Module development and code questions

hey, everybody
Can you help me?
In drupal, how to set attribute for radiobutton in group?
I have an array to create a group radio buttons:
$form['radio_group'] = array('#type' => 'radios',
'#title' => t('Radio'),
'#default_value' => t('1'),
'#options' => array('option1'=>t('option 1'),'option2'=>t('option 2'),'option3'=>t('option 3'))
);

I have run drupal4.6 and module FCKeditor, everything works well, however i don't know how to disable function "Create New Folder" in Upload page.
For my purpose, i only allow users can upload to available folders (ex:Image, Flash, Media), but they can't create any new folder through browser upload module of FCKeditor.

Please help me how to do it.
Thank you very much.

Not sure where this error is coming from. I've seen it a few times, most recently in the admin/views page for the views module. It's a difficult error to troubleshoot bc I'm not positive it's a views problem. I tried removing all of the other modules and it still gave me the error.

Help?

In creating a webmedia module that will allow users to post Online TV and Radio stations with the feed embeded into the webpage I would like to add the option not to show the real url for the feed... But rather have it to to a drupal url such as www.example.com/webfeed/5 that would actually be the feed.

What is the best way to go about this without having to added each redirect into the .htaccess file.
