public function GoogleCSESearch::searchFormAlter in Google Custom Search Engine 8.2

Same name and namespace in other branches

1. 8.3 src/Plugin/Search/GoogleCSESearch.php \Drupal\google_cse\Plugin\Search\GoogleCSESearch::searchFormAlter()

Alters the search form when being built for a given plugin.

The core search module only invokes this method on active module plugins when building a form for them in \Drupal\search\Form\SearchPageForm::buildForm(). A plugin implementing this will also need to implement the buildSearchUrlQuery() method.

Parameters

array $form: Nested array of form elements that comprise the form.

\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form. The arguments that \Drupal::formBuilder()->getForm() was originally called with are available in the array $form_state->getBuildInfo()['args'].

Overrides SearchPluginBase::searchFormAlter
