Hi @edcraddock,

I’m trying to do the same thing. Basically, what you need to do is add a hook on saving the post, and assemble the title from the components.

add_action('acf/save_post', 'my_save_post');
function my_save_post($post_id){
  // make sure this post type is the kind we want

  // get the first and last name fields
  // (or whatever field(s) you want to convert into the title

  // update the post title (if there isn't one already)
  // https://developer.wordpress.org/reference/functions/wp_update_post/
}

I’m using this help page to figure this out: https://www.advancedcustomfields.com/resources/using-acf_form-to-create-a-new-post/ (look at the contact form example)

the acf/save-post hook happens AFTER the post is inserted, so you can use wp_update_post to update the title.

(I’ll post my code here once I actually get it working)

Ah, good ol’ undocumented functions. Thanks for the reference, that’s going to help a lot.

Hmm. How do I unmark my solution so I can flag yours?

Well, after posting (isn’t it how this always works?) I figured out the brute force way to do it. It would be great if there were a function for this.

// get the list of fields in order.
	
$args = array(
	'post_type' => 'acf-field',
	'post_parent' => $group_id, // field group 
	'posts_per_page' => 100,
	'orderby' => 'menu_order',
	'order' => 'ASC'
);
	
$all_fields = new WP_Query($args);
	
$fieldnames = array();

if ($all_fields->have_posts()){
	foreach($all_fields->posts as $f){
		$fieldnames[] = $f->post_excerpt;
	}
}
		
// get the fields

$fields = get_field_objects();

if( $fields )
{

	foreach($fieldnames as $fn){
		
		if (isset($fields[$fn])){
			$field =  $fields[$fn];
			if ($field['value'] == '') continue;
			/* do stuff */
		}
	}
}
