Tell us what you are trying to do? create a child post using a from and give it a dynamic name with data from the parent post

Is there any documentation that you are following?

https://toolset.com/forums/topic/cannot-get-parent-post-id-on-cred_save_data-with-new-relationships-api/#post-1121934

Is there a similar example that we can see?
not sure

I have tried multiple solutions but couldn't get this to work.
i can create a dynamic name for a post but cannot get the parent data to insert to the child post.
both parent and child posts are with status Private

here is one of the codes i tried

//Create a dynamic post title by the CRED form.
add_action('cred_save_data', 'func_custom_post_title', 10, 2);
function func_custom_post_title($post_id, $form_data)
{
	$author = get_the_author();
	$user_id =  get_the_author_meta('ID');
	//if new client - parent post dynamic name works just fine
	if ($form_data['id'] == 283 ) {
		$author = get_the_author();
		$user_id =  get_the_author_meta('ID');
		$post_type = get_post_type( $post_id ); 
		$cfn = get_post_meta($post_id, 'wpcf-client-first-name', true);
		$cln = get_post_meta($post_id, 'wpcf-client-last-name', true);
		$cshrtid = get_post_meta($post_id, 'wpcf-client-id-number', true);
		$title = $cfn.' '.$cln.' '.$user_id.'-'.$cshrtid.'-'.$post_id;
		$slug = sanitize_title($title);
		$args = array('ID' => $post_id, 'post_title' => $title, 'post_name'=>$slug);
		wp_update_post($args);
	}
	//if new portfolio -child post cannot get the parent post data so this is not working
	if ($form_data['id'] == 386 ) {
		
//get data from parent post i tried this option
		$parent_post_id = toolset_get_related_post( $post_id, 'client-client-portfolio', 'client' );		
		
// and i tried this option
		$child_post_id = get_post($post_id);
		$parent_post_id = toolset_get_related_post( $child_post_id, 'client-client-portfolio', 'parent');
		
		$cfn = get_post_meta($parent_post_id, 'wpcf-client-first-name', true);
		$cln = get_post_meta($parent_post_id, 'wpcf-client-last-name', true);
		$cshrtid = get_post_meta($parent_post_id, 'wpcf-client-id-number', true);
		//get data from current post		
		//$post_type = get_post_type( $post_id );
		// Get the title of the parent (client) post
		$title = $cfn.' '.$cln.' '.$user_id.'-'.$cshrtid.'-'.$parent_post_id.'-P'.$post_id;
		$slug = sanitize_title($title);
		$args = array('ID' => $post_id, 'post_title' => $title, 'post_name'=>$slug);
		wp_update_post($args);
	}
}

please advise,
thanks,

Dear David,

I assume we are talking about same website as your previous thread:
https://toolset.com/forums/topic/display-parent-data-on-a-child-post/#post-1157554

I have checked the database dump file again, in the form ID 386, there is a hidden parent post selector, after user submit the form, it will pass a POST parameter "@client-client-portfolio_parent" to target page, so you will can get the parent post ID with below codes:

$parent_post_id = $_POST['@client-client-portfolio_parent'];
