Codeigniter, Displaying results from database - codeigniter

Question

I am new to CI, I've been working on this for hours with no success, please help! I am trying to generate user profiles by retrieving information from a database and displaying it in the view (using the USERID). I am getting both an Undefined Variable Error and Trying to Get Property Out of Non-Object error. Here is my code:
Model:
public function my_data()
{
$userid = $this->session->userdata('userid');
$data = array();
$this->db->select('*');
$this->db->from('user_profile');
$this->db->where('userid', $userid);
$query = $this->db->get();
return $query->result();
}
Controller:
public function profile()
{
$data['query'] = $this->user_model->my_data();
$this->load->view('header_loggedin');
$this->load->view('sidebar_left');
$this->load->view('user/user_profile', $user);
$this->load->view('footer');
}
View:
<div class="control-group">
<i class="icon-user"></i>
Name: <?php echo $row->name; ?>
</div>
<div class="control-group">
<i class="icon-home"></i>
Location: <?php echo $data->location;?>
</div>
<div class="control-group">
<i class="icon-briefcase"></i>
Occupation: <?php echo $data->occupation;?>
</div>
Thanks so much in advance, I feel like I have tried everything!

Hi as new to CI you will face some problems but later you will enjoy it here are some simple stuff you are doing wrong
Model
public function my_data()
{
$userid = $this->session->userdata('userid');
$data = array();
$this->db->select('*');
$this->db->from('user_profile');
$this->db->where('userid', $userid);
$query = $this->db->get();
//this will return multiple rows or object of arrays
//return $query->result();
// you need to send only single row
return $query->row();
}
Controller
public function profile()
{
// in data array key name should be same which you will pass to view
$data['row'] = $this->user_model->my_data();
$this->load->view('header_loggedin');
$this->load->view('sidebar_left');
$this->load->view('user/user_profile', $data);
$this->load->view('footer');
}
View
<div class="control-group">
<i class="icon-user"></i>
Name: <?php echo $row->name; ?>
</div>
<div class="control-group">
<i class="icon-home"></i>
Location: <?php echo $row->location;?>
</div>
<div class="control-group">
<i class="icon-briefcase"></i>
Occupation: <?php echo $row->occupation;?>
</div>
for more information please read CI user guide you will understand so many stuff from there CI user guide

Answer 2

here change $user to $data
public function profile()
{
$data['result'] = $this->user_model->my_data();
$this->load->view('header_loggedin');
$this->load->view('sidebar_left');
$this->load->view('user/user_profile', $data);
$this->load->view('footer');
}
then if your query returns only one row , you can use
return $query->row_array();
instead of
return $query->result();
in view you can now use
Name: <?php echo $result['name']; ?>
Location: <?php echo $result['location'];?>
Occupation: <?php echo $result['occupation'];?>
