php mySQL房间预订日历显示预订日期错误

Question

我有一个php MySql预订日历，它显示了是否按日期预订房间。问题是，它显示了错误的信息。例如，如果我预订了5-6，它应该标记为第五个红色，这意味着它在5日被预订了。它显示6日但6点，12点00分房间将是免费的。另一个例子：如果我预订23-25，它显示24,25为预订，但它应该显示23-25，不知道问题在哪里。

下面是代码：

function getAllRooms($date,$month,$year)

    global $db;

    if ($_GET['room_type'] != '') {

    } 

    $sql = "SELECT room_type 
      FROM 
       room 
      GROUP BY 
       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); 
     $room .= 
     '<div class="'.$result->fields('room_type').'">

    }

    }

Answer 1

它实际上是时间不匹配的问题。在分贝我设置日期时间作为签入和结帐，但我检查sql与日期检索数据没有时间考虑。

现在还说：

$_newdate = $year.'-'.$month.'-'.$date . " " . "12:00:00"; 

工作就像一个魅力。 !!!!

Answer 2

对不起，没有太多的答案，但..

那么我可以通过你的代码，但我相信你可以自己解决这个问题，因为它的 我相信只是逻辑错误。 你可以做的是打印从开始的所有结果变量，并通过它们调试 。这样你就会知道哪条线给出了问题。

然后，您可以尝试自己解决它或在此处询问更精确的问题。

祝你好运！ :)
