I’m looking for an answer how to generate a post title using acf_form. I would like to generate the title from two or three custom fields. However everything I try I cannot get the front end form to generate a post title.

My current code for the front end form is;

acf_form(array(
                             'post_id' => 'new_post',
                             'field_groups' => array(220), 
                             'post_title' => false, 
                             'post_content' => false,
                             'form' => true,
                             'new_post' => array(
                                 'post_type' => 'setups_2019',
                                 'post_status' => 'publish',
                             ),
                             'return' => '%post_url%',
                             'submit_value' => 'Submit Setup',
                         ));

You need to create either an acf/pre_save_post or an acf/save_post filter. Since you’re using the built in acf/pre_save_post filter I would go with an acf/save_post filter.

add_action('acf/save_post', 'update_setups_2019_title');
function update_setups_2019_title($post_id) {
  if (get_post_type($post_id) != 'update_setups_2019') 
    // only run on your post type
    return;
  }
  // get the post
  $post = get_post($post_id);
  // update the post title
  $post->post_title = get_field('field-one').' '.get_field('field-two'); // etc..
  // correct the slug.. optional and I don't know that this is 100% correct
  $slug = sanitize_title($post->title);
  $post->post_name = wp_unique_post_slug($slug, $post->ID, $post->post_status, $post->post_type, $post->post_parent);
  // remove this filter to prevent infinite loop
  remove_filter('acf/save_post', 'update_setups_2019_title');
  // update the post
  wp_update_post($post);
  // re-add this filter
  add_action('acf/save_post', 'update_setups_2019_title');
}
