以下是model 代碼

<?php

 */

namespace frontend\models;

use yii\base\Model;
use yii;
use db;
class Rbac extends Model
{
        public $role;
        public $power;
        public $user;
        public function rules(){
            return[

            ];
        }
        public function attributeLabels()
        {
          return[
              ‘role‘=>‘角色‘,
              ‘power‘=>‘權限‘,
              ‘user‘=>‘用戶‘
          ];
        }
        static public function getrole($tablename){
            $sql = "select name from $tablename where TYPE = 1";
            $data = Yii::$app->db->createCommand($sql)->queryAll();
            return $data;
        }
        static public function getpower($tablename){
            $sql = "select name from $tablename where TYPE = 2";
            $data = Yii::$app->db->createCommand($sql)->queryAll();
            return $data;
        }
        static public function rolepower($role,$power){
            $arr = array();
            foreach($role as $value) {
                foreach ($power as $v) {
                    $arr[] = array($value, $v);
                }
            }
            return $arr;
        }
        static public function getuser($tablename){

}

view 層代碼就沒必要寫了吧
