如何加ID生成? [ 新手入门 ]

已解决，多谢舰长关注，呵呵

第11行，改成 static function getHost($coumputer_name, $ip)

照样做了，还是显示：

PHP Error

Non-static method NetAddress::getHost() should not be called statically, assuming $this from incompatible context

\protected\components\Guid.php(10)

function getGuid($coumputer_name, $ip){  
10  $address = NetAddress::getHost($coumputer_name, $ip);
11  $this->valueBeforeMD5=$address->toString().':'.System::currentTimeMillis().':'.Random::nextLong();  
12  $this->valueAfterMD5 = md5($this->valueBeforeMD5);  
}

在models/User.php下添加如下代码：

/*
* 生成GUID
*/
protected function beforeSave(){
  $computer_name = $_SERVER["SERVER_NAME"];  
  $ip = $_SERVER["SERVER_ADDR"];  
  $guid = new Guid($computer_name, $ip); 
  $id= $guid->toString(); 
  $this->id = $id;  
}

表单提交不成功，没有插入数据库数据，也无错误提示信息。请舰长明察，多谢
