Hi @pmallek and @edering
You should be able to do it by using the update_field() function. It should be something like this:
// the post ID
$post_id = 99;
// get the repeater values
$repeater = get_field('repeater', $post_id);
// update the google map field ('repeater_google_map') in the second row ('1')
$repeater[1]['repeater_google_map'] = array(
'address' => '322 Little Bourke St, Melbourne VIC 3000, Australia',
'lat' => '-37.81310659591412',
'lng' => '144.96356964111328'
);
// update the field
update_field('field_1234567890abc', $repeater, $post_id);
Where ‘field_1234567890abc’ is the repeater field key and ’99’ is the post ID.
I hope this helps 🙂
