methods
Develop a Payment Plugin
All payment plugins will be located in group easyshoppayment. When the execute method is called, the $order and $payment properties have already been presented.
// Import and use EasyShop Payment Legacy
JLoader::import('easyshop.plugin.payment');
use ES\Plugin\Payment;
class PlgEasyshoppaymentMypayment extends Payment
{
// This method will be called when an order has created by customer
public function execute()
{
$orderAmount = $this->order->get('total_price');
$products = $this->order->get('products');
$testMode = $this->payment->params->get('test');
// ...
}
// This method will be called by a payment gateway (such as PayPal...)
public function callback()
{
}
}
Develop a Shipping Plugin
All shipping plugins will be located in group easyshopshipping.
// Import and use EasyShop Shipping Legacy
JLoader::import('easyshop.plugin.shipping');
use ES\Plugin\Shipping;
use Joomla\Registry\Registry;
class PlgEasyshopshippingMyshipping extends Shipping
{
// This method will consider to register one or many shipping elements
public function onEasyshopShippingRegister()
{
/**
* @var $cart \ES\Cart
* @var $method \ES\Method
*/
$cart = easyshop('class.cart');
$method = easyshop('class.method');
$subTotal = easyshop('state')->get('cart.subTotal'); // Get subTotal in cart
foreach ($method->getShippingMethods() as $shipping)
{
$params = new Registry($shipping->params);
$minAmount = (float) $params->get('min_order_amount');
// Check some restrictions
if($subTotal >= $minAmount)
{
$shipTotal = (float) $params->get('shipping_flat_fee');
$shippingMethod = $shipping;
$shippingMethod->total = $shipTotal;
$shippingMethod->params = $params;
// Now this shipping method will be displayed in the checkout page
$method->addShippingMethod($shippingMethod);
}
}
}
}
How to create params for Payment/Shipping method
Place your params fields in the manifest XML file inside easyshop/fields[@name="params"]/fieldset[@name]. This works for the both payment method and shipping method.
