</form> 

在我沒有得到任何值，我notify_url頁我得到的價值爲

session_start(); 
require("ipn_cls1.php"); 
$paypal_info = $_POST; 
print_r($paypal_info); 
$paypal_ipn = new paypal_ipn($paypal_info); 
$payment_status = trim($paypal_info['payment_status']); // Si Completed : tout est OK echo 
$payment_amount = trim($paypal_info['mc_gross']); 

Answer 1

我在我當前的項目中有與貝寶自適應付款相同的問題。我已將

notify_url設爲http://mysite.com/payment-success。在這個頁面中，我簡單地編碼了

$ request = $ _POST;

郵件（ '身份識別碼@我的賬戶'，$要求提供）;

然後我把交易結果到我的郵箱查看。

請注意，在我的郵件中，我可以看到交易結果，如果我插入到數據庫中，它將插入但我無法在我的頁面中看到交易結果。嘗試向您的郵件發送交易結果。

創建paypal_ipn.php文件並在其中放置php代碼。

// 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']; 
    $data['invoice']   = $_POST['invoice']; 
    $data['paypallog']   = $req; 

    // 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) . "\r\n\r\n"; 
    $fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30); 

    if (!$fp) { 
     // HTTP ERROR 
    } else {  


     fputs ($fp, $header . $req); 
     while (!feof($fp)) { 
      ////mail('atiftariq80@gmail.com','Step 9','Step 9');   
      $res = fgets ($fp, 1024); 
      if (true || strcmp($res, "VERIFIED") == 0) { 
       ////mail('atiftariq80@gmail.com','PAYMENT VALID','PAYMENT VALID'); 

      // Validate payment (Check unique txnid & correct price) 
      $valid_txnid = check_txnid($data['txn_id']); 
      $valid_price = check_price($data['payment_amount'], $data['item_number']); 
      // PAYMENT VALIDATED & VERIFIED! 
      if($valid_txnid && $valid_price){    
      //----------------- INSERT RECORDS TO DATABASE------------------------------------- 
      if ($data['invoice']=='basic') { 
       $price = 39; 
      } else { 
       $price = 159; 
      } 
      $this->user_model->update_user(
       array(
        'id' => $data['custom'], 
        'user_status' => 1, 
        'payment_date' => date("Y-m-d H:i:s",time()), 
        'next_payment_date' => date('Y-m-d', strtotime('+32 days')), 
        'user_package' => $data['invoice'], 
        'package_price' => $price 
       ) 
      ); 
      $data2 = array('id' => '', 
      'txn_id' => $data['txn_id'], 
      'amount' => $data['payment_amount'], 
      'mode ' => $data['payment_status'], 
      'paypal_log' => $data['paypallog'], 
      'user_id' => $data['custom'], 
      'created_at' => date('Y-m-d H:i:s',time()) 

      ); 
      $this->db->insert('tbl_paypal_log', $data2); 
      //----------------- INSERT RECORDS TO DATABASE------------------------------------- 
      }else{     
      // Payment made but data has been changed 
      // E-mail admin or alert user 
      }      

     } elseif ($res=='INVALID') { 

       // PAYMENT INVALID & INVESTIGATE MANUALY! 
       // E-mail admin or alert user 
       ////mail('atiftariq80@gmail.com','PAYMENT INVALID AND INVESTIGATE MANUALY','PAYMENT INVALID AND INVESTIGATE MANUALY'); 

     }  
     }  
    fclose ($fp); 
    }

有一個really good guide到即時付款通知（IPN），並理解它們是如何工作的。本指南爲您提供了使您的notify_url正常工作所需的步驟。

有貝寶提供的good code samples爲您做驗證回覆，這真的很不錯。你可以使用這些是你自己的起點。
