Laravel Wallet

Appearance

Transfer ​

Transfer in our system are two well-known Deposit and Withdraw operations that are performed in one transaction.

The transfer takes place between wallets.

User Model ​

It is necessary to expand the model that will have the wallet. This is done in two stages:

  • Add Wallet interface;
  • Add the HasWallet trait;

Let's get started.

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

class User extends Model implements Wallet
{
    use HasWallet;
}

The model is prepared to work with a wallet.

Example contract ​

php
$transfer = $user1->transfer(
    $user2,
    511,
    new Extra(
        deposit: [
            'type' => 'extra-deposit',
        ],
        withdraw: new Option(
            [
                'type' => 'extra-withdraw',
            ],
            false // confirmed
        ),
        extra: [
            'msg' => 'hello world',
        ],
    )
);

Make a Transfer ​

Find user:

php
$first = User::first(); 
$last = User::orderBy('id', 'desc')->first(); // last user
$first->getKey() !== $last->getKey(); // true

As the user uses HasWallet, he will have balance property. Check the user's balance.

php
$first->balance; // 100
$last->balance; // 0

The transfer will be from the first user to the second.

php
$first->transfer($last, 5); 
$first->balance; // 95
$last->balance; // 5

It's simple!

Force Transfer ​

Check the user's balance.

php
$first->balance; // 100
$last->balance; // 0

The transfer will be from the first user to the second.

php
$first->forceTransfer($last, 500); 
$first->balance; // -400
$last->balance; // 500

It's simple!
