yii验证规则有问题，我为我的产品创建了一个带有优惠券代码的注册表单。当用户输入优惠券代码时，我想检查优惠券表中是否存在该值。当用户输入couponcode时，我希望我的验证规则有效，否则，如果用户不输入代码，这个验证规则就不应该有效，对于会员注册，我有会员模型，对于优惠券，我有优惠券模型，我在验证规则中使用此方法。
class MemberSignup extends CActiveRecord
{
public $couponcode;
public function rules(){
array('couponcode', 'isCouponCodeExist'),
}//end rules
public function isCouponCodeExist($attribute, $params)
{
$record = Coupon::model()->findByAttributes(array('couponcode' => $this->couponcode));
if($record === null){
$this->addError($attribute, 'Invalid Coupon');
return false;
}
return true;
}
} //class end
任何建议对我都有帮助

如果我理解正确，则不需要您的couponcode，并且只有当用户输入了couponcode时，您才希望验证该couponcode。
public function rules()
{
return array(
array('field1, field2, field3', 'required'),
array('couponcode', 'isCouponCodeExist'),
);
}
编辑：
在yii中，将执行模型中的所有验证方法，即使不需要验证的字段。即使您的字段couponcode不是必需的，验证方法isCouponCodeExist()也将始终执行。
这意味着我们必须在方法isCouponCodeExist()中编辑您的代码，以允许一个空的couponcode，有点像这样：
public function isCouponCodeExist($attribute, $params)
{
if(!empty($this->couponcode))
{
$record = Coupon::model()->findByAttributes(array('couponcode' => $this->couponcode));
if($record === null)
{
$this->addError($attribute, 'Invalid Coupon');
}
}
}
此外，在验证方法中不必返回true或false。你所需要做的就是在出现错误时添加一个错误。
