Display ALL available shipping methods for each specific order on admin edit order pages in Woocommerce

Question

On the checkout page of my WooCommerce based site, users will have a list of shipping methods to choose from depending on what they are purchasing

This is the list I want to capture:

---

Things like

• “Free Shipping” for orders over a certain price
• “Freight Shipping” for certain items, and so on.

My goal, is to display ALL available methods for each specific order, and display it on the “Edit Order / Order Details” page in the Admin view.

A small feature that would help us be able to quickly identify what option people are choosing more often, depending on the choices that they have available.

This is what I have so far:

add_action( 'woocommerce_checkout_update_order_meta', 'save_available_shipping_methods' );
 
function save_available_shipping_methods( $order_id ) {
    $shippingmethods = WC()->cart->get_shipping_methods();
    update_post_meta( $order_id, '_shipping_methods', $shippingmethods );
}

add_action( 'woocommerce_admin_order_data_after_shipping_address', 'get_available_shipping_methods', 10, 1 );

function get_available_shipping_methods($order){
    $order = wc_get_order( $order_id );
    if ( $order ) {
        echo '<p><strong>'.__('Available Shipping Methods: ').'</strong> ' . get_post_meta($order->get_shipping_methods(), '_shipping_field_value', true ) . '</p>';
    }
}

I'll attach a picture as well to maybe make things a little easier to follow.

This is where I would like to put it. The current hook places the field underneath the shipping address

Answer 1

• In the woocommerce_checkout_update_order_meta hook, the available shipping packages are stored via update_post_meta
• Comments with explanation added in the code

function action_woocommerce_checkout_update_order_meta( $order_id ) {
    // Get shipping packages
    $packages = WC()->shipping()->get_packages();
    
    // Set array
    $rate_labels = array();
    
    // Loop trough packages
    foreach ( $packages as $key => $package ) {
        // Loop through package rates
        foreach( $package['rates'] as $rate_id => $rate ) {
            // Push to array
            $rate_labels[] = $rate->get_label();
        }
    }

    // NOT empty
    if ( ! empty ( $rate_labels ) ) {
        // Update post meta
        update_post_meta( $order_id, '_available_shipping_methods', $rate_labels );
    }
}
add_action( 'woocommerce_checkout_update_order_meta', 'action_woocommerce_checkout_update_order_meta', 10, 1 ); 

// Display on the order edit page (backend)
function action_woocommerce_admin_order_data_after_shipping_address( $order ) {
    // Get meta
    $rate_labels = $order->get_meta( '_available_shipping_methods' );
    
    // True
    if ( $rate_labels ) {
        // Loop trough rate labels
        foreach( $rate_labels as $rate_label ) {
            // Output
            echo '<p>' . $rate_label . '</p>';
        }
    }
}
add_action( 'woocommerce_admin_order_data_after_shipping_address', 'action_woocommerce_admin_order_data_after_shipping_address', 10, 1 );
