Custom Discount Types

If you have registered your own discount types in the core, you will likely want to provide an interface so authenticated staff members can add the data required.

You need to make sure you have registered your discount with the Lunar core beforehand.

use Lunar\Hub\Facades\DiscountTypes;
use App\Http\Livewire\Components\CustomDiscountComponent;
use App\DiscountTypes\MyCustomDiscountType;

DiscountTypes::register(MyCustomDiscountType::class, CustomDiscountComponent::class);

The component UI should then appear when the user has chosen the custom discount type. Create a Livewire component to handle your custom discount type.

<?php

namespace App\Http\Livewire\Components;

use Lunar\Hub\Http\Livewire\Components\Discounts\Types\AbstractDiscountType;
