Symfon2 用小部件吐出 3 个文本字段

我可以设置一个小部件，使其可以根据所需的格式吐出 1-3 个文本字段吗？ 我有一个具有长而纬度字段的坐标实体。我们的一些用户更喜欢度分秒，一些度分，一些十进制。我们有自定义来处理我们当前系统（Symfony 1.4）上的问题，我想使用这些相同的自定义文件。我确定这是通过选项传入的？

这是我的表单类：

    <?php
   namespace ***'adminBundle'Form;
   use Symfony'Component'Form'AbstractType;
   use Symfony'Component'Form'FormBuilderInterface;
   use Symfony'Component'OptionsResolver'OptionsResolverInterface;
class CoordinateType extends AbstractType
{
        /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('gps84Lat')
            ->add('gps84Long')          
            ->getForm()
        ;
    }
    /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => '***'adminBundle'Entity'Coordinate'
        ));
    }
    /**
     * @return string
     */
    public function getName()
    {
        return '***_adminbundle_coordinate';
    }
}

**编辑：自定义文件的示例使用：

    $custom = $options['attr']['customization_file'];
    $cf     = $custom['form'];
            if(!array_key_exists(0, $cf['fields']['field']))
                    $cf['fields']['field']  = array($cf['fields']['field']);
            foreach($cf['fields']['field'] as $field)
            {
                if(in_array($field['name'], array('gps_84_lat', 'gps_84_long')))
                {
                    if($field['format'] == 'dms')
                    {
                        // standard degrees-minutes-seconds GPS field
                        if($field['name'] == 'gps_84_lat')
                            $gps    = $this->getObject()->getGps84Lat();
                        elseif($field['name'] == 'gps_84_long')
                            $gps    = $this->getObject()->getGps84Long();
                        else
                            $gps    = '';
                        // degrees
