I found this bit of code from back in 2006, and it makes sense to me:

use constant ALLOWED_HTML => (

'a'=>{args=>{'href'=>'url'}},
'b'=>{},'i'=>{},'u'=>{},'sub'=>{},'sup'=>{},
'em'=>{},'strong'=>{},
'ul'=>{},'ol'=>{},'li'=>{},'dl'=>{},'dt'=>{},'dd'=>{},
'p'=>{},'br'=>{empty=>1},'blockquote'=>{},

)

But putting it in there causes a server error.

How can I parse allowed HTML so that people can embed stuff like this?

Thanks!

It cant be easier to do something like this. Here is what you do for all the noobs out there

-In wakaba, open your config.pl file. Scroll down to the very bottom where it says "1;". It should be the last line.

Above that last line, there is this "# no encoding; # Uncomment this if you uncommented the "use encoding" at the top of the file"

IN the middle of both those lines, put this code (as shown above)
use constant ALLOWED_HTML => (
'a'=>{args=>{'href'=>'url'},forced=>{'rel'=>'nofollow'}},
'object'=>{forced=>{'width'=>'425','height'=>'350'}},
'param'=>{args=>{'value'=>'url'},forced=>{'name'=>'movie'}},
'embed'=>{args=>{'src'=>'url'},forced=>{'type'=>'application/x-shockwave-flash','wmode'=>'transparent','width'=>'425','height'=>'350'}},
'b'=>{},'i'=>{},'u'=>{},'sub'=>{},'sup'=>{},
'em'=>{},'strong'=>{},
'ul'=>{},'ol'=>{},'li'=>{},'dl'=>{},'dt'=>{},'dd'=>{},
'p'=>{},'br'=>{empty=>1},'blockquote'=>{},
);

--------

The final statement should read"

# no encoding; # Uncomment this if you uncommented the "use encoding" at the top of the file
# Allowed HTML tags and attributes. Sort of undocumented for now, but feel free to
# learn by example.
use constant ALLOWED_HTML => (
'a'=>{args=>{'href'=>'url'},forced=>{'rel'=>'nofollow'}},
'object'=>{forced=>{'width'=>'425','height'=>'350'}},
'param'=>{args=>{'value'=>'url'},forced=>{'name'=>'movie'}},
'embed'=>{args=>{'src'=>'url'},forced=>{'type'=>'application/x-shockwave-flash','wmode'=>'transparent','width'=>'425','height'=>'350'}},
'b'=>{},'i'=>{},'u'=>{},'sub'=>{},'sup'=>{},
'em'=>{},'strong'=>{},
'ul'=>{},'ol'=>{},'li'=>{},'dl'=>{},'dt'=>{},'dd'=>{},
'p'=>{},'br'=>{empty=>1},'blockquote'=>{},
);
1;

The when you embed a video, simply just copy the embed code from youtube, etc and just paste it in the textbox as is.
