WordPress is my answer to almost every requirement for web-presence. I’ve used WordPress beyond its capabilities of a CMS — think revision management system, user-management, authentication, REST API… I created themes for bbPress when it was a standalone plugin. Today I also build custom WordPress themes and plugins. Profiles: WordPress: https://profiles.wordpress.org/varun21/, GitHub: https://github.com/sharmashivanand, Email: hello@converticacommerce.com

How to remove billing address fields from WooCommerce checkout form if there are only virtual products in the cart [WooCommerce Code Snippet]

WooCommerce allows you to sell physical as well as digital / virtual / downloadable products. In case of physical products, we need to collect billing and shipping address because goods need to be delivered to the customers. However in case of digital products, we don’t need to deliver goods and so it does not make sense to collect billing address.

This is actually one of the features my client wanted who has an online store where she sells hard cover books as well as digital copies. For smooth checkout process she requested a feature where users ordering digital copies only should not go through the hassle of filling billing address details.

Here’s the code snippet for the same:

add_filter('woocommerce_checkout_fields','wooc_custom_checkout_fields');

function wooc_custom_checkout_fields( $fields ) {
	if( wooc_cart_has_virtual_product() == true ) { //helper function to check if there are only virtual products in the cart
		unset($fields['billing']['billing_first_name']);
		unset($fields['billing']['billing_last_name']);
		unset($fields['billing']['billing_company']);
		unset($fields['billing']['billing_address_1']);
		unset($fields['billing']['billing_address_2']);
		unset($fields['billing']['billing_city']);
		unset($fields['billing']['billing_postcode']);
		unset($fields['billing']['billing_country']);
		unset($fields['billing']['billing_state']);
		unset($fields['billing']['billing_phone']);
	}
	return $fields;
}


function wooc_cart_has_virtual_product() {
	global $woocommerce;
	
	// By default, no virtual product
	$has_virtual_products = false;
	
	// Default virtual products number
	$virtual_products = 0;
	
	// Get all products in cart
	$products = $woocommerce->cart->get_cart();
	
	// Loop through cart products
	foreach( $products as $product ) {
		// Get product ID and '_virtual' post meta
		$product_id = $product['product_id'];
		$is_virtual = get_post_meta( $product_id, '_virtual', true );
		// Update $has_virtual_product if product is virtual
		if( $is_virtual == 'yes' ) {
			$virtual_products += 1;
		}
	}
	if( count($products) == $virtual_products ) { //match the count with the products in the cart
		$has_virtual_products = true;
		}
	return $has_virtual_products;
}
