Split form in many pages... better way?

[eluser]PhilTem[/eluser]
To avoid manipulation of data you could just add an encoded string that matches the previous form's post data to your new form.

That means:

Code:

// In controller of second form display method
$previous_form = $this->input->post();
$token = $this->encrypt->encode(json_encode($previous_form));

$data = array('hidden_input' => json_encode($previous_form), 'token' => $token));

And for validation you can easily run it as

Code:

$previous_previous_form = $this->input->post('hidden_input');
$token = $this->input->post('token');

if ( $previous_previous_form == $this->encrypt->decode($token) )
{
  // is valid
}
else
{
  // is not valid i.e. manipulated
}

This process can be done over and over again for each form page except you have to generate new tokens and take the right post fields into your hidden input.


NOTE
However, I do not recommend to use this (see posts above). I'd really store all data in a flat file or db. It is just shown by me since you were asking which ways there are and I am solely elaborating one of the possible ways

PS: I really tried auto-completing some code parts using ctrl+space... But unfortunately these forums don't have auto-completion
