Hi Alex,

personally I would make separate modules for each of these options, and put the JS/HTML in them. That keeps the code separate from presentation, and should make it easier to edit the JS/HTML without disturbing the "logic" side of it.

Then, download the GeoLiteCity database from MaxMind, unzip it, and put it into a folder called geoip in the root of your web directory.

Then create your MetaMod, and enable the GeoIP COuntry support in it. I assume you know how to set up your target modules etc. (i.e. unpublishing them or setting them to display on no menu items).

For the MetaMod PHP code I would do the following:

switch ($fromCountryId) {
  case 'US': return AAA;
  case 'CA': return BBB;
  case 'AU':
  case 'NZ': return CCC;
  case 'GB': return DDD;
  default: return EEE;
}


Replace the AAA-EEE above with the module ids that you want to use for each of the countries specified. EEE is the "fallback" (i.e. for all other countries). See how you can have several countries mapping to one module by stacking them on top of each other without a return statement, like the AU-NZ example above.

Best regards,
Stephen

If you want to detect cities then use GeoLiteCity.dat, otherwise use GeoIP.dat (i.e. just for countries) as it will be quicker and more lightweight for the server.

Then enable whichever one you installed, in any MetaMod that needs to use the information. By requiring it to be enabled this means that if it DOESN'T need it then it will same some processing time.

Cheers,
Stephen
