<?php

function my_acf_save_post( $post_id ) {
    // bail early if no ACF data
    if( empty($_POST['acf']) ) {
        return;
    }
    // specific field value
    $my_new_slug = $_POST['acf']['my-slug-part1'].'-'.$_POST['acf']['my-slug-part2'].'-'.$_POST['acf']['my-slug-part3'];
    $post = array(
      'ID' => $post_id,
      'post_name' => $my_new_slug
    );
    wp_update_post($post);
}

// run before ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 1);
