The Story Behind The Topic
We Are Going Mobile
How To make your website mobile ready?
Native Apps VS Mobile Web
Native Apps VS Mobile
Go native when Need to produce the best user
experience — fast and fluidPeople are going to use it quite often
( daily basis )A lot of users request for itCustomers really want an app
Go Native
What does it Means
You need to communicate with another developer
Need to build an API that the developer can use
So you need to understand what a mobile developer wants
Need to build additional fields in WordPress for information that the mobile app can use
The API
How to build an API out of WordPress?
Options
XML-RPC API-Plugins
Using XML-RPC as an API
Why XML-RPC Won’t work
It is not designed as a data fetching API XML-RPC uses about 4 times the number
of bytes compared to plain XML Need a lot of code on the app side In the end the size of requests/responses
do matter
Using Plugins for creating API
Available Plugins
JSON API WP RESTful WP API
JSON API (Plugin)
Simple, consistent external interface Stable, understandable internal
implementation Enable new types of extensions for
WordPress
What is JSON?
JavaScript Object Notation Alternative to XML text-based open standard designed
for human-readable data interchange Represents simple data structures and
associative arrays, called objects
JSON Example
myObject = {
"first": "John",
"last": "Doe",
"age": 39,
"sex": "M",
"salary": 70000,
"registered": true,
"interests": [ "Reading", "Mountain Biking", "Hacking" ] }
JSON API Interface
Built in Controllers
Core Controller Post Controller Respond Controller
Core controller methods
Info get_recent_posts
get_post get_page get_date_posts get_category_pos
ts
get_tag_posts get_author_posts
get_search_results
get_date_index get_category_index
get_tag_index get_author_index get_page_index get_nonce
Post & Respond controller methods
create_post submit_comment
http://nikhilvishnu.com/api/get_recent_posts/
Developing JSON API controllers Create a controller file (hello.php) inside wp-
content/plugins/json-api/controllers
<?php class JSON_API_Hello_Controller {
public function hello_world() {
return array( "message" => "Hello, world" );
} }
?>
Developing JSON API controllers
public function hello_person() {
global $json_api; $name = $json_api->query->name; return array(
"message" => "Hello, $name." );
}
External controllers
function add_hello_controller($controllers) { $controllers[] = 'hello'; return $controllers;
}
add_filter('json_api_controllers', 'add_hello_controller');
function set_hello_controller_path() { return "/path/to/theme/hello.php";
}
add_filter('json_api_hello_controller_path','set_hello_controller_path');
Important Points
Only return data that is needed Don’t change the feed without notifying
the app developer A call shouldn’t take to long, speed is
everything Cache the data if possible

Ways To Improve
Add consumer key/secret Admin page for customizing response
(remove categories)
More Plugins
