Retrieving price for shipping method on checkout

[deanfields]

I'm using this for retriving and displaying the price for the shipping method at checkout:

method.priceForOrder(cart)|commerceCurrency(cart.paymentCurrency) - but the price being returned isn't the price for the particular currency set. I can't see a way to pull this out?

I am also having this issue. Is there any update on displaying the correct shipping method price for the particular currency?

We also came across this issue ourselves on the craft 4 branch, plugin version 3.0.0-beta.4

We've put a fix in place by adding a new twig extension into the core plugin files. For anyone else who is interested, you can make the following change to twigextensions/CurrencyPricesTwigExtension.php

Alter getFilters function by adding the following into the array returned:

new TwigFilter('currencyShippingPrice', [$this, 'currencyShippingPrice']),

Add an entirely new function lower down:

public function currencyShippingPrice($cart, $shippingId, $currency, $format = true, $stripZeros = false): null|string
	{
		$this->_validatePaymentCurrency($currency);

		$shipping = CurrencyPrices::$plugin->shipping->getPricesByShippingRuleIdAndCurrency($shippingId, $currency);
		if (!$shipping) {
			return null;
		}

		$total = $shipping['baseRate'];

		$percentageRate = $shipping['percentageRate'];
		$perItemRate = $shipping['perItemRate'];
		$weightRate = $shipping['weightRate'];

		/** @var $cart Order */
		foreach ($cart->getLineItems() as $cartItem) {
			$percentageAmount = $cartItem->getSubtotal() * $percentageRate;
			$perItemAmount = $cartItem->qty * $perItemRate;
			$weightAmount = ($cartItem->weight * $cartItem->qty) * $weightRate;
			$total += Currency::round($percentageAmount + $perItemAmount + $weightAmount);
		}

		if ($shipping['minRate'] != 0 && $total < Currency::round($shipping['minRate'])) {
			$total = Currency::round($shipping['minRate']);
		}

		if ($shipping['maxRate'] != 0 && $total > Currency::round($shipping['maxRate'])) {
			$total = Currency::round($shipping['maxRate']);
		}

		if ($format) {
			$total = Craft::$app->getFormatter()->asCurrency($total, $currency, [], [], $stripZeros);
		}

		return $total;
	}

Once the above changes are done, all you need to do in your templates is the following:

{{ cart|currencyShippingPrice(shippingRule.id, cart.paymentCurrency) }}

This allows a preview of the shipping price for each method without needing to be selected and fully calculated.

It would be nice to see this plugin leave beta and potentially have the above fix included. Thanks all.
