Question

目前，我在线上有一个在线现场应用程序，因此这对于处理付款至关重要。

许多试图完成付款的人都与我联系，有的人说他们的URL不完全合格，有的人说也没有进入PayPal页面并且无法正确加载。

我认为已经通过添加if不存在子句（以前在SDK GitHub上找到）来解决了合格的URL问题。

由于我是使用PayPal Rest API的新手，因此我不确定对其中可能存在的问题有任何其他结论

我从start.php开始，这很好并且保留了我的PayPal凭据。没问题。

此过程中的下一个是checkout.php

use PayPal\Api\Payer;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\Details;
use PayPal\Api\Amount;
use PayPal\Api\Transaction;
use PayPal\Api\RedirectUrls;
use PayPal\Api\Payment;

include '../src/func/manage.php';
include '../src/func/pay.php';
include '../src/func/getQnA.php';
require 'start.php';

// Getting information for user
$draw = filter_input(INPUT_POST, "drawID", FILTER_DEFAULT);
$quantity = filter_input(INPUT_POST, "quantity", FILTER_DEFAULT);
$phone = filter_input(INPUT_POST, "phone", FILTER_DEFAULT);
$fname = filter_input(INPUT_POST, "fname", FILTER_DEFAULT);
$lname = filter_input(INPUT_POST, "lname", FILTER_DEFAULT);
$email = filter_input(INPUT_POST, "email", FILTER_DEFAULT);
$selectedAns = filter_input(INPUT_POST, "ansID", FILTER_DEFAULT);
$questionID = filter_input(INPUT_POST, "questionID", FILTER_DEFAULT);
$product = getTitle($draw);
$price = getPrice($draw);
$total = $quantity*$price;
$ticketsLeft = ticketsLeft($draw);
$corrAns = checkQuestion($questionID, $selectedAns);

if($corrAns == "false"){
    header("Location: /payment/pay.php?success=false&wrong=true");
    die();
}

if($ticketsLeft <= 0){
    header("Location: /payment/pay.php?success=false&sold=true");
    die();
}

$payer = new Payer();
$payer->setPaymentMethod('paypal');

$item = new Item();
$item->setName($product)
    ->setCurrency('GBP')
    ->setQuantity($quantity)
    ->setPrice($price);

$itemList = new ItemList();
$itemList->setItems([$item]);

$details = new Details();
$details->setShipping(0.00)
    ->setSubtotal($price*$quantity);

$amount = new Amount();
$amount->setCurrency('GBP')
    ->setTotal($total)
    ->setDetails($details);

$transaction = new Transaction();
$transaction->setAmount($amount)
    ->setItemList($itemList)    
    ->setDescription(SITE_NAME)
    ->setInvoiceNumber(uniqid());

$successUrl = SITE_URL . "payment/pay?draw=$draw&quantity=$quantity&fname=$fname&lname=$lname&phone=$phone&email=$email";
$cancelUrl = SITE_URL . "payment/pay?success=false";

$redirectUrls = new redirectUrls();
$redirectUrls->setReturnUrl($successUrl)
    ->setCancelUrl($cancelUrl);

$payment = new Payment();
$payment->setIntent('sale')
    ->setPayer($payer)
    ->setRedirectUrls($redirectUrls)
    ->setTransactions([$transaction]);

try {
    $payment->create($apiContext);
} catch (Exception $e) {
    $e->getCode();
    $e->getData();
}

$approvalUrl = $payment->getApprovalLink();

header("Location: {$approvalUrl}");

处理完checkout.php后，我希望它会转到我的pay.php页，如下所示，然后在经过完整确认后从该页面退回。

use PayPal\Api\Payment;
use PayPal\Api\PaymentExecution;

include '../src/func/pay.php';
include '../src/func/manage.php';
require 'start.php';
require_once '../vendor/autoload.php';

$paymentId = filter_input(INPUT_GET, "paymentId", FILTER_DEFAULT);
//$success = filter_input(INPUT_GET, "success", FILTER_DEFAULT);
$success = TRUE;
$drawID = filter_input(INPUT_GET, "draw", FILTER_DEFAULT);
$wrong = filter_input(INPUT_GET, "wrong", FILTER_DEFAULT);
$sold = filter_input(INPUT_GET, "sold", FILTER_DEFAULT);
$quantity = filter_input(INPUT_GET, "quantity", FILTER_DEFAULT);
$token = filter_input(INPUT_GET, "token", FILTER_DEFAULT);
$payerID = filter_input(INPUT_GET, "PayerID", FILTER_DEFAULT);
$phone = filter_input(INPUT_GET, "phone", FILTER_DEFAULT);
$fname = filter_input(INPUT_GET, "fname", FILTER_DEFAULT);
$lname = filter_input(INPUT_GET, "lname", FILTER_DEFAULT);
$email = filter_input(INPUT_GET, "email", FILTER_DEFAULT);
$title = getTitle($drawID);
$ticketsLeft = ticketsLeft($drawID);
$paymentFeedback = "";
$tableNumbers = "";

if(!isset($success) || !isset($drawID)){
    header("Location: ../index.php#draw");
}

if($success = true){
    $paymentFeedback = "Thanks for purchasing your ticket(s).";
} else {
    $paymentFeedback = "Sorry, an error occured. Please try again.";
}

if($wrong == true) {
    $paymentFeedback = "You selected a wrong answer and cannot process further. Please try again later.";
    header("Location:" . SITE_URL . "payment/pay-complete?text=" . $paymentFeedback . "#entry");
}

if($sold == true && $wrong = false || $ticketsLeft <= 0){
    $paymentFeedback = "Sorry, all tickets have now sold out. Check out our other competitions";
    header("Location:" . SITE_URL . "payment/pay-complete?text=" . $paymentFeedback . "#entry");
}

$payment = Payment::get($paymentId, $apiContext);

$execute = new PaymentExecution();
$execute->setPayerId($payerID);

try {
    $result = $payment->execute($execute, $apiContext);
} catch(Exception $e) {
    $data = json_decode($e->getData());
    echo $data->message;
}

一个不相关的问题是，人们实际上在加载网站时遇到了问题，但是每次在桌面和移动设备上完美加载时都会出现问题。即使在删除缓存之后。

先谢谢大家。非常感谢您的帮助。

为什么有些使用付款程序可以正常进行，而另一些使用则会引发错误？
