I used below event

<event name="currency_display_options_forming">
 <observer name="vendor_extension_change_currency_position" instance="VendorModuleObserverChangeCurrencySymbol" />
</event>

then,

<?php 
namespace VendorModuleObserver; 
use MagentoFrameworkEventObserverInterface; 
use MagentoFrameworkLocaleCurrency; 
use MagentoDirectoryModelCurrencyFactory;
class ChangeCurrencySymbol implements ObserverInterface

 private $logger;
 protected $symbolFactory;
 protected $_coreSession;
 private $currencyCode;
 public function __construct(
 PsrLogLoggerInterface $logger,
 MagentoCurrencySymbolModelSystemCurrencysymbolFactory $symbolFactory,
 MagentoFrameworkSessionSessionManagerInterface $coreSession,
 CurrencyFactory $currencyFactory
 )
 $this->logger = $logger;
 $this->symbolFactory = $symbolFactory;
 $this->_coreSession = $coreSession;
 $this->currencyCode = $currencyFactory->create();
 

 public function execute(MagentoFrameworkEventObserver $observer)
 

 $baseCode = $observer->getEvent()->getBaseCode();
 $currencyOptions = $observer->getEvent()->getCurrencyOptions();
 $currencyOptions->addData($this->getCurrencyOptions($baseCode));
 return $this;
 

 protected function getCurrencyOptions($baseCode)
 
 $currencyCode = $this->getActiveCurrencyCode();

 $currencyOptions = [];
 if ($baseCode) 

 //$customCurrencySymbol = $this->symbolFactory->create()->getCurrencySymbol($baseCode);
 $currency = $this->currencyCode->load($currencyCode);
 $currencySymbol = $currency->getCurrencySymbol();
 $this->logger->info('currencySymbolObs'.$currencySymbol);

 $this->logger->info('customCurrencySymbol'.$customCurrencySymbol);
 if ($customCurrencySymbol) 
 $currencyOptions[Currency::CURRENCY_OPTION_SYMBOL] = $customCurrencySymbol;
 $currencyOptions[Currency::CURRENCY_OPTION_DISPLAY] = MagentoFrameworkCurrency::USE_SYMBOL;
 
 
 return $currencyOptions;
 

 public function getActiveCurrencyCode() 
 $this->_coreSession->start();
 $sessionCurrency = $this->_coreSession->getActiveCurrency();
 if(isset($sessionCurrency) && $sessionCurrency != '')
 return $sessionCurrency;
 else
 $sessionCurrency = GBP;
 return $sessionCurrency;
 

 

I have drop down in header with countries, Once any country is selected, I am setting value(Currency Code) in session by calling custom controller.

$currencyCode = $this->getRequest()->getPostValue('currency_code');
$this->_coreSession->setActiveCurrency($currencyCode);

I am looking for code how can we show custom currency symbol in all the pages.

I need to get the currency Symbol from currency code and show that symbol everywhere where prices are displayed. getActiveCurrencyCode() function returns the currency code.

Above code is not working as expected, This is hitting page continuously and site is getting hanged.

Can anyone help me to achieve this functionality.

Is this approach is good to achieve that functionality? Please look into it and share your thoughts with better approach. Thanks!!

You need add "symbol" in $currencyOptions array. Please add this below code in your observer file :

<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace VendorModuleObserver;

use MagentoFrameworkLocaleCurrency;
use MagentoFrameworkEventObserverInterface;

class CurrencyDisplayOptions implements ObserverInterface

 /**
 * @var MagentoCurrencySymbolModelSystemCurrencysymbolFactory
 */
 protected $symbolFactory;

 /**
 * @param MagentoCurrencySymbolModelSystemCurrencysymbolFactory $symbolFactory
 */
 public function __construct(MagentoCurrencySymbolModelSystemCurrencysymbolFactory $symbolFactory)
 
 $this->symbolFactory = $symbolFactory;
 

 /**
 * Generate options for currency displaying with custom currency symbol
 *
 * @param MagentoFrameworkEventObserver $observer
 * @return $this
 */
 public function execute(MagentoFrameworkEventObserver $observer)
 
 $baseCode = $observer->getEvent()->getBaseCode();
 $currencyOptions = $observer->getEvent()->getCurrencyOptions();
 $currencyOptions->addData($this->getCurrencyOptions($baseCode));

 return $this;
 

 /**
 * Get currency display options
 *
 * @param string $baseCode
 * @return array
 */
 protected function getCurrencyOptions($baseCode)
 
 $currencyOptions = [];
 if ($baseCode) 
 $customCurrencySymbol = $this->symbolFactory->create()->getCurrencySymbol($baseCode);
 if ($customCurrencySymbol) 
 $currencyOptions[Currency::CURRENCY_OPTION_SYMBOL] = $customCurrencySymbol;
 $currencyOptions[Currency::CURRENCY_OPTION_DISPLAY] = MagentoFrameworkCurrency::USE_SYMBOL;
 
 

 return $currencyOptions;
 

UPDATED :

You loaded every time currency object using this below line and create object in construct. You should remove this below lines :

$this->currencyCode = $currencyFactory->create(); // Remove this class from construct
$currency = $this->currencyCode->load($currencyCode);
$currencySymbol = $currency->getCurrencySymbol();

and use this below line for get currency symbol :

$customCurrencySymbol = $this->symbolFactory->create()->getCurrencySymbol($baseCode);

Remove generated folder and clean cache.

Hope, It will helpful for you.
