zf2验证表:如何验证依赖字段？

Question

我有5个文本表单

$number1 = new Text('number-1');
$number2 = new Text('number-2');
$number3 = new Text('number-3');
....

使用相对过滤器

foreach(...)
   $input = new Input($elementName);
   $validator = new ValidatorChain();
   $validator->addByName('Int')
       ->addByName('Between', array(
          'min'=>0,
          'max'=>$this->maxAllowedTicket,
          'inclusive'=>true));
   $filter = new FilterChain();
   $filter->attachByName('Int');

   $input->setValidatorChain($validator);
   $input->setFilterChain($filter);

我希望这3种形式中只有一种可以包含不同于0的值。然后有两个可能的错误。

数字太多

 $data['number1'] = 5;
 $data['number2'] = 5;
 $data['number3'] = 0;
 $data['number4'] = 5;
 $data['number5'] = 0;

没有数字

 $data['number1'] = 0;
 $data['number2'] = 0;
 $data['number3'] = 0;
 $data['number4'] = 0;
 $data['number5'] = 0;

如何同时验证此多个字段？

Answer 1

为此，您需要编写自己的Validator类。新验证类的isValid()方法还接收包含整个表单的值的$context。这样，您就可以根据其他字段验证每个字段的值。

namespace My\Validator;
use Zend\Validator\AbstractValidator;

class CustomValidator extends AbstractValidator
{
    public function isValid($value, $context = null)
    {
        // put your logic here and call
        // $this->error(); if required
    }
}

Answer 2

使用回调验证器创建您自己的解决方案。

示例如下：http://packages.zendframework.com/docs/latest/manual/en/modules/zend.validator.set.html#callback
