在wordpress/woocomerce上程序化添加产品缩略图和图像

function programmatically_add_product_images($post_id) {
    // 设置缩略图
    $thumbnail_id = get_post_thumbnail_id($post_id);
    set_post_thumbnail($post_id, $thumbnail_id);

    // 添加其他图像
    $gallery_images = array(); // 用于存储其他图像的ID
    // 添加其他图像的URL到$gallery_images数组中
    $gallery_images[] = 'http://example.com/image1.jpg';
    $gallery_images[] = 'http://example.com/image2.jpg';

    // 将其他图像添加到产品的图像库中
    foreach ($gallery_images as $image_url) {
        $image_id = media_sideload_image($image_url, $post_id);
        if (!is_wp_error($image_id)) {
            $gallery_images[] = $image_id;
        }
    }

    // 更新产品的图像库
    update_post_meta($post_id, '_product_image_gallery', implode(',', $gallery_images));
