    $terms = get_the_terms($post->ID, $args['shop-categories']);

		    foreach($terms as $term) {
		    	if (preg_match('#cat-item-' . $term ->term_id . '#', $output)) {
		        	$output = str_replace('cat-item-'.$term ->term_id, 'cat-item-'.$term ->term_id . ' current-cat', $output);
				}
			  }
		endif;
		return $output;
	}

But that highlights ALL the terms from the list.

By the way, I get the list from this:

<ul id="sub-nav">
			<?php wp_list_categories('title_li=&taxonomy=shop-categories'); ?>
		</ul>

Anyone knows the trick?

Wassup? I tried to find the solution of my problem but I can’t find it anywhere… I hope someone will be a wordpress master to help me

here is my problem:

I have a custom post type called “produits” using taxonomy for this post type called “filtres”. To display the taxonomy list I use this code:

$orderby = 'name';
$show_count = 0; // 1 for yes, 0 for no
$pad_counts = 0; // 1 for yes, 0 for no
$hierarchical = 1; // 1 for yes, 0 for no
$taxonomy = 'filtres';
$title = '';

$args = array(
  'orderby' => $orderby,
  'show_count' => $show_count,
  'pad_counts' => $pad_counts,
  'hierarchical' => $hierarchical,
  'taxonomy' => $taxonomy,
  'title_li' => $title
);
?>

<?php
wp_list_categories($args);
?>

Everything works fine! I need to highlight the current-cat so I used the CSS to do that and it works! Going in the taxonomy, highlighting work too ! The problem is when I visit a single post of my post type, the current-cat doesn’t appear in the <li > < /li>

Does anyone know how to add the “current-cat” class to my wp_list_categories in a single post type?

Thanks a lot guys, you’ll make my day !

BTW HAPPY NEW YEAR !

<?php wp_list_categories( array (
					'taxonomy'	=>	'uniquetaxonomy',
					'current_category'	=>	1,
					'title_li'	=>	''
				)); ?>

I’ve failed to find a solution online, I’m hoping someone might have a work around for this.

Cheers

I have created a custom post type called “prodotti” and a taxonomy called ‘categorie’.

Now when I retrieve in the taxonomy archive page (taxonomy-categorie.php) the category listing it works perfectly but it doesn’t display at all the “current-cat” class.

My code in functions .php

Anyone can help? Thanks in advance.

(Don’t bother asking why I need it to be something else. It’s a long story. )
