Installation

You can install the package via composer:

composer require climactic/laravel-credits

Publish and run the migrations:

php artisan vendor:publish --tag="credits-migrations"
php artisan migrate

Optionally publish the config file:

php artisan vendor:publish --tag="credits-config"

Configuration

return [
    // Allow negative balances
    'allow_negative_balance' => false,
    
    // Table name for credit transactions (change if you've updated the migration table name)
    'table_name' => 'credits',
];

Usage

Setup Your Model

Add the HasCredits trait to any model that should handle credits:

use Climactic\Credits\Traits\HasCredits;

class User extends Model
{
    use HasCredits;
}

Basic Usage

// Add credits
$user->addCredits(100.00, 'Subscription Activated');

// Deduct credits
$user->deductCredits(50.00, 'Purchase Made');

// Get current balance
$balance = $user->getCurrentBalance();

// Check if user has enough credits
if ($user->hasEnoughCredits(30.00)) {
    // Proceed with transaction
}

Transfers

Transfer credits between two models:

$sender->transferCredits($recipient, 100.00, 'Paying to user for their service');

Transaction History

// Get last 10 transactions
$history = $user->getTransactionHistory();

// Get last 20 transactions in ascending order
$history = $user->getTransactionHistory(20, 'asc');

Historical Balance

Get balance as of a specific date:

$date = new DateTime('2023-01-01');
$balanceAsOf = $user->getBalanceAsOf($date);

Metadata

Add additional information to transactions:

$metadata = [
    'order_id' => 123,
    'product' => 'Premium Subscription'
];

$user->addCredits(100.00, 'Purchase', $metadata);
