I have to use multiple forms in a page.

My Problem:
I can not stop the code check the unsubmitted form with the other ?automaticly?.
*Errors are different. One's error is not shown under other's error list.

I have a multi-page form. Basically, you have to store the results of the first form somewhere. I store it in the session object, which is saved to the db. Not the cookie, which is unsafe and can only store about 4k.

Code:

if ($this->form->valid) {

  // validate your first form here

  // save your form to the user's session
  $this->session->set_userdata($post);

  // redirect to second form
  redirect('subscription/review');

}

Then I just pull in the old form data as if it was part of the second page form

Code:

function review() {

  // get data from the first form if you need it to create the second form/page
  $session_form = $this->session->all_userdata();

  // create the second form here

  if ($this->form->valid) {

    // get the data from the first form
  
    $form_data = $this->session->all_userdata();

    // validate second form here

    // save any data you need for thankyou page
    $this->session->set_flashdata($data);
    redirect('subscription/thankyou');

  }
}

Note that your thankyou function should clear out all session data to be safe.

Code:

function thankyou() {
  $ty_msg['welcome_message'] = $this->session->flashdata('welcome_message');
  $this->load->view("thankyou", $ty_msg);
  $this->session->sess_destroy();
}

Works well, but you have to make sure sessions are working properly and that stuff like AJAX calls are not reseting session data.

HTH,

Chris.
