问题描述
因此，在我的网站上，人们可以通过单击立即付款"来订购他们想要的升级并在框中输入他们的用户名.到目前为止，我会进入 PayPal，查看付款，查看 Minecraft 用户名字段，然后手动升级.现在我想开始使用 IPN，这样我就可以自动化我一直在做的所有工作.
这是升级选项的 HTML 代码:
<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="W2RH7VA3YS3Y4"><表格><tr><td width=75%><h2>自定义地图 - $5.00</h2></td><td><input type="hidden" name="on0" value="Minecraft Username">Minecraft Username<input type="text" name="os0" maxlength="200"></td></tr><tr><td>上传您想玩的任何地图的能力！也许是生存岛地图?你打赌！或者饥饿游戏！</td><td><input type="submit" class="btn btn-primary" value="Buy Now" border="0" name="submit" alt="PayPal - 更安全、更简单的在线支付方式！"></td></tr></表单>这里是 PHP 代码，可以简单地向我发送一封电子邮件，其中包含我需要尝试使其正常工作的信息:
我遇到的问题是:
$custom = $_POST['on0'];我按照上面的方法尝试过，并且:
$custom = $_POST['custom'];第一个是因为这是 Minecraft Username 字段的名称，第二个我尝试了因为我读到它应该是这样，但无论哪种方式它都没有返回任何内容.任何帮助都会很棒！谢谢！
转储 $_POST 的结果并查看哪个键适合您正在寻找的值.使用 var_dump 或 print_r
//显示值类型等更多细节var_dump($_POST);//只显示 key =>数组的值关系打印_r($_POST);编辑
我刚刚意识到使用 ipn 无法看到此输出.在这种情况下，您始终可以序列化整个 $_POST 数组并通过电子邮件发送.
$post_data_string = serialize($_POST);邮件('[email protected]', 'PayPal IPN', $post_data_string);So on my website, people are able to order upgrades by clicking "Pay Now" for the upgrade they want and by entering their username in the box. Up until now, I would then go in to PayPal, see the payment, and look at the Minecraft Username field, and upgrade it by hand. Now I want to start using IPN so that I can automate all of the work that i've been doing.
Here is the HTML code for a upgrade option:
<div class=donationBox>
<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="W2RH7VA3YS3Y4">
<table>
<tr>
<td width=75%><h2>Custom Maps - $5.00</h2></td>
<td><input type="hidden" name="on0" value="Minecraft Username">Minecraft Username<input type="text" name="os0" maxlength="200"></td>
</tr>
<tr>
<td>The ability to upload any map you want to play on! Maybe a survival island map? You bet! Or the Hunger Games!</td>
<td><input type="submit" class="btn btn-primary" value="Buy Now" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!"></td>
</tr>
</table>
</form>
</div>
And here is the PHP code to simply send me an Email with the info I need to try to get it working:
<?php
// STEP 1: Read POST data
// reading posted data from directly from $_POST causes serialization
// issues with array data in POST
// reading raw POST data from input stream instead.
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
$keyval = explode ('=', $keyval);
if (count($keyval) == 2)
$myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
$get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
$value = urlencode(stripslashes($value));
} else {
$value = urlencode($value);
}
$req .= "&$key=$value";
}
// STEP 2: Post IPN data back to paypal to validate
$ch = curl_init('https://www.paypal.com/cgi-bin/webscr');
curl_setopt($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);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
// In wamp like environments that do not come bundled with root authority certificates,
// please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set the directory path
// of the certificate as shown below.
// curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
if( !($res = curl_exec($ch)) ) {
// error_log("Got " . curl_error($ch) . " when processing IPN data");
curl_close($ch);
exit;
}
curl_close($ch);
// STEP 3: Inspect IPN validation result and act accordingly
if (strcmp ($res, "VERIFIED") == 0) {
// check whether 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
// assign posted variables to local variables
$item_name = $_POST['item_name'];
$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'];
$custom = $_POST['on0'];
$message = "An order has been IPNified! " . $item_name . " " . $item_number . " " . $payment_amount . " " . $txn_id . " " . $custom;
mail('[email protected]', 'PayPal IPN', $message);
} else if (strcmp ($res, "INVALID") == 0) {
mail('[email protected]', 'PayPal IPN', 'Errors');
}
?>
The problem that I'm having is here:
$custom = $_POST['on0'];
I tried it as the above and:
$custom = $_POST['custom'];
The first one because that's the name of the Minecraft Username field, and the second I tried because I read that's what it should be, but either way it just didn't return anything. Any help would be great! Thanks!
Dump the results of $_POST and see which key fits the values you're looking for. Use either var_dump or print_r
// Displays more detail such as value types
var_dump($_POST);
// Only displays key => value relationships of an array
print_r($_POST);
EDIT
I just realized it's not possible to see the output of this using ipn. In this case you can always serialize the entire $_POST array and send it in an email.
$post_data_string = serialize($_POST);
mail('[email protected]', 'PayPal IPN', $post_data_string);
