php mySQL 房间预订日历显示预订时的错误日期

Question

我有一个 php MySql 预订日历，它显示房间是否按日期预订。问题是，它显示了错误的信息。例如，如果我预订了 5-6 号，则应该将第 5 号标记为红色，这意味着它是在 5 号预订的。显示为 6 号，但到 6 号 12:00:00 房间将空闲。再比如:我订的是23-25，显示的是24、25，但应该显示的是23-25，不知道问题出在哪里。

这是代码:

  function getAllRooms($date,$month,$year)
{
    global $db;
    $where = ' ';
    if ($_GET['room_type'] != '') {
        $where .= " HAVING room_type = '".$_GET['room_type']."'";
    }

    $sql = "SELECT room_type 
            FROM 
                room

                room_type 
            $where
            ";
    /*echo $sql;
    exit;*/
    $result = $db->Execute($sql);;
    $room = '';
    while (!$result->EOF) {
        $qs     = '?room_type='.$result->fields('room_type').'&month='.$month.'&year='.$year;
        $total  = get_total_rooms_by_type($result->fields('room_type'),$date,$month,$year);

抱歉，答案不多，但是..

好吧，我可以检查你的代码，但我相信你可以自己解决这个问题，因为 我相信这只是逻辑错误。 您可以做的是从头开始打印所有结果变量 通过它们进行调试。这样您就会知道哪一行出现问题。

然后您可以尝试自己解决该问题或在此处提出更精确的问题。

祝你好运! :)
