thanks in advanced!
i had same problem in 1 of project.
i see problem in index function , login check status in login function.
you can refer below -
public function index($msg = null){ $this->is_logged_in(); //here i've added status check whether user logged in ['msg'] = $msg; $this->load->view('login_view', $data); } public function login(){ $this->load->model('login_model'); // validate user can login $result = $this->login_model->validate(); //validating user model // verify result if(! $result){ // if user did not validate, show them login page 1 time again $msg = '<font color=red>invalid username and/or password.</font><br />'; $this->index($msg); }else{ $this->redirect_other(); } } //end function login() codeigniter loops redirect html-helper infinity
