Looking to add the parent id to each resulting posts/pages for rest api

Hi, @shuangmiles. Do you only need access to the parent ID via the response? The rest response should have a parent ($post->parent) field for each of the post objects, judging by the code here: https://developer.www.ads-software.com/reference/classes/wp_rest_posts_controller/prepare_item_for_response/

Or, is it a requirement to separate the parent ID in the returned response?

Yeah I need it in the rest response. I don’t see any sortof parent id in the objects in the array.

Do you mind sharing what the response object/array looks like? Not sure if you’re grabbing this via PHP or JS on the other end. I haven’t worked much with the REST API, but I’ll be happy to see if we can figure this out together.

Also, can you share your full function/method code from above? There might be something that we’re missing outside of the code snippet.

Here is the full function

function relevanssi_search_route_callback( WP_REST_Request $request ) {

	$parameters = $request->get_query_params();
  
	// Force the posts_per_page to be no more than 12
	if ( isset( $parameters['posts_per_page'] ) && ( (int) $parameters['posts_per_page'] >= 1 && (int) $filter['posts_per_page'] <= 12 ) ) {
	  $posts_per_page = intval( $parameters['posts_per_page'] );
	} else {
	  $posts_per_page = 12;
	}

	$page_number = isset( $parameters['page'] ) ? intval(intval($parameters['page'])) : 1;
  
	  // default search args
	  $args = array(
		's'               =>  $parameters['s'],
		'no_found_rows'=> true,
		'paged' => $page_number  ,
		'posts_per_page'  =>  $posts_per_page,
		'post_status' => 'publish',
		'ignore_sticky_posts' => true,
		'post_type'        => array('post', 'page')
		// 'fields' => 'id=>parent'
	  );
  
	  // run query
	  $search_query = new WP_Query();
	  $search_query->parse_query( $args );
	  if ( function_exists( 'relevanssi_do_query' ) ) {
		relevanssi_do_query( $search_query );
	  }
  
	  $controller = new WP_REST_Posts_Controller('post');
	  $posts = array();
  
	//   foreach($search_query->posts as $po) {
	// 	  $po->parent_id = &quot;test&quot;;
	//   }

	  while ( $search_query->have_posts() ) : $search_query->the_post();
	    // $search_query->post->test = &quot;Test&quot;;
		$data    = $controller->prepare_item_for_response( $search_query->post, $request );
		$posts[] = $controller->prepare_response_for_collection( $data );
	  endwhile;

	//   foreach($posts as $post) {
	// 	  $post['parent_id'] = wp_get_post_parent_id($post->$id) ;
	//   }

	  $results = array();
	  $results['total_results_count'] = $search_query->found_posts;
	  $results['posts'] = $posts;
  
	// return results
	if( ! empty( $posts ) ) {
	//   return new WP_REST_Response( $posts, 200 );
	return new WP_REST_Response( $results , 200 );
	} else {
	  return new WP_Error( 'No results', 'Nothing found' );
	}
  
  }

What does the response look like from the API? I’m assuming you’re getting this via PHP or JavaScript on the other end.

I’m using JS, each post/page data is rather large but none of the keys that it has includes parent id or even any of the test keys that I tried inserting through php. I tried to loop through each and assign a new key to equal the result of wp_get_post_parent_id but that doesn’t seem to show up.

Can you at least provide a sample of the data? I doesn’t have to be the entire object.

It should look something like:

{
	"total_results_count": 10,
	"posts": [
		{
			"id": 100
			...
		}
	]
}

Specifically, I’m trying to figure out what data is appearing for individual post objects.

{
	"total_results_count": 10,
	"posts": [
		
{
      "id": 26397,
      "date": "2020-07-10T12:33:42",
      "date_gmt": "2020-07-10T12:33:42",
      "guid": {
        "rendered": ""
      },
      "modified": "2022-04-19T19:57:14",
      "modified_gmt": "2022-04-19T19:57:14",
      "slug": "video-testimonials",
      "status": "publish",
      "type": "page",
      "link": "https://81acf57d5a.nxcli.net/video-testimonials",
      "title": {
        "rendered": "Video Testimonials"
      },
      "content": {
        "rendered": "",
        "protected": false
      },
      "excerpt": {
        "rendered": "",
        "protected": false
      },
      "author": 1,
      "featured_media": 0,
      "comment_status": "closed",
      "ping_status": "closed",
      "sticky": false,
      "template": "",
      "format": "standard",
      "meta": {
        "inline_featured_image": false
      },
      "categories": [
        
      ],
      "tags": [
        
      ],
      "yoast_head": "",
      
        ]
      }
	]
}

Something has already filtered the response. There are normally “parent” and “menu_order” fields between “featured_media” and “comment_status”.

Do the deactivate plugins and switch to a default theme debugging procedure. The missing fields should appear. Restore your theme and plugins, one at a time, testing after each. When the fields again disappear, the last activated is the cause.

You have $post['parent_id'] in commented code. FWIW it should be $post['parent']. There could be a similar error elsewhere, I didn’t look that closely.
