I quickly looked under the hood and found a few things about my issue:
– The ‘save_post’ hook isn’t firing when I update a Page. Not sure exactly why…documentation is slim even though this is a common problem…but perhaps we should hook the acf_admin_field_group::save_post() method to ‘pre_post_update’ instead?
– The ‘field_group’ nonce can fail when there are multiple field groups. This writes multiple ‘_acfnonce’ hidden inputs to the page’s form. The last input value stomps the other nonce values (which don’t appear in the POST params). Perhaps the _acfnonce value should be keyed to each particular field group?
I would be happy to contribute code to fix these issues if you give the thumbs up, Eliot.
Hope that helps.
