zf2验证表单:如何验证依赖字段？

Question

我有5个文本表格

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

与相对过滤器

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个表单中只有一个可以包含一个不同于0的值.然后有两个可能的错误.

太多了

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

没有号码

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

如何同时验证这多个字段？

Answer 1

你需要编写自己的Validator类才能这样做.isValid()新验证类的方法还会接收$context包含整个表单的值的方法.这样,您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
    }
}
