Default WooCommerce checkout form comes with several fields for customers to enter their billing details. But in some cases, you might want to hide some of these fields. For example, if you are selling only virtual products, you can get rid of fields like billing address.

Use the following code snippet to remove or hide fields from WooCommerce checkout page.

//Remove Billing Details Fields from WooCommerce Checkout Page
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
 
function custom_override_checkout_fields( $fields ) {
    unset($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($fields['billing']['billing_phone']);
    unset($fields['order']['order_comments']);
    unset($fields['billing']['billing_email']);
    unset($fields['account']['account_username']);
    unset($fields['account']['account_password']);
    unset($fields['account']['account_password-2']);
    return $fields;
}

/**

 * @return string
 */
function custom_add_to_cart_redirect() { 
    return 'http://www.yourdomain.com/your-page/'; 
}
add_filter( 'woocommerce_add_to_cart_redirect', 'custom_add_to_cart_redirect' );
