What happens with sessions?? - El Forum - 04-22-2009 [eluser]IEDani[/eluser] Hi, I need to use sessions in my app and I am having problems. First of all I try to use the session library but if you use it the library generate a lot of warnings. The only way to modify it is program in the library, and it can give more troubles. Can I disable the session system of codeIgniter? how? So, I decided use the traditional sessions ($_SESSION['var']) but my app don´t reconize it and tell me that $_SESSION is an undefined var. Can I use the traditional sessions? how? Thanks you so much! Dani What happens with sessions?? - El Forum - 04-22-2009 [eluser]darkhouse[/eluser] What warnings do you get? I use the standard session library and store the session data in the database. I don't get any warnings. What happens with sessions?? - El Forum - 04-22-2009 [eluser]Skuja[/eluser] I believe those where headers already sent warnings. my 2 cents. What happens with sessions?? - El Forum - 04-23-2009 [eluser]IEDani[/eluser] Exactly Skuja, this is the warning (the headers already sent). How can I solve it?? Or how can use the traditional sessions? Thanks,Dani What happens with sessions?? - El Forum - 04-23-2009 [eluser]Dam1an[/eluser] Unless I'm confusing mysdelf with something else, you can't write to $_SESSION after you've outputted to the browser... this may be intentionally calling a view, or having some whitespace somewhere (eg a new line outside of <?php and ?> tags) What happens with sessions?? - El Forum - 04-23-2009 [eluser]Skuja[/eluser] It is not exactly CI sessions fault. Somewhere, somehow in your app you have some ouput before document headers are sent. There could be a bunch of kinds of things to cause this, starting from invalid document encoding to some extra whitespaceses before <?php tags. Please copy your error messages here and i am sure we wil be able to help you more to find exact reason that causes yours. What happens with sessions?? - El Forum - 04-23-2009 [eluser]IEDani[/eluser] Hi, I am searching the error but I don´t find it... ---------------- This is the error: A PHP Error was encountered Severity: Warning Message: Cannot modify header information - headers already sent by (output started at /var/www/vhosts/x.com/httpsdocs/CodeIgniter/system/application/models/acceso_model.php:23) Filename: libraries/Session.php Line Number: 662 ---------------- This is the code of acceso_model.php, the document that sent the headers (¿?): <?php class Acceso_Model extends Model { function Acceso_Model(){ // Call the Model constructor parent::Model(); } function esValido($usuario,$contrasenia){ //compruebo que el usuario existe $sql='SELECT * FROM Usuarios WHERE usuario=?'; $query = $this->db->query($sql,array($usuario)); $acceso=($query->num_rows() > 0); //si el usuario existe compruebo que su clave es correcta if ($acceso){ $row = $query->row(); $acceso= $row->contrasenia == md5($contrasenia); } return $acceso; } } ?> ---------------- This is a piece of the code of acceso.php, that fix the session and call to acceso_model.php ....... $this->load->model("Acceso_Model"); if ($this->Acceso_Model->esValido($usuario,$contrasenia)){ $this->load->library('session'); $datosAcceso = array( 'usuario' => $usuario, 'logado' => TRUE ); $this->session->set_userdata($datosAcceso); ............ -------------------------- I am sure that we can solve it! Thaks you so much! Dani What happens with sessions?? - El Forum - 04-23-2009 [eluser]TheFuzzy0ne[/eluser] You probably have a space after the closing ?> tag. It's recommended you actually remove the last ?> tag for this reason. If you look at the core CodeIgniter files, you'll see that all of those files have the closing ?> tag omitted. What happens with sessions?? - El Forum - 04-23-2009 [eluser]IEDani[/eluser] Exactly!! Thanks you so much, it ´s great have your help! Dani |
