Pulling data from form_validation in controller

[eluser]bluematt[/eluser]
I've recently downloaded the 1.7 release to port an app, and I may be being completely dense, but I don't seem to be able to get form data (after being filtered through the form_validation library, hopefully with appropriate data prepping) into the controller.

The

Code:

set_value()

function works fine for the view, but what function/array/variable should I be using to get it into the controller?

e.g.

Code:

class Test extends Controller {
  
  function Test()
  {
    parent::Controller();
  }
  
  function index()
  {
    $this->load->library('form_validation');
    $this->form_validation->set_rules('hash', 'Item to be hashed', 'required|md5');
    
    if ($this->form_validation->run()) {
      $data['hash'] = $_FORM['hash']; // <--  What should I use here to use the
                                      //      form_validation prepped value?
    }
    
  }
  
}

I've scoured the docs, the forums and the library itself to no avail. Have I missed something incredibly obvious?

TIA for any help.

Hi bluematt,

Welcome to CodeIgniter!

It isn't clear, but you can always use the Input class. Once your data us run through Validation has been cleaned. So you can do this:

$this->input->post('some_data');

to gain access to it.

Hope this is helpful.

Thanks for the feedback. Yes, I'd already tried the $this->input->post(), but this doesn't reflect the prepped version of the data, only the raw data from $_POST (presumably after having gone through the XSS filter). I'm happy to use the encrypt() function afterwards on the raw $input->post(), but I thought the point of the data prepping in the form_validation was to remove such things.

Oh well, thank again.

You have to set_fields for the changes to be applied to the $_POST array. $this->input->post() and $_POST are identical.
[EDIT: crap, nvm - that was the old one]

Hi all, is there any concrete solution to this. I'm also wondering how to get the post-validation data inside a controller

Edit: found a solution here: http://ellislab.com/forums/viewthread/95074/
which in fact is the same as above.
