php – CodeIgniter Error Log Info + Errors

Posted by: admin July 12, 2020 Leave a comment

Questions:

IS there a way to save in the log, Info + Errors without debug?
Howcome debug level apears with info?
If i want to log info “Account id 4345 was deleted by Admin”, why do i need to see all of these:

How to&Answers:

From CodeIgniter’s docs:

log_message('info', 'The purpose of some variable is to provide some value.');

Informational Messages. These are the lowest priority messages, simply giving information regarding some process. CodeIgniter doesn’t natively generate any info messages but you may want to in your application.

Note: In order for the log file to actually be written, the “logs” folder must be writable. In addition, you must set the “threshold” for logging. You might, for example, only want error messages to be logged, and not the other two types. If you set it to zero logging will be disabled.

Answer:

You will not face the issue in codeigniter 2

$config['log_threshold'] = array(1, 3);

in config/config.php

and

log_message('info', 'The purpose of some variable is to provide some value.');

where you want to log something will only print that message to the log file, no excess debug code.

BUT

In codeIgniter 3, Many system core files have

log_message(‘info’, ******************);

Like

log_message('info', 'Config Class Initialized');
log_message('info', 'Controller Class Initialized');
log_message('info', 'Hooks Class Initialized');
............

That’s why when

$config['log_threshold'] = array(1, 3);

or

$config['log_threshold'] = array(3);

or

$config['log_threshold'] = 3;

then all the undesired log messages are appearing in log file.

So, the one way is to resolve this is to extend all core files and change

log_message('info'

to

log_message('debug' 

or creating a new thresold, like

in config/config.php

$config['log_threshold'] = array(1, 5);

in core/MY_Log.php

protected $_levels = array('ERROR' => '1', 'DEBUG' => '2', 'INFO' => '3', 'ALL' => '4', 'USER_INFO' => '5');

Full core/MY_Log.php file

class MY_Log extends CI_Log
{

    protected $_log_path;
    protected $_threshold = 1;
    protected $_date_fmt = 'Y-m-d H:i:s';
    protected $_enabled = TRUE;
    protected $_levels = array('ERROR' => '1', 'DEBUG' => '2', 'INFO' => '3', 'ALL' => '4', 'USER_INFO' => '5');

Answer:

I realize this question is rather old, but I ran into the same problem myself and was able to modify the Log library to fix it.

modify the write_log function in Log.php as follows:

  public function write_log($level = 'error', $msg, $php_error = FALSE)
    {
        if ($this->_enabled === FALSE)
        {
            return FALSE;
        }

        $level = strtoupper($level);

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



        $filepath = $this->_log_path.'log-'.date('Y-m-d').'.php';
        $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') ? ' -' : '-').' '.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;
    }

You’re then able to specify an array in your config file:

$config['log_threshold'] = array(3, 1);

And then your log file will look something like this:

ERROR - 2013-07-24 13:50:04 --> Severity: Warning  --> 
INFO  - 2013-07-24 13:50:04 --> The purpose of some variable is to provide some value.
ERROR - 2013-07-24 13:50:06 --> 404 Page Not Found --> 404.shtml

Answer:

quickfix tested on codeigniter 2.1.4

copy

/system/libary/log.php

to

/application/libary/log.php

add following lines before $filepath (line 86)

// remove all DEBUG messages
if ( $this->_levels[$level] == 2 )
{
return FALSE;
}

Answer:

a better way i will sugeest is to use the file sugested by codeigniter.
I had the same problem and it foxed it. check it out here https://github.com/EllisLab/CodeIgniter/wiki/Custom-Logging-Threshold
