Extensions

Extension	Description
Swap	Addition to the laravel-wallet library for quick setting of exchange rates
uuid	Addition to laravel-wallet to support model uuid keys
Warm Up	Addition to the laravel-wallet library for refresh balance wallets

Usage

Add the HasWallet trait and Wallet interface to model.

use Bavix\Wallet\Traits\HasWallet;
use Bavix\Wallet\Interfaces\Wallet;

class User extends Model implements Wallet
{
    use HasWallet;
}

Now we make transactions.

$user = User::first();
$user->balanceInt; // 0

$user->deposit(10);
$user->balance; // 10
$user->balanceInt; // int(10)

$user->withdraw(1);
$user->balance; // 9

$user->forceWithdraw(200, ['description' => 'payment of taxes']);
$user->balance; // -191

Purchases

Add the CanPay trait and Customer interface to your User model.

use Bavix\Wallet\Traits\CanPay;
use Bavix\Wallet\Interfaces\Customer;

class User extends Model implements Customer
{
    use CanPay;
}

Add the HasWallet trait and interface to Item model.

Starting from version 9.x there are two product interfaces:

• For an unlimited number of products (ProductInterface);
• For a limited number of products (ProductLimitedInterface);

An example with an unlimited number of products:

use Bavix\Wallet\Traits\HasWallet;
use Bavix\Wallet\Interfaces\Customer;
use Bavix\Wallet\Interfaces\ProductInterface;

class Item extends Model implements ProductInterface
{
    use HasWallet;

    public function getAmountProduct(Customer $customer): int|string
    {
        return 100;
    }

    public function getMetaProduct(): ?array
    {
        return [
            'title' => $this->title, 
            'description' => 'Purchase of Product #' . $this->id,
        ];
    }
}

Example with a limited number of products:

use Bavix\Wallet\Traits\HasWallet;
use Bavix\Wallet\Interfaces\Customer;
use Bavix\Wallet\Interfaces\ProductLimitedInterface;

class Item extends Model implements ProductLimitedInterface
{
    use HasWallet;

    public function canBuy(Customer $customer, int $quantity = 1, bool $force = false): bool
    {
        /**
         * This is where you implement the constraint logic. 
         * 
         * If the service can be purchased once, then
         *  return !$customer->paid($this);
         */
        return true; 
    }
    
    public function getAmountProduct(Customer $customer): int|string
    {
        return 100;
    }

    public function getMetaProduct(): ?array
    {
        return [
            'title' => $this->title, 
            'description' => 'Purchase of Product #' . $this->id,
        ];
    }
}

I do not recommend using the limited interface when working with a shopping cart. If you are working with a shopping cart, then you should override the PurchaseServiceInterface interface. With it, you can check the availability of all products with one request, there will be no N-queries in the database.

Proceed to purchase.

$user = User::first();
$user->balance; // 100

$item = Item::first();
$user->pay($item); // If you do not have enough money, throw an exception
var_dump($user->balance); // 0

if ($user->safePay($item)) {
  // try to buy again
}

var_dump((bool)$user->paid($item)); // bool(true)

var_dump($user->refund($item)); // bool(true)
var_dump((bool)$user->paid($item)); // bool(false)

Eager Loading

// When working with one wallet
User::with('wallet');

// When using the multi-wallet functionality
User::with('wallets');

How to work with fractional numbers?

Add the HasWalletFloat trait and WalletFloat interface to model.

use Bavix\Wallet\Traits\HasWalletFloat;
use Bavix\Wallet\Interfaces\WalletFloat;
use Bavix\Wallet\Interfaces\Wallet;

class User extends Model implements Wallet, WalletFloat
{
    use HasWalletFloat;
}

Now we make transactions.

$user = User::first();
$user->balance; // 100
$user->balanceFloat; // 1.00

$user->depositFloat(1.37);
$user->balance; // 237
$user->balanceFloat; // 2.37
