[answered] is this the correct way to get info from config file ? - El Forum - 06-02-2009

I am creating my own library, but I have a couple of doubts, the most important is how can I retrieve the values (inside the library to display them) from the config file.

I did something like this:

I have my config file "mylibrary.php" and of course my library "Mylibrary.php"

My library:

Code:
class Mylibrary {

var $title;

    function Mylibrary()

    {

        $this->CI=& get_instance();

        $this->title = $this->CI->config->item('title');

    }

    function showMessage(){

        echo $this->title;        

    }

 }

My config file just have this:

Code:
config['title']='My title';

In a controller a load the library and call the funcion "showMessage"

and it works, my doubt it's if it's correct use this:

Code:
$this->CI=& get_instance();

$this->title = $this->CI->config->item('title');

To set values from a config file and display them (or use them for any operation).

Thanks.

p.s. I saw this in the FreakAuth library just if you are wondering.

I think you should load the configuration file first

Code:
$this->CI =& get_instance();

$this->CI->load->config('mylibrary');

$this->title = $this->CI->config->item('title');

config_item('item_key')

The Config library is the preferred way of accessing configuration information, however config_item() can be used to retrieve single keys. See Config library documentation for more information.

I believe it is. Of course the config file should have been loaded already.

I'm sorry y forgot to say it, I've already loaded the config using de /config/autoload.php

onfig_item(‘item_key’)

Code:
$this->CI =& get_instance();

You are accessing the Codeigniter Object by storing it(by reference) in the $this->CI variable

Code:
$this->CI->load->config('mylibrary');

Using the loader class you load the mylibrary.php configuration file

Thank you, I guess I got it, but still get confused because it use a lot of "levels" or the symbol "->", I mean, I understand the "$controller->function()" notation but when I see more "->" I just get lost, thank you again.
