Woocommerce 3.9.0的更新

对@ alejandro-restrepo给出的出色答案进行了轻微修改-此版本还从相关产品查询中排除了当前产品，并且是从Woocommerce 3.9.0模板中进行了修改。

将此代码复制到[your-theme]/woocommerce/single-product/related.php

<?php
/**
 * Related Products
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/related.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see         https://docs.woocommerce.com/document/template-structure/
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     3.9.0

  return;

Answer 2

您必须在模板中创建woocommerce-＆gt;单产品文件夹和related.php文件。

然后粘贴此代码。

<?php
/**
 * Related Products
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/related.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see         https://docs.woocommerce.com/document/template-structure/
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     1.6.4

if ( empty( $product ) || ! $product->exists() ) {

if ( ! $related = $product->get_related( $posts_per_page ) ) {

$cats_array = array(0);

Answer 3

为了做到这一点，你的所有产品必须只有一个子类别，如小型，中等..但是，如果你的产品有两个以上是不可能的，我想。

但是有一种简单的方法可以达到你想要的效果，答案是交叉销售的read this

Answer 4

万一你遇到和我一样的问题：

如果您的产品也被分类的父分类，您只需使用高级woocommerce批量编辑插件从您的产品中删除父分类，就大功告成了。享受。

Woocommerce：仅显示来自相同子类别的相关产品
