notify.php
$value) { if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) { $value = urlencode(stripslashes($value)); } else { $value = urlencode($value); } $req .= "&$key=$value"; } if(USE_SANDBOX == true) { $paypal_url = "https://www.sandbox.paypal.com/cgi-bin/webscr"; } else { $paypal_url = "https://www.paypal.com/cgi-bin/webscr"; } $ch = curl_init($paypal_url); if ($ch == FALSE) { return FALSE; } curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); curl_setopt($ch, CURLOPT_POSTFIELDS, $req); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2); curl_setopt($ch, CURLOPT_FORBID_REUSE, 1); if(DEBUG == true) { curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLINFO_HEADER_OUT, 1); } curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close')); $res = curl_exec($ch); if (curl_errno($ch) != 0) { if(DEBUG == true) { error_log(date('[Y-m-d H:i e] ').

PHP_EOL, 3, LOG_FILE); } curl_close($ch); } $tokens = explode("\r\n\r\n", trim($res)); $res = trim(end($tokens)); if (strcmp ($res, "VERIFIED") == 0) { $product_name = $_POST['product_name']; $product_number = $_POST['product_number']; $subscription_status = $_POST['subscription_status']; $subscription_amount = $_POST['mc_gross']; $subscription_currency = $_POST['mc_currency']; $txn_id = $_POST['txn_id']; $receiver_email = $_POST['receiver_email']; $payer_email = $_POST['payer_email']; include("DBController.php"); $db = new DBController(); $issubscriptionCompleted = false; if($subscription_status == "Completed") { $issubscriptionCompleted = true; } $isUniqueTxnId = false; $param_type="s"; $param_value_array = array($txn_id); $result = $db->runQuery("SELECT * FROM subscription WHERE txn_id = ?",$param_type,$param_value_array); if(empty($result)) { $isUniqueTxnId = true; } if($issubscriptionCompleted) { $param_type = "sssdss"; $param_value_array = array($product_number, $product_name, $subscription_status, $subscription_amount, $subscription_currency, $txn_id); $subscription_id = $db->insert("INSERT INTO subscription(product_number, product_name, subscription_status, subscription_amount, subscription_currency, txn_id) VALUES(?, ?, ?, ?, ?, ?)", $param_type, $param_value_array); error_log(date('[Y-m-d H:i e] '). "Verified IPN: $req ". PHP_EOL, 3, LOG_FILE); } if(DEBUG == true) { error_log(date('[Y-m-d H:i e] '). "Verified IPN: $req ".
