PDO bindParam 不工作“在非对象上的 bindParam()”

Question

我正在为我正在创建的 CMS 试用 Mollie 支付处理器，但遇到了问题。当我尝试将数据输入 MySQL 数据库时，它不会这样做。我收到此错误：

致命错误：在第 83 行的 /home/ubuntu/workspace/examples/01-new-payment.php 中的非对象上调用成员函数 bindParam()

这是完整的代码：

<?php
/*
 * Example 1 - How to prepare a new payment with the Mollie API.
 */

$amount      = 100.50;
$description = "Booking for Villa Hijau";
$days        = 10;
$name        = "####";
$email       = "####";

try {
    /*
     * Initialize the Mollie API library with your API key.
     *
     * See: https://www.mollie.com/beheer/account/profielen/
     */
    include "initialize.php";

    /*
     * Generate a unique order id for this example. It is important to include this unique attribute
     * in the redirectUrl (below) so a proper return page can be shown to the customer.
     */
    $order_id = time();

    /*
     * Determine the url parts to these example files.
     */
    $protocol = isset($_SERVER['HTTPS']) && strcasecmp('off', $_SERVER['HTTPS']) !== 0 ? "https" : "http";
    $hostname = $_SERVER['HTTP_HOST'];
    $path     = dirname(isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : $_SERVER['PHP_SELF']);

    /*
     * Payment parameters:
     *   amount        Amount in EUROs. This example creates a € 10,- payment.
     *   description   Description of the payment.
     *   redirectUrl   Redirect location. The customer will be redirected there after the payment.
     *   webhookUrl    Webhook location, used to report when the payment changes state.
     *   metadata      Custom metadata that is stored with the payment.
     */
    $payment = $mollie->payments->create(array(
        "amount" => $amount,
        "description" => $description,
        "redirectUrl" => "{$protocol}://{$hostname}{$path}/03-return-page.php?order_id={$order_id}",
        "webhookUrl" => "{$protocol}://{$hostname}{$path}/02-webhook-verification.php",
        "metadata" => array(
            "order_id" => $order_id
        )
    ));

    /*
     * In this example we store the order with its payment status in a database.
     */
    database_write($order_id, $payment->status, $amount, $description, $days, $name, $email);

    /*
     * Send the customer off to complete the payment.
     */
    header("Location: " . $payment->getPaymentUrl());
}
catch (Mollie_API_Exception $e) {
    echo "API call failed: " . htmlspecialchars($e->getMessage());
}


/*
 * NOTE: This example uses a text file as a database. Please use a real database like MySQL in production code.
 */
function database_write($order_id, $status, $amount, $description, $days, $name, $email)
{
    $db_user  = 'mollie';
    $db_pass  = '####';
    $order_id = intval($order_id);
    // Use $status to get the order status
    $dbh      = new PDO('mysql:host=localhost;dbname=orders', $db_user, $db_pass);
    $stmt     = "INSERT INTO order (id, order_name, order_description, order_amount, order_customer, order_customer_email, order_status) VALUES (?,?,?,?,?,?,?)";
    if($stmt){
    $stmt->bindParam($order_id,$name,$description,$amount,$name,$email,$status);
    $stmt->execute();
    }
}

Answer 1

你应该准备好你的sql语句

 $stmt = $dbh->prepare( "INSERT INTO order 
  (id, order_name, order_description, order_amount, order_customer, 
 order_customer_email, order_status) 
           VALUES (?,?,?,?,?,?,?)";

就像建议的 bu Fred-ii 一样小心，因为你使用的是“订单”这个词，

这是 MySQL 的保留字，

那么你应该在这个词周围使用反引号

 `order`  

Answer 2

你在一个字符串上调用bindParam()。

你必须先使用PDO::prepare。请参阅文档here
