solagirl on "[Plugin: WooCommerce - excelling eCommerce] The currency symbol for China Yuan is incorrect"

The code I provided earlier was found a bug, it does not work when there are more than one product in the cart. So here is an updated version. It takes care the condition of multiple products and converts shipping cost.

add_filter('woocommerce_paypal_args', 'convert_rmb_to_usd');
function convert_rmb_to_usd($paypal_args){
    if ( $paypal_args['currency_code'] == 'RMB'){
        $convert_rate = 6.2116; //Set converting rate
        $count = 1;
        while( isset($paypal_args['amount_' . $count]) ){
            $paypal_args['amount_' . $count] = round( $paypal_args['amount_' . $count] / $convert_rate, 2);
            $count++;
        }
    }
    return $paypal_args;
}
