Code

function search_box_form_submit($form, &$form_state) {
  // The search form relies on control of the redirect destination for its
  // functionality, so we override any static destination set in the request,
  // for example by backdrop_access_denied() or backdrop_not_found()
  // (see http://drupal.org/node/292565).
  if (isset($_GET['destination'])) {

  }

  // Check to see if the form was submitted empty.
  // If it is empty, display an error message.
  // This method is used instead of the #required property so that the user
  // will be taken to the search page before the error is shown.
