Hi there... i am wondering if you can help me?
i am tying to set different shipping classes to different shipping methods... here is what is what i found so far but dont quite get it:

`add_filter('woocommerce_package_rates', 'manage_method_basedon_shipping_class', 10, 2);
function manage_method_basedon_shipping_class($methods, $package)
{
// $package have cart items, so loop through that and get your shipping classes available in the cart. like $item->get_shipping_class().

// So you have all the classes now. Now based on this unset shipping methods from $method function. $method have all available shipping methods

// now return $methods;

}
`

By adding && wc_clean( $_GET['_shop_order_payment_method'] )!="" you can still search within all orders, including orders that do not have a payment method.

` /**
* Process bulk filter order payment method
*
* @SInCE 1.0.0
*
* @param array $vars query vars without filtering
* @return array $vars query vars with (maybe) filtering
*/
public function filter_orders_by_payment_method_query( $vars ) {
global $typenow;

	if ( 'shop_order' === $typenow && isset( $_GET['_shop_order_payment_method'] ) && wc_clean( $_GET['_shop_order_payment_method'] )!="" ) {

		$vars['meta_key']   = '_payment_method';
		$vars['meta_value'] = wc_clean( $_GET['_shop_order_payment_method'] );
	}

	return $vars;
}`

Can we make it filter the active payment methods only ?, because there are the default payment methods which we don't use and they are deactivated in woocommerce settings, but still appear in the filter dropdown despite we don't have any orders with that default payments methods like the check or pay on delivery.

Yes, you can, change line 72 to:
$gateways = WC()->payment_gateways->get_available_payment_gateways();
