php - 输入文件的表单编辑

Question

我正在制作编辑数据表单。然后在编辑表单中，有3种输入文件类型(图像)。所以问题是，当我更新其中一种输入文件类型的 1 个文件时，另一种输入文件类型也会更新并取消链接数据库中以前的数据，因此该列为空。

所以我想制作这个编辑表单，当我更新1个文件时，另一个文件不会改变。仅应更改正在更新的一项，而另一项应保持不变。

所有帮助和答案将不胜感激。谢谢 这是 edithotel.php

Answer 1

您需要检查 $nama_file1 和其他内容是否为空。

if($gambar1 != 'kosong' && !empty($nama_file1)){
...
}
