Symfon2 Spit out 3 text fields with a widget

Question

Can I set a widget such that it can spit out 1-3 text fields depending on the desired format? I have a Coordainate entity with a long and lat field. Some of ours users prefer Degrees Minutes Seconds, some Degrees Minutes, some Decimal. We have customizations to handle this on our current system (Symfony 1.4) and I would like to use these same customization files. I'm sure that's passed in through the options?

Here's my form class:

    <?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';
    }
}

**EDIT: example use of the customization file:

    $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
                        $this->setWidget($field['name'].'_degrees', CustomWidgetExtender::createSfWidget($field, $user, $this));

Answer 1

You can use conditions in your builder method basing on what is in options:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    if(<some state of options>) {
        $builder->add(...);
    }
    // and so on
}

By the way, what do you mean by 'customizations to handle this'?
