How to validate array items in Symfony 2.3? - php

Question

I use Symfony v2.3.x and I have a validation file that looks something like this:
Namespace\To\MyEntity:
properties:
entityCollection:
- Type: { groups: [mygroup], type: array }
- All:
constraints:
- Type: { groups: [mygroup], type: Namespace\To\AnotherEntity }
So MyEntity must contain an array of AnotherEntitys in the entityCollection field.
It successfully validates that entityCollection must be an array. However, it fails to validate that the elements of that array are of the specified type.
For example, these two var_dumps both show the value 0 on the screen even though I expect something non-zero:
$obj = new MyEntity();
$obj->entityCollection = array(12345);
$errors = $symfonyValidator->validate($obj, array('mygroup'));
var_dump(count($errors));
$obj = new MyEntity();
$obj->entityCollection = array("something");
$errors = $symfonyValidator->validate($obj, array('mygroup'));
var_dump(count($errors));
I even tried removing the constraints entry from the validation file; it made no difference.
I looked at Symfony's official page about the All keyword but I couldn't find anything that would work.
How should I modify the entry in my validation.yml file so that the validation works as intended ?
Thank you in advance.

Your configs look fine, although I'm more accustomed to having them as annotations so it's clear what entity properties they apply to. Have you tried:
$errors = $symfonyValidator->validate($obj, array('mygroup'), true);
The 3rd parameter to the validate() method is a boolean for traversing the object you're validating.
bool $traverse Whether to traverse the value if it is traversable.
