Instalation

  1. With composer.json

    composer require yavin/symfony-form-tree:^1.0

  2. Add type guesser in your services file (optional):

    <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_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

    use Yavin\Symfony\Form\Type\TreeType;

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', TreeType::class, [
        'class' => Category::class, // tree class
        'levelPrefix' => '-',
        'orderFields' => ['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.
