php - Calculations displaying 2 Currencies in WooCommerce Cart prices -

rp 500000 (usd $ 37.49) 

i want show 2 currency looks above in cart totals in woocommerce (subtotal, shipping, discount, insurance[custom fee], packing fee[custom fee]).

i succed make on subtotal, shipping, discount adding below filter.

but doesn't work on 2 custom fee (insurance, packing fee). when add $price_us .woocommerce-price-amount.amount class, insurance/packing fee amount going wrong. if did not add $price_us .woocommerce-price-amount.amount class ok, 1 currency.

function my_custom_price_format( $formatted_price, $price, $decimals,    $decimal_separator, $thousand_separator ) {   $price_us_int = intval(preg_replace('/[^0-9]+/', '', $price), 10);   $price_us_int = convert_idr_to_usd_cart($price_us_int);    $price_us = "usd $ $price_us_int";    return '<span class="woocommerce-price-amount amount">' . $formatted_price .' ( '.$price_us.' )</span>'; } add_filter( 'formatted_woocommerce_price', 'my_custom_price_format', 20, 5 ); 

is there me situation.

update

there 2 main problems:

1) using wrong hook. instead should use wc_price.

2) in code , it's because should directly use unformatted $price argument available without using this:

$price_us_int = intval(preg_replace('/[^0-9]+/', '', $price), 10); 

now don't have code of custom function convert_idr_to_usd_cart() don't how make calculation , how set number of decimals or converted custom price.

so have use for testing purpose:

// testing function convert_idr_to_usd_cart( $price ){     $convertion_rate = 0.016;     $new_price = $price * $convertion_rate;     return number_format($new_price, 2, '.', ''); } 

here correct functional code (without issues):

add_filter( 'wc_price', 'my_custom_price_format', 10, 3 ); function my_custom_price_format( $formatted_price, $price, $args ) {      // currency conversion custom calculation function     $price_usd = convert_idr_to_usd_cart($price);      // currency symbol dollars     $currency = 'usd';     $currency_symbol = get_woocommerce_currency_symbol( $currency );     $price_usd = $currency_symbol.$price_usd; // adding currency symbol      // usd formatted price     $formatted_price_usd = "<span class='price-usd'> (usd $price_usd)</span>";      // return both formatted currencies     return $formatted_price . $formatted_price_usd; } 

code goes in function.php file of active child theme (or theme) or in plugin file.

this code tested , works.
