我是小白貝寶和PHP，所以我跟着這個教程在線：https://www.developphp.com/video/PHP/PayPal-IPN-PHP-Instant-Payment-Notification-Script貝寶IPN沒有連接到我的數據庫中插入交易
我的問題是，我的IPN結果都不錯，但我ipn.php腳本將不會連接到我的數據庫，以便我可以存儲結果。
IPN.PHP CODE
<?php
//connect to the database
include_once ('includes/connect_to_mysql.php');
// Check to see there are posted variables coming into the script
if ($_SERVER['REQUEST_METHOD'] != "POST") die ("No Post Variables");
// Initialize the $req variable and add CMD key value pair
$req = 'cmd=_notify-validate';
// Read the post from PayPal
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// Now Post all of that back to PayPal's server using curl, and validate everything with PayPal
// We will use CURL instead of PHP for this for a more universally operable script (fsockopen has issues on some environments)
$url = "https://www.sandbox.paypal.com/cgi-bin/webscr"; //USE SANDBOX ACCOUNT TO TEST WITH
//$url = "https://www.paypal.com/cgi-bin/webscr"; //LIVE ACCOUNT
$curl_result=$curl_err='';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded", "Content-Length: " . strlen($req)));
curl_setopt($ch, CURLOPT_HEADER , 0);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$curl_result = @curl_exec($ch);
$curl_err = curl_error($ch);
curl_close($ch);
$req = str_replace("&", "\n", $req); // Make it a nice list in case we want to email it to ourselves for reporting
// Check that the result verifies with PayPal
if (strpos($curl_result, "VERIFIED") !== false) {
$req .= "\n\nPaypal Verified OK";
mail("[email protected]", "Verified OK", "$req", "From: [email protected]");
} else {
$req .= "\n\nData NOT verified from Paypal!";
mail("[email protected]", "IPN interaction not verified", "$req", "From: [email protected]");
exit();
}

我進一步調試的代碼到一個事實，即我的select語句沒有返回這對我表示到數據庫連接後沒有任何價值。
任何人都可以幫助我，爲什麼我不能使用ipn.php代碼連接到我的數據庫？我的網站的所有其他頁面將使用除此頁面以外的相同代碼進行連接，因此我只能認爲它與PayPal呼叫此頁面而不是我的服務器有關。
這裏是connect_to_mysql.php我的連接代碼：
<?php
/* PHP Database Connection */
$servername = "localhost";
$username = "user";
$password = "passs";
$database = "database";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $database);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>
mysql已棄用。使用mysqli或PDO。 –
是的，謝謝。一旦所有設置和工作都完成，我打算切換到mysqli，以免使調試過程複雜化。 – Neeeewb
