WooCommerce: Remove “(optional)” From Checkout Field Labels

If a WooCommerce checkout field is set to “not required“, its label will get the “(optional)” suffix. Considering the required fields get the red “*” suffix, you may want to get completely rid of the (optional) string.

Sure, you could be using CSS to hide it… but as usual this is not ideal. With CSS display:none, the string loads and then you hide it; with PHP you avoid the loading in the first place.

So, let’s see how this is done – this snippet is also running on this same website so it should definitely work!

add_filter( 'woocommerce_form_field', 'bbloomer_remove_optional_checkout_fields', 9999 );

	$field = preg_replace('/&nbsp;<span class="optional">(.*?)<\/span>/', '', $field );
	return $field;
}

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
