GREAT plugin, fantastic codebase: super clean & TESTED?! FTW! Only downside is no schematagging out of the box :/. This is a pivotal SEO feature and I think this would greatly boost interest in your plugin. Info: https://developers.google.com/search/docs/data-types/breadcrumbs#guidelines Result should look like: <ol ="http://schema.org/BreadcrumbList"> <li ="itemListElement" ="http://schema.org/ListItem"> <a ="http://schema.org/WebPage" ="item" href="link.html"> <span ="name">Crumb 1</span> </a> <meta ="position" content="1" /> / </li> <li ="itemListElement" ="http://schema.org/ListItem"> <a ="http://schema.org/WebPage" ="item" href="link2.html"> <span ="name">Crumb 2</span> </a> <meta ="position" content="2" /> </li> </ol> Here’s how I’ve shimmed it in: <?php $breadcrumbs = new Carbon_Breadcrumb_Trail(array( 'glue' => ' / ', 'link_before' => '<li ="itemListElement" ="http://schema.org/ListItem">', 'link_after' => '</li>', 'wrapper_before' => '<ol class="breadcrumbs" ="http://schema.org/BreadcrumbList">', 'wrapper_after' => '</ol>', 'title_before' => '<span ="name">', 'title_after' => '</span>', )); $breadcrumbs->setup(); echo $breadcrumbs->render(true); // WP_KSES strips , , etc, so bypassing!!! add_filter('carbon_breadcrumbs_item_attributes', _'breadcrumb_schematags', 10, 2); function breadcrumb_schematags($attributes, $item) { if (!is_array($attributes)) $attributes = array(); $attributes[''] = null; $attributes[''] = 'http://schema.org/WebPage'; $attributes[''] = 'item'; return $attributes; } add_filter('carbon_breadcrumbs_item_output', 'breadcrumb_item_position', 10, 5); function breadcrumb_item_position($item_output, $item, $trail, $trail_renderer, $index){ // Add Position $n = strrpos($item_output, '</li>'); $item_output = substr($item_output, 0, $n) . '<meta ="position" content="'. $index .'" />' . substr($item_output, $n); return $item_output; }

see how.

This remains the best breadcrumbs plugin I’ve used. In addition to its rich customization options, it provides developers with various easy ways to extend it.

This plugin has saved me quite some time. Thanks to the numerous filters, you can adjust everything. Respect <3
