private messaging system....

[mykg4orce]

I needed some ideas as to how i could limit the user from sending a private message to anther user ONCE every 30 seconds. TO stop flooding...etc. I thought about using cookies, but a user could clear the cookie. And with sessions I do not know if it is possible to expire a session variable after a certain amount of time.

sure...set the session variable as the current time, then just check against it. If everything's ok, overwrite it, otherwise error out.

if(isset($_SESSION['last_time'])) {
   if($_SESSION['last_time'] >= (time()-30)) {
      die("You can only post once every thirty seconds");
   }
   else {
      $_SESSION['last_time'] = time();
   }
}
else {
   $_SESSION['last_time'] = time();
}
