README

This package provides your application with the functionality to use currencies and easily retrieve conversion rates and apply them to prices.

It makes use of external API's, some of which require an API key. You'll find more details in the instructions below.

Installation

Run the following command in your project directory to install the package:

composer require ez-laravel/currencies

Publish the migrations and seeds using the following command:

php artisan vendor:publish --provider="EZ\Currencies\Providers\CurrenciesServiceProvider" --tag=database

Run the migrations with:

php artisan migrate

Update your DatabaseSeeder.php class to load the new seeder and afterwards run the following commands to seed your database:

composer dumpautoload
php artisan db:seed

Run the following command to (optionally) publish the package's config file:

php artisan vendor:publish --provider="EZ\Currencies\Providers\CurrenciesServiceProvider" --tag=config

Configuration

Default currency

The default currency is set to EUR, which you can change by adding the following key to your .env file with the desired currency code:

CURRENCIES_DEFAULT=USD

Currency Conversion Rate API

The following APIs are supported or under development to be supported:

• Fixer.io
• Ratesapi.io
• Frankfurter.app
• Exchangeratesapi.io

You can change the drive the package will use by adding the following key to your .env file:

CURRENCIES_API_DRIVER=fixer

Fixer

fixer

Get an API key from the fixer.io website and add it to your .env file:

CURRENCIES_FIXER_API_KEY=xxxxxxxx

RatesAPI

rates

The ratesapi.io website does not require an API key!

Frankfurter

frankfurter

The frankfurter.app website does not require an API key!

ExchangeRatesAPI

exchangerates

The exchangeratesapi.io website does not require an API key!

Usage

Available methods

// Currency getters
$currencies = Currencies::getAll();
$currency = Currencies::find($id);
$currency = Currencies::findBy($field, $value);
$currency = Currencies::findByCode($code);
$num_currencies = Currencies::countAll();

// Preloaded currency getters
$currencies = Currencies::getAllPreloaded();
$currency = Currencies::findPreloaded($id);
$currency = Currencies::findPreloadedBy($field, $value);

// Currency conversion rate getters
$conversionRates = Currencies::getConversionRates();
$conversionRates = Currencies::getConversionRatesByCode($code);

// Update all currency conversion rates
Currencies::updateConversionRates();

// Conversion methods
$convertedValue = Currencies::convert($fromCurrency, $toCurrency, $x);
$convertedValues = Currencies::convertToAll($fromCurrency, $x);

Updating conversion rates

When you've just installed the package you should perform the following command to manually update all of your currencies conversion rates:

php artisan currencies:update-conversion-rates

To keep the conversion rates up-to-date automatically schedule the above command to be ran every day (or at whatever interval you'd like) by updating your app/Console/Kernel.php file to include the following:

protected function schedule(Schedule $schedule)
{
    ...
    $schedule->command('currencies:update-conversion-rates')->daily();
}

More information on task scheduling can be found here.

Extending the Currency model

In most applications you will want to create relationships between the Currency model and for example a Product model or Order model. To do this simply create your own Currency model which extends the EZ\Currencies\Models\Currency model and update the model path in the currencies.php config file.

So for example:

<?php

namespace App\Models;

use EZ\Currencies\Models\Currency as BaseCurrency;

class Currency extends BaseCurrency
{
    public function products()
    {
        return $this->hasMany(Product::class);
    }
}

And in currencies.php

...
    'model' => App\Models\Currency::class,
...
