I have a third party library which uses a external config file like this

application/library/api/API.php:

Code:

require_once "config.php";
error_log("Config var 1:" . $config_var); // Pure PHP Ok, CI Ok

class API {
    function __construct () {
        global $config_var;
        error_log("Config var 2:" . $config_var); // Pure PHP Ok, CI BLANK!!
    }
    function doSomething (param1, param2) {
        global $config_var_filename;
        global $config_var_number;
        $file = fopen($config_var_filename . '/' . param1, 'a+'); // Error
        fwrite($file, $config_var_number + param2); // More errors
        fclose($file); // And more errors
    }
}

I've setup a library stub this way

application/library/LibAPI:

Code:

include dirname(__FILE__) . '/api/API.php';

class LibAPI extends API {
    function __construct () {
        parent::__construct();
    }
}

Which I use in my controller like this

application/controllers/MyController:

Code:

class MyController extends CI_Controller {
    function __construct() {
        parent::__construct();
        $this->load->library('form_validation');
        $this->load->library('LibAPI');
        $this->load->helper(array('url', 'form'));
        ....
    }
    public function index () {
        $api = new LibAPI();
        $api->doSomething('.TXT', 1); // ERROR!!!
        ...
    }
    ...

The problem, as you can see in the included comments, is that under CI config parameters are not kept and, obviously, the API fails. I need to maintain the API code unchanged, so I cannot introduce CI specific code in it. What could I do?

Thank you.

Edo.

Codeigniter has own built in error log

http://www.codeigniter.com/user_guide/general/errors.html

http://www.codeigniter.com/user_guide/general/errors.html#log_message

And for writing file may be use codeigniter file helper

PHP Code:

$this->libapi->doSomething('.TXT', 1); 


instead of this:

PHP Code:

$api = new LibAPI();
$api->doSomething('.TXT', 1);

Thank you for responding.

The class constructor initializes some instance vars, so I have to instantiate it.

Cheers.
