【求助】权限管理、节点管理。 提示错误！
CI框架以下是相关代码段
NodeService.php
/**
* 获取节点信息
*/
public function getNodes()
{
$nodes = $this->Adminnode_model->queryAllBySort("admin_node",array("weight"=>"desc"));
$this->tidyNode($nodes->result(),$data);
return $data;
}
/**
* 将读取出来的所有节点整理
* @param array $nodelist 节点数组
* @param arrat $data 空数组，存放整理后的数据
* @param int $pid父id
* @param int $forlevel 递归深度
*/
private function tidyNode(&$nodelist,&$data=0,$pid=0,$forlevel=0){
$forlevel++;
foreach($nodelist as $node){
if($node->pid == $pid){
$node->forlevel = $forlevel;
$data[] = $node ;
$this->tidyNode($nodelist,$data,$node->id,$forlevel);
}
}
}
AdminNode.php
/**
* 打开节点管理首页
*/
public function index()
{
$nodes=$this->NodeService->getNodes();
$this->by_smarty->assign('nodes',$nodes);
$this->by_smarty->view('admin/auth/node');
}

$this 是呼叫當前 class 內的所有 function
CI 似乎沒有提供 Controller 間互相呼叫
你可以考慮寫在 Model
