I'm trying to pass vars from a config file to a library, but I can't get it to work. What I have so far (The config file is autoloaded):

In config

Code:
$config['path_imagemagick']    = '/usr/bin/convert ';

$config['path_tempdir']        = '/home/name/public_html/temp/';

$config['path_photosdir']    = '/home/name/public_html/photos/';

The library

Code:
class CI_ImgResizer_IM {

    var $CI;

    var $imagick         = $this->config->item('path_imagemagick');

    var $temppath         = $this->config->item('path_tempdir');

    var $newpath         = $this->config->item('path_photosdir');

    /**

     * Constructor

     *

     */    

    function CI_ImgResizer_IM()

    {    

        $this->CI =& get_instance();

        log_message('debug', "ImgResizer_IM Class Initialized");

    }

// the functions here

}

What am I missing or doing wrong??

You are missing the CI object in your variable declarations:

Code:
var $CI;

    var $imagick         = $this->CI->config->item('path_imagemagick');

    var $temppath         = $this->CI->config->item('path_tempdir');

    var $newpath         = $this->CI->config->item('path_photosdir');

I had already tried that (read it in another post), but it didn't work. Still doesn't...

Maybe I'm wrong, but isn't '$this->CI' only available AFTER the constructor?

I thought about that... if that is the case, well you obviously can't just use $this->config (unless you feel like writing a config class...

I'm not the most gangster OOP programmer, but what if you tried this:

Code:
var $CI;

    var $imagick;

    var $temppath;

    var $newpath;

    function __construct() {

        $this->CI =& get_instance();

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

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

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

    }

You will then just have to remember to refer to them as class variables.

Yaay, that works. Thanks!
