Protected function for calling WP REST API plugin

CakePHP function for calling WP-API .md

1. Install the json rest api wordpress plugin.

2. Include the following function in app/Controller/AppController.php in your CakePHP instalation.

   	protected function _wpAPI($method='get', $url='/', $data=null)
   	{
   		App::uses('HttpSocket', 'Network/Http');
   		$http = new HttpSocket();
   		
   		$http->configAuth('Basic', 'admin', 'password');
   		$wpBase = 'http://your-wordpress-instalation.com/?json_route=';
   		
   		$request = $http->{$method}(
   			$wpBase.$url,
   			$data == null ? null : json_encode($data),
   			array('header'=>array('Content-Type'=>'application/json'))
   		);
   		$results = json_decode($request->body, true);
   		$results['error'] = substr($request->code, 0, 1) != 2;
   		return $results;
   	}

3. Replace http://your-wordpress-instalation.com with the url of your wordpress installation, admin with your wordpress username and password with your wordpress password.

4. Now you can use this function like this:

   	$newPost = array(
   		'status'		=> 'draft',
   		'type'			=> 'post',
   		'title'			=> 'the title of this new post',
   		'name'			=> 'the-slug-for-url',
   		'content_raw'		=> 'Here is the content for your new post.',
   		'post_meta'		=> array(
   			array(
   				'key' => 'custom_field',
   				'value' => 'some randoom value for new meta custom field'
   			)
   		)
   	);
   	$response = $this->_wpAPI('post', '/posts', $newPost);
   	if ($response['error'])
   	{
   		echo "Error: {$response[0]['message']}<br/>\n";
   	} else {
   		echo "Posted !<br/>\n";
   		echo "New post ID: {$response['ID']}<br/>\n";
   		echo "New post title: {$response['title']}<br/>\n";
   		echo "New post slug: {$response['slug']}<br/>\n";
   		echo "New post content: {$response['content']}<br/>\n";
   		echo "New post link: {$response['link']}<br/>\n";
   		// docs here: http://wp-api.org/#posts_create-a-post_input
   	}
