codeigniter autoload config file doesn't work in library

Question

I created a customized config file called config2 and autoload it in autoload.php. In my model, i just use $this->config->item('item_in_config2'), it works well. However, in my paypal library, i tried to use the same thing like this:

$this->PROXY_HOST = $this->config->item['paypal_proxy_host'];

an error occur: undefined property $config. Then i tried to add parent::__construct(); under library constructor, server error shows. Previously, i load the config2 manually and it worked well, but i really want to autoload it now. any ideas? thanks

I've run into this before. What are you using the second config file for? It's likely being loaded before something inside of it. — Devin Young

I think you have to call the CI instance in the library:

paypal library constructor:

$CI =& get_instance();

$proxy_host = $CI->config->item('paypal_proxy_host');

Libraries do not share the same application scope as controllers or models. You need to retrieve the CI super object as stormdrain said. See Utilizing CodeIgniter Resources within Your Library. If you want to use the $this syntax, you can do what models do, and use the __get() magic method to fetch the CI object. See /system/core/Model.php.
