【问题描述】：

我已经在这里工作了很长时间，从这里阅读了无数的教程、指南等，但没有运气！

我在我的网站上设置了一个贝宝购买按钮。使用 Paypal 的沙箱对此进行了测试后，付款部分可以正常工作。然而，在返回网站时，它并没有给用户他们购买的东西！

这是在他们可以选择购买的页面上：

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
    <input type="hidden" name="cmd" value="_xclick">
    <input type="hidden" name="custom" value="<?=$person?>">
    <input type="hidden" name="business" value="[e-mail]">
    <input type="hidden" name="item_name" value="5000 Credits for <?=$person?>">
    <input type="hidden" name="item_number" value="5000 Credits">
    <input type="hidden" name="amount" value="5.00">
    <input type="hidden" name="no_shipping" value="1">
    <input type="hidden" name="no_note" value="0">
    <input type="hidden" name="currency_code" value="USD">
    <input type="hidden" name="notify_url" value="<?=$site[location]?>ipn.php">
    <input type="hidden" name="return" value="<?=$site[location]?>creditsdone.php">
    <input type="hidden" name="cancel_return" value="<?=$site[location]?>">
    <input src="images/buy_button.gif"  type="image"  name="submit" >
</form>

creditsdone.php 只是说“感谢您的购买”。这有效，因为您在购买成功后会返回此内容。

但是 ipn.php 页面不起作用。在返回网站时，不会向玩家帐户添加任何积分。

ipn.php页面如下：

<?
include("funcs.php"); 


// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value) 
  $value = urlencode(stripslashes($value));
  $req .= "&$key=$value";


// 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 ('www.paypal.com', 80, $errno, $errstr, 30);

// assign posted variables to local variables
// note: additional IPN variables also available -- see IPN documentation
/*$item_name = $_POST['item_name'];
$receiver_email = $_POST['receiver_email'];
$item_number = $_POST['item_number'];
$invoice = $_POST['invoice'];
$payment_status = $_POST['payment_status'];
$payment_gross = $_POST['payment_gross'];
$txn_id = $_POST['txn_id'];
$payer_email = $_POST['payer_email'];
*/
if (!$fp) 
  // ERROR
  echo "$errstr ($errno)";
 else 
  fputs ($fp, $header . $req);
  while (!feof($fp)) 
    $res = fgets ($fp, 1024);
    if (strcmp ($res, "VERIFIED") == 0) 
        echo "<pre>";
        print_r($_POST);
        if($_POST[payment_status]=="Completed") 

if ((!fetch("SELECT tranid FROM $tab[paypal] WHERE tranid='$txn_id';")) && ($business == "[e-mail]"))
   

$subexpire = time()+864000;

    if($payment_gross == "5.00")$turns="5000";
elseif($payment_gross == "10.00")$turns="7250";
elseif($payment_gross == "25.00")$turns="10000";
elseif($payment_gross == "50.00")$turns="12500";
elseif($payment_gross == "100.00")$turns="25000";

elseif($payment_gross == "1000.00")$turns="400000";
elseif($payment_gross == "15000.00")$turns="700000";

else$turns="0";

        $expires=$time+864000;//10 days 
        $total=$payment_gross-$payment_fee;

//update database to add turns to user in game they bought for
        mysql_query("UPDATE $tab[user] SET status='supporter', statusexpire='$expires', credits=credits+$turns WHERE username='$custom'");

//insert into database paypal information
        $buying_user = mysql_fetch_array(mysql_query("SELECT * FROM users WHERE username = '". $custom ."'"));

        $time = time();
        $fetch_the_games = mysql_query("SELECT * FROM games WHERE starts < $time AND ends > $time");
        while($credit_games = mysql_fetch_array($fetch_the_games))
        
            mysql_query("UPDATE r$credit_games[round]_pimp SET status = '". supporter ."' WHERE code = '". $buying_user[code] ."'");
        
        mysql_query("INSERT INTO $tab[paypal] (tranid,amount,fee,user,datebought) VALUES ('$txn_id','$payment_gross','$payment_fee','$custom','$time');");
//send email to admin about transaction from paypal--ADMIN-check database to make sure transaction went through to game
        mail_2("$turns credits where bought!","\nDear Admin,\n\nYou just received a payment from $custom for $turns credits\n\nCost: $$payment_gross\nFee: $$payment_fee\n----------\nTotal: $$total","[e-mail]");

   elseecho"Cannot refresh transaction!";

        
      // check the payment_status is Completed
      // check that txn_id has not been previously processed
      // check that receiver_email is an email address in your PayPal account
      // process payment
      
      else if (strcmp ($res, "INVALID") == 0) 
      // log for manual investigation
      
  
  fclose ($fp);

?>

我知道这看起来很混乱，我对 php 很陌生，完全被卡住了，所以任何帮助或提示将不胜感激！

谢谢！

【问题讨论】：

你为调试ipn.php做了什么？确认它的命中，确认值，确认数据库查询...

在testing PayPal IPN 上查看本指南，您应该能够找到您的问题。

谢谢安德鲁，我会看看。另外，对不起，Dagon，我对编码很陌生。我从不久前购买的一个脚本中获得了上述内容，并且在我自学 php 时一直在慢慢添加它。我了解基础知识，但上面的代码有点过头了！我不太清楚你所说的调试 ipn.php 是什么意思？

您需要学习 50 多种可能性来调试、回显和检查每个变量、每个查询

【参考方案1】：

问题来了

mysql_query("UPDATE r$credit_games 

改成

 mysql_query("UPDATE credit_games

或任何您的查询名称。

一定是 credit_games 你给 $ 的错误，所以请暂停一下，睡几个小时，然后继续工作，呵呵。

【讨论】：

不，因为他使用来自 IPN 的返回值而不是返回 url

我想我在这里找到了错误 mysql_query("UPDATE r$credit_games it must be credit_games you have a $giving error

谢谢罗德里戈，我再试一次！
