user hasRole

[Frank Vèssia]

I cannot understand why i can't get role of user.

$userid = 40;
$role  = $roles->get("premium");
$uid = (int) $userid;
$u = $users->get($uid);
if ($u->hasRole($role)){
 ...stuff
}

i get a fatal error:

Method NullPage::hasRole does not exist or is not callable in this context

Shouldn't it be hasRole("string"); ?

You load the role as object and not as string, and hasRole expects the name (string).

[Frank Vèssia]

already tried using string....

I guess the problem is the user.

If i use this function with current user ($user) it works...

NullPage::hasRole says to me there's no "userpage" found so its returning NullPage, and there's no method on NullPage.

This line failed to load a user:

$u = $users->get($uid);

User ID 40 doesn't exist in the system because anytime PW returns a NullPage that means it didn't find what you were looking for. The best way to check if you got a NullPage is to see if the returned has an ID. So your last section of code should be something like this:

if ($u->id && $u->hasRole($role)){
  ...stuff
}

Btw, ID 40 is the default ID for the 'guest' user account, so it would be unusual if that really is the ID of the user and it didn't load.
