CodeIgniter - save method and redirects - forms

Question

I have a page to manage courses, built with CI 3. When the user hits the save button, the form is submitted to the save method. My problem is how do I redirect the user to the previous page with the form populated with the data inserted?
At the moment what's happening is that after submit, the save method loads the views of the /new page, and the URL stays as /save with the data populated.
Already tried the redirect, but it loses the data the user had inserted.
Here a snippet of my save method:
public function save()
{
$this->checkIsAdmin();
$this->load->helper('form');
$this->load->library('form_validation');
$this->form_validation->set_rules('name', $this->lang->line('common_name'), 'required');
if ($this->form_validation->run() === FALSE)
{
$this->feedback_message->create('Please check fields', 'error');
$this->baseInfo['page_title'] = "Registar novo curso";
$this->mybreadcrumb->add('Registar curso', base_url('course/new'));
$data['schools'] = $this->School_model->listSchools();
$this->load->view('web/top', $this->baseInfo);
$this->load->view($this->templatesFolder.'tabs_start', array('courseId' => 0));
$this->load->view($this->templatesFolder.'manage', $data);
$this->load->view($this->templatesFolder.'tabs_end');
$this->load->view('web/footer');
/*redirect("/course/new", "location");*/
}else{
$saved = $this->Course_model->saveCourse();
if($saved){
$this->feedback_message->create('Success', 'success');
}else{
$this->feedback_message->create('Error '.$_POST['name'], 'error');
}
redirect('course/');
}
}

To re-populate the form you have to use the set_value('field_name') function in your input field like below:
<input type="text" name="name" value="<?php echo set_value('name'); ?>" />
Return the previous view as:
$this->load->view('view_name',$All_Data_For_View);
Still If you aren't understand then read the CI form validation again.
