Hello All,

I'm new to CI, But learning as quick as possible. Now, I'm developing an News Board Application. In this i'll add news & update it.

Code:
class NewsController extends Controller {
    function NewsController()
    {
    parent::Controller();    
    }
    function index()
    {
    $this->load->model('newsmodel');
    $data['news_collection']=$this->newsmodel->getNewsIndex();
    $this->load->view('svs_view',$data);
    }
function addnews()
    {
    $title=$this->input->post('vTitle');
    $name=$this->input->post('vContent');
    $date=$this->input->post('vDate');
    $this->load->model('newsmodel');
    $data['rows_affected']=$this->newsmodel->addNews($title,$name,$date);    
    self::index();
    
    }
}



For adding News,
My URL will looks like - <b>http://localhost/index.php/newcontroller/addnews</b>. After successfully adding Data to the Database I’m calling the Index () function. But URL is remaining same as <b>http://localhost/index.php/newcontroller/addnews. <br>Once when i Press "REFRESH" Button Data is Repeatedly Inserting into database. I wanted to have U</b>RL looks like <b>http://localhost/index.php/newscontroller</b> So that Data won’t be inserted with out necessary.
Pls tell some way to control this Refresh problem.

Instead of using

Code:
self::index();

why dont you use

Code:
redirect('/newscontroller/', 'refresh');

as long as nothing is being written to the browser this will work. See the link below

You could use sessions to 'remember' that the same user(or anything) has inserted data then prevent it.

Why not just stop clicking refresh? ;-)

Prevention is better than cure? Smile
