Hello!
I’m sorry for revive this old thread.
Is there a filter for the Custom Storage?
I’d love to do something like this:
add_filter( 'acf/tell_me_the_hook', function( $custom_storage) { return 'user_' . $_GET['used_id']; } );
This way, I could dynamically edit the custom fields for the user_id passed via the URL.
Of course, this is a very simple example and the final code would have validations and more complex stuff… but I can’t find a hook like this in the documentation.
Thanks in advanced for your reply!
