Apply discounts to your Eloquent Models on Laravel

Laravel Discounts

This package is inspired by Laravel Vouchers by Marcel Pociot.

Apply discounts to your Eloquent Models on Laravel, It can be used when we need to associate discounts with a certain amount to an eloquent model.

Any model

<?php

use Zaratedev\Discounts\Traits\Discountable;

class Item extends Model
{
    use Discountable;
}

...

$item = Item::find(1);
$item->createDiscount(100);

Requirements

The Laravel Discounts package requires PHP >= 7.2 and Laravel >= 5.8.

Installation

You can install the package via composer:

composer require zaratedev/laravel-discounts

The package will automatically register itself.

Migrations

You can publish the migrations

php artisan vendor:publish --provider="Zaratedev\Discounts\DiscountsServiceProvider" --tag="migrations"

Execute the command

php artisan migrate

Usage

The basic concept of this package is to create discounts, associated with a specific model. For example, you have a subscription application where the first three months must apply a discount to the subscription price.

Add the Zaratedev\Discounts\Traits\Discountable trait to your eloquent model that you want to use with discounts.

El trait Zaratedev\Discounts\Traits\Discountable can redeem discounts in the database.

Creating discounts

Using the facade

You can create one or many discounts using Discounts facade:

$subscription = Subscription::find(1);

$discounts = Discounts::create($subscription, 3, 100);

Using the Eloquent model

$subscription = Subscription::find(1);

// Returns an array of Discounts
$discounts = $subscription->createDiscounts(3, 100);

// Return a Discount model

$discount = $subscription->createDiscount(100);

Discounts with expiry dates

You can create discounts with expiration date.

$subscription = Subscription::find(1);

$subscription->createDiscounts(3, 100, today()->addMonths(4))

Redeeming Discounts

You can redeem the discount when it has been used.

$discount->redeem();

After redeeming a discount, this package initializes two observable events redeeming, redeemed so you can implement the events and listeners according to the bussines logic of your application.

Discount expired

If a discount tries to redeem an expired discount, the package will throw the following exception: Zaratedev\Discounts\Exceptions\DiscountExpired.
