Codeigniter错误日志不包括文件名

问题描述

我正在尝试从我的codeigniter web应用程序记录错误，我认为写入文件的消息被截断。我说这是因为每当屏幕上显示错误时，我得到错误发生的文件名，而当我检查错误日志时，它只会说，

I'm trying to log errors from my codeigniter web app and I think the messages that get written to file are getting truncated. I say this because whenever the error is displayed on screen I get the file name where the error occurred whereas when I check the error logs it only says,

有没有办法有错误日志返回错误的文件位置？

Is there a way to have the error log return the file location of the error?

推荐答案

不，目前没有内置的方式在CodeIgniter中执行此操作。

No, currently there isn't a built-in way to do this in CodeIgniter.

您可以做的是扩展核心 CI_Log 类，覆盖其 write_log（）方法，并使用 debug_backtrace（）获取相应的文件名，并将其添加到邮件中。

What you can do is to extend the core CI_Log class, override its write_log() method and use debug_backtrace() to get the appropriate file name and prepend it to the message.

// application/core/MY_Log.php
class MY_Log extends CI_Log {

    public function write_log($level, $msg)
    {
        foreach (debug_backtrace() as $call)
        {
            // Somehow find the appropriate call here ...
            if ( ! (/* condition to ignore error-handling calls */))
            {
                break;
            }

            $msg = '['.$call['file'].'] '.$msg;
            break;
        }

        return parent::write_log($level, $msg);
    }

}
