Question

我试图在zend框架2中验证一个简单的表单几天了。我检查了文档和很多考虑这个主题的帖子，但我找不到解决方案！

我有一个非常简单的形式：

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

    $this->add(array(
        'required'=>true,
        'name' => 'year',
        'type' => 'Text',
        'options' => array(
            'label' => 'Jahr',
        ),
    ));
    $this->add(array(
        'required'=>true,
        'name' => 'number',
        'type' => 'Text',
        'options' => array(
            'label' => 'Number',
        ),
    ));
    $this->add(array(
        'name' => 'submit',
        'type' => 'Submit',
        'attributes' => array(
            'value' => 'Go',
            'id' => 'submitbutton',
        ),
    ));
}
}

我创建了一个自定义的InputFilter：

namespace Application\Form;

use Zend\InputFilter\InputFilter;
class AlimentInputFilter extends InputFilter {
    public function init()
    {
    $this->add([
        'name'       => AlimentForm::year,
        'required'   => true,
        'validators' => array(
          array(
              'name' => 'Between',
              'options' => array(
                  'min' => 1900,
                  'max' => 3000,
              ),
          ),
        ),
    ]);
}
}

最后在我的控制器中我尝试验证表单

public function alimentAction(){
    $form = new AlimentForm();

    $form->setInputFilter(new AlimentInputFilter());

    $request = $this->getRequest();
    if ($request->isPost()) {
       $form->setData($request->getPost());

       if ($form->isValid()) {
           $year = $form->get('year')->getValue();
           $number = $form->get('number')->getValue();

           return array('result' => array(
               "msg" => "In the Year ".$year." you get ".$number." Points"
           ));
       }
    }
    return array('form' => $form);
}

这不是那么困难，但是从所有那些不同的方式来验证我在网上找到的表格，我有点困惑......

我错过了什么？

好的，我解决了这个问题。

我为具有年份和数字属性的食物表单创建了一个模型我在该模型中定义了一个输入过滤器：

use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;

class Aliment implements InputFilterAwareInterface
{
    public $year;
    public $number;

    public function exchangeArray($data){
        $this->year             = (!empty($data['year']))?$data['year']:null;
        $this->number          = (!empty($data['number']))?$data['number']:null;
    }

    public function setInputFilter(InputFilterInterface $inputFilter)
    {
        throw new \Exception("Not used");
    }

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


            $inputFilter->add(array(
                'name'     => 'year',
                'required' => true,
                'filters'  => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    array(
                        'name' => 'Between',
                        'options' => array(
                            'min' => 1900, 
                            'max' => 3000
                        )
                    )
                ),
            ));

            $inputFilter->add(array(
                'name'     => 'number',
                'required' => true,
                'filters'  => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    array(
                        'name' => 'Between',
                        'options' => array(
                            'min' => 1, 
                            'max' => 10
                        )
                    )
                ),
            ));

            $this->inputFilter = $inputFilter;
        }

        return $this->inputFilter;
    }

}

在控制器的动作方法中，我能够将模型的InputFilter设置为窗体并瞧！它奏效了！

public function alimentAction(){
    $form = new AlimentForm();

    $request = $this->getRequest();
    if ($request->isPost()) {
        $aliment = new \Application\Model\Aliment;
        $form->setInputFilter($aliment->getInputFilter());
        $form->setData($request->getPost());


        if ($form->isValid()) {
            $aliment->exchangeArray($form->getData());
            $year           = $form->get('year')->getValue();
            return array(
                'result' => array(
                    //your result
                )
            );
        }
    }
    return array('form' => $form);
}

现在正确验证表单并返回相应的错误消息。

我希望，它可以帮助那些在验证方面遇到类似问题的人！
