Current Category at Single entries

    Hi!

    I’m currently developing a WordPress theme with a nav bar on the top of the site. In the nav bar I have used <?php wp_list_categories(); ?> . I have also used the current-cat CSS tag to say that if you select a category the link will be highlighted. This works just fine.

    But I have a question:

    If you enter a single entry from the front page, how can I make the category which the entry belongs to highlight?

    Thanks for reading!
    I hope someone has a nice solution. ??

  • you probably have something like this for your cat nav:

    <ul>
<?php wp_list_categories('title_li='); ?>
</ul>

    you could try and replace it with this snippet:

    <?php
if(is_single()) :
$categories = wp_get_post_categories($post->ID);
foreach ($categories as $catid) {
$cat = get_category($catid);
$cats[] = $cat->cat_ID;
 }

$cats_list =  wp_list_categories( 'echo=0&title_li=');  

foreach($cats as $value) {
	if(preg_match('#item-' . $value . '">#', $cats_list)) {
	$cats_list = str_replace('item-' . $value . '">', 'item-' . $value . ' current-cat">', $cats_list);
	}
	}

echo '<ul>'.$cats_list.'</ul>';

else :
//use default category list
echo '<ul>';
wp_list_categories('title_li=&');
echo '</ul>';

endif;
?>

    as a single post can have more than one category, this will highlight all cats that are in the post.

    hope this helps and works ??

    Wow! It worked brilliantly! ?? Very nice. Thank you so much!

    thanks helped me too ^^

    changed this line to list childs categories

    $cats_list = wp_list_categories( 'echo=0&child_of=3&title_li=');

    Hi,
    I have this already coded and I have tried to implement your solution above but i keep messing up the page layout.

    Here’s my code:

    <div id="nav">
			<ul>

			<li<?php
                if (is_home())
                {
                echo " id=\"current\"";
                }?>>
                <a href="<?php bloginfo('url') ?>">Home</a>
        </li>

			<?php wp_list_categories('title_li'); ?>
			<?php wp_list_pages('title_li' ); ?>
			</ul>
		</div>

    Any help would be appreciated thanks.
