Cart Development
When to use this skill
Use this skill when implementing shopping cart features, e-commerce workflows, or wishlist management in Laravel applications using the realrashid/cart package.
Features
- Publish configuration (
vendor:publish tag: cart-config).
- Manage multiple cart instances (e.g., 'main', 'wishlist').
- Add, update, and remove items with custom options and associated models.
- Automatically calculate subtotals, taxes, and totals based on cart contents.
Examples
Adding an item to the cart
use RealRashid\Cart\Facades\Cart;
Cart::add('id_1', 'Product 1', 2, 19.99, ['size' => 'L']);
Updating cart item quantity
Cart::update($rowId, 3);
Cart::update($rowId, ['name' => 'New Product Name']);
Associating a cart item with an Eloquent model
Cart::associate($rowId, 'App\Models\Product');
$item = Cart::get($rowId);
echo $item->model->name;
Showing cart contents and totals
$cartItems = Cart::content();
$total = Cart::total();
$tax = Cart::tax();
Implementation tips for AI agents
- Use
Cart::instance('wishlist') for multiple cart purposes within the same session.
- Leverage model association to avoid manual database lookups when displaying cart items.
- Suggest
php artisan vendor:publish --tag=cart-config to customize default tax rates and storage settings.
