Symfony 4.1 tree view form without plugins
How can I get to display elements in the EntityType control in the following way:
Group 1
parent
- child
-- second_child
- child
- child
-- second_child
Group 2
parent
- child
-- second_child
------third_child
parent
- child
I have a table that has a relation to itself, this entity have the parent field which defines the parent and children field for next child elements, the level field which determines the depth of nesting.
I tried to manually fill in the array with the elements in such a structure but it did not write to the database:
$data = ;
$data = ['Group 1']['parent'] = $entityElement;
$data = ['Group 1']['- child'] = $entityElement->getChildren()[0];
$data = ['Group 1']['-- second_child'] = $entityElement->getChildren()[1];
->add('elements', ChoiceType::class, [
'mapped' => false,
'expanded' => false,
'multiple' => true,
'choices' => $options['elements'],
'placeholder' => false,
])
I tryed create query for this but it's not working, the elements are mixed up even when I add addOrderBy('c.parent')
->add('elements', EntityType::class, [
'class' => Category::class,
'choice_label' => function($item) { return $item->getIndentName(); },
'expanded' => false,
'multiple' => true,
'query_builder' => function (ElementRepository $er) {
return $er->createQueryBuilder('e')->groupBy('e.parent');
},
'group_by' => function ($choiceValue) {
if (is_null($choiceValue->getBrand())) {
return '';
}
return $choiceValue->getBrand()->getName();
},
])
How should I do that ?
