Hi, i have group filed with few sub fields and i want to fill it with data. Using if( have_rows('fotografie') ): while( have_rows('fotografie') ) : the_row(); doesnt work because it doesnt have any row yet. add_row() didnt work either. Anyone know how to do this?

When updating a field that does not exist yet you need to use the field key rather than the field name.

When dealing with a group field, it can only have one row so I would bypass the loop and add_row and to

$value = array(
  // sub field key/value pairs
  'field_12345' => 'value 1',
  'field_34567' => 'value 2',
  // etc....
);
update_field('field_xyz123', $value, $post_id);
