Pretty sure you can add the title to the new post like so:
<?php
acf_form(array(
'post_id' => 'new_post',
'post_title' => false,
'post_content' => false,
'new_post' => array(
'post_type' => 'tickets',
'post_status' => 'publish',
'post_title' => 'my title'
),
fields' => array('field_5ba8b0c6a5116', 'field_5ba8b08c96be1'),
);
?>
Seems nicer, but you don’t have access to the new post ID 🙁
