Yii模型验证规则

Question

yii验证规则存在问题，我创建了一个注册表单，其中包含我的产品的优惠券代码。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。 当用户输入优惠券时，我希望我的验证规则有效，否则，如果用户没有输入代码，则此验证规则不起作用，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suggesstion对我都有帮助

Answer 1

如果我理解正确，您的优惠券代码不是必需的，只有用户输入优惠券才能验证优惠券代码。

public function rules()
{
   return array(
        array('field1, field2, field3', 'required'),
        array('couponcode', 'isCouponCodeExist'),
    );
}

编辑：

在yii中，即使不需要验证的字段，也将执行模型中的所有验证方法。即使您的字段couponcode不是必需的，也始终会执行验证方法isCouponCodeExist()。

这意味着我们必须在方法isCouponCodeExist()中编辑您的代码以允许空的优惠券代码，如下所示：

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，您不必在验证方法中返回true或false。如果出现问题，您只需添加错误。
