[PHP] downloading files
hi all, i've uploaded some files into my postgresql db, via a php script, and now id like to give a user the posibility to download these files via a php script. what would be the best way to do this bearing in mind that the files are 'integrated' into the db and are referenced by an oid. the table that contains the files has the original filename in one column and the oid of the file in another column besides other info on the table. any sugestion would be highly apreciated! thanx. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] downloading files
I did exactly what you said but its not working for me. I am getting the following error: Warning: filesize(): SAFE MODE Restriction in effect. The script whose uid is 20373 is not allowed to access /var/www owned by uid 0 in /home/virtual/site341/fst/var/www/html/test.php on line 3 I checked the rights and it its exactly what it should be...rwxr-xr-x...for all the directories leading to the download directory and all the files in the directory. Is this SAFEMODE error normal or is something turned on in that I need to turn off? Thanks, Aaron -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks, Aaron It seems that PHP can't read the file '/home/site/member/filename.xxx', what are the permissions for this file? PHP's rights are the same as the user Apache runs on. This is usually httpd or apache in most linux distributions. In your previous post, you were asking where to best place the file so it is protected somehow. You could actually place it in a simpler directory like /var/www/downloads then set x bit for the _other_ users of the downloads directory, so PHP can access files under it chmod o+x downloads and set all files under this directory to be readable by others (esp PHP) chmod o+r downloads/* THis way, PHP can't modify files in this directory. And no one can just download a file by entering a URL (since the files are outside the webserver path). goodluck!

Hi Aaron, [..] The download files are in a directory protected by htaccess which it is my understanding that PHP can go underneath htaccess to get access to the files. My problem is where do I put this directory? I was already told to put it outside the web root directory, [..] Both are good methods to protect your files. And yes, you can access your files because PHP is working on the servers side and doesnt need to obey the .htaccess restrictions you defined for user/clients. With .htaccess protection you can access them by yourself later using login/password combination. Outside your DocumentRoot you won't have the possibility and without any help of serverside processes you will not be able to access them. That way you also dont need to worry about any .htaccess settings :-) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The problem was solved. I added a call to the exit() construct at the end of
the function and haven't had any more problems since.

Hello.
I tried what you suggested and it's working alright. The problem is, that
it
doesn't always work. I adapted your suggestion to what I needed. Instead
of
creating a file, I made a fuction that does basically the same. All listed
files are links that enable the user to download them.
So far so good. I tested it on a couple files and it worked. But it seems
to
fail sometimes, showing what appears to be the contents of the HTTP-Header
and the file itself. If it's an audio file or something alike, it shows
all
sorts of weird characters, I assume them to be the actual binary contents
of
those files. If it's a text file, it shows the file, intact, but on the
page.
Again, I haven't been able to establish a pattern of behaviour on this. My
thesis is that the readfile function may have something to do with this,
as
it stores the contents of the file in the output buffer and maybe it's
showing them.
What troubles me is the fact that it doesn't have a certain behaviour,
instead, like I said, sometimes works, and sometimes it doesn't.

This will pop it up in a new window, leave the original window untouched, and they can choose save as from the file menu. if for some reason you DO want the original window to be refreshed, this could easily be done with a javascript onclick event in the above a tag. How can the file be stored in C:\sample.txt, for example? you have no control over where the user downloads the file to -- it's entirely up to them and/or their browser settings. actually, forcing a download really isn't true... in most cases your really forcing a 'save file as...' dialogue window.

[snip]
A couple of. Generally a browser will not leave the current page when
starting a file download - it simply remains on the page.
As for your question:
1) Generate a link to the exe file within your HTML output:
echo 'a href=sample.exeGet the sample.exe file/a';
2) If you don't have a file but need to construct it on the fly (or it is
not directly accessible from within your webserver), simply echo out the
data after sending an appropriate MIME headers.
Assuming you have the file contents in a variable called $export:
header('Content-Type: application/octet-stream');
header('Content-Length: ' . strlen($export));
header('Content-Disposition: attachment;filename=sample.exe');
echo $export;
exit();

[PHP] Downloading Files
I want to protect files from being downloaded and only allow people to download files which they have access too. I've done all the access control etc... but whats the best way for the user to download the file... Can you paste the file directly into the header? (get the file from the filesystem, mime encode it and put it in the header?) or copying the file to a web viewable temp dir to allow the user to download it? (dont really want to do this).

else

Adapt to your needs and don't even try this if you're not going to
validate the download directory and filename...

Re: [PHP] Downloading files
Try this: ?php // Open the file to send. $sFilePath = /home/scott/public_html/TEST.doc; $iFilePointer = fopen( $sFilePath, r ); // Get file content. $sContents = fread( $iFilePointer, filesize( $sFilePath ) ); // Close the file. fclose( $iFilePointer ); // Send HTTP headers. header( Expires: 0 ); header( Cache-Control: no-cache ); header( Content-Type: application/save-as ); header( Content-Disposition: attachment; filename=.basename( $sFilePath ).;); header( Content-Length: .filesize( $sFilePath ) ); // Feed file to client. echo $sContents; ? As you give the client Content-Type: application/save-as - it will not know what mime type the file is, and the browser will give the user a save-as prompt. This works in explorer - I haven't checked it in Mozilla etc - so you might have to tweak it a bit.

Re: [PHP] Downloading files
Using this method,.. works OK if you choose to save the file, however if you choose to open the file you get a weird behaviour where IE says it can't find the file and a subsequent prompt to create a new one. Does anyone know why it does this and how to overcome it ? At this stage I've resorted to using some simple javascript to prevent a user clicking on a file and advising them to use right-click save-as until I come up with a more reliable method.

Try removing the Expires Cache-Control headers. I doubt you'll be able to find a reliable way that works under all flavours of IE.

[PHP] Downloading files/docs
Hi all,
I've seen some posts and info elsewhere regarding downloading files - mostly
stating problems with the way IE handles this function.
What I'm trying to do is :
1 - offer files,.. .doc, .zip and others
2 - allow the user to click on a URL, or button
3 - have the options to Open or Save
4 - NOT have MS-Word come up within the browser window if user
chooses to Open
5 - IE save the file properly
Netscape seems to do all the rights things. But I want to get IE working,
(as best I can).
I'm using the following code-snippet within a PHP script,... browser type
gets checked earlier in the script,..
Currently, to avoid IE displaying .doc files within its window, I've
prevented the user from 'left-clicking' on the file's anchor with some
simple JS and forcing them to do a Save-As, which seems to work for IE, but
Netscape defaults to the URL for the name of the file :-(
Is there a better way to achieve all of the above ??
Is it possible to stop IE from opening the .doc within its browser window ??
Any advice would be greatly appreciated.
Thanks,
Jim.
// get the filename
$filename = $dataDIR . $fileid . .dat;
if ($browserType == IE) {
$attachment=;
} else {
$attachment=attachment;;
}
$attachment=;
$fn=urldecode($realname);
header('Content-Disposition:'.$attachment.' filename='.$fn.'');
header('Content-Type: application/octet-stream');
header('Content-Description: download file from site');
header('Content-Length: '.filesize($filename) );
header('Pragma: no-cache');
header('Expires: 0');
readfile($filename);
