笨不會記錄所有文件名錯誤日誌中

Question

我使用此配置登錄錯誤

$config['log_threshold'] = 1; 

問題是一些錯誤不包括像這樣的文件名，而其他錯誤，包括文件名

ERROR - 2017-04-27 14:20:16 --> Query error: You have an error in your SQL syntax; check the 
manual that corresponds to your MySQL server version for the right syntax to use near 
'ORDER BY `id` DESC' at line 4 - Invalid query: SELECT COUNT(*) AS `numrows` FROM `orders` 
WHERE `id` > ORDER BY `id` DESC 

ERROR - 2017-04-27 14:20:16 --> Severity: Error --> Call to a member function num_rows() on 
boolean /home/username/public_html/system/database/DB_query_builder.php 1391 

爲什麼會發生這種情況，以及如何解決它。我發現這個答案Codeigniter error log not including file name但是找不到'MY_Log.php'

Answer 1

我看到了答案：Codeigniter error log not including file name很清楚。按照這些步驟：

1. 創建MY_Log.php文件（記得MY_Log.php不MY_log.php或別的東西）在application/core文件夾中。

2. 複製下面的代碼片段，並粘貼到文件：

   類MY_Log擴展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); 
   } 
   

   }

3. 保存文件。完成！
