Question

我的编辑页面遇到问题。肯定有一些我想念的地方。

我可以完美地添加和查看我的特色产品，但是一旦我将其中一张图像编辑为另一张图像，其他所有5张图像就会中断，然后在我查看时，它们也会在此处中断。 / p>

这是编辑页面上的样子

这是视图页面上的样子

我要做的就是单独更新每个图像，而不会影响其他图像。

这是我的编辑页面代码

    header("location: welcome.php");

任何帮助将不胜感激，因为我在产品页面上遇到了相同的问题，即产品图片和pdf链接执行相同的操作，我必须同时更新两者，如果我更新一个或另一个会破坏一个或另一个。它让我发疯。

更新图像，但破坏其他图像php mysqli
