html to BB conversion?

[jap]

Hi,

would it be possible to convert my html (like in the editor) to the BBcode
I've found out in the codes that Vb is already doing this... although I can't figure out how to do this on other pages of my website.

My BBcode to HTML parser works but now I want to parse the content of my Editor to BBcode
I've been looking around in the function files and this is what i've got:

$bbcode = convert_wysiwyg_html_to_bbcode($html);

(from includes/functions_wysiwyg.php)

and then I get the following error:
Fatal error: Call to a member function clean_gpc() on a non-object in /home/z-spot/webserver/forum/includes/functions_wysiwyg.php on line 94
I've found the clean_gpc() function but when I include this function into my testfile nothing changes :s

This is the function:
function &clean_gpc($source, $varname, $vartype = TYPE_NOCLEAN)
{
if (!isset($this->registry->GPC["$varname"])) // limit variable to only being "cleaned" once to avoid potential corruption
{
$sg =& $GLOBALS[$this->superglobal_lookup["$source"]];

$this->registry->GPC_exists["$varname"] = isset($sg["$varname"]);
$this->registry->GPC["$varname"] =& $this->clean(
$sg["$varname"],
$vartype,
isset($sg["$varname"])
);
}

return $this->registry->GPC["$varname"];
}
(Source: class_core.php)

Would anyone be able to help me with this and figure out how I would be able to convert html code to BBcode

Thanks,
Jasper
