I have opened up a support ticket on this, but thought you other forum devs might be able to help…
I was wondering if there was a way to ensure the post/page/cpt ‘Title’ field is validated / not left blank via ACF. Amazingly clients still do this!
Alternatively is there a way to populate the post title, and thus slug, based on an ACF field.
I will update with any response from support.
For anyone else, I had a response from ACF support as follows…
But if you use the filter acf/save_post you can call any php you want from there, so you could update the page title from there.
Have a look at the docs above, hopefully that will get you where you need 🙂
