How To Remove Product Name From Breadcrumbs in Woocommerce

If you need to remove last element from breadcrumbs, you must:

1. In the folder with your theme, create a folders “woocommerce/global”

wp-content/themes/your-theme/woocommerce/global

2. Then copy ffrom Woocommerce plugin (or just create) file “breadcrumbs.php”

wp-content/themes/your-theme/woocommerce/global/breadcrumbs.php

3. Replace (paste) the next code in breadcrumbs.php:

<?php

if ( ! defined( 'ABSPATH' ) ) {
   exit;
}

if ( ! empty( $breadcrumb ) ) {

   echo $wrap_before;

   foreach ( $breadcrumb as $key => $crumb ) {

      echo $before;

      if ( ! empty( $crumb[1] ) && sizeof( $breadcrumb ) !== $key + 1 ) {
         echo '<a href="' . esc_url( $crumb[1] ) . '">' . esc_html( $crumb[0] ) . '</a>';
      } else {
            if(!is_singular()){
                echo esc_html( $crumb[0] );
            }
      }

      echo $after;
        if(sizeof( $breadcrumb ) -2 == $key && (is_singular())){
            continue;
        }

      if ( sizeof( $breadcrumb ) !== $key + 1 ) {
         echo $delimiter;
      }
   }

   echo $wrap_after;

}

Last thing, you need to remove the last item in breadcrumbs from the micro data markup. This code placed in functions.php will help:

add_filter('woocommerce_structured_data_breadcrumblist', 'delete_last_item_from_structured_data', 10, 1);

function delete_last_item_from_structured_data($markup){
    if(is_singular()){
        array_pop($markup['itemListElement']);
    }
    return $markup;
}
