WooCommerce required fields error

Question

I have made a custom design for my WooCommerce checkout and for the longest time it worked just fine, however it seems recently I can no longer checkout. Even if I fill out all the fields I get an error saying that I must fill out certain fields. This is the code that I use and I am looking to either fix it so that it only requires the fields that I have in this code or worst case to just write a code so it never demands anything to be filled out.

I have done some further testing and I am using only billing fields, but the errors are appearing for shipping fields. I need to make shipping and billing fields one and the same or to just no longer have shipping fields required as the billing fields seem to work perfectly.

function custom_override_checkout_fields( $fields ) {
    unset($fields['billing']['billing_company']);
    unset($fields['billing']['billing_country']);
    unset($fields['billing']['billing_address_2']);

    return $fields;
}

add_filter( 'woocommerce_package_rates', 'my_hide_shipping_when_free_is_available', 100 );

add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );


// for billing fields

    add_filter("woocommerce_checkout_fields", "new_order_fields");

        function new_order_fields($fields) {

            $order = array(

Answer 1

I found a solution:

//make shipping fields not required in checkout
add_filter( 'woocommerce_shipping_fields', 'wc_npr_filter_shipping_fields', 10, 1 );
function wc_npr_filter_shipping_fields( $address_fields ) {
	$address_fields['shipping_first_name']['required'] = false;
	$address_fields['shipping_last_name']['required'] = false;
	$address_fields['shipping_address_1']['required'] = false;
	$address_fields['shipping_city']['required'] = false;
	$address_fields['shipping_postcode']['required'] = false;
		return $address_fields;
}
