Я недавно использовал это руководство:
http://www.evoluted.net/thinktank/web-development/paypal-php-integration
и я понял, что он правильно идет на веб-сайте paypal, и когда платеж сделан – он перенаправляется на страницу «успешный платеж».
проблема в том, что она не делает «payment.php часть ответа», поэтому она не добавляет платеж в базу данных.
Вот код payment.php
<?php // Database variables $host = "localhost"; //database location $user = "xxx"; //database username $pass = "xxx"; //database password $db_name = "xxx"; //database name // PayPal settings $paypal_email = 'sawickipiotr2000-facilitator-1@gmail.com'; $return_url = 'http://leagueaccountsbot.tk/elements/payment-successful.html'; $cancel_url = 'http://leagueaccountsbot.tk/elements/payment-cancelled.html'; $notify_url = 'http://leagueaccountsbot.tk/elements/payments.php'; $item_name = 'League Accounts Bot'; $item_amount = 5.00; // Include Functions include("functions.php"); // Check if paypal request or response if (!isset($_POST["txn_id"]) && !isset($_POST["txn_type"])){ $querystring = ''; // Firstly Append paypal account to querystring $querystring .= "?business=".urlencode($paypal_email)."&"; // Append amount& currency (£) to quersytring so it cannot be edited in html //The item name and amount can be brought in dynamically by querying the $_POST['item_number'] variable. $querystring .= "item_name=".urlencode($item_name)."&"; $querystring .= "amount=".urlencode($item_amount)."&"; //loop for posted values and append to querystring foreach($_POST as $key => $value){ $value = urlencode(stripslashes($value)); $querystring .= "$key=$value&"; } // Append paypal return addresses $querystring .= "return=".urlencode(stripslashes($return_url))."&"; $querystring .= "cancel_return=".urlencode(stripslashes($cancel_url))."&"; $querystring .= "notify_url=".urlencode($notify_url); // Append querystring with custom field //$querystring .= "&custom=".USERID; // Redirect to paypal IPN header('location:https://www.sandbox.paypal.com/cgi-bin/webscr'.$querystring); exit(); } else { //Database Connection $link = mysql_connect($host, $user, $pass); mysql_select_db($db_name); // Response from Paypal // read the post from PayPal system and add 'cmd' $req = 'cmd=_notify-validate'; foreach ($_POST as $key => $value) { $value = urlencode(stripslashes($value)); $value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix $req .= "&$key=$value"; } // assign posted variables to local variables $data['item_name'] = $_POST['item_name']; $data['item_number'] = $_POST['item_number']; $data['payment_status'] = $_POST['payment_status']; $data['payment_amount'] = $_POST['mc_gross']; $data['payment_currency'] = $_POST['mc_currency']; $data['txn_id'] = $_POST['txn_id']; $data['receiver_email'] = $_POST['receiver_email']; $data['payer_email'] = $_POST['payer_email']; $data['custom'] = $_POST['custom']; // post back to PayPal system to validate $header = "POST /cgi-bin/webscr HTTP/1.0\r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Content-Length: " . strlen($req) .

Или, возможно, я сделал что-то неправильно в настройках PayPal учетной записи? Я установил IPN на « http://www.leagueaccountsbot.tk/elements/payments.php », и после успешной оплаты эта страница: «/elements/successful.html?amt=5.00&cc=USD&item_name=League%20Accounts % 20Bot & ITEM_NUMBER = 1 & й = Завершенный & Тх = 4KG186895E5344708"
