Php CodeIgniter中的扩展异常

Php CodeIgniter中的扩展异常,php,codeigniter,Php,Codeigniter,我收到错误致命错误:在第233行的..\core\CodeIgniter.php中找不到类“CI_Controller” 我在application/core/My_Exception.php中创建了一个名为My_Exceptions的类 基本上,当用户从我的站点收到错误时,我希望收到电子邮件 <?php class My_Exceptions extends CI_Exceptions{ var $CI=""; function __construct(){

我收到错误致命错误:在第233行的..\core\CodeIgniter.php中找不到类“CI_Controller”

我在application/core/My_Exception.php中创建了一个名为My_Exceptions的类 基本上,当用户从我的站点收到错误时,我希望收到电子邮件

<?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('error-donotreply@YOURAPP.com', 'APP Error');
    $this->CI->email->to('youremail@example.org');
    $this->CI->email->subject('APP Error [severity: '.$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;
}
}

异常类在主CI_控制器之前加载

这意味着当发生错误时-您不能使用CI发送电子邮件,因为“$This->CI”不存在


你的选择是要么使用原生PHP发送电子邮件,要么我做什么;自动给自己发送前一天的错误日志(使用CRON作业)。这样,您可以每天检查一次所有错误。

我知道您已经接受了答案,但另一种方法是扩展CI日志类

<?php  if (!defined('BASEPATH')) exit('No direct script access allowed');
/**
 * MY_Log Class
 *
 * This library extends the native Log library.
 * It adds the function to have the log messages being emailed when they have been outputted to the log file.
 *
 * @package     CodeIgniter
 * @subpackage      Libraries
 * @category        Logging
 * @author      Johan Steen
 * @link        http://wpstorm.net/
 */
class MY_Log extends CI_Log {
    private $_reporting_email = 'test@me.com';
    private $_subject = 'CI Logger';

    /**
     * Constructor
     *
     * @access  public
     */
    function __construct() {
        parent::__construct();
    }

    /**
     * Write Log File

     * Calls the native write_log() method and then sends an email if a log message was generated.
     *

     * @param   string  the error message
     * @param   bool    whether the error is a native PHP error
     * @return  bool
     */
    function write_log($level = 'error', $msg, $php_error = FALSE) {
        $result = parent::write_log($level, $msg, $php_error);

        if ($result == TRUE && strtoupper($level) == 'ERROR') {
            $message = "An error occurred: \n\n";
            $message .= $level.' - '.date($this->_date_fmt). ' --> '.$msg."\n";

            $to = $this->_reporting_email;
            $subject = $this->_subject;
            $headers = 'From: Example Name <no-reply@example.com>' . "\r\n";
            $headers .= 'Content-type: text/plain; charset=utf-8\r\n';

            mail($to, $subject, $message, $headers);
        }
        return $result;
    }
}
?>


每生成一个404,就收到一封电子邮件,这似乎很疯狂,发电子邮件或手动查看每日日志更有意义(我可以理解不想创建cron作业)。本机
mail()
应该很好,当你只是给自己发电子邮件时这没什么大不了的。OP的代码被写入
show_404
函数中,但你可能是对的。在这种情况下,我要说的是,为每一个错误发送一封单独的电子邮件更加疯狂,因为会有更多的错误。除非你真的想让你的收件箱像疯了一样爆炸。。。单页加载可能会产生大量404(例如缺少图像),而不仅仅是404错误。我将添加到另一个错误处理程序。404很容易在我的本地主机上测试。谢谢,我要试试PHP本机。这是另一种选择。谢谢
