WP Session Manager
==================

Prototype session management for WordPress.

Description
-----------

Adds `$_SESSION`-like functionality to WordPress.

Every visitor, logged in or not, will be issued an instance of `WP_Session`.  Their instance will be identified by an ID
stored in the `_wp_session` cookie.  Typically, session data will be stored in a WordPress transient, but if your
installation has a caching system in-place (i.e. memcached), the session data might be stored in memory.

This provides plugin and theme authors the ability to use WordPress-managed session variables without having to use the
standard PHP `$_SESSION` superglobal.

Installation
------------

**Manual Installation**

1. Upload the entire `/wp-session-manager` folder to the `/wp-content/plugins/` directory.
1. Activate the plugin through the 'Plugins' menu in WordPress.
1. Use `WP_Session::get_instance();` in your code.

Frequently Asked Questions
--------------------------

**How do I add session variables?**

First, make a reference to the WP_Session instance.  Then, use it like an associative array, just like `$_SESSION`:

`$wp_session = WP_Session::get_instance();
$wp_session['user_name'] = 'User Name';                            // A string
$wp_session['user_contact'] = array( 'email' => 'user@name.com' ); // An array
$wp_session['user_obj'] = new WP_User( 1 );                        // An object`

**How long do session variables live?**

By default, session variables will live for 24 minutes from the last time they were accessed - either read or write.

This value can be changed by using the `wp_session_expiration` filter:

`add_filter( 'wp_session_expiration', function() { return 60 * 60; } ); // Set expiration to 1 hour`
