我已按照此链接中使用 DB 的说明进行操作：https ://github.com/blueimp/jQuery-File-Upload/wiki/Working-with-databases 。我检查了一切，尤其是连接设置。他们是正确的。但它一直显示“错误{}”。我试图在我的服务器的日志文件和调试工具上找到线索，但没有运气。
这是截图：
索引.php
error_reporting(E_ALL | E_STRICT);
$sid=$_GET['sid'];
$caption=$_GET['title'];
$view="0";
require('UploadHandler.php');
$upload_handler = new UploadHandler();
此外，我还附上了“UploadHandler.php”，看看是否有任何隐藏的错误。

我可以在没有数据库的情况下上传图片，但在这种情况下会淹没我几个小时。请让我离开这里。
