Process forms

While Connect Platform for Optimizely Data Platform (ODP) renders settings forms, your app is responsible for processing and saving the data users submit through the form. Your app's lifecycle handler includes an onSettingsForm method to handle form submission from the settings form.

When your app receives a request to handle actions on the settings form, you should verify the data, perform any remote configuration required at that time, and, if everything is successful, save the data to the settings store. Or, if there are errors, create helpful error messages for the user.

Users can only edit one section of a form at a time, so you do not have to worry about validating across sections simultaneously. However, you may wish to use the configuration from other sections when validating user selections. As with any other functions, you have complete access to the settings store to read any other configuration saved by the user if needed.

Return responses and errors

The onSettingsForm handler is expected to return a LifecycleSettingsResult. You can provide error messages and/or toast notifications to the user, and even send them to another next section of your settings form through the LifecycleSettingsResult.

Use addError to display an error below a particular form element or addToast to display a toast notification to the user.

Direct users to another section

When handling a submission through onSettingsForm, you can move the user to a new form section. For example, after a user submits their credentials in an auth section, if successful, you should move them to a configuration section so they know there is more to do before the integration starts working.

if (Authorized(formData)) {
  result.addToast('success', 'Authenticated!');
  result.redirectToSettings('configure');
} else {
  result.addToast('error', 'Invalid username or password. Please check your credentials and try again.');
}

Set the default section

The most useful section for a user to see is not always the first one. When a user opens the Settings tab of your app in the Optimizely Data Platform (ODP) App Directory, you may want to display another section by default. For example, after authentication is complete, there is no reason to show the auth section even if it makes sense as the first section. You can change the default section at any time by using Form.setDefaultSection.

With the following example, the next time the user opens the Settings tab of your app in the ODP App Directory, the Configure section displays by default:

await Form.setDefaultSection('configure');

Best practices

• Always provide helpful information to the user in both success and error cases. For example, "Successfully scheduled your import job. You will see new data populate within the next hour." Or "Authorization successful" rather than relying on a generic success message.
• Use form predicates to display instructions to the user. For example, you can display instructions inline in the form after authorization is complete using a visibility predicate and a page property rather than trying to provide lengthy instructions in a toast notification.
• Always save necessary form data when successful to ensure the form remains updated and the user can visually see their changes.
• Always direct the user to the desired section. For example, have authentication in a separate section from other configuration options, and send the user to the most useful section by setting the default section as well as redirecting the user after they complete a section.

Example

/**
   * Handle a submission of a form page/section. You are responsible for performing any validation or
   * changes to the form data and then writing it to the settings store for the page.
   * @param page the name of the page/section submitted
   * @param action the action of the button that triggered the call, or 'save' by default
   * @param formData the data for the section as a hash of key/value pairs
   * @param result the response to return. Add any errors or toasts to the result before returning it.
   * @returns {LifecycleSettingsResult} with any errors that should be displayed to the user
