There are two buttons which switch between these two currencies. When KRW is selected price format: 10,000W and when USD is selected the price format is: 100$. User requirements are to display $100 when USD is selected instead of 100$. User has the following code in function.php

add_filter('woocommerce_price_format','change_currency_pos');

function change_currency_pos( $currency_pos, $currency ) {
     switch( $currency ) {
          case 'USD': $currency_pos = '%1$s%2$s'; break;
          case 'KRW': $currency_pos = '%2$s%1$s'; break;

        }
        return $currency_pos;
        }

   add_filter('woocommerce_price_format','change_currency_pos');

None of the above code works, how to resolve this issue?

Answer

Let’s assume that it adds a $_GET variable named currency to the end of URL, but the idea is that you set a value for the woocommerce_currency_pos option based on some data provided by the currency controller plugin.

add_filter( 'pre_option_woocommerce_currency_pos', 'change_currency_position' );
function change_currency_position(){
    if( ! isset( $_GET['currency'] ) {
        return false;
    }

    if ( 'USD' == $_GET['currency'] ){
        return 'left';
    } elseif ( 'KRW' == $_GET['currency'] ){
        return 'right';
    } 
}

Again, let’s assume that 'right' is the default position. You only need is the option in case of USD currency. In which case you would need this:

add_filter( 'pre_option_woocommerce_currency_pos', 'change_currency_position' );
function change_currency_position(){
    if( isset( $_GET['currency'] && 'USD' == $_GET['currency'] ){
        return 'left';
    } 
}
