Umm, yeah, I guess it’s not that simple and I should have know that. We only want to have it run if there are ACF field being submitted.
add_action('init', 'see_whats_posted');
function see_whats_posted() {
if ((!defined('DOING_AJAX') || !DOING_AJAX) && isset($_POST['acf'])) {
echo '<pre>'; print_r($_POST['acf']); die;
}
}
Once this is set up go to the page with the field you can’t set to empty, clear the value and save the post. What this will do is, when you submit a post with ACF fields it will show the values submitted and exit PHP. This will let you see if the empty value in the field is submitted.
