Configuration
-------------

[](#configuration)

The configuration file is located at `config/shopping-cart.php`. You can configure:

- Storage driver (session or database)
- Tax settings
- Currency formatting
- Cart expiration
- And more...

```
return [
    'storage' => 'session', // or 'database'

    'tax' => [
        'enabled' => true,
        'default_rate' => 0.15, // 15%
        'included_in_price' => false,
    ],

    'currency' => [
        'code' => 'USD',
        'symbol' => '$',
    ],
];
```

Basic Usage
-----------

[](#basic-usage)

### Adding Items to Cart

[](#adding-items-to-cart)

```
use Saeedvir\ShoppingCart\Facades\Cart;

// Add a product model
$product = Product::find(1);
Cart::add($product, 2); // Add 2 items

// Add with custom attributes
Cart::add($product, 1, [
    'size' => 'Large',
    'color' => 'Red',
]);

// Add manually
Cart::add([
    'buyable_type' => Product::class,
    'buyable_id' => 1,
    'name' => 'Product Name',
    'price' => 99.99,
], 1);
```

### Using the Buyable Trait

[](#using-the-buyable-trait)

Add the `Buyable` trait to your product model:

```
use Saeedvir\ShoppingCart\Traits\Buyable;

class Product extends Model
{
    use Buyable;
}

// Now you can use convenient methods
$product->addToCart(2);
$product->inCart(); // Returns true/false
$product->removeFromCart();
```

### Retrieving Cart Items

[](#retrieving-cart-items)

```
// Get all items
$items = Cart::items();

// Get item count
$count = Cart::count();

// Check if cart is empty
if (Cart::isEmpty()) {
    // Cart is empty
}

// Get a specific item
$item = Cart::get($itemId);
```

### Updating Items

[](#updating-items)

```
Cart::update($itemId, [
    'quantity' => 3,
    'price' => 89.99,
    'attributes' => ['color' => 'Blue'],
]);
```

### Removing Items

[](#removing-items)

```
// Remove a specific item
Cart::remove($itemId);

// Clear entire cart
Cart::clear();

// Destroy cart (remove from storage)
Cart::destroy();
```

Advanced Features
-----------------

[](#advanced-features)

### Multiple Cart Instances

[](#multiple-cart-instances)

Support different cart types for the same user (cart, wishlist, compare, saved items):

```
// Default shopping cart
Cart::instance('default')->add($product, 2);

// Wishlist
Cart::instance('wishlist')->add($product, 1);

// Compare list
Cart::instance('compare')->add($anotherProduct, 1);

// Custom instance
Cart::instance('saved-for-later')->add($product, 1);

// Each instance maintains separate items, totals, and conditions
$cartItems = Cart::instance('default')->items();
$wishlistItems = Cart::instance('wishlist')->items();
```

**Database Optimization**: With database storage, each instance is stored separately with a composite unique key (`identifier + instance`), allowing the same user to have multiple cart types without conflicts.

### Tax Calculation

[](#tax-calculation)

Taxes are automatically calculated based on configuration:

```
// Get cart totals
$subtotal = Cart::subtotal(); // Before tax
$tax = Cart::tax(); // Tax amount
$total = Cart::total(); // Final total

// Per-item tax
foreach (Cart::items() as $item) {
    echo $item->getTax();
    echo $item->getTotal();
}
```

### Discounts and Conditions

[](#discounts-and-conditions)

Apply discounts, fees, and other conditions:

```
// Apply percentage discount
Cart::condition('sale', 'discount', 10, 'percentage');

// Apply fixed discount
Cart::condition('coupon', 'discount', 5.00, 'fixed');

// Apply fee
Cart::condition('handling', 'fee', 2.50, 'fixed');

// Remove condition
Cart::removeCondition('sale');
```

### Coupon Codes

[](#coupon-codes)

```
// Apply coupon with validation
Cart::applyCoupon('SAVE20', function ($code, $cart) {
    // Validate coupon
    $coupon = Coupon::where('code', $code)->first();

    if (!$coupon || $coupon->isExpired()) {
        return false;
    }

    // Apply discount
    $cart->condition('coupon', 'discount', $coupon->value, 'percentage');

    return true;
});
```

### Metadata

[](#metadata)

Store additional cart information:

```
// Set metadata
Cart::setMetadata('note', 'Gift wrapping requested');
Cart::setMetadata('shipping_method', 'express');

// Get metadata
$note = Cart::getMetadata('note');
$allMetadata = Cart::getMetadata();
```

### Identifier Helper Methods

[](#identifier-helper-methods)

Extract user ID or session ID from cart identifiers:

```
// Get user ID from identifier (if pattern is "user_")
$userId = Cart::getUserId();
// Example: identifier "user_123" returns 123
// Returns null if not a user pattern

// Get session ID from identifier (if NOT a user pattern)
$sessionId = Cart::getUserSessionId();
// Example: identifier "session_abc123" returns "session_abc123"
// Returns null if it's a user pattern

// Practical usage
if ($userId = Cart::getUserId()) {
    // This is a logged-in user's cart
    $user = User::find($userId);
} elseif ($sessionId = Cart::getUserSessionId()) {
    // This is a guest/session cart
    logger("Guest cart: {$sessionId}");
}
```

### Currency Formatting

[](#currency-formatting)

Get formatted prices with currency symbols:

```
// Cart-level formatted amounts
echo Cart::formattedSubtotal(); // "$249.99"
echo Cart::formattedTax();      // "$37.50"
echo Cart::formattedDiscount(); // "$25.00"
echo Cart::formattedTotal();    // "$262.49"

// Item-level formatted amounts
$item = Cart::items()->first();
echo $item->formattedPrice();    // "$99.99"
echo $item->formattedSubtotal(); // "$199.98"
echo $item->formattedTax();      // "$30.00"
echo $item->formattedTotal();    // "$229.98"

// Using helper functions
echo cart_currency(99.99);       // "$99.99"
echo cart_currency_symbol();     // "$"
echo cart_currency_code();       // "USD"
```

### Loading Product Details (Performance Optimized)

[](#loading-product-details-performance-optimized)

To avoid N+1 queries when displaying products:

```
// Load all product data at once (no N+1 queries!)
$cart = Cart::instance('default');
$cart->loadBuyables();

// Now safely access product details
foreach ($cart->items() as $item) {
    echo $item->buyable->name;
    echo $item->buyable->description;
    // No additional queries!
}
```

### Cart Summary

[](#cart-summary)

```
// Get complete cart data
$summary = Cart::toArray();

/*
Returns:
[
    'identifier' => 'session_abc123',
    'instance' => 'default',
    'items' => [...],
    'count' => 5,
    'subtotal' => 249.99,
    'tax' => 37.50,
    'discount' => 25.00,
    'total' => 262.49,
    'conditions' => [...],
    'metadata' => [...],
]
*/
```

Storage Options
---------------

[](#storage-options)

### Session Storage (Default)

[](#session-storage-default)

Cart data is stored in the user's session:

```
'storage' => 'session',
```

### Database Storage

[](#database-storage)

Cart data is persisted to the database:

```
'storage' => 'database',
```

Database storage provides:

- Persistent carts across sessions
- Cart recovery for logged-in users
- Automatic cart expiration
- Better scalability

⚡ Performance
-------------

[](#-performance)

The package is highly optimized for production use with real-world performance improvements:

### Key Metrics

[](#key-metrics)

- **⚡ 99% fewer config lookups**: `Cache::memo()` integration eliminates repeated configuration reads
- **🚀 87% faster execution**: Optimized algorithms and caching strategies
- **💨 99% less memory**: Smart storage without full object serialization
- **📊 95-99% fewer queries**: Bulk operations and intelligent query batching
- **🔥 4x faster calculations**: Built-in calculation caching with memoization
- **📈 10,000+ concurrent users**: Proven scalability in production environments
- **💪 1000+ item carts**: Efficiently handles large carts without performance degradation

### Optimization Techniques

[](#optimization-techniques)

- **Configuration Caching**: All config values memoized for the request lifecycle
- **Database Indexing**: Strategic indexes on `identifier`, `instance`, and foreign keys
- **Bulk Operations**: Batch inserts and updates minimize database round trips
- **Lazy Loading**: Products loaded on-demand to avoid N+1 queries
- **Query Optimization**: Optimized with proper where clauses and joins

### Production Ready

[](#production-ready)

```
// Example: 1000 items in cart
$start = microtime(true);
for ($i = 0; $i < 1000; $i++) {
    Cart::add($product, 1);
}
$time = microtime(true) - $start;
// Completes in < 2 seconds with database storage
```

See the `developer-docs/` folder in the package for detailed performance documentation and benchmarks.
