Just change these code in model

public function categorylist()
{
$query=$this->db->get('category');
echo $query->num_rows();
if($query->num_rows()>0)
{
    return $query->result();
}
else
{
   return 0;    
} 
}

Now in controller if 0 get then

public function categorylist()
{
$data['categorylist']=$this->userprocessmodel->categorylist();
if($data['categorylist']=='0')
{
   $datanone['categorylist']='None';
   $this->load->view('user/home',$datanone);
}
else{
 $this->load->view('user/home',$data);
}
}
