Hello! Thanks for your time in looking at this post.
I have a custom News section, with a custom Printer friendly articles. What I would like is to create some sort of pre check code, that will find out if the visitor is accessing the printer version article FROM the original article, or "referred" from the original article link, and if not, do something else.

I don't want people sending visitors to my printer version articles. Any ideas? Thanks!

Not sure how we missed this one selectric. Sorry about that. Take a look at this code in includes/nukesentinel.php as it should give you the ideas that you need:

Code:

function get_referer() {
  global $nuke_config;
  if(get_env("HTTP_REFERER")) {
    if(stristr(get_env("HTTP_REFERER"), $nuke_config['nukeurl'])) {
      return "on site";
    } elseif(stristr(get_env("HTTP_REFERER"), "http://localhost") || stristr(get_env("HTTP_REFERER"), "http://127.0.") || stristr(get_env("HTTP_REFERER"), "http://192.168.") || stristr(get_env("HTTP_REFERER"), "http://10.") || stristr(get_env("HTTP_REFERER"), "file://")) {
      return "local link";
    }
    return get_env("HTTP_REFERER");
  }
  return "none";
}
