在codeigniter中动态设置我的配置变量后如何从其他控制器和模型访问它们？

问题描述：

I have updated my config variable in my model using:

$this->config->set_item('userid', $user_id);

if i echo it in the model i can see that it gets set.

But if i echo it in the controller or another model using:

echo $this->config->item('userid');

it shows the original value.

I need to store this config variable throughout the session but i do not want to use session variables.

我在模型中更新了我的配置变量： p>

  $ this-＆gt; config-＆gt; set_item（'userid'，$ user_id）; 
  code>  pre> 
 
 如果我在模型中回显它，我可以看到它得到它 但是如果我在控制器或其他模型中使用以下方式回显： p> 
 
 
  echo $ this-＆gt; config-＆gt;  item（'userid'）; 
  code>  pre> 
 
 它显示原始值。 p> 
 
 
我需要将此配置变量存储在整个 会话，但我不想使用会话变量。   p> 
  div>

答

that configurtation is only applicable on that model which you set it. If you want a global setting without using session.

you could create a core model on application/core and name it

MY_Model

so basically what MY_Model do is that it sets your config on all models that extends it.

class MY_Model Extends CI_Model
{
  protected $user_id;
  public function __construct()
  {
    parent::__construct();
   $this->config->set_item('userid', $this->user_id);
  }
}

then on your model that you want the settings to be applied, just extends your model. like

Model extends MY_Model
{

  public function test($id)
  {
    $this->user_id = $id;

   }
}

OR you could create a Core COntroller same as the above but substituting controller to model read more at http://ellislab.com/codeigniter/user-guide/general/core_classes.html

答

Try to initialize the config $this->ci = & get_instance(); and then set the value like $this->ci->config->set_item('userid', $user_id);

I have not tested this... but I assume it will work.
