自定義codeigniter的日誌文件名log_message（）

Question

有沒有辦法自定義CodeIgniter 2.1.0中由log_message()生成的日誌的文件名？默認情況下，它的文件名是根據當前日期生成的。

Answer 1

log_message()功能是通用系統功能。它使用Log::write_log()方法記錄錯誤。它不擅長破解核心文件。所以你可以擴展日誌庫並覆蓋write_log()函數。

如果你還沒有擴展你的Log類。創建文件application/libraries/MY_Log.php

class MY_Log extends CI_Log { 

    function MY_Log() 
    { 
     parent::__construct(); 

     $this->ci =& get_instance(); 
    } 

    public function write_log() { //here overriding 
     if ($this->_enabled === FALSE) 
     { 
     return FALSE; 
     } 

     $level = strtoupper($level); 

     if (! isset($this->_levels[$level]) OR 
     ($this->_levels[$level] > $this->_threshold)) 
     { 
     return FALSE; 
     } 

     /* HERE YOUR LOG FILENAME YOU CAN CHANGE ITS NAME */ 
     $filepath = $this->_log_path.'log-'.date('Y-m-d').EXT; 
     $message = ''; 

     if (! file_exists($filepath)) 
     { 
     $message .= "<"."?php if (! defined('BASEPATH')) 
     exit('No direct script access allowed'); ?".">\n\n"; 
     } 

     if (! $fp = @fopen($filepath, FOPEN_WRITE_CREATE)) 
     { 
     return FALSE; 
     } 

     $message .= $level.' '.(($level == 'INFO') ? ' -' : '-').' '; 
     $message .= date($this->_date_fmt). ' --> '.$msg."\n"; 

     flock($fp, LOCK_EX); 
     fwrite($fp, $message); 
     flock($fp, LOCK_UN); 
     fclose($fp); 

     @chmod($filepath, FILE_WRITE_MODE); 
     return TRUE; 
    } 
} 

比log_message()功能將作爲您的願望

隨着CI 2.1.3使工作使用此代碼。在庫文件夾中創建MY_Log.php。不是確切的什麼需要的OP，但每個人都會明白如何modyfy :)
