Instalation

1. With composer.json

   composer require yavin/symfony-form-tree:0.4
   

2. Add services in your services file:

   <service class="Yavin\Symfony\Form\Type\TreeType">
       <argument type="service" id="property_accessor"/>
       <tag name="form.type" alias="y_tree"/>
   </service>
   <service class="Yavin\Symfony\Form\Type\TreeTypeGuesser">
       <argument type="service" id="doctrine"/>
       <tag name="form.type_guesser"/>
   </service>

   or if you use yml format:

   services:
       symfony.form.type.tree:
           class: Yavin\Symfony\Form\Type\TreeType
           arguments: [ "@property_accessor" ]
           tags:
               - { name: form.type, alias: y_tree }
       symfony.form.type_guesser.tree:
           class: Yavin\Symfony\Form\Type\TreeTypeGuesser
           arguments: [ "@doctrine" ]
           tags:
               - { name: form.type_guesser }

3. Then add field to tree model. In this example

   public function buildForm(FormBuilderInterface $builder, array $options)
   {
       $builder->add('category'); //extension will guess field type
   
       //or this is full example with default options:
   
       $builder->add('category', 'y_tree', array(
           'class' => 'Acme\DemoBundle\Entity\Category', // tree class
           'levelPrefix' => '-',
           'orderFields' => array('treeLeft' => 'asc'),
           'prefixAttributeName' => 'data-level-prefix',
           'treeLevelField' => 'treeLevel',
       ));
   }

   This extension assume that in tree model You have treeLeft and treeLevel fields. It can be changed in field options.

   Here is example tree entity.
