codeigniter URL change - php

Question

I am creating eCommerce in Codeigniter. Here is the controller file for registration:
class Register extends CI_Controller {
public function index()
{
$this->load->view('common/header');
$this->load->view('register');
$this->load->view('common/footer');
}
public function home(){
$this->load->view('common/header');
$this->load->view('common/slider');
$this->load->view('home');
$this->load->view('common/footer');
}
public function signup(){
$username = $this->input->post("username");
$password = $this->input->post("password");
$email = $this->input->post("email");
$this->form_validation->set_rules('username','User Name','required|is_unique[user.name]|min_length[4]');
$this->form_validation->set_rules('password','Password','required|min_length[5]');
$this->form_validation->set_rules('email','Email address','required|valid_email');
$this->form_validation->set_error_delimiters('<div class="text-danger">', '</div>');
if($this->form_validation->run() == true){
$this->load->model('register_model');
if($this->register_model->register_user($username,$password,$email)){
$this->home();
}else{
$this->index();
}
}else{
$this->index();
}
}
}
On form submit the page is redirecting to the home page but the URL on the browser is (http://localhost:8080/codignitor_projects/shophere/register/signup) But I want to change the URL to this (http://localhost:8080/codignitor_projects/shophere/)

I got your problem. I don't know your CI version. I hope you are using the latest one and I am also giving my answer according to the latest version CI-4.
Please Write
return redirect()->to('index');
or
return $this->response->redirect(base_url('YourControllerName/index'));
instead of
$this->index();
To clearify this problem I would like to give you an example. Let, I have a Test controller and there are two functions such as abc() and def()
class Test extends Controller
{
function abc()
{
echo "Hi ! I am ABC";
}
function def()
{
$this->abc();//URL will be: http://localhost/your_project_name/public/test/def
//return redirect()->to('abc'); //URL will be: http://localhost/your_project_name/public/test/abc
//return $this->response->redirect(base_url('Test/abc')); //URL will be:http://localhost/your_project_name/public/Test/abc
}
}
There are three lines inside the def() function that give you the same result but the URL from first one to others will be different which is commented.
