Download the PHP package kingpabel/shoppingcart without Composer

LaravelShoppingcart

A simple shoppingcart implementation for Laravel 4.

Installation

Install the package through Composer. Edit your project's composer.json file by adding:

From Laravel 4.2 to Laravel 5.2

Next, run the Composer update command from the Terminal:

composer update

Now all you have to do is add the service provider of the package and alias the package. To do this open your app/config/app.php file.

Add a new line to the service providers array:

'Kingpabel\Shoppingcart\ShoppingcartServiceProvider'

And finally add a new line to the aliases array:

'Cart'            => 'Kingpabel\Shoppingcart\Facades\Cart',

Now you're ready to start using the shoppingcart in your application.

Overview

Look at one of the following topics to learn more about LaravelShoppingcart

• Usage
• Collections
• Instances
• Models
• Exceptions
• Events
• Example

Usage

The shoppingcart gives you the following methods to use:

Cart::add()

Cart::update()

Cart::remove()

Cart::get()

Cart::content()

Cart::destroy()

Cart::total()

Cart::subtotal()

Cart::discount()

Cart::setCustomDiscount(5.00)

Cart::customDiscount()

Cart::count()

Cart::search()

Collections

As you might have seen, the Cart::content() and Cart::get() methods both return a Collection, a CartCollection and a CartRowCollection.

These Collections extends the 'native' Laravel 4 Collection class, so all methods you know from this class can also be used on your shopping cart. With some addition to easily work with your carts content.

Instances

Now the packages also supports multiple instances of the cart. The way this works is like this:

You can set the current instance of the cart with Cart::instance('newInstance'), at that moment, the active instance of the cart is newInstance, so when you add, remove or get the content of the cart, you work with the newInstance instance of the cart. If you want to switch instances, you just call Cart::instance('otherInstance') again, and you're working with the otherInstance again.

So a little example:

N.B. Keep in mind that the cart stays in the last set instance for as long as you don't set a different one during script execution.

N.B.2 The default cart instance is called main, so when you're not using instances,Cart::content(); is the same as Cart::instance('main')->content().

Models

A new feature is associating a model with the items in the cart. Let's say you have a Product model in your application. With the new associate() method, you can tell the cart that an item in the cart, is associated to the Product model.

That way you can access your model right from the CartRowCollection!

Here is an example:

The key to access the model is the same as the model name you associated (lowercase). The associate() method has a second optional parameter for specifying the model namespace.

Exceptions

The Cart package will throw exceptions if something goes wrong. This way it's easier to debug your code using the Cart package or to handle the error based on the type of exceptions. The Cart packages can throw the following exceptions:

Events

The cart also has events build in. There are five events available for you to listen for.

Example

Below is a little example of how to list the cart content in a table:
