# 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 ```php use RealRashid\Cart\Facades\Cart; Cart::add('id_1', 'Product 1', 2, 19.99, ['size' => 'L']); ``` ### Updating cart item quantity ```php Cart::update($rowId, 3); // Update quantity to 3 Cart::update($rowId, ['name' => 'New Product Name']); // Update other details ``` ### Associating a cart item with an Eloquent model ```php Cart::associate($rowId, 'App\Models\Product'); $item = Cart::get($rowId); echo $item->model->name; // Access associated product model ``` ### Showing cart contents and totals ```php $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.
