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($rowId, 3); // Update quantity to 3
Cart::update($rowId, ['name' => 'New Product Name']); // Update other details

Associating a cart item with an Eloquent model

Cart::associate($rowId, 'App\Models\Product');
$item = Cart::get($rowId);
echo $item->model->name; // Access associated product model

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.
