Hi David,

if you have the GeoIP selector turned on, then it will always do a lookup. That's so that the $fromCountryId and $fromCountryName variables will be populated before it gets to the PHP section.

If you want to, you can bypass the standard lookup, and do it yourself if you want to. I think this will work:

$ip = modMetaModHelper::getUserIP();
$include_file = JPATH_SITE . DS . 'geoip' . DS . 'GeoIP.dat'; // adjust if necessary
if (!function_exists("geoip_open")) {
  include_once(JPATH_SITE . DS . "modules" . DS . "mod_metamod" . DS . "mod_metamod" . DS . "geoip-php4" . DS . 'geoip.inc');
}
// open the data file
$gi = geoip_open( $include_file, GEOIP_STANDARD );
$fromCountryId = utf8_encode(geoip_country_code_by_addr($gi, $ip));
geoip_close( $gi );

Naturally you'll need to do other stuff with that to insert it into a cookie, and to check for the cookie before you do the code above.

You mentioned nesting in another MetaMod. Yes, you could do that too, but I guess that you are wanting to cut down on the lookup for the sake of speed and efficiency, so I think that the code above will be best. Just down't forget to turn the GeoIP selector "off" so that it doesn't calculate it automatically first.

Hope that helps,
Stephen

$ip = modMetaModHelper::getUserIP();
$include_file = JPATH_SITE . DS . 'geoip' . DS . 'GeoLiteCity.dat'; // adjust if necessary
if (!function_exists("geoip_open")) {
  include_once(JPATH_SITE . DS . "modules" . DS . "mod_metamod" . DS . "mod_metamod" . DS . "geoip-php4" . DS . 'geoipcity.inc');
}
// open the data file
$gi = geoip_open( $include_file, GEOIP_STANDARD );
$geoip = geoip_record_by_addr($gi, $ip);
modMetaModHelper::convertToUtf8($geoip);
geoip_close( $gi );
// now you can use:
// $geoip->country_name
// $geoip->country_code
// $geoip->country_code3
// $geoip->region
// $geoip->city
// $geoip->postal_code
// $geoip->latitude
// $geoip->longitude
// $geoip->dma_code
// $geoip->area_code
