How to block registration by country in PHP with https?

  • 772

Is there any way to know through PHP the origin of the visit?

I would like to hide the registration button and show a message if the visitor is not from Spain, since the application would not work.

Something like:

if($pais != "ES"){
      echo "<p>No ofrecemos servicio para tu pais.</p>";
else{
      echo "<button type='submit'>Enviar</button>";
}
php

  1. What you can do is check, through the IP, the country of the visitor.

    You can use the hostip.info API.

    Example code:

    <?php
// Cogemos la IP del usuario del array que nos pasa el servidor
$user_ip = $_SERVER['REMOTE_ADDR'];

// Iniciamos el handler de CURL y le pasamos la URL de la API externa
$ch = curl_init("http://api.hostip.info/country.php?ip=$user_ip");

// Con este comando le pedimos a CURL que, en vez de mostrar
// el resultado en pantalla, nos lo devuelva como una variable
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Y simplemente hacemos la petición HTTP.
$country_code = curl_exec($ch);

// Y para muestra, un botón, vamos a probar que funciona bien:
echo "Este adorable servidor ha detectado que tu código de país es... $country_code";
?>

    Hope this can help you.

    All the best.

    I found one that worked for me:

    $country = "";
$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://ipinfo.io/{$ip}"));
$country = $details->country;

  3. In the previous answers, either the website does not work or the service is not very precise. In my case, it places me in Alcobendas, Madrid and that is not the case.

    I quite like this other one https://www.geoplugin.net

    Making the following call you will be able to obtain the information of an IP in json format: echo file_get_contents('http://www.geoplugin.net/json.gp?ip=IP_ADDRESS');

    You have more information in this article: https://academy.leewayweb.com/como-restrictir-el-acceso-a-una-web-segun-el-pais-del-visitante/

    According to Pablo Gutierrez 's comment , I edit and update:

    //Obtener IP del visitante
function get_client_ip_server() 
{
    $ipaddress = '';
    if ($_SERVER['HTTP_CLIENT_IP'])
        $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
    else if($_SERVER['HTTP_X_FORWARDED_FOR'])
        $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
    else if($_SERVER['HTTP_X_FORWARDED'])
        $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
    else if($_SERVER['HTTP_FORWARDED_FOR'])
        $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
    else if($_SERVER['HTTP_FORWARDED'])
        $ipaddress = $_SERVER['HTTP_FORWARDED'];
    else if($_SERVER['REMOTE_ADDR'])
        $ipaddress = $_SERVER['REMOTE_ADDR'];
    else
        $ipaddress = 'UNKNOWN';
 
    return $ipaddress;
}

$ipVisitante = get_client_ip_server();

if ($ipVisitante!='UNKNOWN')
{
    $data = json_decode( file_get_contents('http://www.geoplugin.net/json.gp?ip='.$ipVisitante, true ));

    $bannedCountries = array('AR', 'UY' );

    if ( in_array( $data->geoplugin_countryCode, $bannedCountries  )  ) 
    {
        echo 'No se admite gente de '.$data->geoplugin_countryName;
    } 
    else 
    {
        echo 'Los visitantes de '.$data->geoplugin_countryName.' siempre son bienvenidos :)';
    }
}
else
{
    echo "IP desconocida";
}
