Kirby 3 Solved ✅

No sorry, also not working! Everytime I do this request at a english page, all field datas are deleted … Do I understood this wrong? I wanted to put in all data that are collected only to the german file. Full code:

$kirby = kirby();
$kirby->impersonate('kirby');

function addToStructure($page, $field, $data = array()){
  $fieldData = page($page)->$field()->yaml();
  $fieldData[] = $data;
  $fieldData = yaml::encode($fieldData);
  try {
    page($page)->update(array($field => $fieldData),'de');
  } catch(Exception $e) {
    return $e->getMessage();
  }
}
 
addToStructure(page('conversions'), 'nachrichtenverlauf',[
  'nachrichtenverlauf_art' => 'Preisanfrage',
  'nachrichtenverlauf_fahrzeug' => $preisliste,
  'nachrichtenverlauf_datum' => $datum,
  'nachrichtenverlauf_uhrzeit' => $uhrzeit,
  'nachrichtenverlauf_email' => $email,
  'nachrichtenverlauf_sprache' => $sprache
]);

$kirby->impersonate();
