Payments

If you’re looking for a guide on how to create your own Payment Driver, or for a more in-depth look at how they work, head over to the extending section.

Overview

Lunar takes a driver based approach with Payments, meaning you are free to use either add ons to support the provider you wish to use, or you can create your own to meet your exact needs.

Configuration

All configuration for payments is located in config/lunar/payments.php. Here you can specify different types of payments and the driver each one should use.

<?php

return [
    'default' => env('PAYMENTS_TYPE', 'offline'),

    'types' => [
        'cash-in-hand' => [
            'driver' => 'offline',
            'released' => 'payment-offline',
        ],
        'card' => [
            'driver' => 'stripe',
            'released' => 'payment-received',
        ],
    ],
];

Usage

To use a payment driver, you need to pass the type of payment you wish to use, this will then return an instance of the driver.

$driver = \Lunar\Facades\Payments::driver('card');

We can then set the cart.

$driver->cart(\Lunar\Models\Cart $cart);

Set any additional data that the driver may need.

$driver->withData([
    'payment_token' => $token,
]);

Finally, we can authorize the payment.

$driver->authorize();

As you’d expect, orders on an online system show what users have purchased. They are linked to a Cart and you can only have 1 order per cart in the database.

Create an order

You can either create an order directly, or the recommended way is via a Cart model.

$order = \Lunar\Models\Order::create([/** .. */]);

// Recommended way
$order = Cart::first()->createOrder();

If you are using the CartSession you can create a order via the facade, this will then handle removing the cart from the session if you want it to.

$order = CartSession::createOrder();

By default, this will create the order and remove the cart id from the session. You can, however retain the cart id if you want by passing an option boolean parameter to the method:

$order = CartSession::createOrder(false);

Now when you create the order, you will still have the cart id in the session. So what’s happening when we call createOrder on a cart, that’s so different from just creating an order manually? Well there’s a few steps Lunar takes to make sure data stays consistent and valid, it also means that a lot of the columns on an order will automatically be populated based on the cart. Here’s the order things happen when you call createOrder:

We check if the Cart has been calculated and it’s totals are populated, if not we calculate
Validation happens on the cart to ensure we have all the data we need for the order, things like billing info etc.
Creation is about to happen, so before that we get any modifiers that have been set up and pass through the Cart so you can make any changes beforehand.
We create the order from the Cart including CartLine models and copying CartAddress models across to the new order.
We associate the newly created order to the Cart
The new order is then run through a series of post creation modifiers so you can make any adjustments to the new order.

Given that there is validation taking place and there could be exceptions thrown, it makes sense to wrap this function in a try/catch.

try {
    $order = $cart->createOrder();
} catch (\Lunar\Exceptions\CartException $e) {
    // Return back to checkout.
}

If you want more fine grained control of what you do under the different exceptions, here they are:

\Lunar\Exceptions\Carts\BillingAddressIncompleteException;
\Lunar\Exceptions\Carts\BillingAddressMissingException;
\Lunar\Exceptions\Carts\OrderExistsException;

They each extend CartException so it depends on how much control you need. If you also want to check before you attempt this if the cart is ready to create an order, you can call the helper method:

$cart->canCreateOrder();

This essentially does the same as above, except we already catch the exceptions for you and just return false if any are caught.

Modifying Orders

If you need to programmatically change the Order values or add in new behaviour, you will want to extend the Order system. You can find out more in the Extending Lunar section for Order Modifiers.

Order Lines

Lunar\Models\OrderLine

Field	Description
id
order_id
purchasable_type	Class reference for the purchasable item e.g. `Lunar\Models\ProductVariant`
purchasable_id
type	Whether `digital`,`physical` etc
description	A description of the line item
option	If this was a variant, the option info is here
identifier	Something to identify the purchasable item, usually an `sku`
unit_price	The unit price of the line
unit_quantity	The line unit quantity, usually this is 1
quantity	The amount of this item purchased
sub_total	The sub total minus any discounts, excl. tax
discount_total	Any discount amount excl. tax
tax_breakdown	A json field for the tax breakdown e.g. `[{"name": "VAT", "total": 123, "percentage": 20}]`
tax_total	The total amount of tax applied
total	The grand total with tax
notes	Any additional order notes
meta	Any additional meta info you wish to store
created_at
updated_at

Create an order line

If you are using the createOrder method on a cart, this is all handled for you automatically.

\Lunar\Models\OrderLine::create([
    // ...
]);

Or via the relationship

$order->lines()->create([
    // ...
]);

Order Addresses

An order can have many addresses, typically you would just have one for billing and one for shipping.

If you are using the createOrder method on a cart, this is all handled for you automatically.

\Lunar\Models\OrderAddress::create([
    'order_id' => 1,
    'country_id' => 1,
    'title' => null,
    'first_name' => 'Jacob',
    'last_name' => null,
    'company_name' => null,
    'line_one' => '123 Foo Street',
    'line_two' => null,
    'line_three' => null,
    'city' => 'London',
    'state' => null,
    'postcode' => 'NW1 1WN',
    'delivery_instructions' => null,
    'contact_email' => null,
    'contact_phone' => null,
    'type' => 'shipping', // billing/shipping
    'shipping_option' => null, // A unique code for you to identify shipping
]);

// Or via the relationship.
$order->addresses()->create([
    // ...
]);

You can then use some relationship helpers to fetch the address you need:

$order->shippingAddress;
$order->billingAddress;

Shipping Options

A Shipping Tables addon is planned to make setting up shipping in the admin hub easy for most scenarios.

To add Shipping Options you will need to extend Lunar to add in your own logic. Then in your checkout, or where ever you want, you can fetch these options:

\Lunar\Facades\ShippingManifest::getOptions(\Lunar\Models\Cart $cart);

This will return a collection of Lunar\DataTypes\ShippingOption objects.

Adding the shipping option to the cart

Once the user has selected the shipping option they want, you will need to add this to the cart so it can calculate the new totals.

$cart->setShippingOption(\Lunar\DataTypes\ShippingOption $option);

Transactions

Lunar\Models\Transaction

Field	Description
id
success	Whether the transaction was successful
refund	`true` if this was a refund
driver	The payment driver used e.g. `stripe`
amount	An integer amount
reference	The reference returned from the payment Provider. Used to identify the transaction with them.
status	A string representation of the status, unlinked to Lunar e.g. `settled`
notes	Any relevant notes for the transaction
cart_type	e.g. `visa`
last_four	Last 4 digits of the card
meta	Any additional meta info you wish to store
created_at
updated_at

Create a transaction

Just because an order has a transaction does not mean it has been placed. Lunar determines whether an order is considered placed when the placed_at column has a datetime, regardless if any transactions exist or not.

Most stores will likely want to store a transaction against the order, this helps determining how much has been paid, how it was paid and give a clue on the best way to issue a refund if needed.

\Lunar\Models\Transaction::create([
    //...
]);

// Or via the order
$order->transactions()->create([
    //..
]);

These can then be returned via the relationship.

$order->transactions; // Get all transactions.

$order->charges; // Get all transactions that are charges.

$order->refunds; // Get all transactions that are refunds.

Payment Checks

Some providers return information based on checks that can occur before payment is validated and completed. This is usually related to 3DSecure but in some cases can relate to credit checks or anything the payment provider has deemed relevant to the transaction. You can get access to these checks via the paymentChecks() method on the Transaction.

foreach($transaction->paymentChecks() as $check) {
    $check->successful;
    $check->label;
    $check->message;
}

We will be looking to add support for the most popular payment providers, so keep an eye out here as we will list them all out. In the meantime, you can absolutely still get a storefront working, at the end of the day Lunar doesn’t really mind if you what payment provider you use or plan to use. In terms of an order, all it’s worried about is whether or not the placed_at column is populated on the orders table, the rest is completely up to you how you want to handle that. We have some helper utilities to make such things easier for you as laid out above. And as always, if you have any questions you can reach out on our Discord! —>
