## About
I created this package to be able to use it in my Laravel shop application.
I have seen the packages of others folks, but I either did not found every tools I need, or the tools were untested.
I hope to provide folks with a tested library so you can use it with confidence.
This package respects the [Semantic versioning](https://semver.org/).
## Requirements
- Composer
- PHP version 7.1+ (corresponds to Laravel 5.6+)
## Installation
In the root of your folder project, run this command:
```bash
composer require khalyomede/systempay:0.*
```
## Examples
- [1. Generating form payment hidden fields](#1-generating-form-payment-hidden-fields)
- [2. Processing a payment notification (IPN)](#2-processing-a-payment-notification-ipn)
### 1. Generating form payment hidden fields
In this example, we will only fill mandatories fields before generating the hidden HTML inputs to inject in an HTML page.
```php
setKey("foo")
->setSiteId("12345678")
->setTotalAmount(199.99)
->setContextMode(ContextMode::TEST)
->setCurrency(Currency::EUR)
->setPaymentConfiguration(PaymentConfiguration::SINGLE) // One shot payment
->setTransactionDate(new DateTime("NOW"))
->setTransactionId("xrT15p")
->setHashAlgorithm(HashAlgorithm::SHA256);
$fields = $payment->getHtmlFormFields();
$url = $payment->getFormUrl();
?>
= $fields ?>
Payer
```
### 2. Processing a payment notification (IPN)
In this example, we will provide with the raw POST response from the Systempay server to proces the notification.
```php
use Khalyomede\Systempay\PaymentNotification;
use Khalyomede\Systempay\TransactionStatus;
$notification = new PaymentNotification($_POST);
$notification->setKey("the-private-key");
if ($notification->hasValidSignature() && $notification->getTransactionStatus() === TransactionStatus::AUTHORISED) {
echo "all went good";
} else {
echo "depending the transaction status, you should perform a custom action";
}
```
