PHP试图将单独的日期和时间变量发送到sql

Question

我正在尝试将两个单独的变量发送到 mysql 数据库，一个用于日期，一个用于时间。目前，这两个变量都是字符串，mysql 的列被格式化为日期和时间类型。我应该在我的 sql 查询中发送什么变量？

编辑：添加错误

致命错误：带有消息的未捕获异常“PDOException” 'SQLSTATE [23000]：完整性约束违规：1452 无法添加或 更新子行：外键约束失败（jk497.Booking, 约束 Booking_ibfk_1 FOREIGN KEY (PerfDate, PerfTime) 参考 性能（PerfDate，PerfTime））' /home/cuc/jk497/public_html/bookingReceipt.php 在第 58 行

我的代码

$time = "17:00:00"; 
$sql = "insert into Booking values (':id', ':date', ':time', ':fullName', ':email', ':rowNum', ':numSeats', ':bookedSeats');"; 
$handle = $conn->prepare($sql); 
$handle->execute(array(':id' => $_SESSION['id'], ':date' => $SESSION['date'], ':time' => $time, ':fullName' => $_SESSION['fullName'], ':email' => $_SESSION['email'], ':rowNum' => $seatIndex, ':numSeats' => $_SESSION['numSeats'], ':bookedSeats' => $_SESSION['bookedSeats']));

Answer 1

从this 示例我首先将代码更改为：

$sql = "insert into Booking ('id','date','time','fullName','email','rowNum','numSeats','bookedSeats') values (:id,:date,:time,:fullName,:email,:rowNum,:numSeats,:bookedSeats)"; 
$handle = $conn->prepare($sql); 
$handle->bindParam(':id',$_SESSION['id']);
$handle->bindParam(':date',$SESSION['date']);
$handle->bindParam(':time',$time);
$handle->bindParam(':fullName',$_SESSION['fullName']);
$handle->bindParam(':email',$_SESSION['email']);
$handle->bindParam(':rowNum',$seatIndex);
$handle->bindParam(':numSeats',$_SESSION['numSeats']);
$handle->bindParam(':bookedSeats',$_SESSION['bookedSeats']);

$handle->execute();

需要考虑的事项：

1. 查询有特定的查询顺序

   insert into table () values ();
   insert into table values (); //is what you had (this is not correct and will never work afaik)
   

2. 您将值作为数组发送，不知道为什么，但您可以发送值

   bind_param($_SESSION['id'],$SESSION['date'],$time,$_SESSION['fullName'],$_SESSION['email'],$seatIndex,$_SESSION['numSeats'],$_SESSION['bookedSeats'])
   

从头开始处理您的查询

改变：

$sql = "insert into Booking values (':id', ':date', ':time', ':fullName', ':email', ':rowNum', ':numSeats', ':bookedSeats');"; 

进入

$sql = "insert into Booking (id,date,time,fullName,email,rowNum,numSeats, bookedSeats) values (:id,:date,:time,:fullName,:email,:rowNum,:numSeats, :bookedSeats)";
