Php 无法从mysql表中检索数据

我正在将paypal支付信息插入“payments”表中。该表的结构如下：

CREATE TABLE `payments` (
 `payment_id` int(11) NOT NULL AUTO_INCREMENT,
 `txn_id` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
 `payment_gross` float(10,2) NOT NULL,
 `currency_code` varchar(5) COLLATE utf8_unicode_ci NOT NULL,
 `payment_status` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
 `payer_email` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 PRIMARY KEY (`payment_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

include 'config/database.php';
include 'DBController.php';
file_put_contents("log.txt", print_r($_POST, true));
//Get payment information from PayPal 
//$id = isset($_GET['id']) ? $_GET['id'] : '';
//$txn_id= isset($_GET['tx']) ? $_GET['tx'] : '';
//$payment_gross = isset($_GET['amt']) ? $_GET['amt'] : '';
//$currency_code = isset($_GET['cc']) ? $_GET['cc'] : '';
//$payment_status = isset($_GET['st']) ? $_GET['st'] : '';
//$txn_id = $_GET['tx'];
//$payment_gross = $_GET['amt'];
//$currency_code = $_GET['cc'];
//$payment_status = $_GET['st'];
$txn_id = $_POST['txn_id'];
$payment_gross = $_POST['mc_gross'];
$currency_code = $_POST['mc_currency'];
$payment_status = $_POST['payment_status'];
$payer_email = $_POST['payer_email'];
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$receiver_email = $_POST['receiver_email'];
file_put_contents("log1.txt", print_r($txn_id, true));
if(!empty($txn_id))
{
    $db = new DBController();
    //Check if payment data exists with the same TXN ID.
    $param_type="s";

    $param_value_array = array($txn_id);

    $paymentResult = $db->runQuery1("SELECT payment_id FROM payments1 WHERE txn_id = ?",$param_type,$param_value_array);

    if(!$paymentResult== 0)

付款已成功保存。我想从重定向到“success.php”页面时从paypal收到的txn_id上的同一个表中检索信息。我使用的代码如下所示：

CREATE TABLE `payments` (
 `payment_id` int(11) NOT NULL AUTO_INCREMENT,
 `txn_id` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
 `payment_gross` float(10,2) NOT NULL,
 `currency_code` varchar(5) COLLATE utf8_unicode_ci NOT NULL,
 `payment_status` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
 `payer_email` varchar(100) COLLATE utf8_unicode_ci NOT NULL,
 PRIMARY KEY (`payment_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

include 'config/database.php';
include 'DBController.php';
file_put_contents("log.txt", print_r($_POST, true));
//Get payment information from PayPal 
//$id = isset($_GET['id']) ? $_GET['id'] : '';
//$txn_id= isset($_GET['tx']) ? $_GET['tx'] : '';
//$payment_gross = isset($_GET['amt']) ? $_GET['amt'] : '';
//$currency_code = isset($_GET['cc']) ? $_GET['cc'] : '';
//$payment_status = isset($_GET['st']) ? $_GET['st'] : '';
//$txn_id = $_GET['tx'];
//$payment_gross = $_GET['amt'];
//$currency_code = $_GET['cc'];
//$payment_status = $_GET['st'];
$txn_id = $_POST['txn_id'];
$payment_gross = $_POST['mc_gross'];
$currency_code = $_POST['mc_currency'];
$payment_status = $_POST['payment_status'];
$payer_email = $_POST['payer_email'];
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$receiver_email = $_POST['receiver_email'];
file_put_contents("log1.txt", print_r($txn_id, true));
if(!empty($txn_id))
{
    $db = new DBController();
    //Check if payment data exists with the same TXN ID.
    $param_type="s";

    $param_value_array = array($txn_id);

    $paymentResult = $db->runQuery1("SELECT payment_id FROM payments1 WHERE txn_id = ?",$param_type,$param_value_array);

    if(!$paymentResult== 0)

返回0行。

请注意，货币很少是浮动的；这就是发明十进制的原因，但如果我只选择payment id only，那么我也无法检索任何内容。@如果id和status字段是255个长字符串，那么strawberrylook就好像数据库设计出了问题……您的表是payments1还是payments@james你能给plz硼酸吗
