im going to add custom fields to post title ,

my post title is "Marroon Five" and my custom fields is "release-year" and with value "2017" .

so how to make the output : Marroon Five (2017)

this is what i found after doing some searching

add_action('save_post', 'update_term_title');
function update_term_title($post_id)
{
    if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) 
        return;
    if(!current_user_can('edit_post', $post_id))
        return;

    //Replace 'release-year' with whatever your custom taxonomy slug is
    $terms = wp_get_post_terms($post_id, 'release-year');

    if(empty($terms))
        return;

    $title = false;
    foreach($terms as $term)
    {
        if($term->parent)
        {
            $parent = get_term($term->parent, 'muviyear');
            $title = $term->name.' '.$parent->name;
            break;
        }
    }
    /*Default to first selected term name if no children were found*/
    $title = $title ? $title : $terms[0]->name;

    /*We must disable this hook and reenable from within
    if we don't want to get caught in a loop*/
    remove_action('save_post', 'update_term_title');
    $update = array(
        'ID'=>$post_id,
        'post_name'=>sanitize_title_with_dashes($title),
        'post_title'=>$title
    );
    wp_update_post($update);
    add_action('save_post', 'update_term_title');
}

the only problem is this code replace all the post title with custom field value which is "2017"

hope someone can fix this is return output as i wanted to
