    Default bitcoin payment gateway

    I need help to upgrade this old bitcoin api payment version to new version

    ================================================================
    Code:
    <?php
error_reporting(0); ini_set('display_errors', 0);
// auto rate
			$url_btc =    'https://blockchain.info/ticker';

						$response_btc = file_get_contents($url_btc);
						$object_btc = json_decode($response_btc);
							//print_r($object_btc);
							
						$usdprice = $object_btc->{"USD"}->{"last"};
						$rate['rate'] =  $object_btc->{"USD"}->{"last"};
// config Blockchain account
$btc = $rate['rate'];
$guid = 'd4f0f';  // Blockchain account
$main_password = 'passss'; // Blockchain pass
$second_password = ''; // Blockchain pass
$rate = $rate['rate'];

$result = $db->query("SELECT balance,amount_purchased FROM users WHERE username='$userid'") or die("ERROR! CONTACT SUPPORT!");
$row = $result->fetch_row();
$balance = $row[0];
$amountp = $row[1];
$ip = $db->real_escape_string(VisitorIP());
$url = "https://blockchain.info/merchant/$guid/new_address?password=$main_password&second_password=$second_password&label=$userid";
if (isset($_POST['amount'])){
    $_SESSION['USD_amount'] = $db->real_escape_string($_POST['amount']);
    $_SESSION['BTC_amount'] = number_format($_SESSION['USD_amount']/$rate+0.0010, 8, '.', '');
    $temp = _curl($url, '', '');
    $_SESSION['BTC_Address'] = get_string_between($temp, 'address":"', '"');  	
}
if (!isset($_SESSION['USD_amount']) || $_SESSION['USD_amount'] < 10)
    die("WRONG AMOUNT MINIMUM IS 10$");
if (!isset($_SESSION['USD_amount']) || $_SESSION['USD_amount'] > 5000)
    die("WRONG AMOUNT MAXIMUM IS 5000$");


if (isset($_POST['bitcoin']))
{
    $a = $db->real_escape_string($_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 = $db->real_escape_string($_SESSION['USD_amount']);
              $x = $balance+$y;
	      $c = $amountp + $y;
	    $btc_amount = $db->real_escape_string($_SESSION['BTC_amount']);
            $sql = "UPDATE users SET balance=$x, amount_purchased=$c WHERE username='$userid'";
            $db->query($sql);

            $sql2 = "INSERT INTO orders(amount,btc_amount,username,address,ip,method,date) VALUES('$y', '$btc_amount', '$userid','$a','$ip','Bitcoin',now())";
            $db->query($sql2);
            unset($_SESSION['USD_amount']);
		header("Location: success");
		die;
          }else { $failed = 1; 
		$messages = "<font size=2 color=red>Payment not yet completed, the amount you sent is too low . </font>"; }
    }else { $failed = 1;
		 $messages = "<font size=3 color=red>Payment not yet completed, No payment received .</font>"; }
}

    Default

    And what is the new version? Or what about this old script has stopped working? How should we know how to upgrade this script without knowing where it came from, server requirements, user requirements (e.g. a unique API key) or installation/upgrade instructions? And how are we to test this in own environment (full demo pack? DB structure?)?

    There are many questions to answer and unfortunately we can't really help you without you providing us with *lots* more information.

    At the end of the day, I'm not confident that DD is the place to get help for this script and certainly, with so little information, it is very unlikely that anyone will be able to provide help. This is one of those times where it may be better to go back to the source to see if they have updated their documentation or check if they have a help forum/support system of their own.

    By all means, please post back with more information, then our members can further assess if they can assist you with you problem.
