WREST (WordPress REST)

WREST - easy to use fluent REST API wrapper for WordPress.

Installation

Requirements

• PHP >= 5.6
• WordPress >= 4.4

You can install wRest in two ways, via composer and manually.

1. Composer Installation

Add dependency in your project (theme/plugin):

composer require arafatkn/wrest

Now add autoload.php in your file if you haven't done already.

require __DIR__ . '/vendor/autoload.php';

2. Manual Installation

Not Available Yet.

Usage

WordPress API needs a namespace, so you have to set a namespace first.

One way is to set a default namespace before creating routes.

wrest()->setNamespace('my-plugin/v1');

wrest()->get('hello', function() {
    return 'Hello world';
});

or you can set namespace for a group of routes.

wrest()->usingNamespace('my-plugin/v1', function($wrest) {
    // You can use both $wrest or wrest() here
    $wrest->get('greeting', function(WP_REST_Request $req) {
        return 'Hello world';
    });
});

Passed callback will get a WP_REST_Request object as a parameter.

wrest()->get('greeting', function(WP_REST_Request $req) {
    return 'Hello world';
});

More Examples

wrest()->get('posts', $callback);
wrest()->post('posts', [$postController, 'store']);
wrest()->put($uri, $callback);
wrest()->patch($uri, $callback);
wrest()->delete($uri, $callback);
wrest()->any($uri, $callback); // All Routes GET, POST, PUT, PATCH, DELETE
wrest()->match(['GET', 'POST'], $uri, $callback);

Permission Management

Passing a capability

wrest()->get('greeting', function() {
    return 'Hello world';
})->permission('manage_options');

Passing a callback

wrest()->get('greeting', function() {
    return 'Hello world';
})->permission(function(WP_REST_Request $req) {
    return is_user_logged_in();
});

Parameters passing

wrest()->get('/posts/{slug}', function(WP_REST_Request $request, $slug) {
    //
})->param('slug', '[A-Za-z]+');

wrest()->get('/user/{id}/{name}', function ($request, $id, $name) {
    //
})->param('id', '[0-9]+')->param('name', '[a-z]+');

wrest()->get('/user/{id}/{name}', function ($request, $id, $name) {
    //
})->param(['id' => '[0-9]+', 'name' => '[a-z]+']);

If you do not pass a regex for a param then [^/]+ will be used as default.

wrest()->get('/posts/{slug}', function(WP_REST_Request $request, $slug) {
    // Also Works. slug will contain all the characters between posts/ and next /.
});

Route Action

Action can be a callback, a class method, a static class method or a non-static class method and can be passed as below.

wrest()->get('posts', function() => {});
wrest()->get('posts', 'getAllPosts'); // getAllPosts is a function.
wrest()->get('posts', 'PostController@getAll'); // getAll is static function.
wrest()->get('pages', [$pageController, 'getAll']); // getAll is non-static function.
wrest()->get('authors', [CommentController::class, 'getAll']); // getAll is static function.

All the functions will get a WP_REST_Request object as a parameter.
