PHP 7.0+
Laravel 5.5+

You can install the package using composer

If you are using Laravel < 5.5, you need to add provider to your config/app.php providers array:

Moecasts\Laravel\Wallet\WalletServiceProvider,

Publish the mirgrations file:

php artisan vendor:publish --tag=wallet-migrations

As optional if you want to modify the default configuration, you can publish the configuration file:

php artisan vendor:publish --tag=wallet-config

And create tables:

php artisan migrate

Finally, add feature trait into User model:

use Moecasts\Laravel\Wallet\Traits\HasWallets;

class User extends Model
{
    use HasWallets;
}

Configurations

Currencies

Here you can set supported currencies and its coefficient.

return [
    'currencies' => [
        'POI',
        'COI',
        'CNY'
    ],
    'coefficient' => [
        'COI' => 100.,
        'POI' => 1
    ],
    'exchange' => [
        'COI' => [
            'POI' => 100,
            'CNY' => 1
        ],
        'CNY' => [
            'COI' => 1
        ]
    ],
];

Wallet

Here you can add default wallet.

return [
    'wallet' => [
        'table' => 'wallets',
        'model' => \Moecasts\Laravel\Wallet\Models\Wallet::class,
        'default' => [
            'currency' => 'POI'
        ],
    ],
];

Usage

Get Wallet

This function will return the wallet of the currency if the currency is supported.

$wallet = $user->getWallet($currency)

$wallet->balance

// return the user transfers of all his wallets
$user->transfers
// return the wallet transfers
$wallet->transfers

// return the user transactions of all his wallets
$user->transactions
// return the wallet transactions
$wallet->transactions

Deposit

$wallet->deposit($amount, $meta = [], $confirmed = true)

$wallet->deposit(233)
$wallet->deposit(233, ['description' => 'Deposit Testing'])

Withdraw

$wallet->withdraw($amount, $meta = [], $confirmed = true)

$wallet->withdraw(233)
$wallet->withdraw(233, ['description' => 'withdraw Testing'])

// forceWithdraw though balance is not enough
$wallet->forceWithdraw(233)

Exchage

Add the exchange configurations to your config/wallet.php.

return [
    'exchange' => [
        // To be exchanged cuurency
        'COI' => [
            // target currency => (one to be exchanged cuurency = ? target currency)
            'POI' => 100,
            'CNY' => 1
        ],
    ]
];

Add the Exchangeable interface to User model.

use Illuminate\Database\Eloquent\Model;
use Moecasts\Laravel\Wallet\Interfaces\Exchangeable;
use Moecasts\Laravel\Wallet\Traits\HasWallets;

class User extends Model implements Exchangeable
{
    use HasWallets;
}

Then you can do this:

$wallet = $userWallet->getWallet('COI')

// $wallet->exchange(string $currency, float $mouant)
$wallet->exchange('POI', 10)
// This will return null but not exception when it failed.
$wallet->safeExchange('POI', 10)
// This will exchange though balance is not enough
$wallet->forceExchange('POI', 10)

Transfer

Add the Transferable interface to User model.

use Moecasts\Laravel\Wallet\Interfaces\Transferable;
use Moecasts\Laravel\Wallet\Traits\HasWallets;

class User extends Model implements Transferable
{
    use HasWallets;
}

Then you can do this:

$user = User::find(1);
$transferable = User::find(2);

$wallet = $user->getWallet($currency);

// $wallet->transfer(Transferable $transferable,float $amount,?array $meta = [], string $action = 'transfer'))
$wallet->transfer($transferable, 233);

// This will return null but not exception when it failed.
$wallet->safeTransfer($transferable, 233);

Wallet with the same currency of the Transferable will receive the payment.

Pay

Add the HasWallets trait and Product interface to Item model.

use Moecasts\Laravel\Wallet\Interfaces\Product;

class Item extends Model implements Product
{
    use HasWallets;

    public function canBePaid(string $action = 'paid'): bool
    {
        return true;
    }

    public function getProductAmount(string $action = 'paid'): float
    {
        switch ($action) {
            case 'paid':
                return 10;
                break;

            default:
                return 23.3;
                break;
        }
    }

    public function getProductMeta(string $action = 'PAID'): ?array
    {
        return [
            'title' => 'Paid for #' . $this->id
        ];
    }

    public function getReceiptWallet(string $currency): Wallet
    {
        return $this->getWallet($currency);
    }
}

If you want to pay to the author, you can do this.

As optional you can remove HasWallets trait.

use Illuminate\Database\Eloquent\Relations\BelongsTo;
use Moecasts\Laravel\Wallet\Interfaces\Product;

class Item extends Model implements Product
{
    public function author(): BelongsTo
    {
        return $this->belongsTo(User::class, 'user_id');
    }

    public function canBePaid(string $action = 'paid'): bool
    {
        return true;
    }

    public function getProductAmount(string $action = 'paid'): float
    {
        switch ($action) {
            case 'paid':
                return 10;
                break;

            default:
                return 23.3;
                break;
        }
    }

    public function getProductMeta(string $action = 'paid'): ?array
    {
        return [
            'title' => 'Paid for #' . $this->id
        ];
    }

    public function getReceiptWallet(string $currency): Wallet
    {
        return $this->author->getWallet($currency);
    }
}

Then you can do this.

$user = User::first();
$product = Item::first();

$wallet = $user->getWallet($currency);

// $wallet->pay(Product $item, string $action = 'paid', bool $force = false)
$wallet->pay($item)
$wallet->pay($item, 'read')

// This will return null but not exception when it failed.
$wallet->safePay($item, 'paid')

// return bool
$wallet->paid($item, $action = 'paid')

Refund

Add the Refundable interface to Item model.

use Moecasts\Laravel\Wallet\Interfaces\Product;
use Moecasts\Laravel\Wallet\Interfaces\Refundable;

class Item extends Model implements Product, Refundable
{
    use HasWallets;

    public function canBePaid(string $action = 'paid'): bool
    {
        return true;
    }

    public function getProductAmount(string $action = 'paid'): float
    {
        switch ($action) {
            case 'paid':
                return 10;
                break;

            default:
                return 23.3;
                break;
        }
    }

    public function getProductMeta(string $action = 'PAID'): ?array
    {
        return [
            'title' => 'Paid for #' . $this->id
        ];
    }

    public function getReceiptWallet(string $currency): Wallet
    {
        return $this->getWallet($currency);
    }
}
