fractalmask on "[Plugin: WooCommerce Custom Currencies] Paypal Payment error: Currencies do not match"

I need something like :

if  $order->get_order_currency() is-not-equals-to $posted['mc_currency']

  then check

        if the $posted['amt'] value returned by paypal is-equals-to ( value of product x conversion rate )

           tell woocommerce order that this is ok to have $order->update_status is everything fine
