As soon as I create a new field in a group via the WordPress admin, a second field of type text is automatically created. The keys of the fields are “26017” and then “field_60efcd5f9a084”.
At the same time, when I click on update, I also lose the position where everything should be displayed. It resets itself to post. The Original Position it should be displayed on is an options page.
I have 204 Fields (Text fields + repeater) in this Group. And fieldnamens can be something like this “language_mybikes_modals_angebot_nicht_mehr_verfugbar_bodytext_start”.
So a very long name.
So i just googled für acf losing postion and came up with a solution to increase max_input_vars. It was 1000, then increase it to 3000 and my problems are gone.
Now my Question to this.
Can this really be the reason for the problems described.
Is there a way to determine how long the string (or how many vars) is that ACF produces at the moment I click on update.
And gives a recommended value for max_input_vars.
Probably in 99.9% of all cases the 1000 for max_input_vars is by far enough.
You have 204 fields. When creating fields the basic field (a text field) has 14 input fields. 204*14 = 2856 fields submitted. Other field types have even more inputs.
I’d also be surprised if your not having an issue with meta_key lengths with field names like “language_mybikes_modals_angebot_nicht_mehr_verfugbar_bodytext_start”
