How to change currency position according to currency in WordPress

The user has an online store which has two options for currencies i.e. KRW and USD. 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;
}
    function change_currency_pos() {
        $currency_pos = get_option('woocommerece_currency');

        switch($currency_pos) {
            case 'USD': $format = '%1$s%2$s'; break;
            case 'KRW': $format = '%2$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';
    } 
}
