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'];
            }
        }
    }
