validation and data afterwards

Ah

well you could do something like this in your controller "form.php"

Pseudo code:

Code:

function index() {
   // show form
   $this->load->view("form.html");
}

function process() {
    // Get the posted stuff and do something
    // Use validation library
    
    // If everything is okay:
    $this->redirect("/form/success");
}

function success() {
     $this->load->view("form_success.html", $data);
}

By redirecting the user to a thank you page they can refresh that page but it will still only call /form/success/ so no data is being reprocessed. You can fill /form/process/ with whatever is needed to do with the received data.

If you hit the Back button from the success-page it should go to the form page (/form/index/) as it skips the header redirect which didnt produce any cachable data as you didn't output anything.

Hope this helps (and makes sense).
