Meta-Lite Widget: my first WordPress plugin

Based on tutorials from Widgetizing Plugins, Lisa Stewart, Emanuele Feronato, and especially Hrw website; here is my first plugin for WordPress: Meta-Lite Widget for your sidebar

All it does is showing the Register/Admin and Login/Logout links. It works on WordPress 2.6. You can try it with different version of WordPress and let me know if it works on yours. Meta-Lite uses its own namespace so it won’t conflict with the default Meta Widget that comes with WordPress. You can have them side by side.

Install

  • Download the zip (link below), unzip to get the widget-meta-lite.php file
  • Put it under /wp-content/plugins/widget-meta-lite.php
  • You will see the widget listed under Plugin Management, click to activate it

Un-install

  • Just delete the file /wp-content/plugins/widget-meta-lite.php

Usage

  • The widget should now be available for use in Design/Widgets
  • Use it as any other Widget ;-p. Drag and drop it to your sidebar

Download widget-meta-lite.zip

    Thanks for that. I needed it for a project I’m throwing together in a hurry… was going to have to build it myself but you saved me the trouble.
