Breadcrumb Block

This is a single-block plugin for the breadcrumb trail. It’s simple, lightweight, SEO-friendly, and WooCommerce compatibility. It also includes some simple separator icons. It works everywhere: Page Editor, Site Editor, and template files.

How to customize the breadcrumb

1. How to change/remove an item?

   add_filter( 'breadcrumb_block_get_item', function ( $item_args, $context, $breadcrumbs_instance ) {
     // Ignore items without context.
     if ( ! $context || ! ( $context['object'] ?? false ) ) {
       return $item_args;
     }
   
     // Eg: remove a term.
     if ( 'term' === ( $context['type'] ?? '' ) && 'term-slug' === $context['object']->slug ) {
       return false;
     }
   
     // Eg: Change the title of a page.
     if ( 'page' === ( $context['type'] ?? '' ) && page_id_to_change === $context['object']->ID ) {
       $item_args[0] = 'Make it shorter';
     }
   
     return $item_args;
   }, 10, 3 );
   

   $item_args is a 3-item array: [$item_label, $item_link, $item_attrs]
   $context is an associative array: ['type' => 'item type', 'object' => 'item object']. type can be one of the following values: front_page, home, shop, page, post, single, term, taxonomy, post_type_archive, search, 404, paged, author, date_year, date_month, date_day, attachment.

2. How to change the markup of the block?

   add_filter( 'breadcrumb_block_get_breadcrumb_trail', function ( $markup, $args, $breadcrumbs_instance ) {
     return $markup;
   }, 10, 3 );
   

3. How to add or remove the items from the breadcrumb trail?

   add_filter( 'breadcrumb_block_get_items', function ( $items, $breadcrumbs_instance ) {
     return $items;
   }, 10, 2 );
   

4. How to use a custom separator for the breadcrumb trail?

   add_filter( 'breadcrumb_block_get_args', function ( $args ) {
     // For example, change separator.
     $args['separator'] = '<svg xmlns="http://www.w3.org/2000/svg" fill="currentColor" width="1em" height="1em" viewBox="0 0 16 16"><path fill-rule="evenodd" d="M3.646 1.646a.5.5 0 0 1 .708 0l6 6a.5.5 0 0 1 0 .708l-6 6a.5.5 0 0 1-.708-.708L9.293 8 3.646 2.354a.5.5 0 0 1 0-.708z"/><path fill-rule="evenodd" d="M7.646 1.646a.5.5 0 0 1 .708 0l6 6a.5.5 0 0 1 0 .708l-6 6a.5.5 0 0 1-.708-.708L13.293 8 7.646 2.354a.5.5 0 0 1 0-.708z"/></svg>';
     return $args;
   } );
   

   The custom separator should be an inline SVG. To make sure it displays properly, it should have three attributes: width, height, and fill. The values of these attributes should be as follows: fill="currentColor" width="1em" height="1em".
   Using this hook, you can customize other attributes such as container, before, after, list_tag, item_tag, item_before, item_after, separator.

5. How to prepend the blog page to all single posts?

   add_action( 'breadcrumb_block_single_prepend', function ( $post, $breadcrumbs_instance ) {
     if ( 'post' === $post->post_type ) {
       $blog_id = get_option( 'page_for_posts');
       if ( $blog_id ) {
         $breadcrumbs_instance->add_item( get_the_title( $blog_id ), get_permalink( $blog_id ) );
       }
     }
   }, 10, 2 );
