Fetching Currency Symbols in Magento 2
To retrieve the currency symbol in Magento 2, utilize the PriceCurrencyInterface's getCurrencySymbol() method. This approach allows you to obtain the symbol for the default store currency or specify a particular store by its ID or code.
Method Syntax:
/**
* @param null|string|bool|int|\Magento\Framework\App\ScopeInterface $scope
* @param \Magento\Framework\Model\AbstractModel|string|null $currency
* @return string
*/
public function getCurrencySymbol($scope = null, $currency = null);
Implementation Steps:
Create a Block or Model Class:
Begin by creating a class that will use the PriceCurrencyInterface to fetch the currency symbol.
<?php
namespace YourNamespace\Currency\Model;
use Magento\Framework\Pricing\PriceCurrencyInterface;
class CurrencySymbol
{
private PriceCurrencyInterface $priceCurrency;
public function __construct(PriceCurrencyInterface $priceCurrency)
{
$this->priceCurrency = $priceCurrency;
}
public function getCurrencySymbol($scope = null, $currencyCode = null): string
{
$currency = $this->priceCurrency->getCurrency($scope, $currencyCode);
return $currency ? $currency->getCurrencySymbol() : '';
}
}
Usage Examples:
You can call the getCurrencySymbol() method with different parameters to fetch the desired currency symbol:
// Instantiate the CurrencySymbol class
$currencySymbolModel = new \YourNamespace\Currency\Model\CurrencySymbol($priceCurrency);
// Get the default store currency symbol
echo $currencySymbolModel->getCurrencySymbol();
// Get the currency symbol by store ID
echo $currencySymbolModel->getCurrencySymbol(1);
// Get the currency symbol by store code
echo $currencySymbolModel->getCurrencySymbol('default');
Parameter Details:
- $scope: Accepts null, store ID, or store code. If null, it defaults to the current store.
- $currency: Accepts null or a currency code string. If null, it uses the store's base currency.
Additional Methods:
Alternatively, you can retrieve the current currency symbol using the LocaleCurrency class:
use Magento\Framework\Locale\CurrencyInterface;
class CurrencySymbol
{
private $localeCurrency;
public function __construct(CurrencyInterface $localeCurrency)
{
$this->localeCurrency = $localeCurrency;
}
public function getCurrentCurrencySymbol()
{
$currencyCode = $this->localeCurrency->getCurrency()->getCurrencyCode();
return $this->localeCurrency->getCurrency($currencyCode)->getSymbol();
}
}
In this method, getCurrency() retrieves the currency object for the current locale, and getSymbol() fetches its symbol.
