Hooks used UserLoginComplete PersonalUrls

The LastLoginTime extension is a simple one which displays User's Last login time at the top of the page as a personal url. I wrote this extension because i thought this will be a good idea to display last login time for the users. It may help others if they have same requirement for their application.

Usage

This extension is as mentioned a simple one so usage is not a big deal. Just confirm the table and column names in the code are according to your database. Install it and that's it.

Installation

• Add the following code at the bottom of your LocalSettings.php :

  require_once "$IP/extensions/LastLoginTime/LastLoginTime.php";
  

•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
