PluginFormInterface
interface PluginFormInterface (View source)
Provides an interface for an embeddable plugin form.
Plugins can implement this form directly, or a standalone class can be used. Decoupled forms can implement \Drupal\Component\Plugin\PluginAwareInterface in order to gain access to the plugin.
Methods
Details
array
buildConfigurationForm(array $form, FormStateInterface $form_state)
Form constructor.
Plugin forms are embedded in other forms. In order to know where the plugin form is located in the parent form, #parents and #array_parents must be known, but these are not available during the initial build phase. In order to have these properties available when building the plugin form's elements, let this method return a form element that has a #process callback and build the rest of the form in the callback. By the time the callback is executed, the element's #parents and #array_parents properties will have been set by the form API. For more documentation on #parents and
array_parents, see \Drupal\Core\Render\Element\FormElement.
validateConfigurationForm(array $form, FormStateInterface $form_state)
Form validation handler.
submitConfigurationForm(array $form, FormStateInterface $form_state)
Form submission handler.
