如何使用wp_insert_post上传多张图片

$post_data = array(
   'post_title'    => '标题',
   'post_content'  => '内容',
   'post_status'   => 'publish',
   'post_author'   => 1,
   'post_type'     => 'post',
);

$post_id = wp_insert_post($post_data);

$image_urls = array(
   'https://example.com/image1.jpg',
   'https://example.com/image2.jpg',
   'https://example.com/image3.jpg',
);

foreach ($image_urls as $image_url) {
   $attachment_id = media_sideload_image($image_url, $post_id);
   if (!is_wp_error($attachment_id)) {
      // 将附件ID添加到帖子或页面的附件列表中
      update_post_meta($post_id, '_thumbnail_id', $attachment_id);
   }
}
