Extends the JSON API Plugin to allow RESTful user registration, authentication and many other User Meta, BuddyPress functions. A Pro version is also available.

==Description==

JSON API User extends the JSON API Plugin with a new Controller to allow RESTful user registration, authentication, password reset, RESTful Facebook Login, RESTful User Meta and BuddyPress xProfile get and update methods. This plugin is for WordPress/Mobile app developers who want to use WordPress as mobile app data backend.

JSON API Plugin, that is required, was closed on August 7, 2019 from WordPress repository. You can download JSON API Plugin from https://github.com/PI-Media/json-api until it is republished and available on WordPress.

Features include:

• Generate Auth Cookie for user authentication
• Validate Auth Cookie
• RESTful User Registration
• RESTful Facebook Login/Registration with valid access_token
• RESTful BuddyPress xProfile fields update
• Get User Meta and xProfile fields
• Update User Meta and xProfile fields
• Delete User Meta
• Password Reset
• Get Avatar
• Get User Info
• Post Comment

The plugin was created for mobile apps integration with the web app using WordPress as backend for all the data. WordPress helped in putting together the web app quickly and then Mobile iOS and Android apps were integrated via this plugin. There were some app specific customized methods which are not included but rest have been made generic for community usage.

My other JSON API Auth plugin has also been integrated with this plugin from version 1.1 because most endpoints required user authentication via cookie for data update.

Pro Version - JSON API User Plus

A pro version of this plugin, JSON API User Plus, is available here http://www.parorrey.com/solutions/json-api-user-plus/ that supports BuddyPress Messages component, BuddyPress avatar upload, BuddyPress Extended Profile, BuddyPress Groups, BuddyPress Friends, BuddyPress Activity, BuddyPress Notifications, BuddyPres Settings and other BuddyPress related functions to integrate BuddyPress features in your mobile app via REST api.

JSON API User Plus includes API key which protects and restricts the endpoint calls. This key can be updated from Settings > User Plus options page. Your app must include this key with every call to get the data from REST API. Please see documentation for calling endpoints examples for 'JSON API User Plus'.

• There are following methods available: register, get_avatar, get_userinfo, retrieve_password, validate_auth_cookie, generate_auth_cookie, get_currentuserinfo, get_user_meta, update_user_meta, delete_user_meta, xprofile, xprofile_update, fb_connect

• nonce can be created by calling if you are registering user. http://localhost/api/get_nonce/?controller=user&method=register

• You can then use 'nonce' value to register user.

• Always use POST method and not GET method to submit data, following url examples of GET method are only for demonstration purposes.

= Method: info =

http://localhost/api/user/info/

This returns plugin version.

= Method: register =

http://localhost/api/user/register/?username=john&email=john@domain.com&nonce=8bdfeb4e16&display_name=John&notify=both

To register user & get valid cookie for 100 seconds: http://localhost/api/user/register/?username=john&email=john@domain.com&display_name=John&notify=both&seconds=100

Optional fields: 'user_pass', 'user_nicename', 'user_url', 'nickname', 'first_name', 'last_name', 'description', 'rich_editing', 'user_registered', 'jabber', 'aim', 'yim', 'comment_shortcuts', 'admin_color', 'use_ssl', 'show_admin_bar_front'.

Please make sure you provide valid values that these fields expect in correct format.

To disbale registration email notification to user:

http://localhost/api/user/register/?username=john&email=john@domain.com&nonce=8bdfeb4e16&display_name=John&notify=no

To register with user provided password:

http://localhost/api/user/register/?username=john&email=john@domain.com&nonce=8bdfeb4e16&display_name=John&notify=both&user_pass=YOUR-PASSWORD

To add custom fields for user profile, send 'custom_fields' named associative array, populated with standard 'meta_key' as index and 'meta_value' as its value. For example, you need to add address and phone for any user, populate custom_fields[address] index with address value and custom_fields[phone] with hpone value.

You can add any number of custom fields. These are stored as meta_key and meta_value in user_meta WordPress table. You can access these values in WordPress using get_user_meta() fucntion.

You can also get these values with get_user_meta endpoint, see below this endpoint documentation.

= Method: fb_connect =

It needs valid 'access_token' var.

http://localhost/api/user/fb_connect/?access_token=CAACEdEose0cBADLKmcHWOZCnW4RGU8emG

Provide valid access_token with email extended permission. To generate test access_token, try this tool https://developers.facebook.com/tools/explorer/ and select the app from above drop down that you want to get access_token (You must have joined that app already with email permission to generate access_token) for and then select email from the fields. By default, only 'id' and 'name' are added but you need to include 'email' for user identification.

You will have to first allow extended permission for email in the app joining screen. Please note that above tool is only for testing, you generate valid access_token using the Graph API in your app. You should know Facebook Graph API to use this endpoint.
