title: Title with error prefix
---

markdown:
  If you have a page containing a form, you should add the "Error: " prefix to the page title if there is a validation error on the page.

  This means that screen readers will read it out as soon as possible.

  To do this, you can use the `title_with_error_prefix` helper.

  If you are using a Rails form, you can set the error attribute by calling `errors.any?` on the form object:

  ```
    = title_with_error_prefix("Personal details", error: @personal_details_form.errors.any?)
  ```

== render('/partials/example.*',
  caption: "Title with an error present",
  code: title_containing_error)

== render('/partials/example.*',
  caption: "Title with an error present",
  code: title_not_containing_error)

== render('/partials/example.*',
  caption: "Title with a custom error prefix",
  code: title_containing_error_and_custom_error_prefix)
