Question

我必须在表单提交后使用dodirect付款方式。该表格将在网站上显示所有卡片详细信息，如卡片类型（签证或主人），卡片号，安全号码，有效期，卡上的姓名，地址，州，邮政，国家，电话，电子邮件等。

我搜索了如何使用dodirect方法，如下所示

<?php

/** DoDirectPayment NVP example; last modified 08MAY23.
 *
 *  Process a credit card payment. 
*/

$environment = 'sandbox';   // or 'beta-sandbox' or 'live'

/**
 * Send HTTP POST Request
 *
 * @param   string  The API method name
 * @param   string  The POST Message fields in &name=value pair format
 * @return  array   Parsed HTTP Response body
 */
function PPHttpPost($methodName_, $nvpStr_) {
    global $environment;

    // Set up your API credentials, PayPal end point, and API version.
    $API_UserName = urlencode('my_api_username');
    $API_Password = urlencode('my_api_password');
    $API_Signature = urlencode('my_api_signature');
    $API_Endpoint = "https://api-3t.paypal.com/nvp";
    if("sandbox" === $environment || "beta-sandbox" === $environment) {
        $API_Endpoint = "https://api-3t.$environment.paypal.com/nvp";
    }
    $version = urlencode('51.0');

    // Set the curl parameters.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $API_Endpoint);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);

    // Turn off the server and peer verification (TrustManager Concept).
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);

    // Set the API operation, version, and API signature in the request.
    $nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$API_Password&USER=$API_UserName&SIGNATURE=$API_Signature$nvpStr_";

    // Set the request as a POST FIELD for curl.
    curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);

    // Get response from the server.
    $httpResponse = curl_exec($ch);

    if(!$httpResponse) {
        exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');
    }

    // Extract the response details.
    $httpResponseAr = explode("&", $httpResponse);

    $httpParsedResponseAr = array();
    foreach ($httpResponseAr as $i => $value) {
        $tmpAr = explode("=", $value);
        if(sizeof($tmpAr) > 1) {
            $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
        }
    }

    if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {
        exit("Invalid HTTP Response for POST request($nvpreq) to $API_Endpoint.");
    }

    return $httpParsedResponseAr;
}

// Set request-specific fields.
$paymentType = urlencode('Authorization');              // or 'Sale'
$firstName = urlencode('customer_first_name');
$lastName = urlencode('customer_last_name');
$creditCardType = urlencode('customer_credit_card_type');
$creditCardNumber = urlencode('customer_credit_card_number');
$expDateMonth = 'cc_expiration_month';
// Month must be padded with leading zero
$padDateMonth = urlencode(str_pad($expDateMonth, 2, '0', STR_PAD_LEFT));

$expDateYear = urlencode('cc_expiration_year');

// Add request-specific fields to the request string.
$nvpStr =   "&PAYMENTACTION=$paymentType&AMT=$amount&CREDITCARDTYPE=$creditCardType&ACCT=$creditCardNumber".
            "&EXPDATE=$padDateMonth$expDateYear&CVV2=$cvv2Number&FIRSTNAME=$firstName&LASTNAME=$lastName".
            "&STREET=$address1&CITY=$city&STATE=$state&ZIP=$zip&COUNTRYCODE=$country&CURRENCYCODE=$currencyID";

// Execute the API operation; see the PPHttpPost function above.
$httpParsedResponseAr = PPHttpPost('DoDirectPayment', $nvpStr);

if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) {
    exit('Direct Payment Completed Successfully: '.print_r($httpParsedResponseAr, true));

    exit('DoDirectPayment failed: ' . print_r($httpParsedResponseAr, true));

我不知道如何在提交我网站上的表单时使用此代码。提交表格后，任何人都可以帮我解决如何使用此问题。

提前致谢：）

Answer 1

这真的不是一个很好的功能。它基本上是希望你只是填写函数中的值而不是传递它们。这是一个非常粗略的例子，你可以看到它是根据评论在2008年最后一次更新。

但是，如果你想使用它，你只需填写所有那些显示“my_api_username”之类的占位符，并附上你想要实际包含的数据。

如果你想要更容易使用的东西，我建议使用我开发并保持多年的PHP library for PayPal。它是最新的，包含运行DoDirectPayment的直接样本。你可以在几分钟内完成它。

如果您对此感兴趣，我也会通过屏幕分享提供30分钟的免费培训。

实际上有可用于DoDirectPayment的样本作为https://www.x.com/developers/paypal/documentation-tools/paypal-sdk-index#expresscheckoutnew

上提供的官方SDK的一部分

建议使用官方SDK并检查其中的示例。如有任何问题，请在此处发回或在https://github.com/paypal/merchant-sdk-php/issues
