WP-Router

You can acccess the router at any point using the $wp_router global

global $wp_router

Defining a simple route is simple, routes consist of a Name, URI and a Closure callback. The URI will be appended to the site url, for example: http://example.com/simple

Basic GET Route

$wp_router->get( array(
	'as'   => 'simpleRoute',
	'uri'  => '/simple',
	'uses' => function()
	{
		return 'Hello World';
	}
) );

Basic POST Route

$wp_router->post( array(
	'as'   => 'simpleRoute',
	'uri'  => '/simple',
	'uses' => function()
	{
		return 'Hello World';
	}
) );

Support for PUT, DELETE and PATCH

$wp_router->put();
$wp_router->delete();
$wp_router->patch();

Using functions, class methods or controllers

$wp_router->get( array(
	'as'   => 'simpleRoute',
	'uri'  => '/simple',
	'uses' => 'my_function'
) );

$wp_router->get( array(
	'as'   => 'simpleRoute',
	'uri'  => '/simple',
	'uses' => array( $this, 'method' )
) ;

$wp_router->get( array(
	'as'   => 'simpleRoute',
	'uri'  => '/simple',
	'uses' => __NAMESPACE__ . '\Controllers\SampleController@method'
) ;

Route Parameters

You can set route parameters in your URI by defining as {param}. These parameters then be accessed by your Closure or Controller as $param

$wp_router->get( array(
	'as'   => 'userProfile',
	'uri'  => '/user/{id}',
	'uses' => function($id)
	{
		return "User: {$id}";
	}
) );

Route Middleware

You set up middleware which runs when your route is accessed before the Closure is run. You can run more than one and are passed as an array.

class Middleware_One extends WP_Middleware {

    public function handle(WP_Request $request)
    {
        if ($request->get('id') == 1)
        {
            return 'No';
        }

        return $this->next($request);
    }
}

$wp_router->get( array(
	'as'   => 'simpleRoute',
	'uri'  => '/simple',
	'middlewares' => array( 'Middleware_One' ),
	'uses' => __NAMESPACE__ . '\Controllers\SampleController@method'
) );

Overall Example

class Middleware_One extends WP_Middleware {

    public function handle(WP_Request $request)
    {
        if ($request->get('id') == 1)
        {
            return 'No';
        }

        return $this->next($request);
    }
}

class Route_Test {

    protected $router;

    public function __construct()
    {
        global $wp_router;

        $this->router  = $wp_router;

        $this->register_routes();
    }

    public function register_protected_routes()
    {
        $this->router->get( array(
            'as'   => 'getTest',
            'uri'  => 'test/{id}',
            'uses' => array( $this, 'get' )
        ) );
    }

    protected function register_routes()
    {
        $this->router->group( array(
            'prefix' => '/protected',
            'middlewares' => array( 'Middleware_One' ),
            'uses' => array( $this, 'register_protected_routes' )
        ) );

        $this->router->post( array(
            'as'   => 'postTest',
            'uri'  => '/test/{id}',
            'uses' => array( $this, 'post' ),
            'prefix' => ''
        ) );

        $this->router->put( array(
            'as'   => 'putTest',
            'uri'  => '/test/{id}',
            'uses' => array( $this, 'put' )
        ) );
    }

    public function get($id, WP_Request $request)
    {
        $all = $request->all();

        return new WP_JSON_Response($all);
    }

    public function post($id)
    {
        return 'POST: The ID is ' . $id;
    }

    public function put($id)
    {
        return 'PUT: The ID is ' . $id;
    }

}
