{
$this->db->where('id', $id);
$query = $this->db->get('users');
return $query->result();
}
function updatebyid($userid, $data)

Answer 1

You are getting array to string conversion error because your model :
$this->model_user->get_user_by_id($this->session->userdata('id'))
returns an array of objects. To remedy your problem, you could loop the result
or if you only need the first row of your result you could do this:
$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));
if ($this->model_user->updatebyid($userid[0]->id, $data))
or perhaps you can modify your model like this:
function get_user_by_id($id)
{
$this->db->where('id', $id);
$query = $this->db->get('users');
return $query->row(); // use row if you only want the first row of the result of your query
}
controller:
$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));
if ($this->model_user->updatebyid($userid->id, $data))
***************************************************************************************
or a more comprehensive model so you wont need to change your controller:
function get_user_by_id($id)
{
$this->db->where('id', $id);
$query = $this->db->get('users');
$result = $query->row();
return ($result) ? $result->id : false;
}

Answer 2

You are passing array of user details instead of user id in update
change this line
$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));
to
$userid = $this->session->userdata('id');
in function edituserinfo() of controller

Answer 3

$userid = $this->model_user->get_user_by_id($this->session->userdata('id'));
In the above line you are querying the database which will return an array.
Instead set the user ID as below
$userid = $this->session->userdata('id');
