输出WordPress帖子的JSON

Question

I am using JSON-API plugin for WordPress and I am creating a custom controller that returns a list of posts from a post type. The output I want is something like this:

[{
    "id": 1,
    "title": "Sample Post Title"
},
{
    "id": 2,
    "title": "Sample Post Title"
},
....
]

here is my custom controller:

class JSON_API_Custom_Controller {

 public function get_posts_type() {
    global $json_api;

    $posts_all     = array();

    $args = array( 'post_type' => 'shopping', 'posts_per_page' => -1);
    $loop = new WP_Query( $args );
    if ( $loop->have_posts() ) {
      while ( $loop->have_posts() ) : $loop->the_post();
        $post_id = get_the_ID();
        $post_title = get_the_title($post_id);

        $posts_all []= array(
         'id' => $post_id,
         'title' => $post_title
        );

      endwhile;
    }

   return $posts_all;

  }

}

but the output is :

{  
   "status":"ok",
   "0":{  
      "id":1,
      "title":"sample title"
   },
   "1":{  
      "id":2,
      "title":"sample title"
   }
}

how can I output the json array of objects like the desired output?

Answer 1

I suppose adding status:ok to json response is a feature of a plugin.

So, you can modify you function to return an array with one key:

// not this 
//return $posts_all;

// but this
return array('posts' => $posts_all);

After that, you will still have status key in your json response, but also you will have posts key, that you can iterate over.

Update: I suppose, the filter json_api_encode may help you. You can unset status key there:

add_filter('json_api_encode', 'remove_status');

function remove_status($response) {
    unset($response['status']);

    return $response;
}

Answer 2

Hope the below code will do that for you.

 return json_encode($posts_all);

To get that "Status" as in example output, you need to add the same in your code.
