I have been able to get a simple file upload to work but would like to be able to download the files that have been uploaded. Any ideas on how to do this? I have looked but haven't found any info... Thanks.

Hi,
Once the files are uploaded, the path to each file is stored in the database field that you specified as "Control Source" for your FileUpload component.
You can create a link (using the Link component from the Toolbox) and use the same "Control Source". Then the link will point to the file and users can click on it to download the file.

This is the code I use:
<?php
define("RelativePath", ".");
include(RelativePath . "/Common.php");
$file = CCGetParam("file", "");
$size = CCGetParam("size", "");
$doc_id = CCGetParam("doc_id", "");
$file_name = substr (strrchr ($file, "/"), 1);
$file_name = substr (strstr ($file_name, "."), 1);
//$size = filesize($file);
header("Content-length: $size");
header("Content-Type: application/unknown");
header("Content-Disposition: attachment; filename=\"$file_name\"");
header("Content-Transfer-Encoding: binary");
readfile($file);
$db = new clsDBAdelphosweb();
$SQL = "UPDATE web_docs SET cnt = cnt + 1 WHERE doc_id=" . $doc_id;
$db->query($SQL);
$db->close();
exit();
?>
I put this in one file and download.php
Then I call the file like this:
$web_docs->Link1->Page = "download.php?file=/home/3829249850/www/web/docs/"
.. $web_docs->FileUpload1->Value . "&size=" .
$web_docs->FileUpload1->GetFileSize() . "&doc_id=" .
$web_docs->doc_id->GetValue();
Hope this helps

In using Peterr' slink suggestion above, I cannot get the link to download the file from the proper folder. Th efile folder is specified in the File Upload component, however. file is saved in the database without the file folder.
Soooo the question is how do I get the link to retrieve the uploaded file? I have tried to add the file folder in the Befroe show event, however, i am not suceesful.
Any ideas are appreciated.

Just another spin on this question:
How do you view the uploaded file (instead of linking and downloading it). Assuming it is plain text or HTML file (not an image).

JCF, what would happen if I did this kind of thing to your site?
download.php?file=/etc/password
download.php?file=/etc/shadow

the risk can be eliminated by using file name only ...
$file = CCGetParam("file", "");
as
$file="/downloads/".CCGetParam("file", "");
if(file_exists($file))
{
........
}

You'll need to prefix the Control Source value (from Peterr's posting)
with the value you used for the File Folder property of the File Upload.

It would be good and most valuable if you would show how to do this prefixing, exactly. Because of your help, I know what to do, but not How to do it.
And CodeCharge, this needs to be documented properly within the context and content of the excellent Upload Overview in the help. One almost never wants to upload with out being able to download In future versions, the upload and download capability should, in my opine be combined with download being transparent and built in with the upload. Putting navigators on the file location fields of the upload file object would be most helpful too. 
Thanks klw, for stepping in and helping.
