Currency Switcher for WooCommerce

• If you are experiencing some sort of issue regarding paypal, like incorrect currency code displayed in notification emails or anything else, please try to disable the default paypal component bundled with WooCommerce and use this plugin instead

If you are trying to display the converted price on a custom template for example you can use our alg_get_product_price_by_currency() function.
e.g

add_action('woocommerce_single_product_summary', function(){
    if ( ! class_exists( 'Alg_WC_Currency_Switcher' ) ) {
        return;
    }
    global $product;
    $price = get_post_meta( get_the_ID(), '_regular_price', true);
    $converted_price = alg_get_product_price_by_currency( $price, alg_get_current_currency_code(), $product, true );
    $converted_price_formatted = wc_price( $converted_price );
    echo "<h1>{$converted_price}</h1>";
    echo "<h1>{$converted_price_formatted}</h1>";
});

Please make sure you are using at least one Cryptocurrency on your Currency settings.
You can install All Currencies for WooCommerce plugin to enable them

If you are trying the National Bank of Georgia server option with no success, make sure that your server has the SoapClient library installed and enabled

If you want for example to turn on the rounding for all products except for Bitcoin, supposing you’ve enabled rounding and pretty price on plugin’s settings:

add_filter( 'alg_wc_currency_switcher_correction', function ( $correction, $currency ) {
    if ( $currency == 'BTC' ) {
        $correction['rounding'] = 'no_round';
        $correction['pretty_price'] = 'no';
    }

    return $correction;
}, 10, 2 );

If you want to set a currency just accessing an URL you can append the alg_currency variable with the currency code you want.
e.g

http://www.yoursite.com?alg_currency=USD
