In header on my store I need to display a symbol of current currency. In my custom block I inherited from \Magento\Directory\Block\Currency and added following code:

class Currency extends \Magento\Directory\Block\Currency
     * @return string
    public function getCurrentCurrencySymbol()
        return $this

This is work good for me, but when I added additional currency (Russian Ruble) in en_US locale function returned NULL.

I found temporary solution, but I not sure that this good idea.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$currencies = $objectManager

return $currencies[$this->getCurrentCurrencyCode()]['displaySymbol'];

Tell me, please, how I can solve the issue.

  • You should not use objectManager directly in files. You should use dependency injection as Magento 2 coding standards. – Prince Patel Jul 18 '17 at 16:19
  • Ok, thank you. Where I can read about this? – Evgeny Levinsky Jul 18 '17 at 17:11

Try below code. Hope you will get your answer

    $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$storeManager = $objectManager->get('Magento\Store\Model\StoreManagerInterfa‌​ce'); 
    $currencyCode = $storeManager->getStore()->getCurrentCurrencyCode(); 
    $currency = $objectManager->create('Magento\Directory\Model\CurrencyFact‌​ory')->create()->loa‌​d($currencyCode); 
    echo $currencySymbol = $currency->getCurrencySymbol();

    Yes, of course - it return null too. I added symbol tag in /vendor/magento/zendframework1/library/Zend/Locale/Data/en.xml file and it works, issue not happens. But it's right solution? – Evgeny Levinsky Jul 18 '17 at 16:01
  • But modifying the core library isn't good. In the further update it'll be lost – Ashwani Shukla Jul 26 '18 at 10:41
