Code Igniter Validation on Error - php

Question

I am pretty knew to code igniter / OOP but I am giving it a shot and a little stumped at this point.
I have 2 functions. One is the search which loads data from a model. The other is the save function.
My issue is, when running save() I am getting errors because its trying ti display the validation errors but we no longer have the data from the database that we got from the search() function.
I feel that it would be redundant to include all the details form the search back into this save function which is why I think I am doing something wrong.
public function search()
{
// Define some vars
$data['title'] = 'Submit Attrition';
$data['js_file'] = 'submit.js';
// Load our helper
$this->load->helper('form');
// Get the user and pass it to the model
$empQID = $this->input->post('empQID');
$data['userDetails'] = $this->submit_model->get_details($empQID);
$data['languages'] = $this->submit_model->get_languages();
$data['types'] = $this->submit_model->get_types();
$data['ratings'] = $this->submit_model->get_ratings();
$data['processes'] = $this->submit_model->get_processes();
// Send the data to the views
$this->load->view('templates/header', $data);
$this->load->view('submit/search', $data);
$this->load->view('templates/footer', $data);
}
/**
* Validate & save attrition submission
*
* #author Carl
* #return void
*/
public function save()
{
$data['title'] = 'Submit Attrition';
$this->load->library('form_validation');
$this->form_validation->set_rules('language', 'Supporting Language', 'required');
// Validation failed, show form w/ validation errors
if ($this->form_validation->run() === FALSE)
{
$this->load->view('templates/header', $data);
$this->load->view('submit/search', $data);
$this->load->view('templates/footer', $data);
}
else
{
// Success : Send data to model
$this->submit_model->save_attrition();
$this->load->view('templates/header', $data);
$this->load->view('submit/success', $data);
$this->load->view('templates/footer', $data);
}
}

I'm not sure I entirely understand your question, but I think I understand what you're trying to do. In CodeIgniter, you do something like this:
class MyController
{
// this controller action will load whether the form is submitted or not
// $user_id is set by the router
public function save($username)
{
// if the users not in the database, throw a 404 error
$user = $this->db->get_where('users', ['username' => $username]);
if(!$user) {
return show_404();
}
// if it's not a post request, then the form hasn't been submitted
// so don't bother validating it
if($router->fetch_method() === 'POST' && $form_validation->run() === TRUE)
{
$user['name'] = $this->input->post('name');
$this->db->update('users', $user);
$this->load->view('success_page');
// return so we don't render the form again
return;
}
// this will happen in all cases, __except__ when the form was submitted
// with valid data
$this->load->view('form');
}
}
I've skipped on details for brevity (like loading the relevant libraries), and because I can't remember all the CI syntax.
