We have successfully created code for uploading files to a site and
moving that file to an A4D-aware directory. Now we want to download
it back to the user as a link. Can someone give me some sample code
to do this?
I assume that we need to copy the file into a variable and send that
to the browser, but I'm not sure how to get started.
I've done this with PHP by using:
$dir="download/files/";
$filename = $_REQUEST["file"];
$file=$dir.$filename;
// Test to ensure that the file exists.
if(!file_exists($file)) die("I'm sorry, the file doesn't seem to
exist.");
// Extract the type of file which will be sent to the browser
as a header
$type = filetype($file);
$size = filesize($file);
ob_clean(); // clean the output buffer
of any crap
// Send file headers
// header("Content-type: $type");
header("Content-Type: application/force-download;
name=\"$filename\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: $size");
header("Content-Disposition: attachment;
filename=\"$filename\"");
header("Expires: 0");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
// Send the file contents.
set_time_limit(0);
readfile($file);
exit;
But in a4D, I can't seem to get the file into a variable correctly.
Thanks!
