Controller flow when processing forms - El Forum - 10-17-2008

Hi all! Is there a standard way that form processing is implemented in CodeIgniter? Here are the high-level steps I have in mind:
1. Display empty form
2. Submit
A. If there are validation errors, redisplay the form with the errors.
B. If there are no validation errors, display a success page.
How would I set up my controller methods? Would I have one method to display the view and another method to process the view? (Or would both go in the same method?)
Btw, I already know the basics of CodeIgniter (including the validation library).
Thanks!

To put it simply without code:
1. Set validation rules and field names.
2. Check to see if the form validates.
3. If false (also the default), display the form w/ any errors.
4. If true, process the form then display a message, redirect the page, or whatever you want.

Here's default skeleton for a controller function that processes a form. I tend to post and get to the same action:
Code:
function contactus() {
if($_SERVER['REQUEST_METHOD']=='POST'){
$this->load->library('Validation');
$this->load->config('cfg_forms');
$this->validation->set_fields($this->config->item('form_contactus_fields'));
$this->validation->set_rules($this->config->item('form_contactus_rules'));
$this->validation->set_error_delimiters('<div>','</div>');
if ($this->validation->run()) {
// Do stuff with the form data
// Choose to redirect here or show the same form again
}
}
$this->load->view('contactus');
}HTH

Thanks Aken & Mirage! That really cleared things up.
