如何从选择选项中获取所选项目的值在symfony？（来自以下文章）

我的表单中包含该配置：

$this->widgetSchema['category_id'] = new sfWidgetFormDoctrineChoice(array(
        'model'     => 'Category',
        'method'    => 'getLibelleCat',
        'add_empty' => 'select category'
 ));

$this->widgetSchema['article_id'] = new sfWidgetFormDoctrineDependentSelect (array(
        'model'     => 'Article',
        'method'    => 'getLibelle',
        'depends'   => 'Category',
        'add_empty' => 'select article'

));
