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;
}`
