About:

Simple shopping-cart implementation package for Laravel

For Laravel 5.7 you don't need to add service provider & alias:
Add service provider to 'providers' array in config/app.php
Icemix\LaravelShoppingCart\CartServiceProvider::class,
Add alias to 'aliases' array in config/app.php
'Cart' => Icemix\LaravelShoppingCart\Facades\Cart::class,

Now you can do migrating, to create 'shoppingcart' table:

You can do custom changes in 'config/cart.php' file.
Note: Don't forget to be sure that in config/app.php 'product_model' have right model namespace.

Usage

The shoppingcart gives you the following methods to use:

Cart::add()

Adding an item to the cart is really simple, you just use the add() method, which accepts a variety of parameters.

In its most basic form you can specify the id, name, quantity, price of the product you'd like to add to the cart.

As an optional fifth parameter you can pass it options, so you can add multiple items with the same id, but with (for instance) a different size.

The add() method will return an CartItem instance of the item you just added to the cart.

Maybe you prefer to add the item using an array? As long as the array contains the required keys, you can pass it to the method. The options key is optional.

New in version 2 of the package is the possibility to work with the Buyable interface. The way this works is that you have a model implement the Buyable interface, which will make you implement a few methods so the package knows how to get the id, name and price from your model. This way you can just pass the add() method a model and the quantity and it will automatically add it to the cart.

As an added bonus it will automatically associate the model with the CartItem

As an optional third parameter you can add options.

Finally, you can also add multipe items to the cart at once. You can just pass the add() method an array of arrays, or an array of Buyables and they will be added to the cart.

When adding multiple items to the cart, the add() method will return an array of CartItems.

Cart::update()

To update an item in the cart, you'll first need the rowId of the item. Next you can use the update() method to update it.

If you simply want to update the quantity, you'll pass the update method the rowId and the new quantity:

If you want to update more attributes of the item, you can either pass the update method an array or a Buyable as the second parameter. This way you can update all information of the item with the given rowId.

Cart::remove()

To remove an item for the cart, you'll again need the rowId. This rowId you simply pass to the remove() method and it will remove the item from the cart.

Cart::get()

If you want to get an item from the cart using its rowId, you can simply call the get() method on the cart and pass it the rowId.

Cart::content()

Of course you also want to get the carts content. This is where you'll use the content method. This method will return a Collection of CartItems which you can iterate over and show the content to your customers.

This method will return the content of the current cart instance, if you want the content of another instance, simply chain the calls.

Cart::destroy()

If you want to completely remove the content of a cart, you can call the destroy method on the cart. This will remove all CartItems from the cart for the current cart instance.

Cart::total()

The total() method can be used to get the calculated total of all items in the cart, given there price and quantity.

The method will automatically format the result, which you can tweak using the three optional parameters

You can set the default number format in the config file.

If you're not using the Facade, but use dependency injection in your (for instance) Controller, you can also simply get the total property $cart->total

Cart::tax()

The tax() method can be used to get the calculated amount of tax for all items in the cart, given there price and quantity.

The method will automatically format the result, which you can tweak using the three optional parameters

You can set the default number format in the config file.

If you're not using the Facade, but use dependency injection in your (for instance) Controller, you can also simply get the tax property $cart->tax

Cart::subtotal()

The subtotal() method can be used to get the total of all items in the cart, minus the total amount of tax.

The method will automatically format the result, which you can tweak using the three optional parameters

You can set the default number format in the config file.

If you're not using the Facade, but use dependency injection in your (for instance) Controller, you can also simply get the subtotal property $cart->subtotal

Cart::count()

If you want to know how many items there are in your cart, you can use the count() method. This method will return the total number of items in the cart. So if you've added 2 books and 1 shirt, it will return 3 items.

Cart::search()

To find an item in the cart, you can use the search() method.

This method was changed on version 2

Behind the scenes, the method simply uses the filter method of the Laravel Collection class. This means you must pass it a Closure in which you'll specify you search terms.

If you for instance want to find all items with an id of 1:

As you can see the Closure will receive two parameters. The first is the CartItem to perform the check against. The second parameter is the rowId of this CartItem.

The method will return a Collection containing all CartItems that where found

This way of searching gives you total control over the search process and gives you the ability to create very precise and specific searches.

Collections

On multiple instances the Cart will return to you a Collection. This is just a simple Laravel Collection, so all methods you can call on a Laravel Collection are also available on the result.

As an example, you can quicky get the number of unique products in a cart:

Or you can group the content by the id of the products:

Instances

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

You can set the current instance of the cart by calling Cart::instance('newInstance'). From this moment, the active instance of the cart will be newInstance, so when you add, remove or get the content of the cart, you're 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 default, so when you're not using instances,Cart::content(); is the same as Cart::instance('default')->content().

Models

Because it can be very convenient to be able to directly access a model from a CartItem is it possible to associate a model with the items in the cart. Let's say you have a Product model in your application. With the 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 CartItem!

The model can be accessed via the model property on the CartItem.

If your model implements the Buyable interface and you used your model to add the item to the cart, it will associate automatically.

Here is an example:

Database

• Storing the cart
• Restoring the cart

Storing the cart

To store your cart instance into the database, you have to call the store($identifier) method. Where $identifier is a random key, for instance the id or username of the user.

Cart::store('username');

// To store a cart instance named 'wishlist'
Cart::instance('wishlist')->store('username');

Restoring the cart

If you want to retrieve the cart from the database and restore it, all you have to do is call the restore($identifier) where $identifier is the key you specified for the store method.

Cart::restore('username');

// To restore a cart instance named 'wishlist'
Cart::instance('wishlist')->restore('username');

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.
