Question

我的zend框架2中的验证器无效。即使你可以看到required =＆gt; true工作，如果我传递一个空字符串，则显示错误。但最小和最大长度验证不起作用，$ form-＆gt; 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

我想你错过了documentation tutorial中的某些内容。你的代码错了。

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应位于options数组中。

嗯，上面的代码是在文档中，而不是工作。我不知道原因，但我找到了解决方案。对于验证器，请替换

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

                )

            )

带

'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;
    }

}
