如何使用HTML5重命名下载文件？

Question

i have been working on a website which will allow users to upload and download files. The file is renamed on upload and stored on my server. But when it is downloaded, it has to be renamed ie to its original name. Presently i am using the following to do so :

<a href="file link" download="Original name">Download</a>

But the "download" attribute does not work with firefox. Any alternative using javascript or jquery ? I am using php for server side.

Edit:

Thanks for the solution using php. But that is not what i am looking for. I am using a custom file viewer using javascript. On clicking the thumbnail of the file, the viewer is displayed. An AJAX request is sent to get the link to the file. The response (the link) is used to display the file, also is added to the tag for download. A php solution would mean a page reload on every request, which i want to avoid. So any javascript or jquery solutions ?

Answer 1

在服务器上使用header("Content-Disposition: attachment; filename='Original name'")

Answer 2

Try Below Code

    header('Content-Disposition: attachment; filename='.basename('newfilename.txt'));
    header('Content-Transfer-Encoding: binary');
    header('Content-Length: ' . filesize('filename.txt'));
    ob_clean();
    flush();
    readfile('filename.txt');
