QUESTION snippet for checkout semplification

[manuele]

Hi!
I'd like to simplify the checkout form in case only free products are in the chart.
For this simple purpose I thought to integrate a little snippet using the "Woody snippets" plugin with this code:

<?php
/**
 * @snippet     Simplify free WooCommerce checkout if cart does not need payment
 * @resources
 *                 tutorial https://www.skyverge.com/blog/how-to-simplify-free-woocommerce-checkout/
 *                gist     https://gist.github.com/bekarice/474ab82ab37b8de8617d
 */

if ( !is_null(WC()->cart) && (WC()->cart->total)==0 ) {
    // remove coupon forms since why would you want a coupon for a free cart??
    remove_action( 'woocommerce_before_checkout_form', 'woocommerce_checkout_coupon_form', 10 );
    // Remove the "Additional Info" order notes
    add_filter( 'woocommerce_enable_order_notes_field', '__return_false' );
    // Unset the fields we don't want in a free checkout
    function unset_unwanted_checkout_fields( $fields ) {
        // add or remove billing fields you do not want
        // fields: http://docs.woothemes.com/document/tutorial-customising-checkout-fields-using-actions-and-filters/#section-2
        $billing_keys = array(
            //'billing_last_name',
            'billing_company',
            'billing_phone',
            'billing_address_1',
            'billing_address_2',
            'billing_city',
            'billing_postcode',
            'billing_country',
            'billing_state',
        );
        // unset each of those unwanted fields
        foreach( $billing_keys as $key ) {
            unset( $fields['billing'][ $key ] );
            // unset( $fields['billing'][ $key ]['required'] );
        }
        return $fields;
    }
    add_filter( 'woocommerce_checkout_fields', 'unset_unwanted_checkout_fields' );
}
?>

Applying the script to the checkout page I can actually see a lighter form without the unwanted fields but it seams the code is not considered when the form is submitted via AJAX to the service address https://<my site host>/?wc-ajax=checkout so despite if I cannot see the unwanted fields they are however checked, the form is not validated and the service response replays with this response:

{"result":"failure","messages":"<div class=\"woocommerce-error row-container row-message\">\n\t<div class=\"row-parent no-h-padding no-top-padding double-bottom-padding\">\n\t\t<ul class=\"woocommerce-error-list woocommerce-error\" role=\"alert\">\n\t\t\t\t\t\t\t<li><strong>Cognome di fatturazione<\/strong> \u00e8 un campo obbligatorio.<\/li>\n\t\t\t\t\t\t\t<li><strong>Provincia di fatturazione<\/strong> \u00e8 un campo obbligatorio.<\/li>\n\t\t\t\t\t\t\t<li><strong>Telefono di fatturazione<\/strong> \u00e8 un campo obbligatorio.<\/li>\n\t\t\t\t\t<\/ul>\n\t<\/div>\n<\/div>\n","refresh":false,"reload":false}

How can I fix it?
Thank you very much in advance.

Best regards

Manuele

Hello.

You remove from the form fields that are required. Contact Woocommerce support with the question how to make the fields optional or read your own link in the code.
