User:Jabrwocky7/polldaddy

This is an extension I wrote for MediaWiki to insert polldaddy.com polls into Lostpedia. It was originally based off of Sylvain Machefert's googlevideo and youtube video extensions, but has been re-written to use parameters within the tag to make it more elegant and secure.

Usage: <polldaddy pollid="12345"/> Note: In version 1.3 the height and width parameters are no longer used.

Using the javascript code from the polldaddy.com website:

<script type="text/javascript" language="javascript" src="http://s3.polldaddy.com/p/12345.js"></script><noscript> <a href ="http://answers.polldaddy.com/poll/12345/" >Is the sky blue?</a>  <br/> <span style="font-size:9px;"> (<a href ="http://www.polldaddy.com">  surveys</a>)</span></noscript>

Use this tag in Mediawiki:

<polldaddy pollid="12345"/>

Here's the code:
