Get delivery method in if-statement

Hi there,

I try to get an extra fee on cart page depending on the delivery method and the subtotal.

If subtotal is bigger 100 and delivery is flat rate -> 6,00€
If subtotal is bigger 100 and delivery is international_delivery -> 12,00€
If none of those = 0

Now I’ve tried it with this code:

function add_fee() {
    global $woocommerce;
    $subtotal = (int)$woocommerce->cart->subtotal;
    $versand = WC()->session->get( 'chosen_shipping_methods' );
    if($subtotal > '100' ) {
        if($versand = 'international_delivery') {
            $fee_value = 6;
        }
        else {
            $fee_value = 12;
        }
        $woocommerce->cart->add_fee( 'weiteres Paket (Pauschale)', $fee_value, $taxable = false,'');
}}
add_action( 'woocommerce_cart_calculate_fees', 'add_fee' );

If the subtotal is less 100 it shows nothing. If it is about 100 it shows the 6,00€ fee. But if I change the delivery method to international it shows also 6,00€.

I think that there is a problem getting the delivery method.

A var_dump($versand) shows

array(1) { [0]=> string(22) "international_delivery" }

Any ideas to get the delivery_method n a good way?

Thanks and regards

Thorsten
