C4 Latest version shield manage users

This code is dangerous. Because an attacker  can send any values to your server.
Be sure that $id does not have invalid value as the id value (number only?) before running this code.

PHP Code:

$validation->setRules([
        'username' => [
                'rules'  => 'required|is_unique[users.username,id,{$id}]',
                'errors' => [
                    'reuired' => 'username required.'
                    'is_unique'  => 'username: ({value}) already taken',
                ],
            ],
        'email' => [
                'rules'  => 'required|is_unique[auth_identities.secret,user_id,{$id}]'
                'errors' => [
                    'reuired' => 'email required.'
                    'is_unique'  => 'email: ({value}) already taken',
                ],
            ],
    ]);
