Using a WooCommerce site we sell electronic parts and offer free next-day delivery as standard, but also next day pre 10 and Saturday morning deliveries as a paid upgrade. As these are the exceptions rather than the rule in our orders, I miss them. I’ve tried adding ***** and other such characters to the description but they just dont stand out enough to make me notice them. I therefore want to change the background color in the order table based on the shipping method, so I do not upset customers.

I found this (which as far as I can tell uses “local pickup” but need to make it based on $shipping_method_id = 3,5,13

Anyone able to help ?

function filter_post_class( $classes, $class, $post_id ) {
// Determines whether the current request is for an administrative interface page
if ( ! is_admin() ) return $classes;

// Get the current screen object
$current_screen = get_current_screen();

// Only when
if ( $current_screen->id === 'edit-shop_order' ) {
    // Get an instance of the WC_Order object
    $order = wc_get_order( $post_id );

    // Is a WC_Order
    if ( is_a( $order, 'WC_Order' ) ) {
        // Get the shipping method
        $shipping_method = @array_shift($order->get_shipping_methods());
        $shipping_method_id = $shipping_method['method_id'];
        
         //NOT empty
        if ( ! empty( $shipping_method ) ) {
            $classes[] = $shipping_method_id;
        }
    }
}

// Return the array
return $classes;
}
add_filter( 'post_class', 'filter_post_class', 10, 3 );

// Add CSS
function action_admin_head() {
// Get the current screen object
$current_screen = get_current_screen();

// Only when
if ( $current_screen->id === 'edit-shop_order' ) {
    echo '<style>
        .type-shop_order.local_pickup {
            background-color: #e9a5a5 !important;
        }
        
    </style>';
}
}
add_action( 'admin_head', 'action_admin_head' );
