我的扩展 CodeIgniter 2.0.2 类看不到它的父类方法

这是我的第一个 OOP php 应用程序，我在这里有点困惑...

我创建了以下扩展 CI_Model 的类

class LXCoreModel extends CI_Model{

 function __construct() {
         parent::__construct();
}



public function elementExists($table,$row,$data){
     $result = $this->db->select('*')->from($table)->where($row, $data)->get()->result();
     if(empty($result))return false;
     return true;
}
}

，这是扩展上面的类的类：

class LXAccAdminModel extends LXCoreModel{

function __construct()
{
    parent::__construct();
}

function addAccountStatus($statusId=NULL, $username=NULL){
    if($statusId==NULL)$statusId = $this->input->post('accountStatusId');
    if($username==NULL)$username = $this->input->post('username');

    if(elementExists('accounts','username',$username))
            if(elementExists('statuses','id',$statusId))
            {$this->db->insert('accountstatus',array('statusid'=>$statusId,'username'=>$username)); return true;}
    return false;
}
}

两个类都在 Model 目录中，并且类 LXCoreModel是自动加载的（行 $autoload['model'] = array('LXCoreModel'); 存在于 autoload.php 文件中），但是，当我尝试运行我的代码时，我收到此错误：

致命错误：调用未定义函数 elementExists() 中 C:\wamp\www\CI_APP\application\models\LXAccAdminModel.php 第 25 行

感谢您的宝贵时间！ :)

This is my first OOP php app and I'm getting a little stumped here...

I created the following class that extends the CI_Model

class LXCoreModel extends CI_Model{

 function __construct() {
         parent::__construct();
}



public function elementExists($table,$row,$data){
     $result = $this->db->select('*')->from($table)->where($row, $data)->get()->result();
     if(empty($result))return false;
     return true;
}
}

And here is the class extending the class above:

class LXAccAdminModel extends LXCoreModel{

function __construct()
{
    parent::__construct();
}

function addAccountStatus($statusId=NULL, $username=NULL){
    if($statusId==NULL)$statusId = $this->input->post('accountStatusId');
    if($username==NULL)$username = $this->input->post('username');

    if(elementExists('accounts','username',$username))
            if(elementExists('statuses','id',$statusId))
            {$this->db->insert('accountstatus',array('statusid'=>$statusId,'username'=>$username)); return true;}
    return false;
}
}

Both classes are in the Model diretory, and the class LXCoreModel is autoloaded (the line $autoload['model'] = array('LXCoreModel'); exists in the autoload.php file) and yet, when I try to run my code I get this error:
