개인 웹 사이트에서 첫 번째 PayPal 익스프레스 체크를 학습 목적으로 사용하고 있으며 Express 체크 아웃이 어떻게 구축되었는지 설명하는 온라인 튜토리얼을 발견했습니다. 이 자습서에서 사용할 수있는 샘플 페이지를 사용하여 더 나은 이해를 얻으 려하지만 오류 : PaymentAction : Required 매개 변수가 누락되어 문제를 추적하지 못하는 것 같습니다.PaymentAction Error 받기
그래서 PaymentAction 매개 변수를 보내야하고 판매로 보내야한다는 것을 이해합니다. 나는 왜 내가 그것을 보내지 않는다고 말하는지 이해하지 못한다. 누군가 코딩의 오류를 잡아낼 수 있기를 바랍니다. 또는이 문제의 원인에 대해 제안 할 수 있기를 바랍니다.
$ paymentType은 아래 코드에서 사용되는 다른 변수와 함께 config.php에 저장됩니다.
이 내 $의 paymentType 내 config.php에의 모습입니다 :
$ paymentType = '판매'; // 지불 유형
<?php
session_start();
include_once("config.php");
include_once("paypal.class.php");
include ("../inc/settings.php");
$paypalmode = ($PayPalMode=='sandbox') ? '.sandbox' : '';
if($_POST) //Post Data received from product list page.
{
//Mainly we need 4 variables from product page Item Name, Item Price, Item Number and Item Quantity.
//Please Note : People can manipulate hidden field amounts in form,
//In practical world you must fetch actual price from database using item id. Eg:
//$ItemPrice = $mysqli->query("SELECT item_price FROM products WHERE id = Product_Number");
// Connect to DB
mysql_connect($server, $user, $pass) or die(mysql_error());
mysql_select_db($name) or die(mysql_error());
// Get the item price from the database
$result = mysql_query("SELECT * FROM admin_settings");
while($row = mysql_fetch_array($result)) {
// Check how many credits they are buying
if ($_POST["itemnumber"] == 5) {
$ItemPrice = $row['five_credits'];

변수 대신 판매 단어를 입력했는데 작동하지 않았습니다. 정상적인 파일에서 선언했지만 작동하지 않았습니다. 화면에 $ paymentType을 인쇄하면 판매로 표시됩니다. 직접 코드를 작성하는 방법을 가르쳐주는 더 나은 튜토리얼을 발견 했으므로이 답변을 더 이상 필요하지 않습니다. – user3340895
