如何为每个产品类别选择最后5种产品？我试着从每个类别中选择最后5种产品，并添加标签；新建；。我看到这是WP\\u查询，但我没有找到有帮助的参数。我有这个代码，可以很好地添加标记；“新建”；对于超过30天的产品。提前谢谢你，我真的很感激。

function display_new_loop_woocommerce() {
global $product;

$datetime_now = new WC_DateTime();
$timestamp_now = $datetime_now->getTimestamp();


$args = array(
\'post_type\' => \'product\', // your product post type
\'posts_per_page\' => - 1,
);

$posts = get_posts($args);

foreach ($posts as $post):
setup_postdata($post);

$product = new WC_Product($post->ID);

$datetime_created = $product->get_date_created();
$timestamp_created = $datetime_created->getTimestamp();

$time_delta = $timestamp_now - $timestamp_created; 
$sixty_days = 30 * 24 * 60 * 60; 


if ( $time_delta < $sixty_days ) {
    if( ! has_term( \'\', \'product_tag\', $post->ID ) ) :
        wp_set_object_terms($post->ID, array(\'nou\'), \'product_tag\');
    endif;   
} else {
    if( has_term( \'\', \'product_tag\', $post->ID ) ) :
        wp_remove_object_terms($post->ID, array(\'nou\'), \'product_tag\');
    endif;   
}

wp_reset_postdata();
endforeach;
}
