🛒 Laravel Extendable Basket
Laravel Extendable Basket provides several abstract classes that implement basic ecommerce basket functionality. These classes must be extended by your application.
Installation
Just install the latest version using composer.
Setup
You need to perform various setup steps in order to make use of this package.
Database tables
Two database tables are required to store basket and basket item data. By default these are called baskets
and basket_items
. This package provides database migrations to create these tables.
To run these migrations, enter the following artisan command.
Models
Now you need to create two related models, one to hold basket details and one to hold basket items details. Two example models are shown below. They can be modified or added to as necessary.
Create a Basket model.
Create a BasketItem model.
Basketable interface
Anything that can be placed in the basket provided by this library is considered
'basketable'. You can make any existing Eloquent model basketable simply by
making it implement the Basketable
interface.
For example, if you had a Product
model, you can change it as follows.
Note that any basketable models must have a getPrice()
and a getName()
method
that returns a numeric price and textual name of the basketable, respectively.
Usage
This section describes the use of the basket and basket item functionality provided by this package. It assumes you have performed the required installation and setup, in the manner specified above.
Remember to use
the basket and/or basket item models you have created, where
necessary.
Getting the current basket
From anywhere in your application, you can get the current basket. If no basket currently exists in the session, one will be created.
Getting a new basket
If you need to discard the current basket and create a new one, such as after a
user has placed an order, you can use the getNew
method.
This method essentially doubles as emptying the basket.
Manual basket management
The static methods getCurrent
and getNew
store the current basket ID in the
session. If you do not want this, you can manage baskets yourself, as you would
with any Eloquent model.
Add item(s) to the basket
After getting the current basket, you can easily add items to it using the basket's
add
method. You need to provide it with a quantity and any basketable model.
Optionally, you can also provide an array of basket item meta data, which could be used to store information about variations on a product.
Getting basket items
Getting items from the basket and the basketable model they contain can be easily done. See the example below.
Changing the quantity of a basket item
Each basket item has a quantity associated with it. It is set when an item is
added to the basket, but can be modified later via the setQuantity
method.
Removing a basket item
Basket items can easily be removed simply by deleting them. See the following example.
Getting the unit cost of a basket item
Getting the unit cost of a basket item just involves calling the getPrice
method of
the basketable model associated with the basket item. See the example below.
Getting the line total of a basket item
The basket item class provides a getPrice
method that gets the line total. This is simply
the basketable's price multiplied by the basket item quantity. The example code below
shows how to use this method.
Getting the total number of items in the basket
There is a single method in the basket class that can sum up all the basket item quantities.
Just call the getTotalNumberOfItems
method, as follows.
Getting the basket subtotal
A getSubtotal
method is provided in the basket class that provides the total of all
items in the basket. See the following example.
If you wish to add delivery costs or discounts, you can create a new getTotal
method
in your basket class. This method can call the getSubtotal
method, and then modify
and return it, in whatever way you wish.
An example Basket class implementing this idea is shown below.
