Question

我试图捕获订阅者ID。一旦客户端订阅并发送到ipn页面，订阅者ID就不会回显！

<?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 ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

    // assign posted variables to local variables



      ////////////////////////////////////////////HERE
    $payer_id= $_POST['subscr_id'];
      echo 'id='.$payer_id;


      ///////////////////////////////////////////



    $item_number = $_POST['item_number'];
    $payment_status = $_POST['payment_status'];
    $payment_amount = $_POST['mc_gross'];
    $payment_currency = $_POST['mc_currency'];
    $txn_id = $_POST['txn_id'];
    $receiver_email = $_POST['receiver_email'];
    $payer_email = $_POST['payer_email'];
      if("subscr_cancel" == $_POST['txn_type']){

    if (!$fp) {
    // HTTP ERROR
    } else {
    fputs ($fp, $header . $req);
    while (!feof($fp)) {
    $res = fgets ($fp, 1024);
    if (strcmp ($res, "VERIFIED") == 0) {
    // check the payment_status is Completed
    // check that txn_id has not been previously processed
    // check that receiver_email is your Primary PayPal email
    // check that payment_amount/payment_currency are correct
    // process payment

                     $websites= "websites";
        $database = "k29803_1";
       mysql_connect("localhost", $username, $password) or die(mysql_error());
       mysql_select_db($database);

      $query = "SELECT * FROM users WHERE username= secret AND password = secret ";
      $results = mysql_query($query)or die(mysql_error());
        if(mysql_num_rows($results)==1){
            $add_credits = "UPDATE users SET credits = credits -5000
            WHERE username= 'drahoslava' AND password = 'drah0slava'";
            mysql_query($add_credits) or die(mysql_error());


          }

    }
    else if (strcmp ($res, "INVALID") == 0) {
    // log for manual investigation
    }
    }
    fclose ($fp);
    }
      }
      ?>

按钮看起来像这样

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="NQMGM2LCZUQRE">

  <input type="hidden" name="item_name" value="1" />
    <input type="hidden" name="item_number" value="01" />
    <input type="hidden" name="amount" value="1.99" />
    <input type="hidden" name="currency_code" value="USD" />
<input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_subscribeCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
<img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>

如何让订阅ID回显？按钮有问题吗？它应该有notify_url吗？

这是我回复的内容

Answer 1

您要回发的内容不是IPN数据。您需要在PayPal表单中设置notify_url才能接收IPN数据。

<input type="hidden" name="notify_url" value="http://www.germcode.kodingen.com/ipn.php">

注意：如果您使用的是所谓的“托管按钮”（所有详细信息都与PayPal一起存储），您还可以在PayPal配置文件中设置IPN，或者转到按钮管理工具，单击步骤3，勾选“添加高级变量”并在textarea中添加notify_url=http://www.germcode.kodingen.com/ipn.php。

这是用IPN捕获paypals用户ID的正确方法吗？
