[hasajacykacperek]

Hello, i added PHP SDK from my payment to modules/gateways

https://github.com/pay-now/paynow-php-sdk

and added code to new file:

<?php

if (!defined("WHMCS")) die("This file cannot be accessed directly");

require_once('vendor/autoload.php');

use Paynow\Client;
use Paynow\Environment;
use Paynow\Exception\PaynowException;
use Paynow\Service\Payment;

function paynow_config() {
    $version = '1.0.0';
    $configarray = array(
     "FriendlyName" => array("Type" => "System", "Value"=>"PayNow"),
     "userid" => array("FriendlyName" => "Identyfikator Punktu Płatności", "Type" => "text", "Size" => "20"),  
     "userkey" => array("FriendlyName" => "Klucz Punktu Płatności", "Type" => "text", "Size" => "20"),
     "buttontext" => array("FriendlyName" => "Tekst Przycisku", "Type" => "text", "Value"=>"Zapłać z paynow", "Size" => "20"),
     "Wersja" => array( "Type" => "html", "Size" => "25", "Description" => $version)
    );

	return $configarray;
}

function paynow_link($params) {
    $client = new Paynow\Client('xd', 'xd', Paynow\Environment::SANDBOX);
    $orderReference = "success_whmcs_".$params['invoiceid'];
    $idempotencyKey = uniqid($orderReference . '_');

    $paymentData = [
        "amount" => $params['amount'],
        "currency" => "PLN",
        "externalId" => $orderReference,
        "description" => $params["description"],
        "buyer" => [
            "email" => $params['clientdetails']['email'],
            'firstName' => $params['clientdetails']['firstname'],
            'lastName' => $params['clientdetails']['lastname']
        ]
    ];

    try {
        $payment = new Payment($client);
        $result = $payment->authorize($paymentData, $idempotencyKey);

        $code = '<a href="'.$result->getRedirectUrl().'">'.$params['buttontext'].'</a>';
        return $code;

    } catch (PaynowException $exception) {
        var_dump($exception);
        return "wystapil bardzo dziwny blad ktorego pewnie nie da sie naprawic XD";
    }
}
