How to autoload sitewide variables - El Forum - 07-10-2010
[eluser]Christophe28[/eluser]
Hi,
I wonder how to autoload variables to use sitewide like current online users, etc ...
I have read the userguide->autoloader but it seems this is only to autoload helpers, models, etc
Do I have to autoload a library with the online_users() function and include $data['online_users'] = $this->autoload_library->online_users(); in every conroller? There must be a better way?
Can somebody tell me how this is commonly done in codeigniter?
Thank you :-)
Christophe

You could always make your own library and load it when you need it (or simply load it site-wide in your autoload config file).
http://ellislab.com/codeigniter/user-guide/general/creating_libraries.html
You can keep variables, functions, or whatever else you need in there, because it is, effectively, just a class.

Hi,
I have searched the forum and userguide for 'my_controller' but can't find any useful information. There must be a simply way to autoload a file or class giving some variables for all pages in one time? Does somebody know how to do this?
I'm new in codeigniter and even oop ... I only have created some controllers, models, views and library, but saw myself creating the same variables over and over again for each page (controllerfunction) like 'online users' etc ...

MY_Controller is discussed in the user guide section "Creating core classes".
Alternative is to create a custom config file, define your variables there, and load it using $this->load->config() or via autoload. You can then use $this->config->item() in your controllers to fetch the variables.

Hi,
Thank you for your answer.
But creating a config file, autoloading it would be the same as creating a library and autoloading it, not? I could use the variables in the all different controllers, but my goal is to autoload a file or class, and use the variables directly in the view like for example using {memory_usage} I'd like to create somthing like this {online_users} ...

What you could do is this:
Extend the controller class and have your own _output method. Something like this:
Code:
class MY_Controller extends Controller
{
function MY_Controller()
{
parent::Controller();
}
function _output($output)
{
$this->load->model('Some_model');
echo str_replace('{online_users}', $this->Some_model->get_online_users(), $output);
}
}All your controllers then have to extend MY_Controller instead of Controller. Check the User Guide for more into on this.

Mh..should work as my example more or less directly taken from the user guide.
I'll give it a try myself..maybe I can get it to work.
