Im getting a Class not found error on this line:
new \Placas\FrontendBundle\Form\Type\ChoiceOrTextType(),
I have the class at Placas/FrontendBundle/Form/Type.
Here are the codes, the instantation:
namespace Placas\FrontendBundle\Admin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Route\RouteCollection;
use Placas\FrontendBundle\Form\Type\ChoiceOrTextType;
class CategoriaAdmin extends Admin
{
public $last_position = 0;
private $container;
private $positionService;
public function setContainer(\Symfony\Component\DependencyInjection\ContainerInterface $container)
{
$this->container = $container;
}
public function setPositionService(\Pix\SortableBehaviorBundle\Services\PositionHandler $positionHandler)
{
$this->positionService = $positionHandler;
}
protected $datagridValues = array(
'_page' => 1,
'_sort_order' => 'ASC',
'_sort_by' => 'position',
);
protected function configureFormFields(FormMapper $formMapper)
{
$options = array('required' => false, 'label' => 'Imagen');
if ($this->getSubject()->getImageName()) {
$path = $this->getSubject()->getImageName();
$options['help'] = '<img style="width: 300px; border: 1px solid #ccc" src="/images/' . $path . '" />';
}
$formMapper
->add('nombre', 'text', array('label' => 'Nombre', 'required' => false ))
//->add('image', 'file', $options)
->add('activado', 'checkbox', array('label' => 'Activado', 'required' => false ))
->add('menu', new ChoiceOrTextType(), array(
'choices' => array('Option 1' => 'Option 1', 'Option 2' => 'Option 2'),
'required' => false,))
;
}
// Fields to be shown on lists
protected function configureListFields(ListMapper $listMapper)
{
$this->last_position = $this->positionService->getLastPosition($this->getRoot()->getClass());
$listMapper
->addIdentifier('nombre')
->add('activado')
->add('position', array(), array('label' => 'Posición'))
->add('_action', 'actions', array(
'label' => 'Cambio orden',
'actions' => array(
'move' => array('template' => 'PixSortableBehaviorBundle:Default:_sort.html.twig'),
)));
}
protected function configureRoutes(RouteCollection $collection)
{
$collection->add('move', $this->getRouterIdParameter() . '/move/{position}');
}
}
The class:
use Symfony\Component\Form\AbstractType;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Placas\FrontendBundle\DataTransformer\ValueToChoiceOrTextTransformer;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\FormInterface;
use Symfony\Component\Form\FormView;
class ChoiceOrTextType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('choice', 'choice', array(
'choices' => $options['choices'] + array('Other' => 'Other'),
'required' => false,
))
->add('text', 'text', array(
'required' => false,
))
->addModelTransformer(new ValueToChoiceOrTextTransformer($options['choices']))
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setRequired(array('choices'));
$resolver->setAllowedTypes(array('choices' => 'array'));
}
public function buildView(FormView $view, FormInterface $form, array $options)
{
}
public function finishView(FormView $view, FormInterface $form, array $options)
{
}
public function getParent()
{
return 'form';
}
public function getName()
{
return 'tags';
}
}

Im just trying to follow the answer here.

Answer 1

Your ChoiceOrTextType is missing the namespace statement:
<?php
namespace Placas\FrontendBundle\Form\Type;
class ChoiceOrTextType
{
....
}
