how can a page redirect users back to previous page if they try to access the page via url?

codeigniter redirect http-referer ion-auth

In the page that you want to go back to you can do:

$this->session->set_userdata('referred_from', current_url());

Then redirect back to that page

$referred_from = $this->session->userdata('referred_from');redirect($referred_from, 'refresh');

codeigniter redirect http-referer ion-auth

Try this :

$this->load->library('user_agent');redirect($this->agent->referrer());

else

Use SESSION for login and logout. if session exist block login page else allow login page using if statement.

codeigniter redirect http-referer ion-auth

I'm doing this way.

redirect($_SERVER['HTTP_REFERER']);
