php - Woocommerce，使用 wp 查询按类别获取产品

Question

我尝试了很多方法，但我无法显示具有类别名称或 id 的产品

                  $args = array(
                       'post_type'             => 'product',
                       'post_status'           => 'publish',
                       'ignore_sticky_posts'   => 1,
                       'cat'                   => 40,
                       'posts_per_page'        => '12',
                   );

                  $loop = new WP_Query( $args );

试试这个例子，

因此，给定一个 ID 为 26 的类别，以下代码将返回它的产品 (WooCommerce 3+):

 $args = array(
    'post_type'             => 'product',
    'post_status'           => 'publish',
    'ignore_sticky_posts'   => 1,
    'posts_per_page'        => '12',
    'tax_query'             => array(
        array(
            'taxonomy'      => 'product_cat',
            'field' => 'term_id', //This is optional, as it defaults to 'term_id'
            'terms'         => 26,
            'operator'      => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
        ),
        array(
            'taxonomy'      => 'product_visibility',
            'field'         => 'slug',
            'terms'         => 'exclude-from-catalog', // Possibly 'exclude-from-search' too
            'operator'      => 'NOT IN'
        )
    )
);
$products = new WP_Query($args);
var_dump($products);
