Remove Email and Phone Number

here’s an example that removes the fields from all templates. uncomment the two lines to remove them only from the receipt. place the code in the functions.php:

function example_remove_order_info_fields( $fields, $order ) {
	//if( wcdn_get_template_type() == 'receipt' ) {
		unset( $fields['billing_email'] );
		unset( $fields['billing_phone'] );
	//}

	return $fields;
}
add_filter( 'wcdn_order_info_fields', 'example_remove_order_info_fields', 10, 2 );
