PayPal Plugin for Cakephp 4.x

Installation and Usage

Install the Plugin

composer require jbennecker/cakephp-paypal

Load the Plugin

$ bin/cake plugin load PayPal

Run Plugin Migrations

$ bin/cake migrations migrate -p PayPal

Add a file called app_paypal.php to your config folder and enter the following info

<?php

return [
    'PayPal' => [
        'currency' => 'EUR',
    ],
];

The Plugin expects that you have a table called orders and the corresponding entity and table classes. The Order Entity class must implement the PayPal OrderInterface

use PayPal\Model\Entity\OrderInterface;

class Order extends Entity implements OrderInterface
{}

And OrdersTable must implement \PayPal\Model\TableOrdersTableInterface

use PayPal\Model\TableOrdersTableInterface;

class OrdersTable extends Table implements OrdersTableInterface
{}

After you have saved an order you can redirect the user to PayPal using this:

return $this->redirect([
    'plugin' => 'PayPal',
    'controller' => 'Paypals',
    'action' => 'pay',
    $order->id,
]);

This will redirect your customer to PayPal. After the customer has successfully paid, he will be redirected to

Router::url(['controller' => 'Orders', 'action' => 'confirm'], true);

PayPal will send an IPN to the Plugin. If the IPN successfully validated, the Plugin calls an Callbackmethod on your OrdersTable class.

PayPal will send an IPN to the Plugin. If the IPN was successfully validated, the Plugin calls the afterPayment-Callback on your Table-Class.

This Plugin uses PayPal Payments Standard

See PayPal sandbox testing guide for using Sandbox testing accounts.

public function afterPayment(Order $order): void
{
    // Further process the order
}
