I have an Entity containing Self-Referenced mapping.
class Category
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=100)
*/
private $name;
/**
* @ORM\OneToMany(targetEntity="Category", mappedBy="parent")
*/
private $children;
/**
* @ORM\ManyToOne(targetEntity="Category", inversedBy="children")
* @ORM\JoinColumn(name="parent_id", referencedColumnName="id")
*/
private $parent;
}
In my CategoryType I have this :
public function buildForm(FormBuilderInterface $builder, array $options)
{
$plan = $this->plan;
$builder->add('name');
$builder->add('parent', 'entity', array(
'class' => 'xxxBundle:Category',
'property' => 'name',
'empty_value' => 'Choose a parent category',
'required' => false,
'query_builder' => function(EntityRepository $er) use ($plan) {
return $er->createQueryBuilder('u')
->where('u.plan = :plan')
->setParameter('plan', $plan)
->orderBy('u.id', 'ASC');
},
));
}
Actually, when I render the form field Category this is something like
Cat1
Cat2
Cat3
Subcat1
Subcat2
Cat4
I would like to know if it's possible and how to display something more like, a kind of a simple tree representation :
Cat1
Cat2
Cat3
-- Subcat1
-- Subcat2
Cat4
Regards.
