Breadcrumb path for Post Archive Page

Hello Marc @mdxfr,

Could you clarify what you mean by “an archive page for posts”? Also, is “My cat” a post tag or a category? Please provide more details.

Thanks, Phi

hello,

My cat = just a post category page

an archive page for posts = the page that displays the post category (is_archive). Often we it dispays a query loop of posts for the given category in it + the category description.

In FSE, the breadcrumb has to be set in the Post Archive Template.

@mdxfr Here is the code snippet for all single, category, post tag contexts:

// Prepend the blog page.
function breadcrumb_block_prepend_blog( $breadcrumbs_instance ) {
	$blog_id = get_option( 'page_for_posts' );
	if ( $blog_id ) {
		$breadcrumbs_instance->add_item( get_the_title( $blog_id ), get_permalink( $blog_id ) );
	}
}

// Single post context.
add_action(
	'breadcrumb_block_single_prepend',
	function ( $post, $breadcrumbs_instance ) {
		if ( 'post' === $post->post_type ) {
			breadcrumb_block_prepend_blog( $breadcrumbs_instance );
		}
	},
	10,
	2
);

// Category context.
add_filter(
	'breadcrumb_block_get_item',
	function ( $item, $context, $breadcrumbs_instance ) {
		if ( ! $context || 'term' !== ( $context['type'] ?? '' ) ) {
			return $item;
		}

		if ( 'category' === $context['object']->taxonomy && ! intval( $this_category->parent ) ) {
			breadcrumb_block_prepend_blog( $breadcrumbs_instance );
		}

		return $item;
	},
	10,
	3
);

// Post tag context.

add_filter(
	'breadcrumb_block_get_item',
	function ( $item, $context, $breadcrumbs_instance ) {
		if ( ! $context || 'term' !== ( $context['type'] ?? '' ) ) {
			return $item;
		}

		if ( 'post_tag' === $context['object']->taxonomy ) {
			breadcrumb_block_prepend_blog( $breadcrumbs_instance );
		}

		return $item;
	},
	10,
	3
);

I’ve not tested it yet, please let me know if it works for you.

Hello,

i’ve tweaked a little bit :

• since the “Single post context.” part adds twice the blog root in a single post, i’ve deactivated this part.
  • seems the category context covers already the case with if the IF statements
• in my context, the blog root page is a Page, so i’ve hard set the blog_id

just for anyone looking for this, now the breadcrumbs are

• home / blog /// blog home
• home / blog / cat /// blog cat archive page
• home / blog / cat / mypost /// blog single post (considering a post is a related to a solely single category, i did not test in case of multiple categories associated to a single post)

thank Phi !

@mdxfr You’re welcome. I’m glad to hear it works.

Phi.
