Really my question has more to do with the server-side scrubbing of html that’s accepted via the WYSIWYG form component. Right now I’m leaning toward using htmlpurifier.org’s library. I’m using php strip_tags() function elsewhere. Anyone have an advice/preferences/recommendations?
strip_tagsis very vulnerable – you might as well do nothing. HtmlPurifier is probably as good as it gets with html-cleansing. If you are really serious about security, you should probably disallow html input entirely, but I realise that’s not always an option.
