I have a listener to add elements and attributes to the htmlpurifier config.

I can get the attributes like this:
$_attr = $_data->get('HTML.AllowedAttributes');

But I can't then set them.
Quote: [13-Dec-2014 13:54:45 Europe/Dublin] PHP Fatal error: Cannot set directive after finalization invoked on line 158 in file /Applications/AMPPS/www/demo7.ultrabubble.com/modules/ujWorkbook/include.php in /Applications/AMPPS/www/demo7.ultrabubble.com/modules/jrCore-release-5.2.16/contrib/htmlpurifier/HTMLPurifier.standalone.php on line 2607

Adding the attribute also doesn't work (seems like this is how it is done in config in the htmlpurifier docs.

It looks like the Jamroom iframe listener turns on a filter rather than adding to the allowed attributes and elements, and I can't get much info from the htmlpurifier docs. Any suggestions would be very much appreciated.

I will check this out Steve - sounds like we may need to tweak the position the event is being triggered in for this to work.

Steve - I've got this fixed for the Jamroom Core 5.2.18 release - inside your listener you'll want to set BOTH the elements and attributes. For example, to add the "blockquote" element and allow the "class" attribute you would do:

$_elem = $_data->get('HTML.AllowedElements');
$_elem['blockquote'] = 1;
$_elem = implode(',', array_keys($_elem));
$_data->set('HTML.AllowedElements', $_elem);

$_attr = $_data->get('HTML.AllowedAttributes');
$_attr['blockquote.class'] = 1;
$_attr = implode(',', array_keys($_attr));
$_data->set('HTML.AllowedAttributes', $_attr);

Hope this helps!

That's great, thanks Brian.

I'll give this a try later on.
