Display custom delivery choice on Woocommerce Order totals table

Question

Based on "Update fee dynamically based on radio buttons in Woocommerce checkout" answer code, I have been able add a custom dynamic fee applied on customer delivery choice (with custom delivery option choices).

Here is the working code that I have adapted for my needs:

add_action( 'woocommerce_cart_calculate_fees', 'add_delivery_fee', 20, 1 );
function add_delivery_fee( $cart ) {
    $domain = 'woocommerce';
    $NipostFST = '2000';
    $NIPOSTSUB = '250';

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $packing_fee = WC()->session->get( 'chosen_delivery_option' ); // Dynamic delivery fee
    $Dlabel = $packing_fee == 'home_delivery' ? __('To Your Doorstep', $domain) : __('Local Pickup', $domain);
    $weight_of_item = WC()->cart->cart_contents_weight;

    if ( $weight_of_item > 1 ) {
        $nipostFee = $NipostFST + ( ($weight_of_item - 1)*$NIPOSTSUB );
    }elseif ( $weight_of_item == 1 ) {
        $nipostFee = $NipostFST;
    }

    $fee = (isset($weight_of_item)) ? $packing_fee == 'home_delivery' ? $nipostFee : 0.00 : 'Not Available';
    $cart->add_fee( !is_cart() ? __( 'Delivery Fee [ '.$Dlabel.' ]', $domain ) : __( 'Delivery Fee', $domain ), $fee );
}

// Add a custom radio fields for Delivery Option selection
add_action( 'woocommerce_checkout_before_order_review', 'checkout_delivery_fee_addition', 20 );
function checkout_delivery_fee_addition(){
    $domain       = 'woocommerce';
    $weight_of_item = WC()->cart->cart_contents_weight;

    $NipostFST = '2000';
    $NIPOSTSUB = '250';


    if ( $weight_of_item > 1 ) {
        $nipostFee = $NipostFST + ( ($weight_of_item - 1)*$NIPOSTSUB );
    }elseif ( $weight_of_item == 1 ) {
        $nipostFee = $NipostFST;
    }

    echo '<div id="izzycart_checkout_addons"><tr class="deliveryOption-select"><th>' . __('Delivery Method', $domain) . '</th><td>';

    $chosen   = WC()->session->get('chosen_delivery_option');
    $chosen   = empty($chosen) ? WC()->checkout->get_value('radio_delivery_option') : $chosen;
    $chosen   = empty($chosen) ? 'local_pickup' : $chosen;

    // Add a custom checkbox field
    woocommerce_form_field( 'radio_delivery_option', array(
        'type' => 'radio',
        'class' => array( 'form-row-wide delivery_option' ),
        'options' => array(
            'local_pickup' => __('Local Pickup '.wc_price(0.00), $domain),
            'home_delivery' => (!isset($weight_of_item)) ? __('To Your Doorstep <br><span style="color:red">Not Available</span>', $domain) : __('To Your Doorstep '.wc_price($nipostFee), $domain),
        ),
        'default' => $chosen,
    ), $chosen );

    echo '</td></tr></div>';
}

// Display fees with zero amount
add_filter( 'woocommerce_get_order_item_totals_excl_free_fees', '__return_false' );

My question: In Woocommerce, how I can display the chosen delivery method on order detail table for order received page, My account view order pages and on all email notifications.

So I will like the result to look like this:

Continuation of: Make appear a zero fee in Woocommerce Orders and email notifications

Answer 1

Updated: I have added 2 functions that will grab the selected delivery option to the order and display it in order detail table for order received page, My account view order pages and on all email notifications:

// Save chosen delivery as order custom meta data
add_action('woocommerce_checkout_create_order', 'save_order_delivery_option', 10, 2 );
function save_order_delivery_option(  $order, $data ) {
    if ( isset($_POST['radio_delivery_option']) ) {
        $order->update_meta_data( '_chosen_delivery_method', esc_attr($_POST['radio_delivery_option']) );
    }
}

// Display the chosen delivery information
add_filter( 'woocommerce_get_order_item_totals', 'chosen_delivery_item_order_totals', 10, 3 );
function chosen_delivery_item_order_totals( $total_rows, $order, $tax_display ) {;
    $new_total_rows = [];

    // Loop through Order total lines
    foreach($total_rows as $key => $total ){
        // Get the chosen delivery
        $chosen_delivery = $order->get_meta('_chosen_delivery_method');

        if( ! empty($chosen_delivery) && 'payment_method' === $key ){
            $domain = 'woocommerce';
            $label  = __('Delivery method:', 'woocommerce');
            $value  = 'local_pickup' === $chosen_delivery ? __('Local Pickup', $domain) : __('To Your Doorstep', $domain);
            // Display 'Delivery method' line
            $new_total_rows['chosen_delivery'] = array( 'label' => $label,'value' => $value );
        }
        $new_total_rows[$key] = $total;
    }

    return $new_total_rows;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.
