In WooCommerce checkout form I have a checkbox for customers who are willing to buy as a company. If the checkbox is checked - two fields reveal via js - default billing_company and custom billing_company_vat. What I'm trying to archive that if the checkbox is unchecked then these two fields won't be saved in order meta.

JS for showing/hiding checkout fields:

// checking if checkbox is checked on page load
if (!jQuery('body #checkbox_trigger').is(":checked")) 
 jQuery('body #billing_company_field, body #billing_company_vat_field').hide();


// show/hide on checkbox check
jQuery('body #checkbox_trigger').change(function() 
 if(jQuery(this).is(":checked")) 
 jQuery('body #billing_company_field, body #billing_company_vat_field').show();
 
 else 
 jQuery('body #billing_company_field, body #billing_company_vat_field').hide();
 
);

PHP for deleting billing_company and billing_company_vat fields from order meta if checkbox is unchecked:

add_action( 'woocommerce_checkout_update_order_meta', 'checkout_company_fields', 10, 2 );
function checkout_company_fields( $order_id, $posted ) 
 if (isset($posted['checkbox_trigger']) && !$posted['checkbox_trigger']) 
 delete_post_meta($order_id, '_billing_company');
 delete_post_meta($order_id, '_shipping_company');
 delete_post_meta($order_id, '_billing_company_vat');
 

This works and does what I need but I have a sense that this is somehow wrong and shouldn't be done this way - I guess that all checkout field data is sent to the payment gateway and is deleted from order meta only afterward when checkout is complete. I believe these two fields should be "unset" before sending the data to the payment gateway (PayPal etc.)

Also sometimes there is fatal error coming from payment gateway not sure if it's related.
