Question

I got error Fatal error: Class ‘CI_Controller’ not found in ….\core\CodeIgniter.php on line 233

I create a class called My_Exceptions in application/core/My_Exception.php
Basically, I want to get email when user gets error from my site.

<?php
class My_Exceptions extends CI_Exceptions{
    var $CI="";
    function __construct(){
        parent::__construct();
        $this->CI =& get_instance();
    }
    function show_404($page = '', $log_error = TRUE)
{
    $heading = "404 Page My Not Found";
    $message = "The page you requested was not found.";

    // By default we log this, but allow a dev to skip it
    if ($log_error)
    {
        log_message('error', '404 Page Not Found --> '.$page);
    }

    //Email to Developer
    $this->CI->load->library('email');
    $uri = $this->CI->uri->uri_string();  
    $this->CI->email->from('[e-mail]', 'APP Error');
    $this->CI->email->to('[e-mail]');
    $this->CI->email->subject('APP Error [severity: '.$severity.']');
    $this->CI->email->message("Page not Found. From URL: ".$uri);
    $this->CI->email->send();

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

Please help !!!

The Exceptions class is loaded BEFORE the main CI_Controller.

This means when an error occurs – you cannot use CI to send an email, because “$this->CI” does not exist.

Your options are to either use the native PHP to send the email, or what I do; automatically email yourself the error logs from the day before (using a CRON job). That way you can review all the errors once a day.
