Highlight Current Category in Navbar on Single Page

Here’s what I have and it works for all single pages, how do I specify if I want it active on category ID 2 only?

<li <?php if(is_single()){echo ‘class=”current-cat”‘;}?>>

in_category?

Got that to work, trying to make that work for in_category as well as is_category. Just need to rewrite this so it also has is_category(5)) but I don’t know how to do both. Sorry Moshu, I’m a lame-o this morning.

<li <?php if(in_category(5)){echo ‘class=”current-cat”‘;}?>>

in_category should work on single
is_catgeory should work on cat archives

EDIT. Seemingly, we posted in the same time…

Right, that I know – but I’m hoping to get the blog link active when it’s doing either or. On the Blog category/archive page or when it’s a single post within the blog category. Make sense?

Use an or statement
<li <?php if(in_category(5) || is_category(5)){echo 'class="current-cat"';}?>>

This is untested.

Jeremy, thanks man, this worked.

what if I fulled categories with the following code:

<ul id="nav">
<li><a href="https://www.site.com/category1">Category1</a></li>
<li><a href="https://www.site.com/category2">Category2</a></li>
</ul>

I cannot pull all categories because there are too many. Is there a way to pull only main categories? Thanks

Like I understand you have to manually enter:

<li <?php if(in_category(5) || is_category(5)){echo 'class="current-cat"';}?>>

for every category that you have, is that right?

But is there a way to do this automatically?

I mean, is there a way to edit ‘category-template.php’ file and do something with wp_list_categories function, that it would automatically generate list with the effect mentioned above?

I have almost the same problem. When i am on categories current category is highlighted…when i go to single post the category is not “current-cat” anymore.

Is there a workaround to use “wp_list_categories” on single post to highlight current category or at least parent category in which the post is?

Hi everyone!
I was looking for the very same thing, but finding nothing on the web I built a fix myself.

So this is for you if:

– you are using wp_list_categories
– you want to add the current-cat attribute when reading a single post

What to do:

in wp-include/category-template.php

after line 313

add:

if ( is_single() ) {

		$blork = get_the_category();
		$r['current_category'] = $blork[0]->cat_ID;
		}

Does your solution brake something elsewhere on blog or is safe to use? Tnx

hi joandiego,

Thank you for sharing. It’s exactly what I’m looking for.

Thanks!
Works like a charm in 2.6 too.

I’m glad it works on 2.6
Happy coding.
