Hi there,

i have been beating my head against the wall trying to extend the Exception Class; then googling around showed your Website Post which is similar to what i want to do, eg. extending the show_404() (for starters) function so that it will file an entry into a database in addition to logging the error to a file.

Now, no matter what i do, MY_Exceptions.php errors out as soon i do something like $this->CI =& get_instance(); to get the Super Object. After some research, it seems that get_instance() is not available at the time my MY_Exceptions.php calls it. Now i have two questions:

1. How can i load either the Super Object, or at least some additional classes directly from within my extended Exception Class so i can for example access the Database Object?

2. If it does not work for me, how comes it works for you? I mean, sorry if this sounds weird, but for you the Code you posted in your Blog does actually work, and $ci =& get_instance(); does allow you to get to the Superobject, yes?

Thanks and regards!

Code:
&lt;?php if (!defined('BASEPATH')) exit('No direct script access allowed');

    class MY_Exceptions extends CI_Exceptions {

    function __construct(){

        parent::CI_Exceptions();

// Comment the below out and things will stop working

//$this->CI =& get_instance();

    }

    function show_404($page = '') {    

        $heading = "404 Page Not Found";

        $message = "The ppage you requested was not found.";

        log_message('error', '404 Page Not Found --&gt; '.$page);

// Here is where id like to extend so show_404() will also log to a database        

//$this->custom_logging->log_message('error','System','0',"Requested Page not found: $page");

        echo $this->show_error($heading, $message, 'error_404', 404);

        exit;

    }

    }
