Need to 'prepare_post' data

It’s seems like i found a related request here:

just posting my response (https://www.ads-software.com/support/topic/a-way-to-utilize-the-json-rest-api-libraries-to-generate-embedded-post-json) to my question here as well, thanks for linking the similar questions @kindom creation

@kingdom creation, sorry i meant to post an update, but i got caught up in meeting a deadline. some of this was due to me still learning the WordPress Way, where i came from a MVC Framework background, but basically you can refer to the global in your function like so:

global $wp_json_posts;

and utilize the get_post() method, passing in post_id, and ‘child’ to indicate recursive lookups or embedding, example below:

$wp_json_posts->get_post( $post_id, ‘child’ );

the one caveat is make sure your method that will use this has access to the children post_ids, which it looks like it does based on your pasted code.

happy coding,

Hi,

It seems that the variable global $wp_json_posts; is undefined in my context. I believe this may be somehow related to the fact that i’m using it outside the server process upon save_post.

Currently i’m converting a large array that contains ‘WP_Post’ and authors and all kinds of WordPress data objects.

I considered parsing the properties and renaming the indexes kinda like the api does in ‘prepare_post’ but it just seems so redundant.

What i do then is save the data in a post_meta. ( and i would like it to be saved formatted the same way the api does). In another context i then pull the data back when that api summoned, I use the fillowing code.

functions.php

add_filter( 'json_prepare_post', function ($data, $post, $context) {
	$data['post_meta'] = get_post_meta( $post['ID'],'_data', true );
	return $data;
}, 10, 3 );

But as you can see above in my original question, the json from the api is formatted by the api to look nice and be useful (author instead of post_author, with meaningful data inside not just an index) but the data i added ‘post_meta‘ contains some data that isn’t nicely formatted.

All i would need really would be the create an instance of the WP_JSON_Posts but the authors @ryanmccue made it so i think it shoulnt be instantiated outside of it’s server component.

Although the function ‘get_post’ (witch i think is the one @rjvansant suggested would be super useful. and is basically what i need, it’s right there just i can use it in the admin)

So i considered, what if i use PHP to query the API and get the formatted data that way, i tried curl, i tried file_get_contents etc. even i tried to get @ryanmccue php-client in my theme….

1. . Is there a way to reuse the api formatting blocs used ‘in’ the api outside the api.

The other hook inside my function is

add_action('save_post', 'update_data',20,1);

function update_data($post_id){
  <em> global $wp_json_posts; // @rjvansant</em>
   ...
}

Thanks! @rjvansant
