本文介绍了simogeo filemanager +用户目录的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

你好,我喜欢simogeo的filemanager。



Filemanager忽略。 $ _SESSION ['userfoldername']。'/'或在我的例子中。 $ _SESSION ['authname']。'/'



使用$ _SESSION文件管理器会创建一个用户目录..但是它可以工作



来自simogeo的支持并不是那么好。他关上了机票,说出了我唯一的问题。但是我找不到问题。



user.config.php

Hello, ive Problems with filemanager from simogeo.

The Filemanager ignores . $_SESSION['userfoldername'].'/' or in my example . $_SESSION['authname'].'/'

With with $_SESSION the filemanager would create an userdirectory.. but it dosend work

The support from simogeo was not so good. he closed the ticket and say its only my problem. But i cant find the Problem.

user.config.php

//session_start ();

function auth() {
session_name  ('sid');
    session_start();
    if(isset($_SESSION['authright']) )
    {
        if($_SESSION['authright'] <= -3)
        {
            return true;
        }
    }
    return false;
}

$folderPath = 'include/images/uploads/userfiles/' . $_SESSION['authname'].'/';
$fm = new Filemanager();
$fm->setFileRoot($folderPath, true);
