Laravel下载未知类型的文件

Question

I am using Laravel 4. I allow users to upload a file, which is programmatically renamed with some number and stored. I also allow them to download the files, though I am supposed to rename their file from some funny number to their name, and download it.

My problem is, how can I change filename just before its downloaded?

My code:

return Response::download($pathToFile, $name);

When I do that, the file is downloaded with unknown format.

Answer 1

The second $name parameter, needs to include the full filename (including the file extension). The download method does not automatically detect the extension from the file path and append it to the name, so that needs to be done manually. Something like this will work:

return Response::download(
    $pathToFile,
    $name . '.' . pathinfo($pathToFile, PATHINFO_EXTENSION)
);
