[edit] What can this extension do?

This 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.

[edit] 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.

[edit] Installation

  1. Copy the code given at LastLoginTime.php
  2. Save it in extensions directory as LastLoginTime.php
  3. Include it in LocalSettings.php
  4. That's all you need to do.

[edit] Changes to LocalSettings.php

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