Symfony2 JsonResponse - ordering by value - json

Question

I have 2 dropdowns were content of the second one depends on the first one. I produce it's content by generating an array and passing it to JsonResponse
new JsonResponse($response_object);
My $response_object is created based on the list in the database where array keys match entity ID:
6 => 'A Item',
3 => 'B Item',
1 => 'C Item',
10 => 'D Item'
Problem is, that even tho I'm passing that list to JsonResponse as displayed (sorted by value), it displays it in the dropdown ordered by the key, not value.
This is how I build the response_object
foreach ($entities as $entity) {
$response_object->entities[$entity->getId()] = $entity->getName()
}
$response = new JsonResponse($response_object);
return $response;
Twig is a simple for widget
{{ form_widget(select_current_form.entity) }
Config in form builder for this particular field is
->add('entity', 'choice', array('required' => false, 'choices' => $entity_choices))
How to force it to display the list in order by value?

Answer 1

You can maybe try to use string as key in your array. Remember that you can use natsort to easily sort your array.

Answer 2

Instead of passing an array to the JsonResponse, if you pass an object you will be able to preserve its sorting.
Instead of this,
6 => 'A Item',
3 => 'B Item',
1 => 'C Item',
10 => 'D Item'
Arrange your function to bring an array of objects like this. (In PDO, you can use \PDO::FETCH_OBJ fetch mode)
[0] => stdClass Object
(
[id] => 6
[value] => A Item
)
[1] => stdClass Object
(
[id] => 3
[value] => B Item
)
[2] => stdClass Object
(
[id] => 1
[value] => C Item
)
[3] => stdClass Object
(
[id] => 10
[value] => D Item
)
I hope someone will find this helpful.
