Codeigniter会话在其他页面中不可见

Question

Hi friends I am using codeingter default session library. I have created normal login and facebook login for my web application using this library.

Normal login was working properly with this library, when I tried to do the same with fb login , I am able to see the session variables only in the login page. When I go to different pages of the website session variables are not visible.

FB login:- print_r($this->session->all_userdata()); for login page is giving me the following array

Array ( [session_id] => 18d8f5e5f8504289d848a137e6d8587b [ip_address] => *** [user_agent] => Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0 [last_activity] => 1425530911 [user_data] => [user_id] => 2262 [user_email] => **** [logged_in] => 1 [facebook_login] => 1 [admin] => [logout] => https://www.facebook.com/logout.php?next= *****&access_token=CAANoqwioFoQBACkl2krguKonH3nDamlowXcZCxhqhZAMa1ncOgazFdGXmkSB1QjnpZCweDa1MrXcWK1ZAgUUDHh7Xi7OEJSoJKvt8VXpWYeb3qfcz0mYXmzcLJqZCTFh4PheYD84zGq5u7Q1YQLINS1I7t6KU4EwlGxVMsZBKYjgFAt8tZA5CqSYQ168kvC329TqPZBF2ZAS8j6HfVFcHWsvO )

where as for other pages the array is null

Please help me to resolve this issue.

This is the model which I am using for fb login

 if($query->num_rows()>0)
>                 { 
>                         foreach($query->result() as $rows)
>                         {
> 
>                                 //add all data to session
>                                 $newdata = array(
>                                                 'user_id'  => $rows->id,
>                                                 'user_email'    => $rows->email,
>                                                 'logged_in'  => TRUE,
>                                                 'facebook_login' => TRUE,
>                                                 'admin'=>False,
>                                                 'logout' => $logout
>                                                 );
>                         }
> 
> 
>                         $this->session->set_userdata($newdata);
> 
>                         $message = $this->session->all_userdata();

Answer 1

If you are using CI 3 all_userdata() is DEPRECATED, you can use userdata() with no parameters.

If the problem remain or your not using CI 3, you can use Native Session library, because CI original session library has some problem.
