Question

我想在单个产品页面中显示与子类别相关的相关产品，而不是父类别。现在我有大约100种产品，其中大约90种属于同一父类别（它们也属于其他父类别）。因此，在单个产品页面中，您可以看到几乎任何随机产品，因为这个大的父类别。有没有办法限制这个？我做了一个研究，我得到了一些关于woocommerce版本1.6的答案......现在我使用3.2.6，所以它没有用。

Answer 1

你可以使用这个代码或适合你的情况，希望它的工作.. 将它添加到你的function.php

add_filter( 'woocommerce_product_related_posts', 'woocommerce_get_direct_related_products' );

function woocommerce_get_direct_related_products() {
    global $woocommerce, $product;

    // Related products are found from category
    $cats_array = array(0);

    // Get categories
    $terms = wp_get_post_terms( $product->id, 'product_cat' );

    //Select only the category which doesn't have any children
    foreach ( $terms as $term ) {
        $children = get_term_children( $term->term_id, 'product_cat' );
        if ( !sizeof( $children ) )
            $cats_array[] = $term->term_id;
    }

    // Don't bother if none are set
    if ( sizeof( $cats_array ) == 1 ) return array();

    // Meta query
    $meta_query = array();
    $meta_query[] = $woocommerce->query->visibility_meta_query();
    $meta_query[] = $woocommerce->query->stock_status_meta_query();

    $limit = 5;

    // Get the posts
    return array(
        'orderby'       => 'rand',
        'posts_per_page'=> $limit,
        'post_type'     => 'product',
        'fields'        => 'ids',
        'meta_query'    => $meta_query,
        'tax_query'     => array(
            array(
                'taxonomy'  => 'product_cat',
                'field'     => 'id',
                'terms'     => $cats_array
            )
        )
    );
}

这可能是Woocommerce: Only show related products from same subcategory

的副本

另一种解决方法是覆盖模板文件[your-theme]/woocommerce/single-product/related.php

以下内容已更新，可与Woocommerce 3.x一起使用

<?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

global $product, $woocommerce_loop;

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

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

// Get ID of current product, to exclude it from the related products query
$current_product_id = $product->get_id();

$cats_array = array(0);

// get categories
$terms = wp_get_post_terms( $product->id, 'product_cat' );

foreach ( $terms as $term ) {
  $children = get_term_children( $term->term_id, 'product_cat' );
