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列的格式为日期和时间类型。我应该如何在sql查询中发送变量？

编辑：添加了错误

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， CONSTRAINT Booking_ibfk_1 FOREIGN KEY（PerfDate，PerfTime）参考性能（PerfDate，PerfTime））'in 第58行/home/cuc/jk497/public_html/bookingReceipt.php

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']));

从this示例我将首先更改您拥有的代码：

$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：

查询具有特定的查询顺序

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

您将值作为数组发送，不确定原因，但您可以发送值

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

从头开始使用您的查询

变化：

$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)";

PHP试图向sql发送单独的日期和时间变量
