public function ImageItem::storageSettingsForm in Zircon Profile 8
Same name and namespace in other branches
- 8.0 core/modules/image/src/Plugin/Field/FieldType/ImageItem.php \Drupal\image\Plugin\Field\FieldType\ImageItem::storageSettingsForm()
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
The form definition for the field settings.
