Codeigniter when i click delete i want pop up notification if if click yes or not

Model:

 function delete_exchange($ExchangeRateId) {
    $this -> db -> where('ExchangeRateId', $ExchangeRateId);
    $this -> db -> delete('exchange_rate');
}

Controller:

function delete($ExchangeRateId) {
        $user_type = $this -> session -> userdata('user_type');
        if ($user_type != "admin") {
            redirect(base_url() . 'user_admin/login');
        }
        $this -> all -> delete_exchange($ExchangeRateId);
        redirect(base_url() . 'exchange/index');
    }

The delete button is clear, here I want a notification like pop up yes or then must run the action I mean delete on

Answer

Do like this in your view..

<a href="<?PHP site_url('delete/').$ExchangeRateId;?>" onclick="return deletechecked();">delete<?a>

    function deletechecked()
    {
        if(confirm("Delete selected messages ?"))
        {
            return true;
        }
        else
        {
            return false;  
        } 
   }
Answer

you need to do that client side.. in your view... onclick event of a button where you want the conformation use confirm()...

add this to you button..

<button onclick="confirmation()" />

function confirmation()
{
   var r=confirm("are you sure to delete?")
   if (r==true)
  {
    alert("pressed OK!")
    // call the controller
  }
  else
  {
   alert("pressed Cancel!");
   return false;
  }
}
