I have a breadcrumb displayed on all content types (pages, posts, homepage etc.) - beside of category. What is the way to add category to content types, where breadcrumb is showing?

This is the breadcrumb code from my functions.php:

function asap_breadcrumbs_pages($post,$schema)
{

    if ( ! get_theme_mod('asap_hide_breadcrumb_page') && ! get_post_meta( get_the_ID(), 'hide_breadcrumbs', true ) )
    {
        
        $url_pillar_page = get_post_meta(get_the_ID() , 'single_bc_url_pillar_page', true);

        $text_pillar_page = get_post_meta(get_the_ID() , 'single_bc_text_pillar_page', true);

        $post_title = get_post_meta(get_the_ID() , 'single_bc_text', true) ? : get_the_title();

        $label = get_theme_mod('asap_breadcrumb_text') ? : get_bloginfo('name');

        if ($schema)
        {
            $format = '<li itemprop="itemListElement" itemscope itemtype=";><a href="%s" title="%s" itemprop="item"><span itemprop="name">%s</span></a><meta itemprop="position" content="%s"></li>';
        }
        else
        {
            $format = '<li><a href="%s" title="%s"><span>%s</span></a></li>';
        }

        if ($url_pillar_page && $text_pillar_page)
        {
            $count = 3;
        }
        else
        {
            $anc = array_map('get_post', array_reverse((array)get_post_ancestors($post)));

            $count = count($anc);

            $count = $count + 2;

            $links = array_map('get_permalink', $anc);

        }

        if ($schema)
        {
            printf('<div role="navigation" aria-label="Breadcrumbs" class="breadcrumb-trail breadcrumbs" itemprop="breadcrumb">');

            printf('<ul class="breadcrumb" itemscope itemtype=";>');

            printf('<meta name="numberOfItems" content="' . $count . '">');

            printf('<meta name="itemListOrder" content="Ascending">');

            printf('<li itemprop="itemListElement" itemscope itemtype=";><a href="%s" itemprop="item"><span itemprop="name">' . $label . '</span></a><meta itemprop="position" content="1"></li>', esc_url(home_url()));
        }
        else
        {
            printf('<div class="breadcrumb-trail breadcrumbs">');

            printf('<ul class="breadcrumb">');

            printf('<li><a href="%s"><span>' . $label . '</span></a></li>', esc_url(home_url()));
        }

        $meta = 2;

        if ($url_pillar_page && $text_pillar_page)
        {
            printf($format, $url_pillar_page, $text_pillar_page, $text_pillar_page, $meta);

            $meta = $meta + 1;
        }
        else
        {
            foreach ($anc as $i => $apost)
            {
                
                $title = get_post_meta( $apost->ID , 'single_bc_text', true);
            
                if ( ! $title ) {

                $title = apply_filters('the_title', $apost->post_title);
                    
                }

                printf($format, $links[$i], esc_attr($title) , esc_html($title) , $meta);

                $meta = $meta + 1;
            }

        }

        if ($schema)
        {
            echo '<li itemprop="itemListElement" itemscope itemtype=";><span itemprop="name">' . $post_title . '</span><meta itemprop="position" content="' . $meta . '"></li>';
        }
        else
        {
            echo '<li><span>' . $post_title . '</span></li>';
        }

        printf('</ul>');

If you're dealing with the default "Category" taxonomy and the post post type, then you can get the post's attached category terms with get_the_category().

$categories = has_category( $post ) ? get_the_category( $post ) : array();

The has_category() check is there just to fend off other post type posts.

get_the_category() gives you an array of categories as WP_Terms. They are probably not in any particular order and there might terms from different hierarchy levels in the list. So for example use the first term or conjure up some logic to order the terms in the desired order, before rendering them all.

To get the category link you can use get_category_link(). The category name can be read from the WP_Term object and used as the anchor text.

$category_link = $categories
    ? sprintf(
        '<a href="%s">%s</a>',
        esc_url( get_category_link( $categories[0] ) ),
        esc_html( $categories[0]->name )
    )
    : '';

If you have other taxonomies and post types, then use has_term(), get_the_terms(), and get_term_link().
