Cart ​

Purpose ​

This package lets you manage user Shopping Cart, and defines what is a buyable Product (and what are Productables, that is sellable things), that can be then added to the Cart. This package also lets your users create Orders and buy content of their Carts.

Installation ​

• composer require escolalms/cart
• php artisan migrate
• php artisan db:seed --class="EscolaLms\Cart\Database\Seeders\CartPermissionSeeder"

Dependencies ​

This package depends on EscolaLms/Payments package for creating and processing Payments for Orders.

Usage ​

Product ​

EscolaLms\Cart\Models\Product is a Model that represents abstract buyable thing that can be added to Cart and bought. Product by itself has no additional functionality than being bought and assigned to Users.

Products consist of one (Single type products) or more (Bundle type products) Productables - that is, Models representing concrete things that are sold in your (LMS) application, for example Courses. Productables must implement Productable interface.

Productable ​

EscolaLms\Cart\Contracts\Productable interface defines how Model representing sellable things behave and which methods and relations they must contain.

Defining Productables ​

To create (and sell) Products, you need to define Productables. A Productable is a Model implementing EscolaLms\Cart\Models\Contracts interface (and possibly using EscolaLms\Cart\Contracts\ProductableTrait). After adding this interface to your Model, you need to call EscolaLms\Cart\Facades\Shop::registerProductableClass(Productable::class) in one of your Service Providers boot method. This will enable using this Productable Model as a (part of) Product which can then be sold.

Shop Facade ​

Shop Facade wraps EscolaLms\Cart\Services\ProductService giving access to methods related to registering Productables and managing Products.

Cart Model ​

EscolaLms\Cart\Models\Cart is a model representing User Cart. Every User can have one active (existing) Cart at given time.

To create Cart (or retrieve current active Cart) for a given user, you need to call EscolaLms\Cart\Services\ShopService::cartForUser($user) method.

Cart Manager ​

Cart and its content is managed using EscolaLms\Cart\Services\CartManager class instance attached to that Cart, instead of manipulating Cart object directly. CartManager is used by EscolaLms\Cart\Services\ShopService (and you probably don't need to use it directly, as methods in ShopService represent all sensible use cases).

Shop Service ​

Shop Service contains functionality related to managing Cart content (adding/removing Products), and purchasing Cart (storing Cart data as an Order and processing payment flow).

Endpoints ​

All the endpoints are defined in .

Tests ​

Run ./vendor/bin/phpunit to run tests. See tests directory as it's a quite good starting point for understanding how this package works. Especially pay attention to tests/Mocks directory, as it represents core concepts of Productable and use of Productable Trait & Interface.
