Problem with $user->syncGroups

[ondequadre]

I don't know exactly if I am doing something wrong or there is a problem with syncGroups()

If I do this:

$groups = "'" . implode("', '", $this->request->getPost('groups')) . "'";
$user->syncGroups($groups);

Returns this error:

CodeIgniter\Shield\Authorization\AuthorizationException #401
'admin', 'user' is not a valid group. 

if I manually insert the groups:

$user->syncGroups('admin','user');

then it works...

It is true, 'admin', 'user' is not a valid group.

See https://github.com/codeigniter4/shield/blob/develop/docs/quickstart.md#adding-a-group-to-a-user

Thanks kenjis, but what I'm trying to do is not add a group to the user while creating. But I'm trying to change groups for a user while editing. In fact if I write the groups dynamically it gives me the error, but if I write the command manually in the code it works.

This does not work:

            $data = [
                'firstname' => $this->request->getPost('firstname'),
                'lastname' => $this->request->getPost('lastname'),
                'email' => $this->request->getPost('email'),
                'company' => $this->request->getPost('company')
            ];

            $user  = $this->userModel->findById($id);

            $user->fill($data);

            if ($this->userModel->save($user))
            {
                $groups = "'" . implode("', '", $this->request->getPost('groups')) . "'";

                $user->syncGroups($groups);
            }

CodeIgniter\Shield\Authorization\AuthorizationException #401
'admin', 'user' is not a valid group. 

This works:

            $data = [
                'firstname' => $this->request->getPost('firstname'),
                'lastname' => $this->request->getPost('lastname'),
                'email' => $this->request->getPost('email'),
                'company' => $this->request->getPost('company')
            ];

            $user  = $this->userModel->findById($id);

            $user->fill($data);

            if ($this->userModel->save($user))
            {
                $user->syncGroups('admin', 'user');
            }

See the docs.
You need to pass string params to syncGroups():

$user->syncGroups('admin', 'beta');

But you pass string "'admin', 'user'". So it does not work.

Do you have any suggestions? Because I have tried several solutions I still have not been able to solve.

Thank you kenjis I solved it, I admit it was something completely new to me, I didn't know this possibility existed.

$user->syncGroups(...$this->request->getPost('groups'));
