I created a custom registration form, one of the fields is being validated using a third party API.

If the field passes validation later I update_user_meta.

Currently if the field fails validation I add an error using wc_add_notice().

The problem is, I need to do something different depending on if it failed because the data didn't pass validation or it failed because the API is down. I have the logic to tell which fail it is, I'm just not sure what to do with it.

Here is a sample of my validation function.

function add_registration_validation($username, $email, $validation_errors) {       
    $billing_npi = sanitize_text_field($_POST['billing_npi']);

    if (isset($_POST['billing_npi']) && empty($_POST['billing_npi'])){ // empty
        $validation_errors->add('billing_npi_error', __(' NPI is required!', 'woocommerce'));
    }else{
        // NPI API Validation
        $npiURL = 'https://npiregistry.cms.hhs.gov/api/?number=' . $billing_npi . '&version=2.1';
        $add_order_response = wp_remote_get($npiURL);

        if (is_array($add_order_response) && !is_wp_error($add_order_response)) {

            // Failed So Send Error 

           $json_decoded_add_order_response = json_decode($add_order_response['body']);

            if ($json_decoded_add_order_response->result_count < 1) {
                $validation_errors->add('billing_npi_error', __(' Your NPI number does not match our records!', 'woocommerce'));
            } 
        }else{

            // Failed Because API is down

            // holds error msg
            // $error_string = $add_order_response->get_error_message();
        }       
    }

    ...

    return $validation_errors;
}

add_action('woocommerce_register_post', 'add_registration_validation', 10, 3);

You can see in the comments the 2 different fail types.

What I need to happen is this...

If it fails because it didn't match the API I throw an error stopping the form from submitting, which is working fine.

But if it fails because the API is down, I want to submit the form as normal but create a flag letting me know the API was down at the time. I think I need to set a variable and update a hidden input, but can't figure out how to do this.

Here is how I am saving the data.

function add_registration_meta($customer_id) {
    if (isset($_POST['billing_npi'])) {
        update_user_meta($customer_id, 'billing_npi', sanitize_text_field($_POST['billing_npi']));
    }
}

add_action('woocommerce_created_customer', 'add_registration_meta');

Hopefully that makes sense! I'm open to any suggestions, thank you!
