Undefined property

The problem is this line doesn't return what you think it does

PHP Code:

return $this->db->get('product'); 


You need to Generate Query Results from the returned value - they cannot be read directly. You need something along these lines

PHP Code:

$this->load->model('Product');
$rows = $this->Product->get_product()->result(); 
foreach($rows as $row){
... 


Or, you could have the model return an actual result set

PHP Code:

function get_product()
{
       $this->load->database();
       return $this->db
                        ->get('product')
                        ->result();
} 


Then your controller code would work as shown in your original post.
