Refreshing?

[cbrian]

I'm working on an online text based game where at one point you battle monsters. However, I've discovered that there's a loophole so that the user can refresh or press back to redo that part of the fight or exit. Is there any way to fix that? Thanks.

In my web applications, I always use a simple reloadPage function for doing reloads and redirects after processing form inputs and stuff. This way people cannot accidentally or intentionally resubmit with refresh or back.

function reloadPage () {
    // called without an arg, it will just reload the page with no GET/POST data
    if (func_num_args()) {
      $url = func_get_arg(0);
    } else {
      $url = $_SERVER["PHP_SELF"];
  }

Thanks, I'll try that!
