How to create Dynamic Download Link with PHP?

Do not paste download link directly, insteaddo as following:

After receiving payment

Create a simple link that lead to downloadfile.php

in download file.php

check for cookie to validate a user

if cookie is found(user validated) then throw content of file as downloadable content using headers as following:

header('Content-Description: File Transfer');

header('Content-Type: application/octet-stream');

header('Content-Disposition: attachment; filename='.basename($file));

header('Content-Transfer-Encoding: binary');

header('Expires: 0');

header('Cache-Control: must-revalidate, post-check=0, pre-check=0');

header('Pragma: public');

header('Content-Length: ' . filesize($file));

flush();

readfile($file);

exit;

hope that helps:

store the path to the file in a database, along with a unique identifier and a timestamp of expiry. Then when a user accesses a link with the unique ID in the get variables, check the timestamp and fetch the file/display an error accordingly.

Really, this is not something that can be answered in the context of a Yahoo Answers Space. But your best bet is using a CMS (content managment system). I would take a look at something like drupal. Drupal has tons of tutorials on their website, and you might find a drupal module that does what you want. You are going to be looking at putting at least a couple weeks into getting familiar with servers, the terminology, and the CMS.
