php - codeigniter how to display data base query result as a message in the view and how to redirect same function? -

my model looks:

public function addmobileaction() {        $mobile = $this->input->post('mobile',true);      $qry = 'select * mobile              mobile='.$this->db->escape($mobile);      $query =$this->db->query($qry);       $value=$query->num_rows();      if($value == 0)     {           $mobile_id=$this->db->select('mobile_id')->order_by('mobile_id','desc')->limit(1)->get('mobile')->row('mobile_id');         $mid=$mobile_id+1;          $sql = "insert mobile (mobile,mobile_id)                  values(".$this->db->escape($mobile).",".$this->db->escape($mid).")";                 $this->db->query($sql);                   return "registered sucessfully! id is: ".$mid;      }      else     {             $mobile_id=$this->db->select('mobile_id')->where('mobile', $mobile)->get('mobile')->row('mobile_id');              return "already registered! id: ".$mobile_id;       } } 

my controller is

public function addmobileprocess() {       if(($this->session->userdata('username')!=""))     {         $this->load->library('form_validation');         $this->form_validation->set_rules('mobile', 'mobile', 'xss_clean|min_length[10]|required');           if($this->form_validation->run() == false)         {             $this->home();         }         else         {             $result= $this->contentmodel->addmobileaction();                   $datasucess['mobileid']=$result;                 $data['sucess'] = $this->load->view('sucess', $datasucess, true);                 $this->load->view('index',$data);               }     }     else     {         $this->load->view('login');     } } 

my need have take both return values model , display message in view based on condition checked on model, here view same view data posted.

that means after data submission have redirect function call view , have display "already registered! id: ".$mobile_id; if mobile number registered , "registered sucessfully! id is: ".$mid; if mobile number new.

how redirection done? modification have done. new kind of situation.thanking in advance.

public function addmobileaction() {        $mobile = $this->input->post('mobile',true);      $qry = 'select * mobile              mobile='.$this->db->escape($mobile);      $query =$this->db->query($qry);       $value=$query->num_rows();      if($value == 0)     {         $mobile_id=$this->db->select('mobile_id')->order_by('mobile_id','desc')->limit(1)->get('mobile')->row('mobile_id');         $mid=$mobile_id+1;          $sql = "insert mobile (mobile,mobile_id)                  values(".$this->db->escape($mobile).",".$this->db->escape($mid).")";                 $this->db->query($sql);                   return true;      }      else     {             $mobile_id=$this->db->select('mobile_id')->where('mobile', $mobile)->get('mobile')->row('mobile_id');              return "already registered! id: ".$mobile_id;       } }
