public function CountryItem::storageSettingsForm in Country 8

Returns a form for the storage-level settings.

Invoked from \Drupal\field_ui\Form\FieldStorageConfigEditForm to allow administrators to configure storage-level settings.

Field storage might reject settings changes that affect the field storage schema if the storage already has data. When the $has_data parameter is TRUE, the form should not allow changing the settings that take part in the schema() method. It is recommended to set #access to FALSE on the corresponding elements.

Parameters

array $form: The form where the settings form is being included in.

\Drupal\Core\Form\FormStateInterface $form_state: The form state of the (entire) configuration form.

bool $has_data: TRUE if the field already has data, FALSE if not.

Return value

array The form definition for the field settings.
