Temporary Link Script

[joshedgar]

Hi guys,

 

Does anyone know how to make a PHP script to generate temporary download links that expire after 10 minutes?

And the temp link is generated at a PHP page which after 10 seconds redirects to their requested download?

I can use PHP and Htaccess for this.

 

This is what I want:

 

The user wants to download a file. So the link goes to say:

http://www.my-website.com/download.php?file=video.mp4

 

Then at that script, I want it to wait 10 seconds while they are looking at an advertisement, and then during that ten seconds, it should generate a random MD5 code, such as:

782d1a1a7a0a34c39995e1fa95efdbf5

 

It then passes this to a temporary download link on my server:

http://www.my-website.com/download/782d1a1a7a0a34c39995e1fa95efdbf5/videos/video.mp4

 

Which is a cover-up for the REAL file URL, which is:

http://www.my-website.com/files/videos/video.mp4

 

However, after about 10 minutes that temporary link expires and they have to go back to download.php for it to generate them a new code, if they want to download the file again.

E.g. I want to protect my files against leeching with using my own script, without using Lix.in or a Frame or anything.

 

Is there a way to do this?

 

Thanks!

Anybody know?

have a MySQL database that have 3 fields

file, hash, timestamp

 

if the timestamp is greater than the time+(10*60*60) then delete the records

 

now on a php page have the link something like ?file=782d1a1a7a0a34c39995e1fa95efdbf5

 

Now the 782d1a1a7a0a34c39995e1fa95efdbf5 is NOT the filename hash its something like md5(time().$filename) this is stored in the database under hash and the file name in the file field..

 

now when someone clicks the link ?file=782d1a1a7a0a34c39995e1fa95efdbf5

look up in the database to find hash=$_GET['file'], and pull the filename

 

now use readfile to pull that data, search form for forced downloads

 

i hope that makes sense

I think I understand, but, I'd rather just keep it simple like having my links on the page be "download.php?file=videos/video.mp4".

My latest attempt was doing md5(rand,1) or something like that, I read it in a book. Then I was going to do some stuff in .htaccess to make that work but I realized that wouldn't terminate the links properly.

 

Basically what I want to do is something like this:

http://tanksoftware.com/tutes/leechprotection.html

 

But I don't understand all that, or how I'm going to start the functions properly with the current $_GET variables i have.

Thank you

[MadTechie]

yes and the script above will do that!!

 

download.php?file=videos/video.mp4

$_GET['file'] and create the mySQL entry..etc

 

display averts then redirect to download.php?hash=$hash

and have $_GET['hash'] for the downloads

[joshedgar]

Well I'm not too good with MySQL beyond just basic form inputs.

Can you please give me some code itself to help me understand how to put this all together?

I can make the mysql DB/table.

what php code do you have so far ?

[joshedgar]

Just to clarify, the above code currently takes

http://www.pspstop.net/vip.php?path=music&filename=greenday.rar

And turns it into

http://www.pspstop-vip.info/vip_files/music/greenday.rar

 

I just want to have temporary links so they dont actually see that direct link, but a randomly generated temporary one.
