I tried:

function my_acf_post_fieldb($post){
$post_id = get_the_id();
$post_author_id = get_post_field( ‘post_author’, $post_id );
$field[‘readonly’] = 1;
$field_key = “field_573d8df4646da”;// field_key of repeater field
$value = array(
array(
“c_address1” => “Foo”,
“c_address2” => “Bar”
)
);
$field = update_field($field_key, $value);
return $field;
}
add_filter(‘acf/save_post hook’, ‘my_acf_post_fieldb’);

and it isn’t working either. The fields are not being populated with values.
What do I need to return out of the function? I tried return $post; it doesn’t work either.
