How to update certain session

Hi,  I have problem with codeigniter session. I want update certain session. Example I store my email, username, and user_lvl in session. If I change/update email in user profile and I click submit button. The new email will update in session.

This is how I store my session in codeigniter:

PHP Code:

$setSession= array(
        'username' => 'admin',
        'email'    => '[email protected]',
        'user_lvl' => 1,
);    
$this->session->set_userdata('logged_in', $setSession); 


Note: I just want update email in session only.

This is me. JK not me.

@falcon812311,

Here is the CI documentation on session variables: https://codeigniter.com/user_guide/libra...sion-class

It shows how to update a session variable. All that is necessary is placing it at the right location in your code to update.

Very easy.

PHP Code:

$_SESSION['email'] = "[email protected]"; 


This will also work.

PHP Code:

$this->session->email =  "[email protected]"; 


The first is slightly more efficient and is what the documentation recommends. (See second paragraph of the linked documentation section.)
