我无法按类别ID提取WooCommerce产品 [英] I can't fetch WooCommerce products by category id

问题描述

我正尝试通过以下方式按类别ID提取产品：

I am trying to fetch products by category ID this way:

<?php

$args = array(
    'posts_per_page' => 20,
    'taxonomy' => 'product_cat',
    'post_type' => 'product',
    'post_status' => 'publish',
    'cat' => $cat_id
); 

$query = new WP_Query($args);

$posts = get_posts($args);
var_dump($posts);

?>

$ cat_id 变量包含正确的类别ID。我已经检查过了产品被添加到正确的类别。

The $cat_id variable contains the correct category ID. I've checked it. Products are added to correct categories.

问题是，每当我 var_dump $ posts 变量，我得到一个空数组。从参数中删除猫 关键字后，我可以毫无问题地获取所有类别的产品。唯一的问题是'cat'关键字。

The problem is, whenever I var_dump the $posts variable I get an empty array. As soon as I remove the 'cat' keyword from the arguments I can fetch products from all categories with no problems. The only problem is the 'cat' keyword.

我做错了吗？

推荐答案

您可以尝试以下方法：

$args = array(
    'posts_per_page' => 20,
    'post_type' => 'product',
    'post_status' => 'publish',
    'tax_query' = array(
         'taxonomy' => 'product_cat',
         'field'    => 'term_id',
         'term'     =>  $cat_id
     )
);
$query = new WP_Query($args);
var_dump($query);

我还没有测试过，但是应该可以。

I haven't test it, but it should work.
