Hello friends,

I am developing a custom theme and in some post type edit screens I need to have some fields, so I did it with acf.

when admin fills the fields and press publish, I do something using ajax and I do not need to save any fields in wp_postmeta table.

I mean just appearance and displaying of fields is enough for me, How can I drop fields saving process?

Thanks in advance.

You can hack this by creating an acf/save_post action that runs before ACF (priority < 10) https://www.advancedcustomfields.com/resources/acf-save_post/

In this action you test test for the post type and if it is your post type you can unset the ACF data

unset($_POST['acf']);

Alternately, if you only want this to happen for certain fields you can unset the value of that field key specifically

unset($_POST['acf']['field_123456']);
