controller:

public function view_products() {

            $id = $this->uri->segment(3);
            $data['products'] = $this->user->viewprod($id);
            $this->load->view('product_viewpage', $data);

    }

model:

  public function viewprod($id) {
          $query = $this->db->query("SELECT * from product_table WHERE product_category = '$id'");
        $r = $query->result();
        return $r;

    } 

Answer 1

In your model you are using result() function and this will return you result in object form.

$query->result();

Solution 1:

If you still want to use result() function than you need to change your view as:

$id = $alls->product_id; 
$name = $alls->product_name; $description = $alls->product_description; 
$price = $alls->product_price; 
$picture = $alls->img_name. $alls->ext;

Solution 2:

If you don't want to change your view file than you must need to use result_array() in your model as:

$query->result_array(); // will return you result in array format.
