I'm building a shop based on WooCommerce. I need to add an extra checkbox on the checkout page called Shipping Insurance. Once the field is checked, i need to add an extra $3 to the Order Total. I was able to add a fixed fee this way:

function woo_add_cart_fee() {
  global $woocommerce;
  $woocommerce->cart->add_fee( __('Shipping Insurance', 'woocommerce'), 3 );

}
add_action( 'woocommerce_before_calculate_totals', 'woo_add_cart_fee' );

The problem is that this will add a fixed $3 to the order total, so its not optional. Any idea how to proceed with this issue?

Ok, so this is how i did it.

Create a product called Shipping Insurance which is $3, make sure its a hidden product(Catalog Visibility on the right side)

Use the following code in your theme's functions.php file:

add_action('woocommerce_cart_totals_after_shipping', 'wc_shipping_insurance_note_after_cart');
function wc_shipping_insurance_note_after_cart() {
global $woocommerce;
    $product_id = 669;
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
    $_product = $values['data'];
    if ( $_product->id == $product_id )
        $found = true;
    }
    // if product not found, add it
if ( ! $found ):
?>
    <tr class="shipping">
        <th><?php _e( 'Shipping Insurance', 'woocommerce' ); ?></th>
        <td><a href="<?php echo do_shortcode('[add_to_cart_url id="669"]'); ?>"><?php _e( 'Add shipping insurance (+$3)' ); ?> </a></td>
    </tr>
<?php else: ?>
    <tr class="shipping">
        <th><?php _e( 'Shipping Insurance', 'woocommerce' ); ?></th>
        <td>$3</td>
    </tr>
<?php endif;
}

Change the $product_id variable to your product id that you created and when you're on checkout, it will simply add this hidden product to your cart

This won't completely answer your question, but the official WooCommerce documentation has an example similar to what you are hoping to achieve. In particular, you are looking for a combination of Lessons 1 and 2.
