now to the main module file, in our case we are using a free geoip api from http://freegeoip.net/ but you could replace it with any other geoip api.
we are also not going strict to continents so we added our own routing, here are the subsites we use:
- North America
- Europe
- Oceania / Australia
- South America / Brazil
- Hong Kong
- China / Rest of Asia
so here is the module code:
<?php
function geoip2continent_init(){
// get current domain
$domain = domain_get_domain();
$current_domain_id = $domain['domain_id'];
// check if is front page and if current domain is the main domain
if ((drupal_is_front_page() == TRUE) && ($current_domain_id == 1)){
$continent = getContinentCodeFromIP();
switch($continent){
case "NA": // user from North America
$forward_to_domain = "2";
break;
case "EU": // user from Europe
$forward_to_domain = "3";
break;
case "OC": // user from Oceania / Australia
$forward_to_domain = "4";
break;
case "SA": // user from South America / Brazil
$forward_to_domain = "5";
break;
case "HK": // user from Hong Kong
$forward_to_domain = "6";
break;
case "AS": // user from China / Asia
$forward_to_domain = "7";
break;
}
// redirect
domain_goto(domain_lookup($forward_to_domain));
} else {
// if not front page don't redirect
}
}
function getContinentCodeFromIP(){
$results = file_get_contents("http://freegeoip.net/csv/".$_SERVER['REMOTE_ADDR']);
$results = explode(",",$results);
$country = $results[1];
$country_code = str_replace('"','',$country);
if($country_code == "HK"){
return $country_code;
}
$result = db_query('SELECT g.country, g.continent FROM {geoip2continent} g WHERE g.country = :country',
array(':country' => $country_code))->fetchAll();
return $result[0]->continent;
}
As you see were are also redirecting only in case, that person comes to the home page.
