Smart ip patch for views location proximity fitler

I create a small patch for location module based on this http://drupal.org/node/820116 for use the proximity filter with the data retrive by this module.

In location.views.inc after:

case 'uid_arg':
      if ($userhandler = $view->display_handler->get_handler('argument', $options['uid_arg'])) {
        $uid = $userhandler->get_value();
        if ($uid && is_numeric($uid) && $tempuser = user_load(array('uid' => $uid))) {
          $coordinates['latitude'] = (float) $tempuser->location['latitude'];
          $coordinates['longitude'] = (float) $tempuser->location['longitude'];
        }
      }
      break;

add

case 'smartip':
      if (module_exists('smart_ip')) {
        if ($_SESSION['smart_ip']['location']['longitude']!=0) { // intentional assignment of $geoip
          $coordinates['latitude'] = $_SESSION['smart_ip']['location']['latitude'];
          $coordinates['longitude'] = $_SESSION['smart_ip']['location']['longitude'];
        }
      }
      else if ($options['latitude'] && $options['longitude']) {
        $coordinates['latitude'] = (float) $options['latitude'];
        $coordinates['longitude'] = (float) $options['longitude'];
      }
      break;

and in handlers/location_views_handler_filter_proximity.inc after

 if (module_exists('gmap')) {
       $form['origin']['#options']['latlon_gmap'] = t('Latitude / Longitude input (use map)');
     }

add

if (module_exists('smart_ip')) {
      $form['origin']['#options']['smartip'] = t("Position of the visitor (0,0 if unset)");
    }

Now in the filter set "Position of the visitor (0,0 if unset)" to works.
Also i found this tutorial for who doesn't want to change location module: http://envisioninteractive.com/drupal/user-targeted-content-with-drupal-...
