## Description

Add one or more “lists” to any post. Registered users of your site can then join
or leave the list. Lists can be used for any purpose (event RSVPs, running polls
or surveys, etc.) and can be unobtrusively added to any post type. Optionally, lists
can have a maximum number of users on it that you define, after which any user who
joins the list is automatically added to an overflow “waitlist.”

This plugin also serves the needs of plugin developers who are looking for a simple
way to manage sets of users on a per-post basis. A simple set of public functions
are exposed to other installed plugins that developers can use to get information
about the lists themselves, and the users listed on them.

#### Code examples

After installing and activating this plugin, include it in your own plugin project
as follows:

    ```
    <?php
    /**
     * Plugin Name: My plugin project
     * Plugin URI: http://example.com/
     * Description: Example plugin for playing with WP-Waitlist.
     * Author: Me, myself, and I
     * Version: 1.0
     */

    class My_Plugin {
        private $WP_Waitlist;

        public function __construct () {
            add_action('init', array($this, 'registerDepdencies'));
        }

        public function registerDepdencies () {
            global $WP_Waitlist;
            if (!$WP_Waitlist) {
                // WP-Waitlist is not available, issue an error.
            } else {
                $this->$WP_Waitlist = $WP_Waitlist;
            }
        }

    }

    $My_Plugin = new My_Plugin();
    ```

At that point, you can call WP-Waitlist’s functions in your own plugin as follows:

    ```
    public function myPluginLearnsAboutWaitlists ($post_id) {
        // Get an array of all lists that the author of this post created.
        $lists = $this->WP_Waitlist->getListsForPost($post_id);

        // You can iterate through the lists attached to this post.
        foreach ($lists as $list_name) {
            $list_properties = $this->WP_Waitlist->getListProperties($post_id, $list_name);
            foreach ($list_properties as $property_name => $property_value) {
                print "$property_name is $property_value <br />";
            }

            // You can also learn which users are on the list...
            $user_ids = $this->WP_Waitlist->getListedUsers($post_id, $list_name);
            foreach ($user_ids as $id) {
                $this_wp_user = get_userdata($id); // $this_wp_user is now a WP_User object.
            }

            // ...and which users have been waitlisted (joined after the list reached capacity).
            $waitlisted_users = $this->WP_Waitlist->getWaitlistedUsers($post_id, $list_name);

            // You can also get an array all users who have added themselves to the list, sorted by date.
            $all_user_ids_on_list = $this->WP_Waitlist->getUsersOnList($post_id, $list_name);
        }

    }
    ```
