codeigniter error using JOIN to select single row - codeigniter

Question

Im trying to get joins to work when selecting a single row. here is my code:
model:
function view($id) {
$this->db->select('c.name
,c.phone
,c.active
,c.website
,c.date_acquired
,con.firstName');
$this->db->from('company c');
$this->db->join('contacts con','c.primary_contact = con.id','left');
$this->db->where('id', $id);
$query = $this->db->get();
return $query->row_array();
controller:
public function view($id)
{
$this->load->model('Company_model');
$data['data']= $this->Company_model->view($id);
$this->load->view('templates/header');
$this->load->view('company/view', $data);
$this->load->view('templates/footer');
}
the error im getting is:
Fatal error: Call to a member function row_array() on a non-object in
/home/techf/public_html/application/models/company_model.php on line
35
and line 35 in the above code is:
$query = $this->db->get()
is this not correct when dealing with joins and a row array?

Here is my controller:
public function view($id)
{
$this->load->model('Company_model');
$data = $this->Company_model->view($id)->row();
$this->load->view('templates/header');
$this->load->view('company/view', $data);
$this->load->view('templates/footer');
}
and my model:
function view($id) {
$this->db->select('*');
$this->db->from('company');
$this->db->join('contacts con','c.primary_contact = con.id','left');
$this->db->where('id', $id);
return $this->db->get('company');
}
but now im am getting error:
Fatal error: Call to a member function row() on a non-object in
/home/techf/public_html/application/controllers/company.php on line 21

Here you go model code
public function get_joins($table,$value,$joins,$where,$order_by,$order)
{
$this->db->select($value);
if (is_array($joins) && count($joins) > 0)
{
foreach($joins as $k => $v)
{
$this->db->join($v['table'], $v['condition'], $v['jointype']);
}
}
$this->db->order_by($order_by,$order);
$this->db->where($where);
return $this->db->get($table);
}
and in your controller aceess it like
$value=('restaurantorders.*,restaurant.Name,restaurant.CurrencyId,currency.*,orderpaymentdetail.Gateway ');
$joins = array
(
array
(
'table' => 'tk_restaurant',
'condition' => 'restaurant.Id = restaurantorders.RestaurantId',
'jointype' => 'inner'
),
array
(
'table' => 'tk_currency',
'condition' => 'restaurant.CurrencyId = currency.Id',
'jointype' => 'inner'
),
array
(
'table' => 'tk_orderpaymentdetail',
'condition' => 'restaurantorders.Id = orderpaymentdetail.OrderId',
'jointype' => 'inner'
),
);
$data['order_detail'] = $this->general_model->get_joins($data['tbl'],$value,$joins,array('OrderStatus'=>'Confirm','restaurantorders.Id'=>$orderid),'restaurantorders.Id','desc')->row();

Answer 2

note that on the model i test first if num_rows() is greater than 1 before sending on the row and if not return false.
Note that on my this->db->get i removed the name of the table, because you already added it on the from method.
$this->db->select('*')
->from('company c');
->join('contacts con','c.primary_contact = con.id','left');
->where('id', $id);
$query = $this->db->get();
return $query->num_rows() >= 1 ? $query->row() : FALSE;
on your COntroller
on on the data variable you forgot to add a key, this will be used when you access the variable/object on you're view, example is $data['contacts']
public function view($id)
{
$this->load->model('Company_model');
$data['contacts'] = $this->Company_model->view($id);
$this->load->view('templates/header');
$this->load->view('company/view', $data);
$this->load->view('templates/footer');
}
on your VIEWS
access the contacts key that you assigned earlier on you're controller.
<?
if(!empty($contacts))
{
print_r($contacts);
}else{
echo 'No data';
}
?>
to show the structure of your query on a standard MySQL query
you could comment out the return on you're model and add this snippets of code just after the $this->db->get() method.
echo $this->db->last_query();
die();
This will echo out what query was made, and you can run it on phpmyadmin and compare if the values returned are right.

can you try it like this maybe?
model: (i'm not sure in which table is id and in which primary_contact, so change that if i made a mistake)
function view($id) {
$this->db->join('contacts','company.primary_contact = contacts.id','left')
->where('id', $id);
$query = $this->db->get('company');
return $query->row();
}
in controller call it like this:
$data['result'] = $this->company_model->view($id);
then access object in view:
<?=$result->id?> (etc.)
