检查文件类型的最高级别条件可能由于可能的输入错误而永远不会触发：$\u FILES[“new\u image”][“type”]
应该是：$\u文件['image']['type']
您还应该考虑为数据库操作捕获异常：
mysqli_query(..) or trigger_error(mysqli_error($dbc));
你收到错误消息了吗？@DanielA.White我收到一个解析错误，但除了第12行没有其他信息我试过了，但我在第12行收到了一个解析错误，但这就是它提供的所有信息gives@RyanKelly仔细检查。。您有一个额外的“'）：：（$_文件[“图像”][“类型”]=“图像/pjpeg”））
