   Hello!

   I have a problem with my first plugin, because I don't know, how the category_save_pre filter works.

   The plugin should automatically select the category, if there is only one category. I know, there's a setting for default_category, but I use another plugin, which exclude for certain users the default_category.
   

   function chooseCategory($id)
   {
   	$cat = get_categories(array('hide_empty'=>FALSE));
   	if (count($cat) == 1)
   	{
   		$id = $cat[0]->cat_ID;
   	}
   	return $id;
   }
   add_filter('category_save_pre', 'chooseCategory');

   What kind of parameters do I get for chooseCategory and what should be returned by this function?

   Thanks
   crille
