  如果我理解这是正确的方法，首先你需要在word press admin菜单空白菜单中创建菜单 . 现在转到function.php文件（主题文件）中添加以下代码 .

  你可以从这个功能获得产品cateogorty列表，

  function get_product_terms( $term_id ) {
  
          $html = '';
  
          $args = array( 'hide_empty' => 0, 'parent' => $term_id );
  
          $terms = get_terms('product_cat', $args);
  
          foreach ($terms as $term) {
  
              $html .= '<li';
  
              if( $term_id == 0 ) {
  
                  $html .= ' class="top_li"';
  
              }
  
              $html .= '><a href="'.get_term_link($term->slug, 'product_cat').'">' . $term->name . '</a>';    
  
              if( $list = get_product_terms( $term->term_id )) {
  
                  $html .= '<ul class="second_level">'.$list.'</ul>';
  
              }
  
              $html .= '</li>';
  
          }
  
          return $html;
  
      }
  

  您可以使用此功能将产品类别添加到菜单，

  // Filter wp_nav_menu() to add additional links and other output
  function new_nav_menu_items($items) {
      // Woo function
  
      /*//product_cat
      $terms = get_terms( 'product_cat', $args );
      print_r($terms);*/
      if( $list = get_product_terms( 0 )) {
  
  
  
      $menu1link = '<li class="home"><a href="' . home_url( '/' ) . '">' . __($list) . '</a></li>';
      $homelink = '<li class="home"><a href="' . home_url( '/' ) . '">' . __('Home') . '</a></li>';
      // add the home link to the end of the menu
      $items = $items . $homelink;
      $items = $items .$menu1link;
      }
      return $items;
  
  }
  add_filter( 'wp_nav_menu_items', 'new_nav_menu_items' );

  在单个产品页面上显示类别图像

  $terms = get_the_terms( $post->ID, 'product_cat' );
  foreach ( $terms as $term ){
    $category_name = $term->name;
    $category_thumbnail = get_woocommerce_term_meta($term->term_id, 'thumbnail_id', true);
    $image = wp_get_attachment_url($category_thumbnail);
    echo '<img class="absolute category-image" src="'.$image.'">';
  }

  <?php
                   $terms = get_the_terms( $post->ID, 'product-category' );
  
                  foreach ( $terms as $term ){
                 $category_name = $term->name;
               $category_thumbnail = get_woocommerce_term_meta($term->term_id, 'thumbnail_id', true);
              $image = wp_get_attachment_url($category_thumbnail);
                    ?>
              <div class="col-md-4 col-sm-4 col-xs-12">
                  <a href="">
                  <div class="service wow slideInLeft">
                      <div class="icon"><img src="<?php bloginfo('template_url'); ?>/images/buiding/icon18.png"></div>
                      <h4><?php echo $category_name; ?></h4>
                  </div>
                  </a>
              </div>
  
              <?php }   ?>
  

  我添加了这个代码 . 但是没有工作 . 它显示如下错误“警告：在C：\ xampp \ htdocs \ Working-files \ rajab \ wp-content \ themes \ rajab \ page-中为foreach（）提供的参数无效模板\ building.php”
