how to change domain name according to country wise in wordpress

Question

I have my WordPress site hosted on nginx server. Now, I have created a sub-domain name say us.example.com How can I change the WordPress URL according to country wise when the site is open in united states i.e us.example.com?

Answer 1

There is a website that provides geolocation of a given ip (actually there are many, but I will just focus on this one): http://ip-api.com/

You can use the information they provide in order to redirect your visitors to the appropriate sub-domain like this:

$this_ip = $_SERVER["REMOTE_ADDR"];
$get_ip_info = file_get_contents("http://ip-api.com/json/".$this_ip);
$ip_info = json_decode($get_ip_info);
$countryCode = strtolower($ip_info->{"countryCode"});

header("Location: http://".$countryCode.".example.com");    

Of course, there are numerous countries and since is not practically possible to maintain a subdomain for each one, you can use the "if" statement to narrow down the redirect options:

if($countryCode=="fr"){ //french
    header("Location: http://fr.example.com");
}else
if($countryCode=="de"){ //german
    header("Location: http://de.example.com");
}else
if($countryCode=="gr"){ //greek
    header("Location: http://gr.example.com");
}else{ //universal
    header("Location: http://www.example.com");
}

Hope this helps you!
