Use session variables so that the users can't resume downloading or can't even start downloading

How can we do that in php? anyway can get me started?

Thanks in advance.

Hi.

Try adding session_start(); at the top of the php download page, then before the page even shows, check for certain variables:

<?php
// Start the session
session_start();

// Check to see if they've logged in:
if(!isset($_SESSION['active'])){
    // Not logged in, Don't let them download
}
if($_SESSION['active'] == true && (!isset($_SESSION['download'])){
    // Don't have a download url, they get nothing
}
if(($_SESSION['active'] == true) && (isset($_SESSION['download'])) && (!isset($_SESSION['time_left'])){
    // No time to download!!
}
if(($_SESSION['active'] == true) && (isset($_SESSION['download'])) && ($_SESSION['time_left'] > 0){
    // They have time left in their session, let them download.
}

You would set these variables like so:

$_SESSION['var_name'] = "some data";

To use the time function, I don't know much about it, but I do know that you could make their session time-out. Perhaps what would be better is to do this:

if(($_SESSION['active'] == true) && (isset($_SESSION['download'])) && ($_SESSION['time'] > date(r)){

You would set $_SESSION['time'] to like 10, 15, 20 minutes or however long you want by manipulating the date function:

Hope I helped.
