ZF2 nested data validation


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.


Solution

  • 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:

    1. MyForm
      1.1 NestedFieldset
      1.2 AnotherFieldset

    Your inputfilters need to have the same structure:

    1. 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.
