CI Not create session - codeigniter

$veri = array("uye_kadi" => $this->input->post('kadi'), 'oturum' => TRUE);
$this->session->set_userdata($veri);

First make sure that you have included session library
either from autoload config file:
$autoload['libraries'] = array('session');
or from controller:
$this->load->library('session');
and then
replace your code with :
$veri = array("uye_kadi" => $this->input->post('kadi'), 'oturum' => TRUE);
$this->session->set_userdata('sess_var_name',$veri);
echo $this->session->userdata('sess_var_name');
Array with can be used as:
$ar = array('user_id'=>900,
'username'=>'John Doe');
$this->session->set_userdata('user_details',$ar);
$this->session->userdata('user_details','user_id'); //Return 900;
hope it will help!

PHP Codeigniter 3.1.10: Unable to update session data

Happen to be stuck since almost a day. Scoured in google searching as to why this isn't working as expected, and also couple of answered questions in stackoverflow, but couldn't figure out as to why it's not working.
Basically i am setting session data during login, like
foreach($response as $item) {
$sess_array = array(
'user_id' => $item->id,
'photo' => $item->user_pic,
);
}
// Create session
$this->session->set_userdata('logged_in', $sess_array);
And now I am attempting to update a particular variable named 'photo'.
$this->session->set_userdata('photo', $new_name);
And when I try to display the value of the session variable 'photo' in my view, it still shows the old value and not the updated value.
Below are the entries from config.php
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = BASEPATH . 'cache/sessions/';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = TRUE;
Codeigniter version 3.1.10
OS Windows 10
Please help.
First of all just check in you autoload.php did you load the session library or not.
or else load session library in your controller. $this->load->library('session');
foreach($response as $item) { // looping your obj $response
$sess_array = array( // set an array
'user_id' => $item->id,
'photo' => $item->user_pic,
);
}
print_r($sess_array); you will get the last element of you $response obj here.
// Create session
$this->session->set_userdata('logged_in', $sess_array); // here you are setting the last obj of $response in you session logged_in
`$this->session->set_userdata('photo', $new_name);` // here you store an variable $new_name in session `photo`
redirect from your controller current function to new function after setting the session.
for example.
class session extend CI_Controller{
function set_session(){
$new_name = 'xyz';
$this->session->set_userdata('photo', $new_name);
return redirect('session/get_session');
}
function get_session(){
$this->load->view('sample');
}
}
In your view sample.php
<body><h1>
<?php
echo $this->session->userdata('photo');
// here you got out put 'xyz'
?>
</h1></body>
Hope you can find the issue where you go wrong.

How to set_userdata after session_destroy in codeginiter?

For some reasons I need to destroy all sessions in a controller in my codeigniter and set new one immediately after that. but as you can see in the following example, seems it is not working in Codeigniter version 3.1.9 or my usage is in wrong way.
I have this controller in my Codeigniter:
<?php
class Test extends CI_Controller {
public function index()
{
$this->load->library('session');
$this->session->sess_destroy();
$session_data = array (
'key_1' => 'value_1',
'key_2' => 'value_2',
'key_3' => 3
);
$this->session->set_userdata($session_data);
$this->session->set_userdata('key_4', 4);
print_r($_SESSION);
}
public function next()
{
$this->load->library('session');
print_r($this->session->all_userdata());
}
}
When I open MYDOMAIN.COM/test, the output is like this:
Array ( [__ci_last_regenerate] => 1545508348 [key_1] => value_1 [key_2] => value_2 [key_3] => 3 [key_4] => 4 )
but immediately after that, if I open MYDOMAIN.COM/test/next, the output is empty like this:
Array ( [__ci_last_regenerate] => 1545509049 )
In the config.php the session configuration is like bellow (please note the ci_sessions is a writable folder):
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 60*60*1;
$config['sess_save_path'] = APPPATH . 'ci_sessions/';
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;
Could you please guide me what is wrong?
Consider for a moment what you are doing.
First you just start the session by calling $this->load->library('session').
Then you immediately stop the session with $this->session->sess_destroy();.
There are multiple problems with what you are trying. Read this to learn more.
You would be much better off simply clearing $_SESSION and then adding the new data to it.
public function index()
{
$this->load->library('session');
// if you want a new session id uncomment the next line, needs to happen before you clear $_SESSION
//session_regenerate_id();
$_SESSION = array();
// if you uncommented earlier then uncomment the next too
//$_SESSION['__ci_last_regenerate'] = time();
$session_data = array (
'key_1' => 'value_1',
'key_2' => 'value_2',
'key_3' => 3
);
$this->session->set_userdata($session_data);
$this->session->set_userdata('key_4', 4);
print_r($_SESSION);
}
With CodeIgniter > v3.0.0 you can set $_SESSION directly. The documentation actually recommends doing it that way. With that in mind the line
$this->session->set_userdata('key_4', 4);
could (should) be written
$_SESSION['key_4'] = 4;
set_userdata() is useful for quickly setting a lot of $_SESSION key/values quickly though.
That said, the following seems less abstract than the earlier code to me. If nothing else, it uses a teeny-tiny bit less memory and avoids a function call.
$_SESSION = array();
$_SESSION['key_1'] = 'value_1';
$_SESSION['key_2'] = 'value_2';
$_SESSION['key_3'] = 'value_3';
$_SESSION['key_4'] = 'value_4';
$_SESSION['__ci_last_regenerate'] = time();
Sorry, I sometimes cannot stop myself from going into lecture mode.
Use:
$this->session->sess_regenerate(true);
Instead of:
$this->session->sess_destroy();

why in Codeigniter my session lost in other pages?

it's first time I use Codeigniter 3.x. after authentication for login I set session data in Login_model.php:
$data_session = array(
'PersonId' => $PersonId,
'PersonEmail' => trim($PersonEmail),
'PersonName' => trim($PersonName),
'PersonFamily' => trim($PersonFamily),
'Login' => true);
$this->session->set_userdata($data_session);
before redirect I have access to my session data by :
print_r($this->session->userdata());
Array([__ci_last_regenerate] => 1510383844 [PersonId] => 129[PersonEmail]=> h#q.com [PersonName] => PersonName [PersonFamily] => PersonFamily [Login] => 1)
but after redirect my session data is something like this:
Array( [__ci_last_regenerate] => 1510384212)
also my setting in config.php is:
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'east';
$config['sess_expiration'] = 7200;
//$config['sess_save_path'] = sys_get_temp_dir();
$config['sess_save_path'] = 'ci_sessions';
$config['sess_match_ip'] = TRUE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;
//------------------
$config['cookie_prefix'] = '';
$config['cookie_domain'] = 'domain/admin/';
$config['cookie_path'] = '/';
$config['cookie_secure'] = FALSE;
$config['cookie_httponly'] = FALSE;
I have reviewed a lot of things in this regard. but I still have not gotten a good result.
when using
$config['sess_driver'] = 'files';
then $config['sess_save_path'] must be set to the absolute path of the folder where session files are stored.
With this folder structure
webroot/
application/
sessions/
system/
...etc/
Then
`$config['sess_save_path'] = FCPATH."sessions/";`
will work perfectly.
Folder write permissions must be set appropriately.
EDIT
You should try setting $config['cookie_domain'] = ''; (an empty string) and if that does not work try $config['cookie_domain'] = '.your-domain.com';
The following controller will allow you to test if sessions are working correctly. Create a file named Test_sessions.php in your controllers folder.
Use this code.
<?php
/**
* This class is useful for testing the configuration of the CodeIgniter "session" library.
* It works only for CodeIgniter versions >= 3.0.0
*
* If "session" is properly configured then each time you ask a browser for this page
* the display will alternate between "No session data" and the value of $this->sess_message.
*/
defined('BASEPATH') OR exit('No direct script access allowed');
class Test_sessions extends CI_Controller
{
/**
* #var string So you can define your own message to be displayed.
*/
public $sess_message;
function __construct()
{
parent::__construct();
// The next line can be commented out if 'session' is autoloaded - or not, doesn't matter.
$this->load->library('session');
$this->sess_message = "We got session data!";
}
public function index()
{
echo date("F j, Y, g:i:s a")."<br>"; //so you can tell the page actually does refresh
if($this->session->testing)
{
echo $this->session->testing;
unset($_SESSION['testing']);
}
else
{
echo "No session data";
$_SESSION['testing'] = $this->sess_message;
}
}
}
Browse to http://yoursite.com/test_sessions. If sessions are properly configured, every time you refresh the page it will alternate between the two messages.
I solved my problem by change my config to:
$config['sess_driver'] = 'files';$config['sess_cookie_name'] = 'ci_session';$config['sess_expiration'] = 86400;$config['sess_save_path'] = FCPATH.'sessions/';$config['sess_match_ip'] = FALSE;$config['sess_time_to_update'] = 3600;$config['sess_regenerate_destroy'] = TRUE;$config['cookie_prefix'] = '';$config['cookie_domain'] = '';$config['cookie_path'] = '/';$config['cookie_secure'] = FALSE;$config['cookie_httponly'] = FALSE;

redirect uri segment after delete

I created a project , I have a question about the direct url segment ...
For example:
this my URL
http://10.88.25.131/instrumentdev/instrument/instrument/detail/CT-BSC-001
when I want delete the data and to direct to the url such as the example above
this my controllers
public function detail(){
$id = $this->uri->segment(4);
$data = array(
'detail'=>$this->mcrud->get_detail($id),
'lihat' =>$this->mcrud->lihat_komentar($id),
'isi' =>'instrument/read_views');
$this->load->view('layout/wrapper', $data);
}
function deletecom() {
$u = $this->uri->segment(4);
$this->mcrud->deletecomment($u);
redirect('???**this my problem**???');
}
Use session
$newdata = array(
'data' => $u
);
$this->session->set_userdata($newdata);
redirect('controller/method');
then in next method
$u = $this->session->userdata('data');
Use
$this->load->helper('url');/*if not already*/
redirect(base_url('controller/method/parametersIfAny'));
TRY this :
function deletecom() {
echo $this->uri->segment(4);die(); //what does this print ??
$u = $this->uri->segment(4);
$this->mcrud->deletecomment($u);
redirect(base_url('instrument/instrument/detail/'.$u));
}

Can't use session variable in routes.php file in codeigniter?

I am use following code to retrieve the session variable in routes.php
if($this->db_session->userdata('request_url')!="")
{
$route['user/(:any)'] = "search_user_name/redirect_url/".$_SESSION['request_url'];
$this->db_session->unset_userdata('request_url');
}
else {
$route['user/(:any)'] = "search_user_name/index/$1";
}
the session variable would be set into template/header.php
$this->db_session->set_userdata('request_url', $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]);
You can not use db_session in routes.php because routes.php is parsed before db_session is loaded.
Maybe you should create a base controller and redirect from the constructor of the base controller.
Correct me if iam wrong.
You can use hooks.
Codeigniter user guide hooks
You can use database in routes and put your routes url in database.
Here is an example:
require_once( BASEPATH .'database/DB'. EXT );
$db =& DB();
$table2 = $db->dbprefix.'lang';
$query2 = $db->get( $table2 );
$result2 = $query2->result();
foreach( $result2 as $row )
{
$fields = $db->list_fields($table2);
$findme = 'code';
foreach($fields as $field):
$pos = strpos($field, $findme);
if($pos !== false and $row->$field != ''):
$route[''.$row->$field.''] = 'main/setlang/$1';
endif;
endforeach;
}
