$userdata->set()

[1Unreal]

I'm having some trouble setting options...

I have this
<input type="text" name="set_options[lastfm_username]" />
On modifyoptions template

This on profile_updateoptions plugin
$vbulletin->input->clean_array_gpc('r', array('lastfm_username' => TYPE_NOHTML);
$userdata->set('lastfm_username', $_REQUEST['lastfm_username']);

And this on userdata_start
$this->validfields['lastfm_username'] = array(TYPE_STR, REQ_NO);

But its not updating.

As you have placed the field inside the "set_options" input array, the code is probably more like:
$userdata->set('lastfm_username', $vbulletin->GPC['set_options']['lastfm_username']);

Still doesn't work :(

I took it out of the set options array too and it didn't work.

$userdata->set('lastfm_username', $_REQUEST['set_options']['lastfm_username']);
