PHP怎么上传图片路径,怎么获取图片路径?

得知以下代码中图片保存的的路径是./upload/. 我也知道怎么把图片的保存路径post到数据库,但是我就是不知道PHP的前端怎么获取./upload/下的图片,因为图片的文件名是随机改过的不是固定的,那我前端怎么获取图片名称啊? 还有我前端提交的是哪几张图片,怎么获取? 求PHP大神教教我, 万分感谢,急用!

if (isset($_REQUEST["md5"]) && array_search($_REQUEST["md5"], $md5File ) !== FALSE ) {

}

$filePath = $targetDir . DIRECTORY_SEPARATOR . $fileName;
$uploadPath = $uploadDir . DIRECTORY_SEPARATOR . $fileName;

Answer 1

$filePath 应该是上传的临时文件吧，然后将$filePath，这个文件移动到 $uploadPath，$uploadPath，应该就 你已经上传的图片的路径！包含图片文件的名称。

追问

我只会post路径，怎么post变量啊？比如$uploadPath.
