Cart Manager (Laravel 5.5 to Laravel 10.x)

Let's make the cart management with Laravel a breeze.

Just another shopping cart package?

There are a few well maintained shopping cart packages available but I wanted to have a solution which feels like the Laravel way and is more coupled with the database and provides additional functionality like shipping charges, discount, tax, total, round off, guest carts, etc. out-of-box while staying a very easy to use package.

Why/when to use?

Let us decide when this package should be used:

1. You are looking for an easy to use solution which provides cart feature for users as well as guests.
2. You want to make sure that the carting can work via APIs as well to support mobile applications.
3. You want features like Shipping charges, tax, discount, round off, etc.
4. You want to store cart data in Database, session or at a custom place.
5. You like using the packages which are more like the Laravel way

Configuration Options

cart_manager.php file contains the following config options for the package:

2. auth_guard : (default: web) The authentication guard that should be used to identify the logged in customer. This package can store carts for guest users as well as logged in users.

3. shipping_charges : (default: 10) The amount that should be applied as shipping of the order.

4. shipping_charges_threshold : (default: 100) The minimum order amount to avoid the shipping charges. Take a note that order amount is calculated as subtotal of the cart items - discount amount.

5. tax_percentage : (default: 6%) Tax is applied on subtotal of the cart items - discount amount + shipping charges and rounded to 2 decimals.

6. round_off_to : (default: 0.05) You may wish to round of the order amount to the nearest decimal point. Options are (0 or 0.05 or 0.1 or 0.5 or 1)

9. LC_MONETARY : (default: en_US.UTF-8) This option is used to display the various totals of the cart with a currency symbol. We use php's native money_format() function to display currency with amount.

Drivers

You can set the driver that should be used to store and retrieve cart details in the cart_manager.php config file. You can use existing ones or create your own driver.

Database Driver

Database driver stores the cart data in 2 tables: carts and cart_items. You can also remove stale data by running ClearCartDataCommand.

Using this driver allows you to store cart data on server and customer can be displayed the same cart across channels i.e. Mobile app, website, etc.

Session Driver

This driver stores the cart data in the session according to the session driver. This driver does not support cart management for guests via API as we cannot have a uniform way to track the user.

Updates in Item Prices

As this package stores the details of the cart items in a separate table or session, the cart data will not be updated if you update, price, name or image of the cart items.

If you update any of the item details regularly, we suggest you to run the following code before the final checkout to make sure that order totals are up-to-date as per the latest prices.

This code will go through each cart item and update to fresh details.

Using With API

Note: This feature is for Database driver only.

This package uses the cookies and sessions to maintain cart data during page reloads. As the APIs are stateless, we cannot use them to do the same.

To solve the issue, you can manually set the authenticated user id to maintain the cart data.

Running this code will tell the package to assign the cart data to the specified user.

Note: Guests cannot manage their carts via API as we cannot have a uniform way to track the user.

Events

Working with Laravel, how can we forget events?

This package fires various cart related events which you can listen to for any application updates.

1. CartCreated -> Fired when cart is created for the session for the first time and contains the full cart data in the variable $cartData.

2. CartItemAdded -> Fired when an item is added to the cart and contains the new item Eloquent model object in the variable $entity.

3. CartItemRemoved -> Fired when an item is removed from the cart and contains the new item Eloquent model object in the variable $entity.

4. DiscountApplied -> Fired when discount if applied to the cart and contains the full cart data in the variable $cartData.

5. CartCleared -> Fired when the cart is cleared.

Sample Usage

Add the event and listener entry in the EventServiceProvider class

Create respective listener:

Commands

Schedule the ClearCartDataCommand for the same.
