Add Delivery Radio Buttons before order total in WooCommerce checkout - php

Question

I am writing a WordPress plugin in which I need to add two radio buttons before the order total in the WooCommerce Order review section. I figured out how to add custom radio buttons to the order review section but I am unable to get the idea how to move delivery options just before the order total.
Please check the screenshot to understand what exactly I want to achieve.
Here's my code:
// Part 1 - Display Radio Buttons
add_action( 'woocommerce_review_order_before_payment', 'custom_checkout_radio_choice' );
function custom_checkout_radio_choice() {
$chosen = WC()->session->get( 'radio_chosen' );
$chosen = empty( $chosen ) ? WC()->checkout->get_value( 'radio_choice' ) : $chosen;
$chosen = empty( $chosen ) ? '0' : $chosen;
$args = array(
'type' => 'radio',
'class' => array( 'form-row-wide', 'update_totals_on_change' ),
'options' => array(
'2.95' => '60 MINUTES: €2.95',
'0' => '24 - 48 HOURS',
),
'default' => $chosen
);
echo '<div id="checkout-radio">';
echo '<h3>Delivery Options</h3>';
woocommerce_form_field( 'radio_choice', $args, $chosen );
echo '</div>';
}
// Part 2 - Add Fee and Calculate Total
add_action( 'woocommerce_cart_calculate_fees', 'custom_checkout_radio_choice_fee', 20, 1 );
function custom_checkout_radio_choice_fee( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
$radio = WC()->session->get( 'radio_chosen' );
if ( $radio ) {
$cart->add_fee( 'Delivery Fee', $radio );
}
}
// Part 3 - Add Radio Choice to Session
add_action( 'woocommerce_checkout_update_order_review', 'custom_checkout_radio_choice_set_session' );
function custom_checkout_radio_choice_set_session( $posted_data ) {
parse_str( $posted_data, $output );
if ( isset( $output['radio_choice'] ) ){
WC()->session->set( 'radio_chosen', $output['radio_choice'] );
}
}
Please help me out with this.

To move your radio buttons before order total you will need to use another hook. But you can't have that delivery radio buttons on the fee total line…
I have simplified and revisited the code:
add_action( 'woocommerce_review_order_before_order_total', 'checkout_delivery_radio_buttons' );
function checkout_delivery_radio_buttons() {
echo '<tr class="delivery-radio">
<th>'.__("Delivery Options").'</th><td>';
$chosen = WC()->session->get( 'delivery' );
$chosen = empty( $chosen ) ? WC()->checkout->get_value( 'delivery' ) : $chosen;
$chosen = empty( $chosen ) ? '0' : $chosen;
woocommerce_form_field( 'delivery', array(
'type' => 'radio',
'class' => array( 'form-row-wide', 'update_totals_on_change' ),
'options' => array(
'2.95' => '60 MINUTES: €2.95',
'0' => '24 - 48 HOURS',
),
), $chosen );
echo '</td></tr>';
}
add_action( 'woocommerce_cart_calculate_fees', 'checkout_delivery_fee', 20, 1 );
function checkout_delivery_fee( $cart ) {
if ( $radio = WC()->session->get( 'delivery' ) ) {
$cart->add_fee( 'Delivery Fee', $radio );
}
}
add_action( 'woocommerce_checkout_update_order_review', 'checkout_delivery_choice_to_session' );
function checkout_delivery_choice_to_session( $posted_data ) {
parse_str( $posted_data, $output );
if ( isset( $output['delivery'] ) ){
WC()->session->set( 'delivery', $output['delivery'] );
}
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
