    Hello colleagues developers,
    I try to do a change of values with ajax but not work as I hope.
    When I debug the code, in PHP it work ok, but in the response in javascript is empty. I use de same code in a admin page and it work ok
    I've the following code:
    Code (Javascript):
    $(document).ready(function () {
        //chance cities
        $("#state").change(function() {
            $("#state option:selected").each(function() {
                state_id = $(this).val();
       + 'actions.json', {action: 'get-cities', state_id: state_id},
                function (response) {
                    $("#city").append(new Option('-- select --', 0));
                    response.forEach(element => {
                        $("#city").append(new Option(,;
    PHP (/front/action.php) ==
    case 'get-cities':
                if (iaView::REQUEST_JSON == $iaView->getRequestType()) {
                    $state = $_POST['state_id'];
                    $cities = [];
                    if (!empty($state)) {
                        $cities = $iaDb->assoc('id, city', 'state='.$state, 'city');
                        $iaView->assign('cities', $cities);
                        return $cities;
    Any idea.
