Form Select in ZF2

formselectinzf2

namespace SampleModule\Form;

use Zend\Form\Form;

class SampleForm extends Form
{
    public function __construct($name = null)
    { 
        parent::__construct('Sample Form');

        $this->add(array(
            'type' => 'Zend\Form\Element\Select',
            'name' => 'gender',
            'options' => array(
                'label' => 'Gender',
                'value_options' => array(
                    '1' => 'Select your gender',
                    '2' => 'Female',
                    '3' => 'Male'
                ),
            ),
            'attributes' => array(
                'value' => '1' //set selected to '1'
            )
        ));
    }
}

For inputfilter :
namespace SampleModule\Model;

use Zend\InputFilter\Factory as InputFactory;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;

class Sample implements InputFilterAwareInterface
{
    public $gender;
    
    protected $inputFilter;

    public function exchangeArray($data)
    {
        $this->gender = (isset($data['gender'])) ? $data['gender'] : null;
    }
    
    public function getArrayCopy()
    {
        return get_object_vars($this);
    } 
    
    public function setInputFilter(InputFilterInterface $inputFilter)
    {
        throw new \Exception("Not used");
    }

    public function getInputFilter()
    {
        if (!$this->inputFilter) {
            $inputFilter = new InputFilter();
            $factory     = new InputFactory();

            $inputFilter->add($factory->createInput(array(
                'name'     => 'gender',
                'validators' => array(
                    array(
                        'name'    => 'InArray',
                        'options' => array(
                            'haystack' => array(2,3),
                            'messages' => array(
                                \Zend\Validator\InArray::NOT_IN_ARRAY => 'Please select your gender !'  
                            ),
                        ),
                    ),
                ),
            ))); 
          

            $this->inputFilter = $inputFilter;
        }

        return $this->inputFilter;
    }
}

This is more a hack than a real solution for the InArray Validator problem.
