Using Session in CI

Using  Session:

For using Session in CI must have to add this following line:

$this->load->library( ’session’ );

Important Note: If you have to use session for different pages, in that case u have to write this same line each and every time. So, better not to use this line, but play with the CONFIG folder.

• go to the location “http://localhost/PROJECT_FOLDER/system/application/config/“
• open the file “autoload.php”
• than rewrite the variable $autoload['libraries'] =  array( ‘session‘);

After than should have to assign session value like array:

[array]

( ’session_id’    => random hash,

‘ip_address’    => ’string – user IP address’,

‘user_agent’    => ’string – user agent data’,

‘last_activity’ => timestamp )

Retrieving  data from session:

$session_id = $this->session->userdata( ’session_id’ );

Adding Custom Session Data:

$this->session->set_userdata( $array );

Where $array is an associative array containing your new data. Here’s an example:

$sessionArry= array(

‘username’  => ‘Lizee’,

‘email’     => ‘lizee@mysite.com’,

‘logged_in’ => TRUE,

‘usertype’ => ’superAdmin’,

);

$this->session->set_userdata( $sessionArry );

userdata , set_userdata are the library function. So, never and every change those.
