Setting expire date to Session data

[eluser]xerosis[/eluser]
Hi,
I have set the session for users to stay for 2 hours.
But here is my problem, I create a custom session data:

Code:

$this->session->set_userdata('some_name', 'some_value');

I want this to only be active for 3 minutes and then get expired.

Is it possible to assign it in the above code rather than having to do a manual check with time(); and deleting it if it is over 3 minutes every time he/she opens/refresh the page?

Thanks.

You will either have to extend the Session library by a large amount or set a cookie yourself.

But keep in mind:
Standard cookies without a database backend can just contain 4 KB of data.

In case that the information in your cookie is not security critical, this should be sufficient.

You can create your encryption for your cookies to protect them if need be.

Hey Guys, isn't it true that you can set expire session time changing this?

Code:

$config['sess_expiration'] = 7200;

in the /application/config/config.php file

Sorry if I misunderstood the question :-)

You could always just put a timestamp and store it in the session with the other data, and when you retrieve it check to see that it is less than 3 minutes old. If older, remove it, if not, use it.

Yes, but that is a global setting. If you have a special case where it needs to be lower for one instance, you don't have a way to change it.

Thanks for the explanation, I didn't understand the first time I read the question.

Doing this

Code:

$this->session->set_userdata('some_name', 'some_value');

//RE-SETTING THE "sess_expiration" AFTER IT SETS THE set_userdata()
$this->config->set_item('sess_expiration', 180);

Isn't this a solution? Please, correct me if i'm wrong.

No because on the very next page load it will go back to what is set in the config, undoing anything you dynamically set.

I didn't thought on that, even much to learn :lol:

Thanks
