[PHP] Redirect after download
I am writing a file download system and I need to be able to do a
redirect after the download is finished.
Basically, the user will be presented with a simple HTML page that
contains a link to download the file (href=/download.php?fileid=143).
I have the code to send the file working just fine, but I can not figure
out how to do a redirect after the download is complete. I have spent
the last hour searching the archives, and the closest I have found is:
http://marc.theaimsgroup.com/?l=php-generalm=106128750620349w=2
But I can't seem to find a way to actually do a Location style
redirect. Even static HTML does not display the way one would expect.
Using a small text file to download, I can view source from NS and see
the everything that was sent to the browser, and everything is there
(the ---Boundary(s), the text file, and the simple HTML line).
So my question is: How can I perform a redirect after the file has been
sent.
Thanks,
Justin
Here is a snippit of download.php (send_file() was found reading the
comments to the fread function in the PHP documention):
header(Content-Type: multipart/mixed; boundary=\-Boundary-12399\);
if(!send_file($file)) {
die(File transfer failed!);
exit;
}else{
print(\n);
print(---Boundary-12399\r\n);
print(Content-Type: text/html\r\n);
print(\r\n);
print htmlheadtitleSuccess/title/headbodybFile
transfer s
uccessful!/b/body/html;
print(\r\n---Boundary-12399\r\n);
print(\r\n);
exit;
}
function send_file($file) {
// read file and send to user
$status = FALSE;
if ( (!is_file($file['filelocation'])) or
(connection_status()!=0) ) return(FALSE);
print(---Boundary-12399\r\n);
print(Content-type: application/octet-stream\r\n);
print(Content-Disposition: inline; filename=\ .
$file['filename'] . \\r\n);
print(Content-length: . $file['filesize'] . \r\n);
print(Expires: . gmdate(D, d M Y H:i:s,
mktime(date(H)+2, date(i), date(s), date(m), date(d),
date(Y) ) ) . GMT\r\n);
print(Last-Modified: . gmdate(D, d M Y H:i:s). GMT\r\n);
//print(Cache-Control: no-cache, must-revalidate\r\n);
//print(Pragma: no-cache\r\n);
if ($fh = fopen($file['filelocation'], 'rb')) {
while(!feof($fh) and (connection_status()==0)) {
print(fread($fh, 1024*8));
flush();
}
$status = (connection_status()==0);
fclose($fh);
}
return($status);
}

Re: [PHP] How to load .php3 pages using PHP4
Comment that line again, and add .php3 to: AddType application/x-httpd-php .php .php3 This will tell apache to use PHP4 for both .php and .php3 files.

[PHP] reseting cookie_lifetime
I have:
session.cookie_lifetime = 1200
in my php.ini. I am using the PHP session functions that are working
fine, except I can't find out how to reset the lifetime timer. For
example, I log in, my script creates the session, and I do my work. After
20 minutes of working, the session expires and I have to re-login. How can
I reset the cookie_lifetime timer so that after each request the 20 minute
lifetime starts over?
Each script starts with:
session_name(mysessionname);
session_start();
And then checks session_is_registered('username')
