Combine relationship posts with existing wp_query

So I am building a query, and I wanted to see if someone can assist me on a special attempt to infuse two queries.

So here is what I’m attempting to do:

  1. Check if we have any relationship posts, which I can return either an array of IDs or an array of WP_Post objects.

  2. I want to showcase the relationship posts first if they are and then showcase the remaining wp_query posts.

Here is what I’m working with:


Original:

$  args = [     'post_type' => ['work', Report_Type::CPT_NAME],     'posts_per_page' => 4,     'post_status' => ['publish'], ]; $  query = new WP_Query($  args); 

Then I’m looping through using a template as shown below:

if ($  query->have_posts()) {     ob_start();     get_template_part('template-parts/blocks/work-expertise-filter/work-items-template', null, ['query' => $  query]);     $  content = ob_get_contents();     ob_end_clean();     wp_reset_postdata(); } 

So let’s say, that I have get_field('featured_posts') which returns back an ARRAY of IDs (I can check it to ARRAY of WP_Post objects if needed).
This is our return: array(2) { [0]=> int(14244) [1]=> int(14566) } array(4) {

So I attemped to do something like this:

    $  args = [         'post_type' => ['work', Report_Type::CPT_NAME],         'posts_per_page' => 4,         'post_status' => ['publish'],     ];     $  query = new WP_Query($  args);      $  all_ids = [];     if ($  query->have_posts()) {         while ($  query->have_posts()) {             $  query->the_post();             $  all_ids[] = array_merge($  query->post->ID, get_field('featured_posts'));         }         wp_reset_postdata();     }     $  all_ids = array_unique($  all_ids);     $  args = [         'post__in' => $  all_ids     ];     $  the_query = new WP_Query($  args); 

But I’m getting no response back, it’s basically: object(WP_Query)#1853 (50) { [“query”]=> array(1) { [“post__in”]=> array(1) { [0]=> NULL } } [“query_vars”]=> array(63) { [“post__in”]=> array(1) { [0]=> NULL }

If someone could help me with a query, it would be much appreciated!
