将多个会话变量从PHP插入到mySQL数据库中，为什么不能正常工作[关闭]

Question

Hi I cannot get the below query to work in order to insert the session data into the database, Could anyone please tell me what is wrong with it or what I can do to fix it? Thanks in advance.

<?php
session_start();
 if (isset($_POST['sub'])) {
$host='localhost';
$user='root';
$pass='';
$db='theatre_booking';

$con=mysqli_connect($host,$user,$pass,$db);

$row = $_POST['row'];
$_SESSION["row"]=$row;  

$zone = $_POST['zone'];
$_SESSION["zone"]=$zone;

$quantity = $_POST['numberOfTickets'];
$_SESSION["numberOfTickets"]=$quantity;



$sql="INSERT INTO booking(PerfDate, PerfTime, Name, Email, RowNumber) 
VALUES 
    '{$_SESSION['date']}',
    '{$_SESSION['time']}',
    '{$_SESSION['name']}',
    '{$_SESSION['email']}',
    '{$_SESSION['row']}')";

    if ($con->query($sql) === TRUE) {
    echo "Booking successful";
} else {
    echo "Error: " . $sql . "<br>" . $con->error;
}
 }





?>

Answer 1

you are missing opening bracket '(' after values in insert statement.

$sql="INSERT INTO booking(PerfDate, PerfTime, Name, Email, RowNumber) 
VALUES (
    '{$_SESSION['date']}',
    '{$_SESSION['time']}',
    '{$_SESSION['name']}',
    '{$_SESSION['email']}',
    '{$_SESSION['row']}')";

    if ($con->query($sql) === TRUE) {
    echo "Booking successful";
} else {
    echo "Error: " . $sql . "<br>" . $con->error;
}
