Remove unnecessary fields from json response

Resolved

(@soulcyber)

I want retrieve the last posts using, get_recent_post

http://mydomain.com/api/get_recent_posts/

Everything works fine, but i want call this api from my Android application and i want minimize the data sent by the server.

the response format is the following:

"status":"ok",
"count":5,
"count_total":5,
"pages":1,
"posts":[]

and each post has the following fields :

"id":21,
"type":"post",
"slug":"articolo-prova-3",
"url":"http://mydomain.com/index.php/2014/02/17/articolo-prova-3/",
"status":"publish",
"title":"Articolo prova 3",
"title_plain":"Articolo prova 3",
"content":"",
"excerpt":"",
"date":"2014-02-17 16:00:12",
"modified":"2014-02-17 16:12:04",
"categories":[],
"tags":{},
"author":{},
"comments":{},
"attachments":[],
"comment_count":0,
"comment_status":"open",
"thumbnail":"http://mydomain.com/wp-content/uploads/2014/02/20100204104618Terminator-150x150.jpg",
"custom_fields":{},
"thumbnail_size":"thumbnail",
"thumbnail_images":{}

now i want lightweight the response removing some of this field/arrays

i’m trying to modify the core api without success, i think it’s easy but not enough for a PHP noob like me 😀

public function get_posts() {
    global $json_api;
    $url = parse_url($_SERVER['REQUEST_URI']);
    $defaults = array(
      'ignore_sticky_posts' => true
    );
    $query = wp_parse_args($url['query']);
    unset($query['json']);
    unset($query['post_status']);
    $query = array_merge($defaults, $query);
    $posts = $json_api->introspector->get_posts($query);

    foreach ($posts as $post) {
        foreach ($post as $field) {
             unset($field['categories']); //i want remove this
             unset($field['author']); //i want remove this
	     unset($field['type']);  //i want remove this
	}

    }

    $result = $this->posts_result($posts);

    $result['query'] = $query;
    return $result;
  }

What i’m doing wrong?

Thank you 🙂

Yes but i want to exclude a lof of things (and the url could be too much longer with all the exclude arguments)

I’ve solved editing get_recent_post in core php

public function get_recent_posts() {
    global $json_api;
    $posts = $json_api->introspector->get_posts();
	foreach($posts as $post){

		$post->content = strip_tags($post->content, "<p>");

		foreach ($post->attachments as $attachment){

                        unset($attachment->images['full']);
                        unset($attachment->images['medium']);
                        unset($attachment->images['large']);
                        unset($attachment->images['bones-thumb-300']);
                        unset($attachment->images['bones-thumb-600']);
                        unset($attachment->images['post-thumbnail']);
                        unset($attachment->images['vendor-thumb']);
                        unset($attachment->images['0']);
			unset($attachment->images['et-featured-first']);
			unset($attachment->images['et-featured-second']);
			unset($attachment->images['et-featured-category']);
			unset($attachment->images['et-featured-third']);
			unset($attachment->images['et-recent-post-image']);
			unset($attachment->images['et-popular-post-image']);
			unset($attachment->images['et-popular-post-big-image']);
			unset($attachment->images['et-category-image']);
			unset($attachment->images['et-recent-first-image']);
			unset($attachment->images['et-tabs-image-small']);
			unset($attachment->images['et-blog-page-thumb']);
			unset($attachment->images['et-gallery-page-thumb']);
			unset($attachment->images['et-portfolio-medium-page-thumb']);
			unset($attachment->images['et-portfolio-medium-portrait-page-thumb']);
			unset($attachment->images['et-portfolio-small-page-thumb']);
			unset($attachment->images['et-portfolio-small-portrait-page-thumb']);
			unset($attachment->images['et-portfolio-large-page-thumb']);
			unset($attachment->images['et-portfolio-large-portrait-page-thumb']);
        }

		unset($post->thumbnail_size);
		unset($post->thumbnail_images);
		unset($post->custom_fields);
		unset($post->slug);
		unset($post->excerpt);
	}
    return $this->posts_result($posts);
  }

Take this solution inside a custom controller:

$query = array(
            'post_type' => 'objekt',
            'include' => 'title,author'
        );

        /*
         * WORKAROUND by nerevo
         */
        if ($query['include']) {
            $json_api->response->include_values = array_merge($json_api->response->include_values, explode(',', $query['include']));
        }

        $posts = $json_api->introspector->get_posts($query);
