I have a problem with posting variable to php script and getting result back without refreshing page. php script koord.php is tested and it's working fine.
This is my js code (adresa, mjesto and coords are text input boxes):
$(document).ready(function () {
    $('#coord_click').click(function () {
        provjera();
    });
});
function provjera() {
    var adresa = $('#adresa').val();
    var mjesto = $('#mjesto').val();
    var puna_adresa = adresa + " " + mjesto;
    $.post("koord.php", { puna_adresa: puna_adresa },function (result) {
        $('#coords').val(result);
    });
}
koord.php:
$puna_adresa = $_GET['puna_adresa']; 
function getCoordinates($address){ 
    $address = str_replace(" ", "+", $address); 
    $url = "maps.google.com/maps/api/geocode/…"; 
    $response = file_get_contents($url); 
    $json = json_decode($response,TRUE); 
    return ($json['results'][0]['geometry']['location']['lat'].",".$json['results'][0]['geometry']['location']['lng']); 
} 
echo getCoordinates($puna_adresa);
