copied!<p>I do this by extending my controller and I check in constructor if person is logged in or not, if person is logged in I save to the session current URL, and redirect person to the login page (if same constructor is applied (controller one) I make exception to not save current URL to the session) after logging in I call redirect function to the session variable.</p> <p>How to extend your controller is done here <a href="http://philsturgeon.co.uk/blog/2010/02/CodeIgniter-Base-Classes-Keeping-it-DRY" rel="nofollow">http://philsturgeon.co.uk/blog/2010/02/CodeIgniter-Base-Classes-Keeping-it-DRY</a> </p> <p>note that when your controller is extended you use <code>$this->data['variable_sent_to_view']</code> and you can omit second parameter of <code>$this->load->view()</code></p> <p>here is some example code assuming you know how your login controller works</p> <pre><code><?php if (!defined('BASEPATH')) exit('No direct script access allowed'); class MY_Controller extends CI_Controller { function __construct() { parent::__construct(); $this->output->enable_profiler(FALSE); if ($refer = $this->session->flashdata('refer')) { $this->data['refer_page'] = $refer; // $this->data['refer_page'] is variable that you are interested in unset($refer); } else { $this->data['refer_page'] = base_url(); //default refer_page } //check if user is NOT logged in if (!$logged_in) { $this->_setRefer(); //this is private function } // else dont care about it } private function _setRefer() { $invalid_method = array('search', 'login'); // if method is 'search' or 'login' url will not save in session (it will stay same as was before) $valid_refer = TRUE; if (in_array($this->router->method, $invalid_method)) { $valid_refer = FALSE; } if (!(count($_POST) > 0) && $valid_refer === TRUE && !$this->input->is_ajax_request()) { $this->session->set_flashdata('refer', current_url()); } else { $this->session->set_flashdata('refer', $this->data['refer_page']); } } } </code></pre> <p>now in after succesful login redirect to $this->data['refer_page'], but note that login controller must by extended by MY_Controller.</p> <p>this script also takes care about what happens if user made mistake and inserted wrong password (page will reload but "old" url stays)</p>
