php(Yii)的增删改查之改

public function actionIndex ()
    {
        parent::_acl(); 
        self::_updateData($_POST['Config']);
        $this->render('index', array ('config' => self::loadData() ));
    
    }

　　

1.操作前判断权限：

protected function _acl ($action = false, $params = array('ajax'=>false, 'append'=>',default_index,default_home'))
    {
        $actionFormat = empty($action) ? strtolower($this->id . '_' . $this->action->id) : strtolower($action);
        $permission = self::_sessionGet('_adminiPermission');
        if ($permission != 'administrator') {
            $adminiGroup = self::_sessionGet('_adminiGroupId');
            $aclDb = AdminGroup::model()->find('id=:id', array ('id' => $adminiGroup ));
            if (! in_array($actionFormat, explode(',', strtolower($aclDb->acl) . $params['append']))) {
                if($params['ajax'] == false){
                    XUtils::message('error', '当前角色组无权限进行此操作，请联系管理员授权', $this->createUrl('index'), 20);
                }else{
                    $var['state'] = 'error';
                    $var['message'] = '当前角色组无权限进行此操作，请联系管理员授权';
                    exit(CJSON::encode($var));
                }
            }
        }
    }

2.修改提交页面（还有刷新缓存）：

 private function _updateData ($data, $scope = 'base')
    {
        if (XUtils::method() == 'POST') {
            foreach ((array) $data as $key => $row) {
                $connection = Yii::app()->db->createCommand("REPLACE INTO {{config}}(`scope`, `variable`, `value`) VALUES('$scope','$key', '$row') ")->execute();
            }
            XXcache::refresh('_config', 3600);
            parent::_adminiLogger(array (
			'catalog' => 'update' ,
			'intro' => '更新系统配置，模块：' . $this->action->id 
			)); 
            XUtils::message('success', '更新完成', $this->createUrl($this->action->id));
        }
    
    }

　3.将数据渲染到修改页面（取数据）：

public function loadData ()
    {
        $model = Config::model()->findAll();
        foreach ($model as $key => $row) {
            $config[$row['variable']] = $row['value'];
        }
        return $config;
    
    }
