Zend Framework 2 仅显示所需的自定义验证错误消息

Question

我有一个必填的 ISBN 字段，我想为其更改一般错误消息。我已经设置了自定义错误消息并且它们有效。过滤器是模型 fieldSet 的 getInputFilterSpecification() 函数的一部分，它可以正确验证和显示自定义错误消息：

use Zend\Form\Element;
use Zend\Form\Fieldset;
use Zend\Validator;
use Zend\InputFilter\InputFilterProviderInterface;
use Zend\Stdlib\Hydrator\ClassMethods as ClassMethodsHydrator;

class BookItemFieldset extends Fieldset implements InputFilterProviderInterface
{
    public $Types;

    public function __construct($itemName, $Types)
    {

        parent::__construct($itemName, $Types);

        $this->Types = $Types;

        // .. Other fields

        $bookISBN = new Element\Number('bookISBN');
        $bookISBN->setLabel('Book ISBN ')
            ->setAttribute('id', 'bookISBN');

        // .. more fields

        $this->add($bookISBN);
    }

    public function getInputFilterSpecification()
    {
        return array(

            'bookISBN' => array(
                'required' => true,
              'validators' => array(
                  new Validator\NotEmpty(array(
                          'setMessage'=> 'ISBN is Required'
                      )
                  ),
                  new Validator\Isbn(array(
                      'setMessage'=> 'ISBN is Invalid'
                  )),

              )
            ),
           //... more input filters

        );

    }
}

但是当该字段留空时。 "ISBN is Invalid" 和 "ISBN is required" 消息都会出现。

有没有办法在该字段留空时只显示所需的错误消息？

类似于以下内容：

    'bookISBN' => array(
        'required' => array(
            'required' => true,
            'setMessage' => 'ISBN is required' // Only this shows if field is empty
        ),
        'validators' => array(
            new Validator\Isbn(array(
                'setMessage'=> 'ISBN is Invalid' // only this shows if the input is invalid
            )),

        )
    ),

谢谢。

您需要通过将其设置为 true 来打破链条，默认情况下 Zend 将其设置为 false。你能试试看下面的代码是否有效吗？

public function getInputFilterSpecification()
    {
        return array(

            'bookISBN' => array(
                'required' => true,
              'validators' => array(
                  array(
                     'name' => 'not_empty',
                     'break_chain_on_failure' => true,
                     'options' => array(
                         'messages' => array(
                              \Zend\Validator\NotEmpty::IS_EMPTY => 'ISBN is required',
                         ),
                     ),
                  ),
                  new Validator\Isbn(array(
                      'setMessage'=> 'ISBN is Invalid'
                  )),

              )
            ),
           //... more input filters

        );

    }

或者可能是 'NotEmpty'。我无法测试它。

public function getInputFilterSpecification()
    {
        return array(

            'bookISBN' => array(
                'required' => true,
              'validators' => array(
                  array(
                     'name' => 'NotEmpty',
                     'break_chain_on_failure' => true,
                  ),
                  new Validator\Isbn(array(
                      'setMessage'=> 'ISBN is Invalid'
                  )),

              )
            ),
           //... more input filters

        );

    }
