Yii中对CUniqueValidator使用附加字段结合判断

1.在AR的rules中的定义

public function rules()
{
    return array(
        array('name', 'unique', 'criteria' => array('condition' => "`user_site_id`=>'{$this->user_site_id}'")),
    );
}

2.自定义验证规则

public function rules()
{
    return array(
        array('name', 'validateSiteUnique');
    );
}
 
public function validateSiteUnique($attribute, $param)
{
    if (!$this->hasErrors()) {
        $siteUniqueCriteria = new CDbCriteria();
        $siteUniqueCriteria->addCondition("`user_site_id`='{$this->user_site_id}'");
        $validator = new CUniqueValidator();
        $validator->attributes = array($attribute);
        $validator->criteria = $siteUniqueCriteria;
        $validator->validate($this);
    }
}
