On a site I'm working on we need to allow a user to download a file once only. The problem is, if the download fails they can try again. I only want it to be registered as a download if it completes successfully
The code I'm using at the moment;
set_time_limit(0);
ignore_user_abort(false);
//----------
//Code to validate the download token, make sure it hasn't been downloaded before etc.
//----------
//Send the headers
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$RemoteName.'"');
header('Content-length: '.filesize($LocalName));
//Send the file
ob_start();
$f = fopen($LocalName, 'r');
while(!feof($f)){
echo fread($f, 1024*1024*5);
ob_flush();
}
fclose($f);
//Update the database
mysql_query("UPDATE TABLE SET FIELD = 'DONE' WHERE ID = '$DLID'");This seems to be working fine (The mysql_query doesn't run if the user aborts/cancels/fails) but will there be any issues with browser compatibility or a better way to do it?
