我们有一个网站，里面有一些数字商品。从那里购买的用户需要使用BTC购买一些信用卡。在他购买信用卡后，脚本必须用他用BTC购买的货币金额（美元）加载他的账户。

所以这里我们有HTML表单：

    <form name="bitcoin" method="post" action="btc.php">
<strong><font color="grey">$</font></strong>
<input name="member" value="<?php echo $_SESSION['gdusername'];?>" type="hidden">
<input name="amount" size="10" value="" type="text">
<input name="btnPMPay" id="btnPMPay" value="Add Balance" type="submit">
</form>

这里我们有一个PHP代码，它可以发挥所有的魔力，好吧，至少这是它应该做的

    <?php
error_reporting(1);
include "inc/config.php";
include "inc/pagenavigation.php";
include "functions.php";
if (!checkLoggedin())
{
    header("Location: login.html");
    exit;
}
// config Blockchain account
$btc = 246; //BTC Value
$guid = '37587730-e97e-4349-8451-4fa9d38119a5';  // Blockchain account
$main_password = 'Mypassword'; // Blockchain passs
$rate = 246; //BTC Rate

$amount=$_POST['amount'];
$uid = mysql_real_escape_string($_SESSION['gdusername']); //
$result = mysql_query("SELECT credit FROM t2_user WHERE username='$uid'") or die("ERROR! CONTACT SUPPORT!");
$row = mysql_fetch_row($result);
$credit = $row[0];
$uid = mysql_real_escape_string($_SESSION['gdusername']);
$ip = mysql_real_escape_string(VisitorIP());
$url = "https://blockchain.info/merchant/$guid/new_address?password=$main_password&label=$uid";
if (isset($_POST['amount'])){
    $_SESSION['USD_amount'] = $_POST['amount'];
    $_SESSION['BTC_amount'] = number_format($_SESSION['USD_amount']/$rate, 8, '.', '');
    $temp = _curl($url, '', '');
    $_SESSION['BTC_Address'] = get_string_between($temp, 'address":"', '"');    
}
if (!isset($_SESSION['USD_amount']) || $_SESSION['USD_amount'] < 5)
    die("Minimum payment 5$");
if (isset($_POST['bitcoin']))
{
    $a = $_SESSION['BTC_Address'];
    $url = "https://blockchain.info/q/addressbalance/$a?confirmations=0";
    $page = _curl($url, '', '');
    if ($page > 0) {
        $amount = $page/100000000;
        if($amount>= $_SESSION['BTC_amount']){
        $y = $_SESSION['USD_amount'];
              $x = $credit+$y;
            $sql = "UPDATE t2_user SET credit=$x WHERE username='$uid'";
            mysql_query($sql);
            $messages = '<font color=green>Payment Completed!</font> => <a href="http://pentagon.al/shop/index.php">Go Back</a>';
            unset($_SESSION['USD_amount']);
        }else $messages = "<font color=red>Error Payment.Contact Support</font>";
    }else $messages = "<font color=red>Error Payment Not Received. Contact Support tickets</font>";

我的问题是这个PHP脚本没有完成以下操作。

  1. 不询问区块链以查看是否进行了转账，尽管当用户按下确认按钮时有0个确认
  2. 在客户点击确认按钮后，不会将其购买的信贷更新到数据库中
  3. 即使我输入了高于5美元的金额，他仍然不断告诉我最低付款金额是5美元

有人能帮我吗？

if语句后面没有大括号。我想你的剧本在这一点上一直在消亡，告诉你"最低付款5美元"？

if (!isset($_SESSION['USD_amount']) || $_SESSION['USD_amount'] < 5)
die("Minimum payment 5$");

此外，你在区块链上的GUID是敏感信息，你不应该发布。这可能会导致有人试图通过恢复钱包功能拿走你的资金。

不知道你能获得多少流量，但你的blockchain.info钱包将在1000个地址后达到最大流量。

也不是这样。不管怎样，我把这个修好了。

if (!isset($_SESSION['USD_amount']) || $_SESSION['USD_amount'] < 5)
    die("Minimum payment 5$");

本应包含在这一中

if (isset($_POST['amount'])){
    $_SESSION['USD_amount'] = $_POST['amount'];
    $_SESSION['BTC_amount'] = number_format($_SESSION['USD_amount']/$rate, 8, '.', '');
    $temp = _curl($url, '', '');
    $_SESSION['BTC_Address'] = get_string_between($temp, 'address":"', '"');    
}

现在，脚本正确地检查btc数量并返回正确的结果。

下一个dilema是为什么它不询问创建的地址，以查看特定的金额是否已发送到它。如果它已发送并有多个确认>=0执行此

if (isset($_POST['bitcoin']))
{
    $a = $_SESSION['BTC_Address'];
    $url = "https://blockchain.info/q/addressbalance/$a?confirmations=0";
    $page = _curl($url, '', '');
    if ($page > 0) {
        $amount = $page/100000000;
        if($amount>= $_SESSION['BTC_amount']){
        $y = $_SESSION['USD_amount'];
              $x = $credit+$y;
            $sql = "UPDATE t2_user SET credit=$x WHERE username='$uid'";
            mysql_query($sql);
            $messages = '<font color=green>Payment Completed!</font> => <a href="http://my.url/index.php">Go Back</a>';
            unset($_SESSION['USD_amount']);
        }else $messages = "<font color=red>Error Payment.Contact Support</font>";
    }else $messages = "<font color=red>Error Payment Not Received. Contact Support tickets</font>";
}

我仔细检查了一下，服务器有权使用API来询问它，但没有响应。

在脚本的末尾，当按下确认按钮（<input type="hidden" id="bitcoin" name"bitcoin">）时，这个_curl函数应该被触发吗

    <?

function _curl($url, $post = "", $sock, $usecookie = false)
{
    $ch = curl_init();
    if ($post) {
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    }
    if (!empty($sock)) {
        curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, true);
        curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
        curl_setopt($ch, CURLOPT_PROXY, $sock);
    }
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_USERAGENT,
        "Mozilla/6.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3");
    if ($usecookie) {
        curl_setopt($ch, CURLOPT_COOKIEJAR, $usecookie);
        curl_setopt($ch, CURLOPT_COOKIEFILE, $usecookie);
    }
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}
function get_string_between($string, $start, $end)
{
    $string = " " . $string;
    $ini = strpos($string, $start);
    if ($ini == 0)
        return "";
    $ini += strlen($start);
    $len = strpos($string, $end, $ini) - $ini;
    return substr($string, $ini, $len);
}
function VisitorIP()
{ 
    if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    else $ip = $_SERVER['REMOTE_ADDR'];
    return trim($ip);
}
?>

有什么建议吗？
