如何在 Zend Framework 2 中验证空输入

Question

我正在 ZF2 中填写注册表，但我不知道如何验证。验证似乎不起作用。

我正在添加验证器数组，但它无论如何都不起作用。我不知道我该如何解决。

这是我的控制器代码：

namespace Application\Controller;

use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Application\Form\Formularios;
use Zend\Db\Adapter\Adapter;
use Application\Modelo\Entity\Usuarios;

class FormularioController extends AbstractActionController
{
   public $dbAdapter;
    public function indexAction()
    {
        return new ViewModel();
    }
    public function registroAction()
    {

        if($this->getRequest()->isPost())
        {
            $this->dbAdapter=$this->getServiceLocator()->get('Zend\Db\Adapter');
            $u=new Usuarios($this->dbAdapter);
            //echo "se recibió el post";exit;
            $data = $this->request->getPost();


            $u->addUsuario($data);
             return $this->redirect()->toUrl($this->getRequest()->getBaseUrl().'/application/formulario/registro/1');

        }else
        {
            //zona del formulario
                                 $form=new Formularios("form");

             $id = (int) $this->params()->fromRoute('id', 0);
             $valores=array
            (
                "titulo"=>"Registro de Usuario",
                "form"=>$form,
                'url'=>$this->getRequest()->getBaseUrl(),
                'id'=>$id
            );
            return new ViewModel($valores);
        }

    }

}

这是我的带有验证器的表单代码

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

        $this->add(array(
            'name' => 'name',
            'required'    => true,
         'allow_empty' => false,
            'options' => array(
                'label' => 'Nombre Completo',
            ),
            'attributes' => array(
                'type' => 'text',
                'class' => 'input'
            ),
            'filters' => [ ['name' => 'StringTrim'], ],

            'validators' => array(
             array(
            'name' => 'NotEmpty',
            'options' => array(
                'messages' => array(
                    \Zend\Validator\NotEmpty::IS_EMPTY => 'Ingrese Nombres.',
                ))))
        ));

         $this->add(array(
            'name' => 'lastname',
            'required' => true,
            'options' => array(
                'label' => 'Apellido',
            ),
            'attributes' => array(
                'type' => 'text',
                'class' => 'input'
            ),
            'validators' => array(
        array(
            'name' => 'NotEmpty',
            'options' => array(
                'messages' => array(
                    \Zend\Validator\NotEmpty::IS_EMPTY => 'Ingrese Apellidos.',
                ))))
        ));

第一个问题。

$data = $this->request->getPost(); 应该是$data = $this->getRequest()->getPost();

第二个问题是当您在视图中构建表单时直接调用验证器，这是错误的。正确的做法是通过 inputFilter。现在，有很多方法可以做到这一点，例如：使用或不使用从模型中调用的工厂，或者通过带有表单元素管理器的 for 类

我将向您展示工厂的示范方式，因为它对新手来说更容易。

namespace MyModule\Model;

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

class MyModel implements InputFilterAwareInterface
{
    /**
     * @var null $_inputFilter inputFilter
     */
    private $_inputFilter = null;

   // some more code like exhnageArray get/set method

    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([
                    'name'     => 'id',
                    'required' => false,
                    'filters'  => [
                        ['name' => 'Int'],
                    ],
                ])
            );
            $inputFilter->add(
                $factory->createInput([
                    "name"=>"title",
                    "required" => true,
                    'filters' => [
                        ['name' => 'StripTags'],
                        ['name' => 'StringTrim'],
                    ],
                    'validators' => [
                        ['name' => 'NotEmpty'],
                        [
                            'name'    => 'StringLength',
                            'options' => [
                                'encoding' => 'UTF-8',
                                'min' => 1,
                                'max' => 200,
                            ],
                        ],
                    ],
                ])
            );
            $inputFilter->add(
                $factory->createInput([
                    "name"=>"text",
                    "required" => true,
                    'filters' => [
                        ['name' => 'StripTags'],
                        ['name' => 'StringTrim'],
                    ],
                    'validators' => [
                        ['name' => 'NotEmpty'],
                        [
                            'name'    => 'StringLength',
                            'options' => [
                                'encoding' => 'UTF-8',
                                'min' => 1,
                            ],
                        ],
                    ],
                ])
            );
            $this->inputFilter = $inputFilter;
        }
        return $this->inputFilter;
    }

    }

第三个问题。永远不要在控制器中使用 serviceManager。这是一个非常非常非常糟糕的做法。而是使用工厂。
