Defines the various handler objects to help build and display views.

Class

views_handler
Base handler, from which all the other handlers are derived. It creates a common interface to create consistency amongst handlers and data.

Code

public function show_expose_form(&$form, &$form_state) {
  if (empty($this->options['exposed'])) {
    return;
  }
  $this
    ->expose_form($form, $form_state);

  // When we click the expose button, we add new gadgets to the form but they
  // have no data in $_POST so their defaults get wiped out. This prevents
  // these defaults from getting wiped out. This setting will only be TRUE
  // during a 2nd pass rerender.
  if (!empty($form_state['force_expose_options'])) {
    foreach (element_children($form['expose']) as $id) {
      if (isset($form['expose'][$id]['#default_value']) && !isset($form['expose'][$id]['#value'])) {
        $form['expose'][$id]['#value'] = $form['expose'][$id]['#default_value'];
      }
    }
  }
}
