Question

嘿伙计们，所以我已经制作了一个系统，根据id，管理面板上的任何图片上传都会保存在特定的文件夹中！但是当我做了一些更改时，我的php网站没有保存带有id名称的图片，也没有存储超过1张图片。

您无法使用相同的连接在mysqli和mysql之间切换。（注意mysql_insert_id）。

将mysql_insert_id更改为mysqli_insert_id($conn)。

另外：将所有mysqli_real_escape_string($_POST...)更改为mysqli_real_escape_string($conn, $_POST...)（... = POST名称）并将mysql_num_rows更改为mysqli_num_rows($conn, $sql)。

查看php.net网站，了解mysql和mysqli之间的变化概述。
