How to add value to Post Object field in ACF via code?
I need to add value through update_fields through code.


The normal embed code in the field doesn't work. Here is the code:

$value[] = array("perks" => 9999);
update_field($field_key, $value, $post_id);

Tried like this: And like this: Maybe superfluous, but nothing works (I would be very grateful if you help
$value = array("perks" => 9999);

$value[] = array(9999);
