Entities

Payment entity

In addition to traditional id and createdAt fields, Payment entity has eleven important properties:

uuid is a string representing a unique identifier of the payment entity
createdAt represent the creation date
payedAt represent the date when the payment has been made
expirationDate represent the date when the payment expires
status indicate in which status the payment currently is
cancellationReason is a string representing the reason of the cancellation of the payment
requiredPrice is a float representing the price required
capturedPrice is a float representing the price captured
authorizedPayment is an int that represent the list of the payment authorised (used like binary flags)
selectedPayment is an integer representing the payment method that has been chosen
contexts is an ArrayCollection of all the contexts for the entity
callbackUrl is an array of callbacks url that will be used is some events in the application (when the payment is saved for example). Here are the possible value and purpose of the callback url:
- succeeded : the url that will be called when an payment authorization successes
- failed : the url that will be called when an payment authorization failed
- cancelled : the url that will be called when an payment is cancelled

Context entity

In addition to traditional id field, Context entity has three important properties:

key is a string representing the key of the context
value is a string representing the value attach to this context
payment is a Payment entity representing the Payment related to this context

Validators

You have the possibility to validate a Payment entity with PaymentValidator class:

<?php

use Fei\Service\Payment\Validator\PaymentValidator;
use Fei\Service\Payment\Entity\Payment;

$paymentValidator = new PaymentValidator('create');
$payment = new Payment();

//validate returns true if your Payment instance is valid, or false in the other case
$isPaymentValid = $paymentValidator->validate($payment);

//getErrors() allows you to get an array of errors if there are some, or an empty array in the other case
$errors = $paymentValidator->getErrors();

By default, only uuid, createdAt, expirationDate, status, requiredPrice, authorizedPayment and callbackUrl properties must not be empty, but you're also able to validate only a few properties of your entity, using validate methods:

<?php

use Fei\Service\Payment\Validator\PaymentValidator;
use Fei\Service\Payment\Entity\Payment;

$paymentValidator = new PaymentValidator('create');

$payment = new Payment();
$payment->setUuid('uuid');

$paymentValidator->validateUuid($payment->getUuid());

// will return an empty array : all of our definitions are correct
$errors = $paymentValidator->getErrors();
echo empty($errors); // true

// callbackUel can not be empty, let's try to set it as an empty string
$payment->setCallbackUrl([]);
$paymentValidator->validateCallbackUrl($payment->getCallbackUrl());

// this time you'll get a non-empty array
$errors = $paymentValidator->getErrors();

echo empty($errors); // false
print_r($errors);

/**
* print_r will return:
*
*    Array
*    (
*        ['callbackUrl'] => Array
*            (
*                'The callback URL cannot be empty'
*            )
*    )
**/
