This section describes Leafiny session management.

• Context
• Initialization
• Store data

Context

A session context is a data storage in the session that can contain arbitrary data.

The default frontend context is named frontend, and the admin context is named backend.

Initialization

The frontend session is initialized in the Frontend module, with an observer:

/** modules/Frontend/etc/config.php **/

'events' => [
    'frontend_page_pre_process' => [
        /* ... */
        'frontend_page_init_session' => 200,
    ],
],

'observer' => [
    /* ... */
    'frontend_page_init_session' => [
        'class' => Frontend_Observer_InitSession::class,
    ],
],

If you do not need a session (static site, single page…), delete this observer.

Store data

Add data

$session = App::getSession(Core_Template_Abstract::CONTEXT_DEFAULT); // frontend

if ($session) {
    $session->set('key', $data);
}

Retrieve data

$session = App::getSession(Core_Template_Abstract::CONTEXT_DEFAULT); // frontend

if ($session) {
    $data = $session->get('key');
}

Delete data

$session = App::getSession(Core_Template_Abstract::CONTEXT_DEFAULT); // frontend

if ($session) {
    $session->destroy('key');
}
