I am using Metabox.io, and I have a certain Custom Post Types. Right now I am using a Destination CPT, which has a field type -> post. Now I am rendering the other CPT through that. Everything works fine, except the REST API response. It only shows the CPT ID attached to the Destination CPT.

I want to show the Object Data in the Destination CPT of another post type which is embedded in it.

JSON OUTPUT
```
"meta_box": {
   "prefix-destination-story-field": ["535"], 
   "prefix-destination-gallery-field": ["269"],
   "prefix-destination-video-gallery-field": ["280"],
   "prefix-destination-trip-field": [ "236" ]
}
```
This is the link for Field Type Post: Metabox Post Type Field

I need to know how should be able to populate an object inside the array of metabox-id?

Any help would be appreciated. Let me know if I can produce any thing else to give you a clear insight of what I am asking for.

Hi Sharath,

The values are returned via function rwmb_get_value and it has a filter with the same name rwmb_get_value for you to modify the values.

So, I think you can do something like:

add_filter( 'rwmb_get_value', function( $value, $field, $args, $post_id ) {
    // Change value only for REST API.
    if ( ! defined( 'REST_REQUEST' ) ) {
        return $value;
    }

    if ( 'your_field_id' !== $field['id'] ) {
        return $value;
    }

    // Modify your value here.
    return $value;
}, 10, 4 );

Thanks for the reply Anh, but did not work out for me.

So here is the code in my Destination CPT, I have tried getting the data from the field_id: prefix-destination-story-field, as you can get it from my question too.

But the API result was same as before. Here is what I've tried, I did not see any other object either.


//for object info filter
add_filter( 'rwmb_get_value', function( $value, $field, $args, $post_id ) {
    // Change value only for REST API.
    if ( ! defined( 'REST_REQUEST' ) ) {
        return $value;
    }

    if ( 'prefix-destination-story-field' !== $field['id'] ) {
        return $value;
    }

    // Modify your value here.
    return $value;
}, 10, 4 );

JSON RESPONSE


"meta_box": {
  "prefix-destination-story-field": ["535"],
  "prefix-destination-gallery-field": ["269"],
  "prefix-destination-video-gallery-field": ["280"],
  "prefix-destination-trip-field": ["236"]
}

If you want I will show you the full code of that CPT.

Hey Sharath,

Please don't just copy and paste my code. I put a comment "Modify your value here", which means you should get the post details from the post ID ($value) there. Something like this:

add_filter( 'rwmb_get_value', function( $value, $field, $args, $post_id ) {
    // Change value only for REST API.
    if ( ! defined( 'REST_REQUEST' ) ) {
        return $value;
    }

    if ( 'p' !== $field['id'] ) {
        return $value;
    }

    $value = get_post( $post_id, ARRAY_A );
    return $value;
}, 10, 4 );

Hey Anh, thanks for the help. It was indeed helpful, although, there is one catch. That is I cannot see the meta_box response inside the REST API response of prefix-destination-story-field. Could you please tell me how can I add/show the <string>meta_box of the Custom Post Type Story inside the Destination CPT in the response. Here is the response, with the code.

Code:


add_filter( 'rwmb_get_value', function( $value, $field, $args, $post_id ) {
    // Change value only for REST API.
    if ( ! defined( 'REST_REQUEST' ) ) {
        return $value;
    }

    if ( 'prefix-destination-story-field' !== $field['id'] ) {
        return $value;
    }
    
    $arr = [];
    $ids = get_post_meta($post_id, 'prefix-destination-story-field', false);
    //$value = get_post( $id, ARRAY_A);
    foreach ($ids as $id){
        array_push($arr, get_post($id, ARRAY_A));
    }
    return $arr;
    
}, 10, 4 );

API RESONSE:


"meta_box": {
   "prefix-destination-story-field": [
     {
        "ID": 535,
        "post_author": "1",
        "post_date": "2019-10-24 12:42:39",
        "post_date_gmt": "2019-10-24 12:42:39",
        "post_content": "This is demo story content",
        "post_title": "Hello Story",
        "post_excerpt": "",
        "post_status": "publish",
        "comment_status": "closed",
        "ping_status": "closed",
        "post_password": "",
        "post_name": "hello-story",
        "to_ping": "",
        "pinged": "",
        "post_modified": "2019-10-24 16:39:25",
        "post_modified_gmt": "2019-10-24 16:39:25",
        "post_content_filtered": "",
        "post_parent": 0,
        "guid": "",
        "menu_order": 0,
        "post_type": "story",
        "post_mime_type": "",
        "comment_count": "0",
        "filter": "raw",
        "ancestors": [],
        "page_template": "",
        "post_category": [],
        "tags_input": []
     }
  ]
}

As you can clearly see in the response, that the meta_box is not shown. However, in this prefix-destination-story-field, there are meta-boxes linked with it. Thanks. Will appreciate this last help of yours. Thanks 🙂

As this is a custom code to fetch post data, there won't be a field meta_box in the post details. You can add a specific meta value if you want, like this:

$arr = [];
$ids = get_post_meta($post_id, 'prefix-destination-story-field', false);
foreach ($ids as $id){
    $value = get_post($id, ARRAY_A);
    
    // THIS
    $value['field_id1'] = rwmb_meta( 'field_id1', '', $id );
    $value['field_id2'] = rwmb_meta( 'field_id2', '', $id );

    array_push($arr, $value);
}
