Wordpress is one best open source application by which a well formed website can be made by beginner or an expert web designer. It is free and easy to use. From my personal experience I like its breadcrumb feature especially “Taxonomy” which gives a professional web design looks to my website. So I would like to share code for Custom Taxonomy Breadcrumbs with you.

Copy below code to your functions.php file:

Note: "$" is used for variable declaration
          "echo()" is used to display content
          "foreach" construct provides a simple way to iterate over arrays and it works only on arrays and objects.

<?php     function postTypeCrumbs($postType, $postTax) {         $term             = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );         $taxonomy         = get_taxonomy($term->taxonomy);         $parents         = get_ancestors( $term->term_id, $postTax );         $parents         = array_reverse($parents);         $archive_link    = get_post_type_archive_link( $postType );         echo '<ul class="ax_crumbs">';         if ($taxonomy)  {             echo '<li><a href="' . $archive_link . '" title="' . $taxonomy->labels->name . '">' . $taxonomy->labels->name . '</a> &raquo; </li>';         }         foreach ( $parents as $parent ) {             $p     = get_term( $parent, $postTax );             echo '<li><a href="' . get_term_link($p->slug, $postTax) . '" title="' . $p->name . '">' . $p->name . '</a> <span>&raquo;</span> </li>';         }         if ($term) {             echo '<li>' . $term->name . '</li>';         }         echo '</ul>';     } ?>

Paste below code wherever you want to display taxonomy.

<?php postTypeCrumbs('post type', 'taxonomy name'); ?>
