我对这段代码感到很头疼，我知道我错过了一些简单的东西。我正在尝试将用户数据输入到名为 tbl_order 的表中

这是我的代码:

    <?php
    session_start();
    $connection = mysqli_connect('localhost', 'root', '', 'bookstore');

if (isset($_POST['submitted'])){

    $cTotal = $_SESSION['checkoutCartTotal'];
    $cName = $_POST['cardName'];
    $cNumber = $_POST['cardNum'];
    $cAdress = $_POST['cusAddress'];
    $cCity = $_POST['cusCity'];
    $cEmail = $_POST['cusEmail'];
    $cPhone = $_POST['cusPhone'];
    $sqlinsert = "INSERT INTO tbl_order (total_price, credit_card_number, fname, email, address, phone, city) VALUES ('$cTotal', $cNumber', '$cName', '$cEmail', '$cAdress', '$cPhone', '$cCity')";
    if (!mysqli_query($connection, $sqlinsert)) {
        die('Error inserting new record');
    } 


    $newrecord = "Thank you for making your purchase!";

}



?>

我得到的错误是我指定的错误插入数据库，我不知道我在哪里犯了错误

这是我的 tbl_order 数据库:

   CREATE TABLE `tbl_order` (
  `order_id` int(100) NOT NULL,
  `cus_id` int(100) NOT NULL,
  `prod_no` int(11) NOT NULL,
  `total_price` text NOT NULL,
  `credit_card_number` text NOT NULL,
  `fname` text NOT NULL,
  `email` text NOT NULL,
  `address` text NOT NULL,
  `phone` text NOT NULL,
  `city` text NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

INSERT INTO `tbl_order` (`order_id`, `cus_id`, `prod_no`, `total_price`, `credit_card_number`, `fname`, `email`, `address`, `phone`, `city`) VALUES
(1, 1, 1, '350', '2147483647', '', '', '', '0', '');


ALTER TABLE `tbl_order`
  ADD PRIMARY KEY (`order_id`),
  ADD KEY `cus_id` (`cus_id`),
  ADD KEY `prod_no` (`prod_no`);

ALTER TABLE `tbl_order`
  MODIFY `order_id` int(100) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=2;

ALTER TABLE `tbl_order`
  ADD CONSTRAINT `tbl_order_ibfk_1` FOREIGN KEY (`cus_id`) REFERENCES `customer` (`cus_id`),
  ADD CONSTRAINT `tbl_order_ibfk_2` FOREIGN KEY (`prod_no`) REFERENCES `tblproduct` (`prod_no`);

有人可以帮助我吗，我将不胜感激!

最佳答案

您在查询中错过了 $cNumber 之前的单引号

"INSERT INTO tbl_order (total_price, credit_card_number, fname, email, address, phone, city) 
    VALUES ('$cTotal', '$cNumber', '$cName', '$cEmail', '$cAdress', '$cPhone', '$cCity')"
