How can I dynamically add username to IP address

I'm using utm_content[username] and utm_content[email] in the URLs that I email to people on my list.

This automagically gets assigned to sessions when people come in on those links.

However, the next time they return, let's say directly and not from my custom URL, clicky does not retain the same username that they were assigned before.

So I guess what happens is that the *session* is assigned that username, but I want the *visitor* assigned the username, or maybe the IP address.

Or maybe they get a cookie, and even if their IP changes, their username remains the same.

How can I do this?

Thanks! :)

I meant utm_custom, not utm_content.

Yes it's only for the session. If you want persistent then you should set cookies based on those values, then declare them with custom data on returning session.

PHP example, setting cookies:

if( isset( $_GET['utm_custom'] )) {
  foreach( $_GET['utm_custom'] as $key => $value ) {
    set_cookie( "utm_custom[{$key}]", $value, time()+(86400*365), '/');
  }
}

Reading cookies (this would go ABOVE your tracking code so these values are output and read by our tracking code and then sent to us)

if( $_COOKIE['utm_custom'] ) {
  echo "<script>var clicky_custom = { username: {}};";
  foreach( $_COOKIE['utm_custom'] as $key => $value ) {
    echo "clicky_custom.username.{$key} = '$value';";
  }
  echo "</script>";
}

I didn't test the code so there might be a bug but that should be mostly right.

Does the code work?
