sanitizing tag extension parameters for js output
|
|
I just threw together a simple tag extension to embed a twitter live stream search widget from
http://twitter.com/about/resources/widgets/widget_search
in a wiki page. It just takes the following parameters from $input:
title=<title>
subject=<subject>
query=<query>
These get dropped into a <script> that is returned. It works, but now I'm wondering what I should do to sanitize the values of title, subject, and query. I don't want to just use In the js, the values are all inside single quotes. I was thinking that I would use strip_tags combined with substituting single quotes with '
preg_replace('/\W/', '', $t)
would disallow hashtags and @'s, right?
