我的Zend Form中有两个字段,我想应用验证规则,确保用户输入这两个字段之一.
$companyname = new Zend_Form_Element_Text('companyname');
$companyname->setLabel('Company Name');
$companyname->setDecorators($decors);
$this->addElement($companyname);
$companyother = new Zend_Form_Element_Text('companyother');
$companyother->setLabel('Company Other');
$companyother->setDecorators($decors);
$this->addElement($companyother);
我如何添加一个验证器来查看这两个字段？
请参阅此
page上的“注意：验证上下文”.Zend_Form将上下文传递给每个Zend_Form_Element :: isValid调用作为第二个参数.所以只需编写自己的分析上下文的验证器.

好的,我以为我自己拍了拍.它没有测试,也不是一切手段,但它会给你一个基本的想法.
class My_Validator_OneFieldShouldBePresent extend Zend_Validator_Abstract
{
const NOT_PRESENT = 'notPresent';
protected $_messageTemplates = array(
self::NOT_PRESENT => 'Field %field% is not present'
);
protected $_messageVariables = array(
'field' => '_field'
);
protected $_field;
protected $_listOfFields;
public function __construct( array $listOfFields )
{
$this->_listOfFields = $listOfFields;
}
public function isValid( $value,$context = null )
{
if( !is_array( $context ) )
{
$this->_error( self::NOT_PRESENT );
return false;
}
foreach( $this->_listOfFields as $field )
{
if( isset( $context[ $field ] ) )
{
return true;
}
}
$this->_field = $field;
$this->_error( self::NOT_PRESENT );
return false;
}
}
用法：
$oneOfTheseFieldsShouldBePresent = array( 'companyname','companyother' );
$companyname = new Zend_Form_Element_Text('companyname');
$companyname->setLabel('Company Name');
$companyname->setDecorators($decors);
$companyname->addValidator( new My_Validator_OneFieldShouldBePresent( $oneOfTheseFieldsShouldBePresent ) );
$this->addElement($companyname);
$companyother = new Zend_Form_Element_Text('companyother');
$companyother->setLabel('Company Other');
$companyother->setDecorators($decors);
$companyname->addValidator( new My_Validator_OneFieldShouldBePresent( $oneOfTheseFieldsShouldBePresent ) );
$this->addElement($companyother);
