CP/Alert Service

Simple Example

Alerts are for providing feedback on an action and calling attention to warnings or errors. We describe, in detail, how to build different kinds of alerts in our CP style-guide. We have also created an Alert Service for creating alerts in your code. For example:

ee('CP/Alert')->makeInline('fortune-cookie-form')
      ->asIssue()
      ->withTitle(lang('fortune_cookie_save_error'))
      ->addToBody(lang('fortune_cookie_save_error_desc'))
      ->now();
