I have an issue with Woocommerce. I would like to hide certain shipping methods based on the choice of payment method.
I want all 3 payment methods ("bacs", "cod" and "przelewy24") to be always visible. Based on the choice of the payment method, there should be only 2 shipping methods shown:
If payment method = "bacs" or "przelewy24", then I want only those 2 shipping methods to be shown:
flexible_shipping_single:25 flexible_shipping_single:26
If payment method = "cod", then I want only those 2 shipping methods to be shown:
flexible_shipping_single:23 flexible_shipping_single:24
I know that I can easily hide payment methods based on the shipping method, but I need it to be the other way around.
Do you guys know how can it be solved? :)
I was trying to figure it out using this thread: Disable shipping method based on chosen payment method in Woocommerce
But I failed :(
add_action( 'woocommerce_package_rates','show_hide_shipping_methods', 10, 2 );
function show_hide_shipping_methods( $rates, $package ) {
    // HERE Define your targeted shipping method ID
   
    $chosen_payment_method = WC()->session->get('chosen_payment_method');
    if( $payment_method == 'cod' ){ //if cod, hide unnecessary shipping methods
        unset($rates['flexible_shipping_single:25']);
        unset($rates['flexible_shipping_single:26']);
    }
    elseif ( $payment_method == 'przelewy24' ) //if przelewy24, hide unnecessary shipping methods
    {
        unset($rates['flexible_shipping_single:23']);
        unset($rates['flexible_shipping_single:24']);
    }
    elseif ( $payment_method == 'bacs' ) //if bacs, hide unnecessary shipping methods
    {
        unset($rates['flexible_shipping_single:23']);
        unset($rates['flexible_shipping_single:24']);
    }
    return $rates;
}
add_action( 'woocommerce_review_order_before_payment', 'payment_methods_trigger_update_checkout' );
function payment_methods_trigger_update_checkout(){
    // jQuery code
    ?>
    <script type="text/javascript">
        (function($){
            $( 'form.checkout' ).on( 'change blur', 'input[name^="payment_method"]', function() {

                    $(document.body).trigger('update_checkout');
                }, 250 );
            });
        })(jQuery);
    </script>

// TO BE COMPLETLY HONEST, I DON'T REALLY KNOW WHAT I WAS SUPPOSED TO DO BELOW
