[Mediawiki-l] custom extension including <script> tags

Tue Dec 7 22:15:33 UTC 2004

Thanks Jamie, that works a charm!

You don't have any idea how I can resolve my css issues as well by any
chance?

"2. I also need to include some custom css code for this extension.  I've
done this by adding it to the monobook css file, but I'd prefer an option
that wont get broken whenever MediaWiki is updated.  Is there an approved
method of adding custom content within the <head></head> section?"

;-)

Try placing the code in a seperate file and referencing it in a single
line. This works for me:

function renderRandomQuote( $input )
{
       $output = '<script type="text/javascript"
src="http://www.chiefdelphi.com/forums/xml/spotlight_js.php"></script>
<a href="http://www.chiefdelphi.com/"
title="http://www.chiefdelphi.com/"><img
src="http://furc.zapto.org/wiki/stylesheets/monobook/external.png"></a><span
class="urlexpansion"> (<i>http://www.chiefdelphi.com/</i>)</span>';
    return $output;
}

(This is actually in use on "http://furc.zapto.org/wiki/", using the
tag <randomquote>) I think the code that handles the output doesn't
preserve things within <script> tags, but it will preserve attributes.
