Whitelist Forms in HTML Purifier Configuration

Question

I use HTML Purifier to clean input in my CMS. Many of my clients like to have PayPal donation buttons in their site, but HTML Purifier strips the forms out. I noticed that HTML Purifier has a HTMLPurifier_HTMLModule_Forms class, but I don't know if that does what I want. If it does, how do I enable it?

Thanks!

Looks like I might have to offer a bounty!

Answer 1

$config->set('HTML.Trusted', true);
$config->set('Attr.EnableID', true);

should turn on Forms (I think they’re enabled by default in the trusted set.) Of course, this also allows JavaScript too, so it might not be what you’re looking for...
