我正在做基于 PHP 的数据输入程序，每件事都没有问题（仍在建设中），但有一个问题我找不到解决方案。问题是当数据库没有任何数据时，图像路径不会被注册。
现在我正在使用 uplodify 上传图像文件，同时我也在发送一些数据。数据包含名称、联系方式和描述，这将直接插入到数据库中，我还将上传图像，该图像将保存到文件夹中，名称将保存在数据库中。但是这个过程由两个不同的 PHP 文件处理，一个是 AddPOIPro.PHP，它处理数据添加和 uplodify.php，用于处理文件上传和文件名的更新。
我遇到的第一个问题是 uplodify 不是在与提交的数据相同的行中添加文件名，所以我所做的是获取最后一个 ID 并将其递减一个，并更新在有数据时有效的行，但当他们的没有数据失败。那么我该怎么做才能克服这个问题。以下是我的完整脚本，感谢您的时间。
