验证器在 Zend Framework 2 中不起作用

Question

我的 zend 框架 2 中的验证器不工作。即使您可以看到 required=>true 有效，并且如果我传递一个空字符串，也会向我显示错误。但是最小和最大长度验证不起作用，$form->isValid() 只返回 true。任何帮助将不胜感激。 我在 Zend 网站上关注本教程。 http://framework.zend.com/manual/2.3/en/user-guide/forms-and-actions.html

    public $username;
    public $password;

    protected $inputFilter;

    public function exchangeArray($data){
        $this->username = isset($data['username']) ? $data['username'] : null;
        $this->password = isset($data['password']) ? $data['password'] : null;
    }

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

我认为您错过了documentation tutorial 中的某些内容。你的代码是错误的。

你有：

'validators' => array(
                array('name' => 'StringLength',
                    'encoding' => 'UTF-8',
                    'min' => 5,
                    'max' => 35

                )

            )

你应该有这个：

'validators' => array (
                    array (
                            'name' => 'StringLength',
                            'options' => array (//<-----options array here
                                    'encoding' => 'UTF-8',
                                    'min' => 1,
                                    'max' => 100 
                            ) 
                    ) 
            ) 

min、max 和 encoding 应该在 options 数组中。

Answer 2

好吧，上面的代码在文档中并且不起作用。我不知道原因，但我找到了解决方案。对于验证器，替换

'validators' => array(
                array('name' => 'StringLength',
                    'encoding' => 'UTF-8',
                    'min' => 5

                )

            )

与

'validators' => array(
                new StringLength(
                    array(
                        'encoding' => 'UTF-8',
                        'min' => 5
                    )
                ),

            ),

这是完整的代码。

namespace AdminAuthentication\Model;

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

class Login implements InputFilterAwareInterface
{
    public $username;
    public $password;

    protected $inputFilter;

    public function exchangeArray($data)
    {
        $this->username = isset($data['username']) ? $data['username'] : null;
        $this->password = isset($data['password']) ? $data['password'] : null;
    }

    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' => 'username',
                'required' => true,
                'filters' => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    new StringLength(
                        array(
                            'encoding' => 'UTF-8',
                            'min' => 5,
                            'max' => 35

                        )
                    ),

                ),
            )));

            $inputFilter->add($factory->createInput(array(
                'name' => 'password',
                'required' => true,
                'filters' => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    new StringLength(
                        array(
                            'encoding' => 'UTF-8',
                            'min' => 5
                        )
                    ),

                ),
            )));

            $this->inputFilter = $inputFilter;

        }
        return $this->inputFilter;
    }

}
