Hi,
I’m tryng to update both parent and child post title while saving the parent post.
The parent post is updated, but the child post is not updated. What am I doing wrong?
Thanks in advance…

 function post_title_attestato_fune_updater( $post_id ) {

    $fune_post = array();
    $fune_post['ID'] = $post_id;
	
    
	$companies = get_field('spettle');
	foreach($companies as $company){
    $company_name = $company->post_title;
    $company_id = $company->ID;
    $company_name;
      }
	  
	$matricole_post = array();
    $matricole_post['ID'] = $post_id; 
	  
	$matricole = get_field('matricola');
	foreach($matricole as $post){
    $matricola_name = $post->numero_di_fabbrica;
	$matricola_macchinario = $post->tipo_di_macchinario;
    $matricola_id = $post->ID;
    $matricola_name;
	$matricola_macchinario;
      } 

    if ( get_post_type() == 'fune' ) {
		$pipe = ' - ';
		
	  $fune_post['post_title'] = $company_name . ' ' .$pipe . '  ' . $matricola_macchinario . '  ' .$pipe . '  ' . $matricola_name;
    } 

    // Update the post into the database
    wp_update_post( $fune_post );
	
//until here everything goes well, but I can't update the child post below	
  
     if ( get_post_type() == 'annotazioni' ) {
		$pipe = ' - ';	
		
	  $annotazioni_post['post_title'] = $company_name . ' ' .$pipe . '  ' . $matricola_macchinario . '  ' .$pipe . '  ' . $matricola_name;
    } 
	   wp_update_post( $annotazioni_post );	
  }
