Ave, I created a multi-user File Management program written in PHP with mySQL backend. Basically it allows registered users to upload files to their or other users accounts, and allows them to download files. I use the force-download for my download process. Here's the problem. When someone clicks on the download link for a file, the Save Dialog box opens, giving user the choice to either "OPEN" the file or "SAVE" the file to a particular location. The problem is.. If you SAVE the file to any location.. It works fine. You can go and open the file from that location. However, if you choose "Open" from the Dialog Box... The associated application for the file type does open.. But the file doesn't open.. It gives an error. Why is that? Here's the Download Script I use (imsafm2_download.php): <?php session_start(); ?> <?php header("Content-Description: File Transfer"); header("Content-Type: application/force-download"); header("Content-Disposition: attachment; filename=".basename($F)); @readfile($F); ?> And here's the php code for the link which downloads the file: <a href=\"imsafm2_download.php?F=imsafm/$showfilesuser/$myrow[filename]\"><img src=b_newtbl.png border=0></a> Any help appreciated.
