php - codeigniter hook to check user is logged in -

i trying add validation hook (checking user/company active) , managed working fine tinkering...

i trying have been doing in each class > function (or __construct) , basic check user logged in using session data 'loginuser' set boolean...

i trying use keep getting too_many_redirects. it's same code use in either __construct or each public function , works there perfect (except changed non object)...

    function logged_in() {      $ci =& get_instance();      if(!$ci->session->userdata('loginuser')) {         redirect('account/login');     } } 

i @ loss why wont work in hook called 'post_controller_constructor'. overlooking simple have been going around in circles hours , google/so searchers giving nothing of use. basic thing too...

answer: playing @ home was:

    function logged_in() {      $ci =& get_instance();      if(!$ci->session->userdata('loginuser')) {         if (uri_string() != 'account/login' && uri_string() != 'login' && uri_string() != 'account/register'){              $ci->session->set_flashdata('flasherror', 'please login continue');             redirect('account/login');         }     }  } 

your code doing want, there's bit of oversight.

you need check if current route login page before kind of redirect.

i imagine when had check in controllers constructor before, didn't put in account controller.

if (user not logged in) {     if (current route not login page) {         redirect user login page     } }
