Recently I was asked to implement a custom breadcrumb trail for all posts in 5 different custom post types on a site using the Breadcrumb NavXT plugin. The posts belonged to different categories, were in different post types and all suffered from a messy breadcrumb trail. It was desired that all of the posts had a consistent breadcrumb trail, which was:
Home > Knowledge > {{ Post Name }}
Breadcrumb NavXT has an action which runs just after the breadcrumb trail has been built, and I was able to use it to rewrite the breadrcrumb trail to suit my requirements.
| <?php | |
| add_action( 'bcn_after_fill', 'project_rebuild_breadcrumb' ); | |
| /** | |
| * Rebuild the breadcrumb created by Breadcrumb NavXT. | |
| * | |
| * @param bcn_breadcrumb_trail $breadcrumb Instance of the currently active breadcrumb trail. | |
| */ | |
| function project_rebuild_breadcrumbs( $breadcrumb ) { | |
| if ( ! is_singular( [ 'case-studies', 'articles', 'presentations', 'papers-reports', 'creative-portfolio' ] ) ) { | |
| return; | |
| } | |
| // Default breadcrumb template. | |
| $breadcrumb_template = '<span class="breadcrumb-link-wrap" itemprop="itemListElement" itemscope="" itemtype="https://schema.org/ListItem" property="itemListElement" typeof="ListItem"><a itemprop="item" property="item" typeof="WebPage" title="Go to %title%." href="%link%" class="%type%"><span property="name">%htitle%</span></a><meta property="position" content="%position%"></span>'; | |
| /** | |
| * Store the first and last breadcrumbs, we're rebuilding the middle part. | |
| */ | |
| $breadcrumb_root = reset( $breadcrumb->breadcrumbs ); | |
| $breadcrumb_end = end( $breadcrumb->breadcrumbs ); | |
| /** | |
| * Build our custom Knowledge breadcrumb. | |
| */ | |
| $knowledge_page = get_page_by_path( 'knowledge' ); | |
| $breadcrumb_title = __( 'Knowledge', 'project' ); | |
| $breadcrumb_link = get_the_permalink( $knowledge_page->ID ); | |
| $knowledge_item_breadcrumb = new bcn_breadcrumb( $breadcrumb_title, $breadcrumb_template, [], $breadcrumb_link, $knowledge_page->ID ); | |
| /** | |
| * Update the Breadcrumb NavXT object. | |
| */ | |
| $breadcrumb->breadcrumbs = [ | |
| $breadcrumb_root, | |
| $knowledge_item_breadcrumb, | |
| $breadcrumb_end, | |
| ]; | |
| } | |
| } |
