Session destroing flashdata |
Hi guys, i'm brazilian, and sorry about my english.
Ok, let's go to the problem: I'm trying to make a logoff button, and when a user click in logoff, i call the function logoff: function logoff(){ $this->session->sess_destroy(); $this->session->unset_userdata(array('user_id', 'user_nome', 'user_admin', 'user_logado')); set_msg('logoff', 'Logoff efetuado com sucesso.', 'sucesso'); redirect('usuarios/login'); } but, when i destroy the session, i can't create a new one to display the message that was set in 'set_msg' function. I've two function in my helper to display it: function set_msg($id = 'msgerro', $msg = NULL, $tipo = 'erro'){ $CI =& get_instance(); switch($tipo): case 'erro': $CI->cookies->set_flashdata($id, '<div class="alert-box alert radius">'.$msg.'</div>'); break; case 'sucesso': $CI->session->set_flashdata($id, '<div class="alert-box sucess radius">'.$msg.'</div>'); break; default: $CI->session->set_flashdata($id, '<div class="alert-box radius">'.$msg.'</div>'); break; endswitch; } //Verifica se existe uma mensagem para exibir na tela atual. function get_msg($id, $print = TRUE){ $CI =& get_instance(); $flash = $CI->session->flashdata($id); THAT VALUE WAS COMING NULL BECAUSE OF SESSION DESTROY. var_dump($flash); if(isset($flash)){ if($print){ echo $flash; return TRUE; } else{ return $CI->session->flashdata($id); } } Make sense? Someone have a hint to give me, how to fix this problem? My CI version is 3.0.3 in old versions, people type $this->session->create(); and it's work very well.. Heelp me!
Code: $this->session->sess_destroy(); For this case I would replace it with: Code: $this->session->sess_regenerate(TRUE); // TRUE here destroys the session data. http://www.codeigniter.com/user_guide/li...regenerate
If all you are doing is showing a message that the user successfully logged out, then why not just redirect to a place where the message is displayed. For instance /login?logout=1. By doing that, the user can choose to log back in again, and you can use the logout query parameter to show the logout confirmation.
