本文实例讲述了yii实现model添加默认值的方法。分享给大家供大家参考,具体如下:
yii model 继承自CActiveRecord
有些字段可能不会出现在表单中,而需要在程序中加入。如订单编号,时间戳,操作的user_id等等。
以下二种方法:
1、在rules()方法中设定:
public function rules(){ // NOTE: you should only define rules for those attributes that // will receive user inputs. return array( array("start, end", "required"), array("user_id", "numerical", "integerOnly"=>true), array("timestamp","default","value"=>date("Y-m-d H:i:s")), // The following rule is used by search(). // Please remove those attributes that should not be searched. array("id, start, end, user_id, timestamp", "safe", "on"=>"search"), );}
2、在beforeSave()方法中设定:
function beforeSave(){ $this->user_id = Yii::app()->user->id; return true;}
需要注意的是,beforeSave()方法需要return true,否则不会保存。
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
