[wp-hackers] quick way to add dozen of new capabilities to existing role?

[Davit Barbakadze]

I've considered that, but potential number of queries kinda frightened
me away. Looking at the source I just made up something like this:

function add_caps_to($roles, $caps)
{
   $r = new WP_Roles;

   if (!is_array($roles))
       $roles = array($roles);

   foreach ($caps as $cap)
       foreach ($roles as $role)
           $r->roles[$role]['capabilities'][$cap] = 1;

   update_option( $r->role_key, $r->roles );
}

Potentially it can simultaneously assign array of capabilities to a
several roles at ones and then make just one query at the end.

I wonder if there could be a problem with this?
