Required plugins: none. Tested with the latest stable OctoberCMS build 349.

Installation

• install plugin VojtaSvoboda.CnbRates from your Backend -> Settings -> System -> Updates -> Install plugins
• select which services you want to use at Settings -> System -> Misc -> ČNB Rates

Events

The best and easiest way how to use this plugin is by events.

This plugin provide two events. When you set Scheduled updates correctly (see below), this events will be fired each day automatically and always comes with fresh rates data.

• vojtasvoboda.cnbrates.exchange.updated Fired when exchange rates are updated
• vojtasvoboda.cnbrates.pribor.updated Fired when PRIBOR rates are updated

Using event in your Plugin.php:

public function boot()
{
    // ČNB rates update listener
    Event::listen('vojtasvoboda.cnbrates.exchange.updated', function($rates)
    {
        // update my plugin with fresh data
        $this->updateMyProducts($rates);
    });
}

All methods are fired after calling update method e.g. updateTodayExchangeRates() manually or by scheduler.

Scheduled updates

For scheduled updates to operate correctly, you should add the following Cron entry to your server. Editing the crontab is commonly performed with the command crontab -e.

* * * * * php /path/to/artisan schedule:run >> /dev/null 2>&1

Be sure to replace /path/to/artisan with the absolute path to the artisan file in the root directory of October.

Thats all, rates will be updated every day and related events will be fired.

Exchange rates service

$cnb = App::make('cnb');
// rates for today
$rates = $cnb->getExchangeRate();
