Country Restriction Script

[lambdacerro]

Ok, releasing the code and database:

What you need:
A website (duh)
A IP To Country Database (included here)

So the script is like this:

PHP Code:

<?php
// Check if the cookie exists
if( empty($_COOKIE['IsValid']) ) {

    $valid = 'true';

    // Establishing a database connection
    $dbh=mysql_connect("localhost:3306","USER","PASS");
    mysql_select_db("IP_ToCountry_Database");

    // Getting User's IP
    $ip = $_SERVER["REMOTE_ADDR"];

    // Executing main query
    $country_exec = mysql_query("SELECT * FROM iptocountry WHERE ipto >= inet_aton('$ip') AND ipfrom <= inet_aton('$ip')");

    // Fetching the record
    $ccode_fetch=mysql_fetch_assoc($country_exec);

    // Getting the country code from the array
    $pais=$ccode_fetch['country2'];

    // Declaring the Allowed Countries by their CountryCode2
    $allowed = array('US', 'AR', 'UY', 'BR', 'FR');

    // Verifying if the user belongs to any of the allowed countries
    if (!in_array($pais, $allowed)) {
    $valid = 'false';
    }
    // Setting the cookie for a 10 minutes life
    setcookie("IsValid", $valid, time()+600);
    mysql_close($dbh);
    if ( $_COOKIE['IsValid'] == 'false' ) {
    echo "Not allowed country";
    die();
    }
}else{
    if ( $_COOKIE['IsValid'] == 'false' ) {
    echo "Not allowed country";
    die();
    }
}
?>

There you have to set the MySQL Connection and the valid countries array.
You can get the countrycode2 of all the countries from here:
http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

You can get the IP To Country Table for free at http://ip-to-country.webhosting.info/
But it's in csv, I passed it to sql and attached.

I added this script at init.php, but I don't think init.php is the best place for adding that code.

That's All.

NOW I want to know how to transform this script in a vBulletin plugin, I think the ip to country table can be added to vBulletin database, and in the script use the db=> thing.

Thank you
