How to Hide Fields on Checkout Page for specific Product in the Cart in Woocommerce

Today one of our client wanted to hide the specific field on the checkout page for a specific product contained into the cart in Woocommerce. So here I show you the snippet that I used to remove field on checkout page based on the product.

Open your functions.php file located in wp-content/themes/your-theme-name/ and add the following code at the end of the file or you can create your own plugin to add this snippet.

/**
 * Hides checkout fields based on the products in the cart
 *
 * @param  array $fields
 * @return array
 */
function remove_fields_forspecific_products( $fields ) {
    $cart = WC()->cart->get_cart();

    foreach ( $cart as $item_key => $values ) {
        $product = $values['data'];

        if ( $product->id == 144 ) {
            unset( $fields['billing']['billing_company'] );
            unset( $fields['shipping']['shipping_company'] );
        }
    }

    return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'remove_fields_forspecific_products' );

In above snippet, I removed the billing and shipping company field only if the product ID 144 is in the customer cart.

if you want to do this for multiple products then use all products IDs, see example below

if ( $product->id == 144 || $product->id == 155 )

This snippet will remove the field for the product id 144 and product id 155.
