Finding the category slug with php

    I posted this in the ‘Themes and Templates’ forum here but think I may have been in the wrong forum.

    I’ve figured out most of what I was trying to do in that post, but I’m having difficulty finding out how to echo the slug of the current post category.

    I have some default text.. e.g. “About | More from this category” and want to link them to different pages based on each category’s slug.. e.g. https://example.com/about/slug

    I should mention that this is a custom post type so the taxonomy i’m looking for is download_category

  • You may be able to use the get_category_by_slug() and get_category_link() functions.

    Thanks vtxyzzy.. The problem is that it’s a custom post type, so all the get_category commands don’t work. Apparently they only work with the regular blog posts.

    The get_term commands are what I think I’m supposed to be using, but I still can’t get it to spit out a ‘slug’

    The functions that take a post id should work on custom post types. For example, 585 is the ID of a CPT post, and this works for me:

    $id = 585;
$cats = get_the_category($id);
echo "The slug is {$cats[0]->slug}<br />";

    I ended up working it out. I used this piece of code here:

    <?php
	//Get campaign category name and slug
        $terms = get_the_terms( $post->ID, 'download_category' );
            if ( $terms && ! is_wp_error( $terms ) ) :
                $categories = array();
                $slugs = array();
                foreach ( $terms as $term ) {
                  $categories[] = $term->name;
                  $slugs[] =  $term->slug;
                }
                $category = join( " / ", $categories );
                $slug = join( " / ", $slugs );
            endif;
?>

    I echoed the above like this:

    <a href="/about/<? echo $slug ?>">About</a>
<a href="/campaigns/category/<? echo $slug ?>">More from <? echo $category ?></a>

    NOTE: This will only work when the post is assigned to one category.
