<?php
    header("Content-type: text/html; charset=utf-8");
    session_start();

    // store count result in SESSION

    if (isset($_SESSION['count_days']) && !empty($_SESSION['count_days'])) {
        // if there is already quantity of days
        $count_days = $_SESSION['count_days'];
    } else {
        // or there are no days yet
        $count_days = 0;
    }
    // after data posted look if radio was checked
    if (isset($_POST['day'])) {
        $day = $_POST['day'];
    } else {
        $day = 0;
    }

    $count_days += $day;

    // save quanitity in SESSION
    $_SESSION['count_days'] = $count_days;

    if ($count_days == 8) {
        $checkbox_status = ' disabled';
    } else {
        $checkbox_status = '';
    }

//  echo $count_days;
