  • Here is how I would go about it, untested code.

    First a function to extract the names from $_POST, by adding an action to acf/save_post()

    function pre_save_user_fullname($post_id){
      if( empty($_POST['acf']) ) { return; }
      $firstname = $_POST['acf']['FIRST NAME FIELD KEY'];
      $lastname = $_POST['acf']['LAST NAME FIELD KEY'];
      $fullname = $firstname.' '.$lastname;
      return $fullname;
    add_action('acf/save_post', 'pre_save_user_fullname', 21);

    Then modifying the post data before it is written to db, by filtering wp_insert_post_data();

    function user_fullname_as_post_title( $data, $postarr ) {
        if ( ! $postarr['ID'] ) return $data;
        if ( $postarr['post_type'] !== 'YOUR_POST_TYPE' ) return $data;
        $post_id = $postarr['ID'];
        $fullname = pre_save_user_fullname($post_id);
        if( empty($fullname) ) { return $data; }  
        $data['post_name'] = $fullname;
        return $data;
    add_filter( 'wp_insert_post_data', 'user_fullname_as_post_title', 99, 2 );

    If it doesn’t work, I hope it at least helps.
