Question

I am going to write some web application which should detect user’s country and city. For example when user enters site web application should display information in his/her native language, it should say that his/her country (and city, I do not know whether it is possible or not). Do you know any database (IP database) or any other way to do this?

Answer 1

Try http://www.netimpact.com/faq

Its free for 250 queries in 24 hours.

Or you can use simple javascript code, that negotiates with client’s browser to detect exact latitude, and longitude.

// Check for geolocation support
if (navigator.geolocation) {
    // Use method getCurrentPosition to get coordinates
    navigator.geolocation.getCurrentPosition(function (position) {
        // Access them accordingly
        alert(position.coords.latitude + ", " + position.coords.longitude);
    });
}

However, This requires user’s permission to share his location.
