Question

public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('entity_category_id, entity_id', 'required'),
        array('preferred','boolean'),

        // unique with condition
        array('email','unique',
            'criteria'=>array(
                'condition' => 'gmail= :gmail OR email= :email',
                'params' => array(':email' => $this->email, ':gmail' => $this->email)
            ),
        ),

        // The following rule is used by search().
        // Please remove those attributes that should not be searched.
        array('id, entity_category_id, entity_id', 'safe', 'on'=>'search'),
    );
}

以上唯一查询将WHERE子句运行为（gmail =＆＃39; abc＆＃39; OR email =＆＃39; abc＆＃39;）AND（email =＆＃39; abc）但我不想要和条件，我只想要（gmail =＆＃39; abc＆＃39;或电子邮件=＆＃39; abc＆＃39;）在where子句中

将标准添加到原始条件是正常的。来自Yii API：

条件：其他查询条件。数组或CDbCriteria。这将与检查相应表列
中是否存在属性值的条件相结合

我认为解决问题的最简单方法是在模型类中创建自己的验证器：

public function EmailValidator($attribute,$params)
{
    $criteria = new CDbCriteria;
    $criteria->condition = 'gmail= :gmail OR email= :email';
    $criteria->params = array(':email' => $this->email, ':gmail' => $this->email);
    $result = $this->findAll($criteria);
    if(!empty($result)) {
        $this->addError($attribute, 'Email already exists!');
    }
    return;
}

并使用rules方法调用它：

public function rules()
{
    return array(
       //Other rules
       array('email', 'EmailValidator'),
    );
}

Yii：如何改变独特的标准？
