无法加载请求的类：Session Codeigniter 3 [英] Unable to load the requested class: Session Codeigniter 3

问题描述

尝试在Codeigniter中加载会话库。似乎很明显是正确的，但actully不工作。
这是配置文件的一部分：

  $ config ['sess_driver'] ='database'; 
 $ config ['sess_cookie_name'] ='ci_session'; 
 $ config ['sess_expiration'] = 7200; 
 $ config ['sess_save_path'] = NULL; 
 $ config ['sess_match_ip'] = FALSE; 
 $ config ['sess_time_to_update'] = 300; 
  

此外，ncryption键变量已设置。此外，CI 3文档不能给我解决这个问题的方法。

我试图： / p>

1. 将'sess_save_path'变量设为'ci_sessions'


2. 检查文件夹权限


3. 检查表'ci_sessions'是否存在


4. 使用Autoloader类


5. 使用具有大写S的类名

---

这很奇怪，但配置说：

  / * 
 | -------------------------------------------------- ----------------- 
 |自动加载库
 | -------------------------------------------------- ----------------- 
 |这些是位于system / www文件夹
 |中的类或在您的应用程序/ www文件夹中。 
 | 
 |原型：
 | 
 | $ autoload ['www'] = array（'database'，'email'，'session'）; 
 | 
 |您还可以提供要分配的备用库名称
 |在控制器：
 | 
 | $ autoload ['www'] = array（'user_agent'=>'ua'）; 
 * / 
  

下面是自动加载器的代码：

  //载入www 
 if（isset（$ autoload ['www']）&& > 0）
 {
 //加载数据库驱动程序。 
 if（in_array（'database'，$ autoload ['www']））
 {
 $ this-> database 
 $ autoload ['www'] = array_diff（$ autoload ['www']，array（'database'））; 
} 
 
 //加载所有其他www 
 foreach（$ autoload ['www'] as $ item）
 {
 $ this-> library（$ item）; 
} 
} 
  

解决方案

您应该尝试的列表：

1. 确保您在autload.php中加载会话库： $ autoload ['libraries'] = array（'session'）;




2. 确保您的加密密钥设置为cofing .php： $ config ['encryption_key'] ='anything_here'




3. 被命名为 ci_sessions ，并且您的sess_save_path设置为该名称： $ config ['sess_save_path'] =ci_sessions




4. 如果您使用的是Unix / Linux，请务必使用大写字母加载库： $ autoload ['libraries'] = array （'Session'）;


5. 如果无效，请检查您是否从 http://www.codeigniter.com/download







Trying to load Session library in Codeigniter. It seems to be clearly right but actully don't work. Here's a part of config file:

$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;

As well, ncryption key variable has already set. Moreover, CI 3 documentation can't give me the way to solve this problem.

I've tried to:

1. Set 'sess_save_path' variable to 'ci_sessions'
2. Check folders permissions
3. Check if table 'ci_sessions' exists
4. Use Autoloader class
5. Use class name with capital S

---

It's strange a little, but config says:

 /*
| -------------------------------------------------------------------
|  Auto-load Libraries
| -------------------------------------------------------------------
| These are the classes located in the system/www folder
| or in your application/www folder.
|
| Prototype:
|
|   $autoload['www'] = array('database', 'email', 'session');
|
| You can also supply an alternative library name to be assigned
| in the controller:
|
|   $autoload['www'] = array('user_agent' => 'ua');
*/

And here's a code of autoloader:

// Load www
        if (isset($autoload['www']) && count($autoload['www']) > 0)
        {
            // Load the database driver.
            if (in_array('database', $autoload['www']))
            {
                $this->database();
                $autoload['www'] = array_diff($autoload['www'], array('database'));
            }

            // Load all other www
            foreach ($autoload['www'] as $item)
            {
                $this->library($item);
            }
        }

解决方案

Here's a list of what you should try:

1. Make sure you load the session library in autload.php: $autoload['libraries'] = array('session');

2. Make sure your encryption key is set in cofing.php: $config['encryption_key'] = 'anything_here'

3. Make sure your database table is named ci_sessions and your sess_save_path is set to that name: $config['sess_save_path'] = "ci_sessions"

4. If you are on Unix/Linux, make sure to load your library with capital letters: $autoload['libraries'] = array('Session');

5. If nothing works, check that you download and install the right CI3 files from http://www.codeigniter.com/download
