Question

我已经开发了一个PHP和PHP的Web应用程序。 MySQL的。我得到了房间分配模块的一部分问题。

在房间分配模块中，用户可以根据需要选择多个复选框（时间段）。在后端，我收集这些时间并保存到数据库中。

有时，相同的数据会两次插入数据库。它只发生过一段时间。大多数情况下我得到了适当的输出。

我的问题是：

为什么它只在某些时候发生？
创建重复值的位置
怎么回事？
如何纠正这个问题!!

请有人帮我避免这个问题。!!!

我的插入编码：

    $admin = $_POST['admin'];

    $roomno = $_POST['str_roomno']; //unique No
    $currentdate = $_POST['str_currentDate'];
    $employeeID = $_POST['str_empID']; //current user ID

    $list_id = $_POST['list'];     //collect list of time slot from previous page
    $total_checkedRows   = count($list_id);   //counting the total slot from previous page



    for($i = 0; $i < $total_checkedRows; $i++)
        {
            $fromTime =  $_POST['time_fromTime'.$list_id[$i]];
            $endTime =  $_POST['time_endTime'.$list_id[$i]];
            $status  = $_POST['str_status'.$list_id[$i]];
            $reason =  $_POST['str_comment'] ; 
            $statusCheck = "occupied";

            if(isset($_POST['id_bookedID'.$list_id[$i]])){
                $id_lineID = $_POST['id_bookedID'.$list_id[$i]];
            }

            if($status == 1)
            {
            $insertSQL = sprintf("INSERT INTO hrms_room_calendar (room_id, booking_date, from_time, to_time, employee_id , booking_status, reason) VALUES (%s, %s, %s, %s, %s, %s, %s)",
                                   GetSQLValueString($roomno, "int"),
                                   GetSQLValueString($currentdate, "date"),
                                   GetSQLValueString($fromTime, "text"),
                                   GetSQLValueString($endTime, "text"),

                                   GetSQLValueString($statusCheck, "text"),
                                   GetSQLValueString($reason, "text"));

              $Result1 = mysql_query($insertSQL) or die(mysql_error());
            } 
            else if ($status == 2)
            {
                $updateQuery = sprintf("update hrms_room_calendar set booking_status = %s , employee_id = %s, reason = %s where booking_id = %s",
                                   GetSQLValueString($statusCheck, "text"),
                                   GetSQLValueString($employeeID, "int"),
                                   GetSQLValueString($reason , "text"),
                                   GetSQLValueString($id_lineID, "int"));
                $Result1 = mysql_query($updateQuery) or die(mysql_error());
            }

在我不知情的情况下插入了重复值
