It is a simple PHP library that allow implement payment gateway methods out of the box.

Requirements

• PHP needs to be a minimum version of 5.4.0
• cURL needs to be enabled

Installation

1. git clone
2. composer install

How to use:

Library provides few already created methods like generate form order or just generate form fields.

If you want to generate full form:

1. First you need to initialize Payment instance and provide environment, service key and service id. The last parameter language is optional, if if won't be provided the default value will be used (which is 'en')
2. Then simply run $payment->buildOrderForm($orderData) to build full form or $payment->buildFormFields($orderData) to build form fields.

Examples:

Build full form:

Order data must have fields: amount, currency, orderId, customerFirstName, customerLastName

Optional data: customerEmail, urlSuccess, urlFailure, urlReturn, urlNotification, twistoData, version

Example $orderData:

$orderData = [
    'amount' => (int) (1.33 * 100), //INT, price should be multipled by 100 so for example 1.33 will be 133 
    'currency' => 'PLN', // see suported currences in 'Supported variables' sectiom
    'orderId' => '123456790',
    'customerFirstName' => 'John',
    'customerLastName' => 'Doe',
    'customerEmail' => 'john@doe.com',
    'urlSuccess' => 'https://example.com/success.php',
    'urlFailure' => 'https://example.com/failure.php',
    'urlReturn' => 'https://example.com/return.php',
];

use Payment\Payment;

public function yourFunction()
{
    // ...
    
    $payment = new Payment(\Payment\Util::ENVIRONMENT_PRODUCTION, 'b1c8bd6c7411455aab3295c48fcf26a7', 'e692d208484b4d5887755362d0587a00', 'pl');
    
    $form = $payment->buildOrderForm($orderData); // You can also pass second parameter `language` to generate form that will redirect to this language
}

The $form must contain $orderData and additional keys (signature must have which one hash method was use (for example sha256)), like:

serviceId, merchantId, signature

<input type="hidden" value="133" name="serviceId">
<input type="hidden" value="133" name="merchantId">
<input type="hidden" value="133" name="amount">
<input type="hidden" value="PLN" name="currency">
<input type="hidden" value="123456790" name="orderId">
<input type="hidden" value="John" name="customerFirstName">
<input type="hidden" value="Doe" name="customerLastName">
<input type="hidden" value="john@doe.com" name="customerEmail">
<input type="hidden" value="https://example.com/success.php" name="urlSuccess">
<input type="hidden" value="https://example.com/failure.php" name="urlFailure">
<input type="hidden" value="https://example.com/return.php" name="urlReturn">
<input type="hidden" value="7c46b5c9836520a9a0552d31136a705d3f7a7ea3db13de87f41fb3ee31f6dbff;sha256" name="signature">

and then you can wrap it to your own form HTML tag

<form method="POST" action="http://example.com/pl/payment">
    <input type="hidden" value="133" name="serviceId">
    <input type="hidden" value="133" name="merchantId">
    <input type="hidden" value="133" name="amount">
    <input type="hidden" value="PLN" name="currency">
    <input type="hidden" value="123456790" name="orderId">
    <input type="hidden" value="John" name="customerFirstName">
    <input type="hidden" value="Doe" name="customerLastName">
    <input type="hidden" value="john@doe.com" name="customerEmail">
    <input type="hidden" value="https://example.com/success.php" name="urlSuccess">
    <input type="hidden" value="https://example.com/failure.php" name="urlFailure">
    <input type="hidden" value="https://example.com/return.php" name="urlReturn">
    <input type="hidden" value="7c46b5c9836520a9a0552d31136a705d3f7a7ea3db13de87f41fb3ee31f6dbff;sha256" name="signature">
    
    <input class="button" type="submit" value="Continue" id="submit-payment-form">
