Get parent key instead of id

On one WP installation I got the key (field_xxxxxx) under the parent key of a field object, and under another installation I got the WP Post ID of the field instead of the key.

Can I configure that? What could be the cause?

You need to give more detail? I don’t know what you are referring to.

Seems to be the same as described here: https://support.advancedcustomfields.com/forums/topic/use-parent-key-to-get-the-parent-field-object/

So, once using the ACF PHP functions to get a field object, via for example get_field_object(), the returned array holds the post ID of the parent field under the ['parent'] key.

While on another WordPress installation, under the exact same function returns the ACF key of the parent instead of the post ID.

How do I make sure, that I always receive the key value and not the ID value?

I still don’t know the answer or why parent is an ID in one case and the field key in others. I have never run into this.

Please see the attached screenshot, which is a dump of get_field_object().

That does not tell my why it is an ID in this case but it is a field or group key in a different case.

The only think I can thing of in this that it’s a field key when loaded in JSON or created in PHP and a post ID when it is loaded from the DB.

I have looked and I don’t see any simple way to convert that ID into a Key.

You can try

$field_group = acf_get_field_group($id);
$key = $field_group['key'];
