laravel-shoppingcart

A Shopping Cart Implementation for Laravel.

Based on johannesschobel laravel-shoppingcart

Installation

Install the package through Composer.

composer require mohammadalavi/laravel-shoppingcart

Then, you simply add the provided migration file using the following command:

php artisan vendor:publish --provider="MohammadAlavi\ShoppingCart\ShoppingCartServiceProvider" --tag="migrations"

and then you migrate your database using

php artisan db:migrate

If you want, you can overwrite the basic configuration of this package using the following command:

php artisan vendor:publish --provider="MohammadAlavi\ShoppingCart\ShoppingCartServiceProvider" --tag="config"

This will copy the shoppingcart configuration file to your config folder. Using this file, you can customize the various parameters of the package. Currently, not many are available, however, I will be adding more and more ;)

Usage

The ShoppingCart Facade provides some neat methods to deal with the shopping cart in general. These methods are:

LOAD a ShoppingCart from the database

ShoppingCart::load($identifier, $name = null);

Load the cart with the identifier and name from the database. If no name is provided, the default name default will be used. If no cart exists, an empty cart will be returned. This cart remains temporary as long as no items are stored.

CLEAR a ShoppingCart

ShoppingCart::clear();

Removes the current instance of the cart from the database.

ADD Items to the Cart

ShoppingCart::addItem(
   $id, 
   $name = null, 
   $type = null, 
   $qty = 1, 
   Money $price = null, 
   $uri = null, 
   array $options = []
);

This method allows for adding items to the cart. The basic usage allows you to directly specify the item you want to set. For example

ShoppingCart::addItem(
   '1234', 
   'Basic T-Shirt', 
   'products', 
   10, 
   new Money(999, new Currency('EUR')), // note the value is added in cents! 
   '/products/1234', 
   ['size' => 'large', 'color' => 'black']
);

would add 10 "Basic T-Shirts", each costs 9.99 EUR to the cart. The customer has specified a color and size.

You may, however, add the Buyable interface to your products in order to simplify this process. This will require you to implement additional methods on the model (you can add the CanBePurchased Trait in order to make a "best guess").

This would allow you to just add a specific product:

$product = Product::find(1234); // remember, Product must implement the Buyable interface!
ShoppingCart::addBuyable(
   $product, 
   10, 
   ['size' => 'large', 'color' => 'black']
);

would result in the same cart as above. However, the id, name, price and uri are directly taken from the model!

REMOVE Items from the Cart

ShoppingCart::removeItem($row)

To remove an item from the shopping cart you need to have its rowId. This rowId can be obtained, for example, via the ShoppingCart::load() or ShoppingCart::getContent() method.

$rowId = "30168b5f5a78bc48d08b4d5a125a9d90";
ShoppingCart::removeItem($rowId);

UPDATE Items in the Cart

ShoppingCart::updateItem($row, $qty = 1, array $options = [])

allows you to update a given row in the cart. This rowId can be obtained, for example, via the ShoppingCart::load() or ShoppingCart::getContent() method.

$rowId = "30168b5f5a78bc48d08b4d5a125a9d90";
ShoppingCart::updateItem($rowId, 1, ['color' => 'red']);

would update the quantity and options of the item (e.g., the product to be purchased shall be 'red' instead of 'black').

Items / Price / Taxes

The Cart also provides methods to

• get the amount of items in the cart => getItemCount()
• get the content of the cart. This returns all items in the cart => getContent()
• get the value of the current cart
  • get the taxes of the cart => getTaxes()
  • get total (value including taxes) => getTotal()
  • get subtotal (value without taxes) => getSubTotal()
• get the "associated" Buyable model => resolveModel()
