带测试形式的IPN监听器（PHP）

Question

我是php的新手，已经在我的IPN页面上工作了很长时间。

我必须完全恢复基础，并遵循本指南。 https://www.angelleye.com/test-paypal-ipn/

在第1阶段：我已经复制了HTML表单，因此我可以测试我的IPN页面。 它在指南"Notice that the action of the form is set to the URL you would configure for PayPal to hit for IPN. This way, you can load the form in a browser and submit it directly, which will display the result on screen including any errors that may occur. This can help to find any problems with the script and eliminate them early in the process＆＃34;

中说明

我根本没有收到任何错误消息，但脚本没有将值添加到数据库中，尽管查询肯定有效

以下是我为测试而复制的表单：

以下是IPN页面代码：

<?php
include 'connect.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.sanpaypal.com/cgi-bin/webscr');

// In wamp like environments that do not come bundled with root authority certificates,

// 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);

                    }else{
                    die('Error : ('. $mysqli->errno .') '. $mysqli->error);

                    $statement->close();
