  这可以通过自定义函数在其中设置“父”产品类别slug：

  function get_product_subcategories_list( $category_slug ){
      $terms_html = array();
      $taxonomy = 'product_cat';
      // Get the product category (parent) WP_Term object
      $parent = get_term_by( 'slug', $category_slug, $taxonomy );
      // Get an array of the subcategories IDs (children IDs)
      $children_ids = get_term_children( $parent->term_id, $taxonomy );
  
      // Loop through each children IDs
      foreach($children_ids as $children_id){
          $term = get_term( $children_id, $taxonomy ); // WP_Term object
          $term_link = get_term_link( $term, $taxonomy ); // The term link
          if ( is_wp_error( $term_link ) ) $term_link = '';
          // Set in an array the html formated subcategory name/link
          $terms_html[] = '<a href="' . esc_url( $term_link ) . '" rel="tag" class="' . $term->slug . '">' . $term->name . '</a>';
      }
      return '<span class="subcategories-' . $category_slug . '">' . implode( ', ', $terms_html ) . '</span>';
  }
  

  代码位于活动子主题（或活动主题）的function.php文件中 .

  经过测试和工作 .

  This is the code for get subcategory of given category:

  $categories = get_the_terms( get_the_ID(), 'product_cat' ); 
  
   //For checking category exit or not
  
   if ( $categories && ! is_wp_error( $category ) ) : 
  
  
     foreach($categories as $category) :
        // get the children (if any) of the current cat
        $children = get_categories( array ('taxonomy' => 'product_cat', 'parent' => $category->term_id ));
  
      if ( count($children) == 0 ) {
         // if no children, then echo the category name.
          echo $category->name;
      }
    endforeach;
  
   endif;
