在components文件夹下面建立一个文件AutoTimestampBehavior.php，里面的内容为
<?php
class AutoTimestampBehavior extends CActiveRecordBehavior {
/**
* The field that stores the creation time
*/
public $createTime = 'creatTime';
/**
* The field that stores the modification time
*/
public $updateTime = 'updateTime';
public function beforeValidate($on) {
if ($this->Owner->isNewRecord)
$this->Owner->{$this->createTime} = new CDbExpression('NOW()');
else
$this->Owner->{$this->updateTime} = new CDbExpression('NOW()');
return true;
}
}
然后在model里面使用这个行为插件
public function behaviors(){
return array(
'AutoTimestampBehavior' => array(
'class' => 'application.components.AutoTimestampBehavior',
//You can optionally set the field name options here
)
);
}
其实在1.1 version之后，可以直接这样的了
public function behaviors(){
return array(
'CTimestampBehavior' => array(
'class' => 'zii.behaviors.CTimestampBehavior',
'createAttribute' => 'create_time_attribute',
'updateAttribute' => 'update_time_attribute',
)
);
}
如果model里面已经在使用public function behaviors()，记得要在前面加上parent::behaviors($on);
