flashdata won't work with redirects

flashdata won't work with redirects even if keep_flashdata is used. Why?

this is the main view class:

public function index()
   // this end up with an empty string like "message ="
   die('message = '.$this->session->flashdata('message'));

public function activate()
   $this->session->flashdata('message', 'Activated!');
   redirect(''); // this will redirect to the index method

Why not working?! I'm using db for storing sessions.
here's my config:

$config['sess_cookie_name']  = 'mysamplesess';
$config['sess_expiration']  = 0;
$config['sess_expire_on_close'] = FALSE;
$config['sess_encrypt_cookie'] = FALSE;
$config['sess_use_database'] = TRUE;
$config['sess_table_name']  = 'sessions';
$config['sess_match_ip']  = FALSE;
$config['sess_match_useragent'] = FALSE;
$config['sess_time_to_update'] = 300;

use set_flashdata()
$this->session->set_flashdata('item', 'value');

[quote author="TWP Marketing" date="1343323633"]use set_flashdata()
$this->session->set_flashdata('item', 'value');

Sorry, my mistake. I was using "set_flashdata". I figured what was the problem. I've been testing the project on my localhost server, but the db i was using for session storing was on a remote server with a pretty shitty connection (3-4 sec to get mysqli connected).
So as far as i'm aware now there two solutions:
- do not use remote databases for session storage, use a local one (same sever)
- use cookies only for sessions

dunno why, will look up the "core" code to investigate that "bug" or whatever.

I certainly agree with avoiding the use of remote servers for db access.
There are some situations where it can't be done any other way, but I don't like putting my sites at the mercy of more than one server.
Hope your problem is resolved.

Hi there,

my experience with flashdata :
when i did my first CodeIgniter project years ago flashdata worked fine. Just as i thought it was intended, and i used it a lot.

Quite some time ago it stopped working correctly and the data always displayed with delay, just one request too late.

I did some research and tried several "solutions", but none of them worked.

So i would suggest: dont bother and use userdata instead.
If you unset the userdata right after passing it to a view, it works exactly as flashdata did before.

Its a pity though, and if someone could come up with why flasdata is messed up / delayed: Please tell us =).

Best Regards,

sorry, overlooked that you solved your problem and it was a different one
