這是很簡單的,真的。
我有幾個Zend_Validate類型的驗證器與Doctrine ORM交談,所以我有一個抽象類,他們下降。
這裏的抽象類:
<?php
namespace TimDev\Validate\Doctrine;
abstract class AbstractValidator extends \Zend_Validate_Abstract{
/**
* @var Doctrine\ORM\EntityManager
*/
private $_em;
public function __construct(\Doctrine\ORM\EntityManager $em){
$this->_em = $em;
}
public function em(){
return $this->_em;
}
}
這裏是我的NoEntityExists驗證:
<?php
namespace TimDev\Validate\Doctrine;
class NoEntityExists extends AbstractValidator{
private $_ec = null;
private $_property = null;
private $_exclude = null;
const ERROR_ENTITY_EXISTS = 1;
protected $_messageTemplates = array(
self::ERROR_ENTITY_EXISTS => 'Another record already contains %value%'
);
public function __construct($opts){
$this->_ec = $opts['class'];
$this->_property = $opts['property'];
$this->_exclude = $opts['exclude'];
parent::__construct($opts['entityManager']);
}
public function getQuery(){
$qb = $this->em()->createQueryBuilder();
$qb->select('o')
->from($this->_ec,'o')
->where('o.' . $this->_property .'=:value');
if ($this->_exclude !== null){
if (is_array($this->_exclude)){
foreach($this->_exclude as $k=>$ex){
$qb->andWhere('o.' . $ex['property'] .' != :value'.$k);
$qb->setParameter('value'.$k,$ex['value'] ? $ex['value'] : '');
}
}
}
$query = $qb->getQuery();
return $query;
}
public function isValid($value){
$valid = true;
$this->_setValue($value);
$query = $this->getQuery();
$query->setParameter("value", $value);
$result = $query->execute();
if (count($result)){
$valid = false;
$this->_error(self::ERROR_ENTITY_EXISTS);
}
return $valid;
}
}
用於Zend_Form的(其中有像上面的抽象類的EM()方法)的情況下:
/**
* Overrides superclass method to add just-in-time validation for NoEntityExists-type validators that
* rely on knowing the id of the entity in question.
* @param type $data
* @return type
*/
public function isValid($data) {
$unameUnique = new NoEntityExists(
array('entityManager' => $this->em(),
'class' => 'PMS\Entity\User',
'property' => 'username',
'exclude' => array(
array('property' => 'id', 'value' => $this->getValue('id'))
)
)
);
$unameUnique->setMessage('Another user already has username "%value%"', NoEntityExists::ERROR_ENTITY_EXISTS);
$this->getElement('username')->addValidator($unameUnique);
return parent::isValid($data);
}
到目前爲止,感謝兩位響應者。研究你的代碼 - 我在ZF中使用插件/自定義類還是很新的。一旦我找到工作,將會選擇一個答案。 – cantera
