This is no longer needed. You can access it through either $_POST[‘post_id’] for post types or $_POST[‘_acf_post_id’] on options pages.

I know this is an old post, but it’s still a relevant need even now. I didn’t like the proposed solution, so I set out to find an alternative. My solution is a lot simpler – the post_id is POSTed upon submit, and accessible during validation. Simple reference $_POST[‘post_id’] to access the post_id. No need to create hidden fields to pass what’s already being passed.

In reply to Michael. Sorry, just saw this comment - I double checked the syntax and it looks correct to me. You could try moving lines 6-9 to one line (I formatted it that way to make it easier to read). Also make sure that none of the quotation marks are being translated into something fancy.

In reply to Michael. Hi Michael - which command are you running when you get that error? It's important that everything be copied exactly you you may run into syntax errors. Good luck!

Good call on not needing is_admin() – I copied this from Validated Field which does some other things that do require the admin check. Since I wrote this post I realized it’s probably prudent to use something like acf[my_unique_sub_array][post_id] or similar to prevent conflicts with ACF should you ever have a field named post_ID. A lot of new features being added in version 2.0 if you care to check it out: https://github.com/doublesharp/validated-field-for-acf

Fantastic contribution! The post ID should be in the validate hook but this is a perfect workaround

The conditional is_admin() is not required, since edit_form_after_editor only fires in the editor anyway
