Downloading a file with a different name to the st

问题:

Is it possible to let your user download a file with a different name?

For example, there is a file called "4324ffsd34.jpg". I want people to download it via download.php, with a different name (like "filetodownload.jpg"), without renaming the original file.

回答1:

Sure, use a Content-disposition header

header('Content-Disposition: attachment; filename="filetodownload.jpg"');

if you wish to provide a default filename, but not automatic download, this seems to work.

header('Content-Disposition: filename="filetodownload.jpg"');

Sure you can, just try something like this:

$original_filename = '4324ffsd34.jpg';
$new_filename = 'my_new_filename_is_detailled.jpg';

// headers to send your file
header("Content-Type: application/jpeg");
header("Content-Length: " . filesize($original_filename));
header('Content-Disposition: attachment; filename="' . $new_filename . '"');

// upload the file to the user and quit
readfile($original_filename);
exit;

Hope it helps!

There is also another way if you are using html5

<a href="link/to/my/file/with/a/name/i/dont/like.jpg" download="MyFile.jpg">Download</a>

Cheers :3

Nothing wrong with the above but I had to add:

ob_clean();
flush();

before readfile

otherwise I can not open the download jpg/png file

<a href="4324ffsd34.jpg" download="filetodownload">Download</a>
