How to save error logs in file in Codeigniter 3

Leave a reply

Hello World, Welcome to ProjectsPlaza.com. Today I am going to discuss how to save error logs in the file in Codeigniter 3. Sometimes we need to save the errors in our development process. We can do this with a very easy step.

  • Open application/config.php
/*
|--------------------------------------------------------------------------
| Error Logging Threshold
|--------------------------------------------------------------------------
|
| You can enable error logging by setting a threshold over zero. The
| threshold determines what gets logged. Threshold options are:
|
|   0 = Disables logging, Error logging TURNED OFF
|   1 = Error Messages (including PHP errors)
|   2 = Debug Messages
|   3 = Informational Messages
|   4 = All Messages
|
| You can also pass an array with threshold levels to show individual error types
|
|   array(2) = Debug Messages, without Error Messages
|
| For a live site, you'll usually only enable Errors (1) to be logged otherwise
| your log files will fill up very fast.
|
*/
$config['log_threshold'] = 1;

You can change the above threshold according to the requirements. They have defined all options.

It will save the error in the application/logs directory.

Make sure your logs directory has writable permission

Hello World, Today i am going to create a custom library in codeigniter 3. Library refers to a class which is location in application/libraries folder. This folder contains only user defined libraries. Codeigniter have their own library which is located in system/libraries.

We should not modify the core library of any framework or any CMS becuase when you will update your system, your changes will disappear. Codeigniter provides facility to extend the core library classes and add some additional feature in it. In codeigniter, we can perform following things with library.

  • Create library from scratch
  • Extend the functionality of existing library
  • Replace the functionality of existing library
