ZF2 nested data validation - zend-framework2

Question

I'm trying make to work my validation. I have data posted to controller in the format like this:
[
'property' => 'value',
'nested_property' => [
'property' => 'value',
// ...
]
]
I have divided fields/filters and form into different classes and just gather it together in the Form's controller that looks like that:
public function __construct($name, $options)
{
// ...
$this->add(new SomeFieldset($name, $options));
$this->setInputFilter(new SomeInputFilter());
}
But it doesn't work properly, looks like it just ignores nested array (or ignores everything). What have I missed?
Thank you.

You need to set up your inputfilter like the way you've setup your forms including the fieldsets if you use the InputFilter class.
So when you've got a structure like:
MyForm
1.1 NestedFieldset
1.2 AnotherFieldset
Your inputfilters need to have the same structure:
MyFormInputFilter
1.1 NestedFielsetInputFilter
1.2 AnotherFieldsetInputFilter
Some example code:
class ExampleForm extends Form
{
public function __construct($name, $options)
{
// handle the dependencies
parent::__construct($name, $options);
$this->setInputFilter(new ExampleInputFilter());
}
public function init()
{
// some fields within your form
$this->add(new SomeFieldset('SomeFieldset'));
}
}
class SomeFieldset extends Fieldset
{
public function __construct($name = null, array $options = [])
{
parent::__construct($name, $options);
}
public function init()
{
// some fields
}
}
class ExampleInputFilter extends InputFilter
{
public function __construct()
{
// configure your validation for your form
$this->add(new SomeFieldsetInputFilter(), 'SomeFieldset');
}
}
class SomeFieldsetInputFilter extends InputFilter
{
public function __construct()
{
// configure your validation for your SomeFieldset
}
}
So the important part of configuring your inputFilter for these situations is that you need to reuse the name of your fieldset when using: $this->add($input, $name = null) within your InputFilter classes.
