woot plugin

This plugin allows you to insert woot.com's current product information into your wiki. woot.com is a popular site which offers a single product a day at a (usually) low price. While they do offer an RSS feed, it's very minimal and doesn't directly relate to their current product. This plugin displays the product description, the price (+ shipping), and the product image. It does all this by using screen scraping methods, so if it's the case the plugin ever breaks, it's probably due to a site design change on their part. Oh well.

Update 5/19/2008:

• Fixed the broken screen scraping code, woot changed site design slightly.

Update 3/27/2008:

• Added the “woot off” detection logic.
• Threw in an old school blink tag!

Usage is as simple as :

{{woot}}

Place the following code into lib/plugins/woot/syntax.php

<?php
/**
 * Woot Plugin
 * 
 * woot.com is a fun little website which offers a single deal on
 * some techie gadget daily. Sometimes the deals are great, but 
 * generally it's crap. This plugin screen scraps woot and grabs
 * the current product price, title, and image.
