WooCommerce: Dynamically Hide / Show Checkout Field

We already saw a lot of examples e.g. hiding checkout fields if a product is virtual or hiding checkout fields if a checkbox is manually checked… but this time I want to hide a field dynamically – automatically – based on whether another checkout field is empty or has a specific value.

In this example, I will demonstrate how to hide the “billing phone” if “billing company” is empty or no information is entered. Of course, you also have to disable the mandatory attribute for the billing phone from the Customizer settings, otherwise checkout validation will fail. You can readapt this snippet to any other checkout field combo – just identify the input IDs and change jQuery accordingly. Enjoy!

In this example, we will see how to hide and keep hidden the Billing Phone entire field unless some content is entered inside Company name field

add_action( 'woocommerce_after_checkout_form', 'bbloomer_conditionally_hide_show_checkout_field', 9999 );
 
function bbloomer_conditionally_hide_show_checkout_field() {
	wc_enqueue_js( "
		$('#billing_company').keyup(function() {
			if ($(this).val().length == 0) {
				$('#order_comments_field').hide();
			} else {
				$('#order_comments_field').show();
			}
		});
	" );
}

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.

  1. Hi Rodolfo,
    great snippet!
    But how to edit it if you wanna show/hide a field depending on values of a dropdown?
    Thanks

    1. Hey Gio, thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  2. Hey Mate,
    Is It possible to Hide all the shipping fields until the Address is fulfilled?
    I’ve Installed the Google Places API and a plugin that transfer the information to the rest of the fields when the Address is completed.

    I’ve tried to modify your script but something is not working. can you have a look?
    Thanks!
