HTML Purifier Plugin for Joomla

18th October 2010 in Coding Tags: joomla, open-source, programming

Html purifier is a Joomla plugin based on the HTML Purifier library.

This extension's goal is to clean the xhtml code of the Joomla content items from eventual validation errors.

It may be used also in another ways, for example to filter data coming from comments or forum posts to prevent XSS attacks.

Usage

After having installed the plugin, you need to activate it by going in "Extensions > Plugin manager > HTML purifier".

In the plugin page you will see also some options that you can tweak:

  • Tidy Level: High, Medium, Heavy;
  • Doctype: Xhtml 1.0 Transitional, Xhtml 1.0 strict, Html 4.0 Transitional, Html 4.0 Strict;
  • Linkify: converts automatically every string starting with http:// in a link.
  • Trusted HTML: if set "no" it doesn't allow to use script and style tags in Joomla content items.
  • Proprietary CSS: if set to "on" allows the use of non standard css properties.
  • HTML Purifier Cache: use HTML Purifier built in cache to avoid performance issues.

Deactivate specific content items just by inserting {disablepurifier}.

It would be good to insert the command in an HTML comment (using the HTML mode of your Joomla editor):

<!-- {disablepurifier} -->

This way you avoid showing the string {disablepurifier} in your content items if for some reason you deactivate the plugin.

Demo

Here it is a simple demo, but look at the official HTML Purifier demo to get a better idea.
